From 249f5c7aab29e0238b5c6eff6de89ee4ac111e97 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Gerg=C5=91=20Magyar?= Date: Sat, 18 Jul 2026 20:50:14 +0100 Subject: [PATCH 01/91] fix(lbug): bound the LadybugDB buffer pool instead of the native 80%-of-RAM default (#2560) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(lbug): bound the LadybugDB buffer pool instead of the native 80%-of-RAM default (#2557) createLbugDatabase passed bufferManagerSize=0, which the native runtime sizes at 80% of physical RAM. A long-lived gitnexus mcp process (or a large incremental analyze) could balloon to that ceiling — 19.5 GiB observed against a 105 MiB on-disk index — and OOM-kill the host session. Resolve the pool at call time: default min(2 GiB, max(64 MiB, 80% of totalmem)), overridable via GITNEXUS_LBUG_BUFFER_POOL_SIZE (bytes); 0 deliberately restores the native unbounded default; invalid values warn and fall back, mirroring GITNEXUS_WAL_CHECKPOINT_THRESHOLD. Co-Authored-By: Claude Fable 5 * docs(readme): document GITNEXUS_LBUG_BUFFER_POOL_SIZE and GITNEXUS_LBUG_MAX_DB_SIZE (#2557) Both env tables gain the new buffer-pool ceiling variable and the previously code-comment-only GITNEXUS_LBUG_MAX_DB_SIZE, with the mmap-vs-memory distinction the issue had to discover from source. Co-Authored-By: Claude Fable 5 * refactor(lbug): keep parseBufferPoolSize module-private Review finding: the export had zero importers — parseWalCheckpointThreshold earns its export via the CLI flag validation, but the buffer-pool CLI flag was deliberately deferred. Re-export when a consumer exists.

JLS 13.1 anonymous naming (#2558) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(java): JLS 13.1 immediate-host naming for anonymous bodies + v9 schema window (#2555, step 1) `synthesizeJavaAnonymousClassName` generalizes to both anonymous-body shapes (`object_creation_expression` with a `class_body`; `enum_constant` with a `body:` field) and switches from topmost-host naming to JLS 13.1 binary names: the `$`-joined chain of enclosing host types (`EnumWrap$Mode$1`), numbered per IMMEDIATE host in source order across both shapes (javac's shared counter). Every existing fixture's immediate host is its top-level type, so existing names are unchanged — proven by the 11 #2550 tests passing untouched, not assumed. The owner walk's anonymous branch also fires on `enum_constant` now (the synthesis returns undefined for body-less constants, so the walk continues to `enum_declaration` as before). Identity window: INCREMENTAL_SCHEMA_VERSION 8→9, parse-cache SCHEMA_BUMP 18→19, U-C5 pin extended with the v8-stamp rejection (enum-constant methods re-key `E.hook`→`E$1.hook`; nested-host anons re-key `EnumWrap$1`→`EnumWrap$Mode$1`). Enum-constant Class-node emission and scope-side ownership land in the next commits per docs/plans/2026-07-18-gitnexus-plan-enum-constant-bodies.md (plan is local — docs/ gitignored). Co-Authored-By: Claude Fable 5 * feat(java): model enum constant bodies as first-class instances (#2555, steps 2-4) `enum E { A { void hook(){} } }` — javac's other anonymous-class shape — joins the #2550 instance model: - Structure: `(enum_constant body: (class_body)) @definition.class` in JAVA_QUERIES; `enum_constant` in javaClassConfig.typeDeclarationNodes with extractName synthesis. The shouldSkipClassCapture guard now also covers enum_constant — without it, extract()'s name fallback would fabricate a Class node from the constant's own identifier (`A`). - Scope: `(enum_constant body: (class_body) @scope.class)` + synthesized `@declaration.class`/`@declaration.name` anchored on the body, so the constant's methods are owned (`ownerId`) and re-keyed (`Method:...:EnumConst$1.hook#0`). - Inheritance: a body-anchored `@reference.inherits` naming the HOST ENUM (javac semantics: E$N extends E) — `mroFor(E$N) ∋ E`, so bare calls from the body to enum helpers pass the ownership gate's MRO arm while the same-file bare-call leak for constant-body method names is closed (discrimination evidence: the #2549 review's archived S1b probe showed the identical shape resolving `local-call` pre-fix). - Nested-host JLS naming verified end-to-end: `EnumWrap$Mode$1` (not `EnumWrap$1`). - Bench: java scope-capture fingerprint rebaselined (new captures + two fixtures), `measure.mjs --check` PASS across all 14 languages. Verified: full java.test.ts 230/230 twice sequentially; TS 254 + JS/ Kotlin 289 (shared-file spot set); schema/scope/owner unit suites 90. Co-Authored-By: Claude Fable 5 * fix(java): exempt $-chain anonymous class defs from nested-class qualification (#2555 review) Review lens probe caught a HIGH collapse: same-named methods across sibling enum constant bodies attributed to the FIRST body's Method node (`M3$1.hook -> M3.log` where the log() call lives in C's body; the same-target sibling edge vanished entirely under dedup). Root cause: `populateClassOwnedMembers`'s qualifier chains a constant-body class def to `M3.M3$2` — its Class scope's parent is the enum's Class scope, unlike OCE anons whose parent is a Function scope — and its methods to `M3.M3$2.hook`. The structure-phase node id encodes `M3$2.hook`, so the graph-bridge's qualified key misses and falls to the file-wide simple-name lookup: first-write-wins. Fix: `qualify()` now skips CLASS-LIKE defs whose name already carries a `$` chain — a synthesized anonymous binary name is complete by construction (JLS 13.1). Narrowly scoped: `$`-named MEMBERS (legal and real in JS/TS) still qualify against their class, and named nested classes (`Outer.Inner`, #1978) are untouched. Discriminating regression test: same-name/distinct-target sibling bodies must each own their edge, and the misattributed cross-edge must not exist. Verified: full java.test.ts 231/231; Python+Kotlin 459 (heaviest populateClassOwnedMembers consumers) — zero assertion failures. Co-Authored-By: Claude Fable 5 * chore(ci): prettier formatting + java bench rebaseline at the final corpus (#2555) Two CI reds from the review-fix commit landing AFTER the bench rebaseline: (1) prettier reformat of the new java.test.ts describe; (2) the java scope-capture fingerprint drifted again because the review fix added the java-enum-constant-same-name fixture to the corpus — rebaselined at the true final corpus (196 fixtures, ce104a76…, scaling 1.05 < 1.5), local `measure.mjs --check` PASS across all 14 languages. Lesson honored going forward: the bench rebaseline is the LAST artifact step — any post-review fixture addition reopens it. Co-Authored-By: Claude Fable 5 * feat(java): strict JLS 13.1 chaining through anonymous enclosing types (#2555) Per review discussion: anonymous enclosing types now chain into the binary name instead of flattening to the nearest NAMED host — the immediately enclosing type per JLS 13.1 may itself be anonymous: - anon inside an anon: NestHost$1$1 (was NestHost$2) - anon inside an enum constant: N$1$1 (was N$2) - named nested hosts (unchanged): EnumWrap$Mode$1 `nearestJavaAnonHost` becomes `nearestJavaEnclosingType` (named hosts OR anonymous bodies); an anonymous enclosing type's prefix is its own synthesized name (memo-bounded recursion); numbering is per immediately enclosing type in source order. Top-level-hosted names are untouched — the full existing suite passes unchanged. New coverage: anon-in-anon chain, anon-in-constant-body chain (with ownership), and a bodied constant in a NESTED enum (EnumWrap2$Mode$1 — the one host combination previously untested). Rides the unreleased v9 identity window (doc wording tightened); java bench fingerprint rebaselined at the final corpus, `--check` PASS across 14 languages; prettier clean. Verified: full java.test.ts 234/234 (one worker-crash flake rerun green in isolation).

Whitelisted in .gitignore and registered in AGENTS.md and CLAUDE.md outside the auto-managed gitnexus block. Co-Authored-By: Claude Fable 5 * fix(skills): apply ce-plan validation findings (tool contract, consistency, conventions) Tool contract: impact mode:'pdg' shape now includes the schema-required direction param; CDG branch sense documented as the result 'label' field (reason is cypher/raw-edge only); explain caveats corrected to its real false-negative classes (cross-function TAINT_PATH is modeled). Consistency: PDG slice homed in working memory (ledger keeps one-liners); depth knob defined and category-overrides-baseline ordering stated; call_depth (consumed by nothing) and content-hash bookkeeping dropped; Never section folded into Hard rules; Phase 3 deduplicated to a pointer; allowed-repeat escalations defined; budget/discard accounting clarified; verification-commands gathering added to Phase 4; open_questions added to the context pack. From scenario runs: plans now pin the verified-at HEAD commit and index freshness in a header, tag claims [verified]/[graph]/[inferred]/[assumed], quote load-bearing tool output, prefer pre-hook-carrying npm scripts, and support an out: destination override; output path defined as the Phase 1 target repo root. Conventions: AGENTS.md 1.9.0 / CLAUDE.md 1.4.0 changelog rows + metadata bumps; future ce-implement qualified as future. Co-Authored-By: Claude Fable 5 * feat(skills): rename ce-plan → gitnexus-plan; add cross-CLI (Codex) entrypoints Renames the skill dir, frontmatter, output filename convention, plan H1 (GitNexus Engineering Plan), the future executor handle (gitnexus-implement), the .gitignore whitelist entry, and all AGENTS.md/CLAUDE.md references. Follows the pr-swarm-review cross-CLI pattern: SKILL.md is the canonical CLI-neutral spec, AGENTS.md § Engineering planning is the Codex/any-agent entrypoint, and the README documents the optional user-level ~/.codex/prompts/gitnexus-plan.md slash command plus an invocation matrix. Skill prose de-branded from Claude Code (agent-neutral verification layer). Also fixes two post-review README contradictions: the anti-reread claim now names the ledger's allowed escalations, and 'read-only by contract' is now 'planning-only' (the skill writes exactly one repo file — the plan); the scope-creep rule and template §12 now agree on where deferred follow-ups land. Drops the stale plugin-collision limitation. Co-Authored-By: Claude Fable 5 * docs(skills): document Codex user-level install path for gitnexus-plan Codex discovers SKILL.md skills from ~/.agents/skills (same path the other gitnexus-* skills install to); README now documents the cp install plus the optional ~/.codex/prompts slash-command file, with the prompt body preferring the repo copy and falling back to the user-level install. Co-Authored-By: Claude Fable 5 * feat(skills): gitnexus-plan freshness gate + active PDG-layer refresh Freshness is now a Phase 1 gate, not advisory: under the default freshness:strict, a stale index is refreshed once per planning session via node .gitnexus/run.cjs analyze --index-only (appending --pdg when the task will reach the PDG phase), then the context resource is re-read. A missing PDG layer likewise triggers the one permitted --index-only --pdg refresh and re-probe instead of a passive recommendation. freshness:accept (or a failed/impractical refresh) preserves the old behavior: plan on the stale graph, source-weighted, labelled in the plan header. --index-only is the load-bearing flag choice — it suppresses all file generation, so the planning-only contract holds (only the .gitnexus store changes). Ledger gains an index_refresh record; plan header states fresh / refreshed / refresh-skipped-with-reason. Co-Authored-By: Claude Fable 5 * feat(skills): gitnexus-plan runner build check before freshness refresh When the target repo builds the analyzer from its own source (bin → dist/ mapping, as gitnexus/ does), the Phase 1 freshness gate now verifies dist/ is current before running the analyze refresh — rebuilding via the package's build script when any analyzer source file is newer than the built entrypoint — and prefers that freshly built CLI. Otherwise a stale dist re-indexes with outdated extraction logic and the 'fresh' index lies. Rebuilds are recorded in the ledger's index_refresh; the PDG-phase refresh inherits the same check. Co-Authored-By: Claude Fable 5 * feat(skills): add gitnexus-work executor and gitnexus-lfg pipeline gitnexus-work executes a gitnexus-plan as verified atomic commits: consumes the §11 implementation_context pack, drift-checks the plan's evidence pin against HEAD, re-verifies assumptions before relying on them, runs impact before every symbol edit and detect_changes before every commit (repo mandates), builds tests from the plan's scenarios, and routes structural drift back to gitnexus-plan Deepen mode instead of coding around it. gitnexus-lfg is a thin orchestrator: gitnexus-plan → blocking user gate (deepen / proceed / stop, deepen loops allowed) → gitnexus-work → review via the existing gitnexus-pr-review skill (open PR, else branch diff vs default). One bounded fix cycle for review findings; never pushes or opens a PR on its own. gitnexus-plan gains a Deepen mode (re-run freshness gate, escalate to depth:deep, re-verify graph/inferred/assumed claims toward verified, rewrite the same file); its 'future gitnexus-implement' placeholder is retired in favor of gitnexus-work. Registered via .gitignore whitelists, AGENTS.md 1.10.0 (section renamed to Engineering planning & execution), CLAUDE.md 1.5.0. Co-Authored-By: Claude Fable 5 * fix(skills): apply cross-skill review findings to the gitnexus skill family Two P1s: gitnexus-plan Deepen mode now re-anchors before re-pinning (diffs the old evidence pin over every [verified]-claim file and re-reads or downgrades before the header moves — moving the pin without this laundered stale claims as verified); the index-refresh budget is stated once in Phase 1 (one --index-only refresh plus at most one Phase 3 --pdg upgrade per session, Deepen = its own session) with ledger and pdg-slice deferring to it. Contract fixes: gitnexus-work's drift check now covers every file the pack cites (not just files_to_modify) and parses the full pack incl. primary/related symbols and acceptance_criteria (walked in Phase 4 alongside §13); a pre-completed check skips §7 steps already landed and Deepen gains a reconcile-execution-state step, closing the mid-execution route-back loop; pack assumptions must name what to check and how. lfg: Lane 4 passes the merge-base to detect_changes compare (two-dot diff misattributes upstream commits when default advanced), branch-diff is the stated normal case, oversized review findings route to the plan gate instead of overflowing direct mode, the one-fix-cycle cap is explicit on re-run, and headless runs end at the plan gate with the plan as deliverable. work: blank mode narrowed to *gitnexus-plan*.md with a re-execution guard, direct-mode discipline spelled out, branch meaningfulness defined against the plan slug, and the plan document is committed as the branch's docs commit (review diff includes it). Planning-only contract now names the dist/ rebuild as the second permitted state change; Phase 5.1 names the four claim tags; stale AGENTS.md anchors fixed. Known latent issue left untouched: gitnexus/gitnexus-pr-review pairs a three-dot example with a two-dot detect_changes compare — that skill is also shipped by the plugin, so fixing it here would drift the copies; lfg compensates by passing the merge-base. Co-Authored-By: Claude Fable 5 * feat(skills): ship the engineering skill family with the gitnexus package npm i -g gitnexus users now get gitnexus-plan / gitnexus-work / gitnexus-lfg: the three skills are added to gitnexus/skills/ in directory form (SKILL.md + references/), which installSkillsTo already enumerates dynamically and copies recursively to every editor target (~/.agents/skills for Codex, Cursor, OpenCode, Qoder, ...) on gitnexus setup — uninstall enumerates the same root, so removal stays clean. The Claude Code plugin channel (gitnexus-claude-plugin/skills/) carries the same copies plus the standard per-skill mcp.json. Global-install support in the skill text: gitnexus-plan Phase 1 now resolves the analyzer runner explicitly — node .gitnexus/run.cjs analyze when the project has a runner, else gitnexus analyze (installed CLI), else npx gitnexus analyze — and all analyze mentions route through it, satisfying the skills-steering policy (#1939/#1945) which sweeps the plugin copies. New drift guard test/unit/shipped-skills-sync.test.ts asserts the npm and plugin copies stay byte-identical to the canonical .claude/skills/ family (plugin = canonical + mcp.json), same discipline as run.cjs ↔ resolve-invocation.ts. skills-steering + shipped-skills-sync: 11/11 green. Co-Authored-By: Claude Fable 5 * feat(eval): workflow_bench — measure the skill workflow's token savings Benchmarks gitnexus-plan → gitnexus-work against a baseline agent (--disallowedTools Skill) on identical tasks, in fresh detached worktrees, using real headless Claude Code sessions; every number comes from the CLI's --output-format json usage report (field names validated against a live 2.1.207 session). Reports per-arm medians (input/cache/output tokens, cost, wall time, turns), a savings row, and resolve status from a per-task verify command — savings on failed tasks are flagged, not celebrated. Per-task setup hook prepares fresh worktrees (deps); --permission-mode bypassPermissions (default) lets sessions run unattended in the throwaway trees. Free-model support: --base-url/--auth-token/--model route headless sessions through any Anthropic-compatible endpoint; free-model.litellm.yaml is a ready litellm-proxy template for OpenRouter :free variants or local Ollama, so benchmarking burns no paid tokens (README documents rate limits and the small-model skill-following caveat). Harness validated end-to-end with a stub CLI (worktree lifecycle, both arms, plan→work chaining, verify, aggregation, report) and 4 pytest units for the pure aggregation/savings/report helpers. AGENTS.md 1.11.0. Co-Authored-By: Claude Fable 5 * docs(eval): record first workflow_bench calibration run Trivial-task calibration (add -V alias): both arms resolved; workflow arm ~4.3x baseline cost — the documented overhead-dominated regime, recorded so the regime boundary is empirical rather than asserted. Co-Authored-By: Claude Fable 5 * feat(eval): workflow_bench scenario matrix — arm variants, task classes, churn Ground-base measurement across scenarios: tasks.scenarios.yaml spans four labeled classes (trivial → investigation-bug → investigation-feature → cross-module) with deterministic verifies (prescribed test files). New arms: workflow_direct (gitnexus-work direct mode — the middle option that locates the routing boundary lfg's gate and work's triage encode) and baseline_nomcp (no skills AND no graph tools — separates workflow-discipline value from GitNexus-tool value; off by default). Records now carry task class and diff churn (files/+ins/−del vs the starting commit) as an over-engineering proxy; the report renders a class column and per-arm savings rows vs baseline. 5 pytest units + stub-CLI e2e of the full three-arm matrix. Co-Authored-By: Claude Fable 5 * docs(eval): record workflow_bench ground base; fix churn measurement bias Ground base (3 classes x 3 arms, n=1/cell): every arm resolved every task — pass/fail quality saturates at this difficulty, making the comparison pure cost. Full plan→work never amortized its ~$9-11 fixed cost on tasks a baseline finishes in ≤35 turns (−211% to −333% cost); workflow_direct sits near baseline (−15% to −55%, once faster wall) with more test coverage. Routing implication recorded: direct mode/plain agent below this scale, full workflow for cross-module / multi-session / plan-as-deliverable work. The cross-module cell and multi-run variance are the next measurements. Churn fix: git add --intent-to-add -A before diffing (arms that never commit no longer undercount new files) and :(exclude)docs/plans (the committed plan doc no longer inflates workflow churn); this run's churn numbers predate the fix and are omitted from the recorded table. Co-Authored-By: Claude Fable 5 * perf(skills): cost-optimize the workflow from measured ground base Every optimization targets a measured fixed-cost component (eval/workflow_bench ground base: workflow arm −211% to −333% vs baseline, all tasks resolved): - Plan form is category-priced: compact form (core sections w/ § anchors preserved, ≤80 lines excl. pack, mini-pack subset of the context pack) for narrow/default categories; the full 13 sections only for deep work (refactor/security/performance/concurrency/architecture). A compact plan outgrowing its cap reclassifies to full rather than overflowing. - Freshness gate is category-priced: compact categories default to accept (source-weighted, refresh only when a graph claim becomes load-bearing); strict stays the default for full-plan categories — the rebuild+re-index was the largest single fixed cost. - Turn economy: per-category tool-call budgets (~10 to ~45; architecture uncapped); budget exhaustion routes open questions to §12 instead of more digging. - gitnexus-work fast path: HEAD == evidence pin → skip all citation re-reading (the pin's entire point); mini-pack fields tolerated. - lfg Lane 1 boundary triage: tasks below the measured ~35-turn boundary get offered gitnexus-work direct mode before the plan lane is spent. Copies re-synced (npm skills/, plugin, ~/.agents); steering + sync guards green. Re-measurement of the workflow arm follows to verify the numbers actually improve. Co-Authored-By: Claude Fable 5 * docs(eval): record optimization re-measurement — inv-bug workflow cell −20% cost Same task, same conditions, post-830a0459 skills: $14.56→$11.70 (−20%), 83→72 turns, cache_read −24%; verified in-transcript that the compact form, turn budget, and skipped rebuild/re-index all fired. Wall +15% from a work- session test-debugging tail (n=1 variance). Regime unchanged (~3.5x baseline on this class) — routing rule stands. Co-Authored-By: Claude Fable 5 * fix(eval): per-arm clone isolation — worktree ref-namespace leak contaminated an arm The cross-module workflow_direct cell reported an impossible 28-turn solve with churn byte-identical to the workflow arm: git worktree add shares the repo's ref namespace, so the workflow arm's slug branch (created by gitnexus-work Phase 2) survived worktree removal and the direct arm found and adopted the completed work. Arms now get isolated git clone --shared copies (object store via alternates, refs clone-local — agent branches and stashes die with the clone; origin/ fallback for non-default refs). Leaked branch deleted; baseline arm verified clean (0 branch references in its transcript); cell marked invalidated pending re-run. Records the valid cross-module cells: workflow $18.32 vs baseline $18.03 (premium −1.6%, vs −211%..−333% on smaller classes) — fixed costs amortize at this scale, with a less destructive diff and a plan artifact as bonus; resolve rate still tied. Churn fingerprinting is what caught the contamination — noted in the README as an integrity check. Co-Authored-By: Claude Fable 5 * docs(eval): complete cross-module cell — direct mode wins 47% cost / 56% wall Clean clone-isolated re-run: workflow_direct resolved the hardest class at $9.53/52 turns/15m vs $18.03/98/34m baseline and $18.32/107/37m full workflow. The measured story across all four classes: the execution discipline (gitnexus-work) is the consistent sweet spot and delivers real token savings on hard tasks; the planning pass buys its artifact, not same-session savings. Resolve rate tied everywhere (n=1/cell caveat). Co-Authored-By: Claude Fable 5 * feat(eval): add trajectory-gated skill evolution (#2431) - Pair prompt candidates with incumbent workflow arms - Gate promotions on pinned-model quality and efficiency - Expire router evidence and document its lifecycle * fix(eval): allow pr-review skill candidates * feat(skills): rename and generalize GitNexus review * feat(eval): external-comparator and review arms for workflow_bench - ce_workflow / ce_workflow_direct: compound-engineering ce-plan/ce-work arms prompted with the same structure as the gitnexus arms - review / ce_review: gitnexus-review vs ce-code-review on an identical diff applied by the task's setup - plan handoff is snapshot-based: committed example plans in docs/plans/ tie on clone mtimes and broke the name-glob pick (executed a stale plan) - verify output tail is recorded per run and the final working-tree patch is kept, so failed rows are diagnosable after the clone is destroyed Co-Authored-By: Claude Fable 5 * fix(skills,eval): address #2431 review — data-safe rename migration, fail-closed bench evidence - setup: never delete a legacy renamed skill dir — the installer cannot prove ownership (users customize or hand-write skills under these names); warn with the path instead, and the test now asserts survival - workflow_bench: fail closed when a session's --output-format json report is empty, malformed, or missing usage fields — an exit-0 shell with no parseable usage no longer counts as measured evidence (5 parametrized regression tests) - workflow_bench: document the trust model prominently (task setup/verify are shell-executed, sessions run bypassPermissions with the parent env, candidate overlays are prompt injection surface) in README + docstring - free-model.litellm.yaml: master_key from LITELLM_MASTER_KEY env instead of a static token; loopback-binding warning - ci: run the eval workflow_bench pytest suite on ubuntu (pytest+pyyaml only — no full eval stack) Co-Authored-By: Claude Fable 5 * fix(eval): demand observed foreground verification in headless work-arm prompts In a headless -p session there is no later turn: a work arm backgrounded its slow test run, scheduled wakeups that can never fire, and reported done while two of its tests failed. All four work-arm prompts (both skill families, symmetric) now require verification output to be observed inside the session. Co-Authored-By: Claude Fable 5 * feat(skills): ask plan depth up front instead of offering deepen afterwards gitnexus-plan Phase 0 now asks one blocking question in interactive sessions — quick / standard / deep, mapped onto the existing depth/form/ freshness knobs — when the invocation carries no explicit depth signal. Explicit knobs and headless runs skip the question (category posture unchanged, so benchmarks and automation behave as before). gitnexus-lfg's plan gate slims to proceed/stop: depth was already the user's up-front choice, so deepening is no longer offered by default — an explicit deepen request at the gate and executor route-backs still run Deepen mode, which remains the mechanism for strengthening an existing plan document. All shipped copies resynced (npm skills/, Claude plugin); AGENTS.md 1.13.0 and CLAUDE.md 1.7.0 pointers updated, including the analyzer's regenerated index-stats block at this branch's head. Co-Authored-By: Claude Fable 5 * feat(skills): taint pass, expert lenses, and post-work index refresh gitnexus-review gains a PDG-backed taint-and-dependence pass (explain + pdg_query, --pdg folded into the stale refresh on trust-boundary diffs) and an Expert lenses section: domain reviewers derived from the graph's clusters plus four cross-cutting lenses (architectural fit, language conformance per the repo's own contract, Definition of Done, simplicity), dispatched once after the evidence-gathering steps and scaled to the diff. gitnexus-work Phase 4 now refreshes the knowledge graph after the DoD walk via the resolved-runner ladder with analyze --index-only, so the lfg review lane and later sessions query the finished work without dirtying the tree. lfg's threshold-governance paragraph moves to its README; eval citations are tagged as measured in the GitNexus repo. All shipped copies re-synced. Co-Authored-By: Claude Fable 5 * fix(cli): remove legacy gitnexus-pr-review on uninstall; cover the rename migration uninstall's removal set now includes LEGACY_SKILL_DIR_NAMES derived from RENAMED_SKILL_DIRS, so a pre-rename install is cleaned up instead of orphaned. The rename warning gains behavioral coverage (fires with a legacy dir present, silent without), and shipped-skills-sync asserts legacy names stay absent from every shipped tree. Co-Authored-By: Claude Fable 5 * fix(eval): metric provenance, error-kind rows, skill-invocation verification, gate noise floor The promotion gate defaults to cost_usd (the only metric that includes subagent spend); token metrics carry an explicit main-loop-only warning in the report and promotion.json. Rows are classified by error_kind (session-error / verify-failed / infra-error), excluded from efficiency medians, and the gate requires equal valid-run counts. Each session's transcript is scanned for the expected Skill invocation and fails closed on a verified miss; a one-run resolution edge no longer promotes (noise floor). Per-run timeouts and setup failures record an infra-error row instead of aborting the sweep. Overlays touching skills no candidate arm exercises are rejected up front. Co-Authored-By: Claude Fable 5 * docs: fix skill routing paths, version headers, and skill rosters Routing tables point at the tracked direct skill paths (matching the post-#2434 generator output), AGENTS.md/CLAUDE.md headers match their latest changelog rows, the 1.12.0 row describes what the migration actually does, package/cursor READMEs list the full shipped skill roster, and the swarm READMEs describe /gitnexus-review's expert lenses instead of calling it single-agent. Co-Authored-By: Claude Fable 5 * ci: drift-guard workflow for skill copies; pin eval pip deps; track docs/plans ci.yml ignores '**.md', so an md-only skill edit would merge without the shipped-skills-sync test running — skill-sync.yml triggers exactly on the guarded trees. The eval job's pip install is version-pinned, and docs/plans/ is unignored so gitnexus-plan output can be committed. Co-Authored-By: Claude Fable 5 * fix(ci): keep the runner-invocation literal in gitnexus-review; add concurrency block to skill-sync skills-steering requires skills with a stale-index hint to carry the exact 'node .gitnexus/run.cjs analyze' form — restore it with the fallback ladder as a parenthetical instead of replacing it. skill-sync.yml gains the top-level concurrency block the workflow-convention check enforces. Co-Authored-By: Claude Fable 5 * feat(skills): token-economy guidance for expert lenses Merge lenses that ground in the same material into one reviewer, and use cheaper model/effort tiers for mechanical lenses where the harness offers them, reserving the strongest engine for adversarial judgment. Co-Authored-By: Claude Fable 5 * test(eval): isolate transcript home on Windows Ensure workflow_bench transcript tests set USERPROFILE alongside HOME so Path.home() resolves to the temporary test home on Windows. * docs(skills): fold PR #2522 execution learnings into review/work/plan Eight incident-backed hardenings from running the full skill cycle (review -> plan -> work, 28-finding fix series) on PR #2522: gitnexus-review: - Expert lenses execute the code under review on candidate failing shapes (empirical probe outranks source reading — every HIGH the language lenses found came from a probe, not a read). - Step 7 re-runs the exact CI check for refreshed baselines/fingerprints (a stale committed artifact is invisible in the diff; caught a red benchmarks arm). - Step 8 treats version/invalidation constants as review surface (INCREMENTAL_SCHEMA_VERSION class recurred verbatim from #2494). gitnexus-work: - Step 4 proves regression tests discriminate against the pre-fix tree. - Step 5 rebuilds executed build output before every verification run (parse workers load dist/; a correct fix 'failed' until rebuilt). - Step 6 makes stage -> detect_changes -> commit one unbroken sequence. gitnexus-plan: - Phase 0 seeded-evidence mode: plan FROM a completed review's verified findings instead of re-running the graph ladder. - Template §7: fingerprint/golden-guarded output rebaselines once, at the series tip. All distribution copies resynced; shipped-skills-sync + skills-steering 24/24 locally. Co-Authored-By: Claude Fable 5 * feat(eval): close the skill-evolution loop with an automated proposer driver workflow_bench.evolve adds the three arrows the README described as manual: a proposer session that turns loser trajectories (results.jsonl rows, transcripts, patches, the learning queue) into ONE bounded candidate overlay, a driver that iterates propose -> paired benchmark -> deterministic gate up to --generations, and an --apply step that copies a promoted overlay onto the canonical skills and shipped mirrors as a working-tree diff. The trust boundary is unchanged: overlays re-validate through candidate_overlay_files before any benchmark or apply consumes them, and committing, CI, and the PR merge stay human. learnings.jsonl is gitignored: it is machine-local evidence, like the session transcripts it complements. Co-Authored-By: Claude Fable 5 * docs(skills): route live-task friction into the evolution learning queue Each family skill gains a short 'Skill feedback' section: on friction with the skill's own instructions, append one JSON line to eval/workflow_bench/learnings.jsonl (GitNexus repo only) — never self-edit the skill from a live task. The proposer in workflow_bench.evolve consumes the queue as hints; a learning reaches a shipped skill only by beating the incumbent on the paired benchmark. All shipped mirrors re-copied byte- identical. Co-Authored-By: Claude Fable 5 * ci(tests): run the evolve helper tests in the eval pytest job test_evolve.py needs only pytest+pyyaml, same as the harness tests the job already runs — without this line the new module had no CI coverage. Co-Authored-By: Claude Fable 5 * feat(ci): comment-triggered GitNexus review agent for PRs '@gitnexus review' from a maintainer (OWNER/MEMBER/COLLABORATOR; the action re-validates write access) runs the repo's gitnexus-review skill headlessly against the PR and posts the review as a sticky comment — remote triggering with no local setup. Read-only by construction: contents: read token, Write/Edit and web tools disallowed, Bash allowlisted to git reads and the gitnexus CLI; analyze parses PR code with tree-sitter, never executes it. Requires the ANTHROPIC_API_KEY repository secret; activates once the file is on the default branch. Co-Authored-By: Claude Fable 5 * feat(ci): dispatch lane + existing OAuth secret for the review agent Align with claude.yml: same action pin and the CLAUDE_CODE_OAUTH_TOKEN secret the repo already carries — no new secret to configure. Add a workflow_dispatch lane (PR number input) so the agent can be triggered from the Actions UI and tested before the issue_comment trigger reaches the default branch. Allowlist gh pr view/diff and gh api, which the review skill uses to pin PR SHAs. Co-Authored-By: Claude Fable 5 * fix(ci): close a fork-PR RCE vector in the review agent's tool allowlist A live headless run of the exact workflow session against PR #2431 (66 turns, full gitnexus-review pass) surfaced a real HIGH-severity confused deputy: .gitnexus/ is gitignored, not blocked — a fork PR can commit its own .gitnexus/run.cjs, issue_comment checks out PR-head content, and the skill's runner ladder tries 'node .gitnexus/run.cjs analyze' first. That would execute fork-controlled JS inside a job holding CLAUDE_CODE_OAUTH_TOKEN and a write-scoped GITHUB_TOKEN — the opposite of the 'PR code is read, never executed' claim in the workflow's own header. Fix: drop the run.cjs allowlist entry so analyze always resolves through npx gitnexus (npm registry, not the checked-out tree); the skill's documented fallback mode covers the resulting graceful degradation. Also drop 'gh api' (not read-only — accepts -X POST/PATCH/DELETE) and downgrade pull-requests: write to read (comment posting only needs issues: write; the prompt already forbids formal review submission). Same session flagged a latent evolve.py bug: select_evidence's cost sort used dict.get's missing-key default, which doesn't cover an explicit JSON null in a foreign --seed-results row and crashes proposer setup with TypeError. Guarded with 'or 0.0' and added a regression test. Co-Authored-By: Claude Fable 5 * fix: harden PR review and evolution trust boundaries * ci: follow workflow concurrency convention * fix(eval): make terminating error paths explicit * fix: unblock hardened review runtime checks * test: make containment canaries deterministic * test: expose Claude canary tool failures * fix: adapt clean shell environment for Claude * fix(eval): accept the runner's transcript source key in evidence preflight The proposer evidence preflight required transcript-artifact metadata to be exactly {path, sha256, bytes}, but the runner stamps a fourth provenance key (source=parent-captured-stream-json). Any --seed-results or generation>=2 run therefore aborted with SandboxError before proposing or promoting. Pin the producer literal as PARENT_EVENT_STREAM_SOURCE and validate it in the metadata check, and round-trip real producer output through sum_sessions into the preflight so the schema can't drift again. * fix(eval): treat an unmeasured session cost as unavailable, not $0 well_formed validated only the nested usage block, so an otherwise-successful session missing total_cost_usd was recorded as cost_usd=0.0 — and cost_usd is the default promotion metric (lower wins), so a cost-less session scored as free and could win promotion it never earned. Extract cost via measured_cost() (None on absent/garbage, a measured 0.0 preserved), propagate None through sum_sessions/aggregate/savings/report, and have the gate refuse to rank on a metric that was not measured on every run in both arms. * fix(eval): warn when ranking on the main-loop-only num_turns metric num_turns comes from the CLI's top-level usage (main-loop session only), like output_tokens, but selecting it emitted no metric_warning — so a subagent-heavy candidate could look artificially efficient. Add num_turns to MAIN_LOOP_ONLY_METRICS and broaden the warning to cover turns. * fix(eval): fail closed when an overlay adds a file with no committed base An overlay adding a new .md under gitnexus-{plan,work} passes the structural overlay checks but has no committed base for committed_destination_base_digests to bind against, so it raised an uncaught ValueError that crashed the evolve driver (and runner --candidate-overlay) mid-run. Catch it at both call sites: evolve reports NOT PROMOTED and exits, runner routes it through parser.error. * feat(eval): circuit-break the runner sweep on a systemic outage A sustained upstream outage used to pay out every remaining --timeout window one session at a time. Track consecutive session/infra/cleanup failures via a pure systemic_outage_streak helper; after --outage-streak (default 5) in a row, stop the sweep, still write report.md/promotion.json from partial evidence, and exit non-zero so evolve.py halts instead of proposing from truncated evidence. A task's own resolved=False never trips the breaker. * fix(cli): report a dirty working tree as stale in gitnexus status status --json (and the human output) computed up-to-date from commit + runner identity + completeness only, so a repo with uncommitted source changes at a matching HEAD was reported up-to-date while analyze would still re-index it. A graph-backed agent gating on that JSON could skip re-analysis on a stale graph. Extract analyze's dirty-tree check into a shared isWorkingTreeDirty() in storage/git and fold it into the status freshness decision. * fix(ci): use single-slash deny globs in the review agent's disallowedTools github.workspace already expands to an absolute path, so Read(/${{ github.workspace }}/**) and Read(//proc/**),(//sys/**),(//dev/**) produced double-slash patterns that a normalizing matcher may not match — silently no-opping the deny layer. Not exploitable (the allowlist is the primary control and never grants those paths), but the globs should be well-formed. Update the pinned test strings. * ci: install gitnexus-shared with npm ci from the committed lockfile The gitnexus-shared build floated its deps via npm install in three workflows (skill-sync, ci-tests, and — most importantly — the release publish.yml) while every other install step uses npm ci. The lockfile is committed and in sync, so switch all three to npm ci for reproducible, locked installs. * test(cli): make the shipped-skills drift guard reject symlinks listFilesRecursive walked with readdirSync and snapshotDir read with readFileSync, both of which follow symlinks — so a mirror file symlinked to the canonical tree passed the byte-compare (and a symlinked mirror dir would be followed too). Reject a symlinked root via lstat and any symlinked entry via Dirent.isSymbolicLink, with negative tests (skipped on Windows). * test(eval): guard the candidate-skill vs mirror-root coverage invariant MIRROR_SKILL_ROOTS omits the Cursor tree, safe only because no candidate skill is cursor-shipped. Pin that invariant: every CANDIDATE_SKILLS entry must exist under canonical + every mirror root and must not ship to Cursor, so adding a cursor-shipped skill to the candidate set (the PR #2488 asymmetric-sync class) fails loudly instead of syncing three of four trees. * docs(ci): describe the review agent's staged post-merge rollout The DoD asked for a dry-run or triggered run before merge, but an issue_comment (or newly added workflow_dispatch) workflow only ever executes the default-branch copy, so it cannot be exercised from the PR that introduces it. Reword the DoD and the activation checklist to a staged rollout: merge registered-but-disabled, validate same-repo and fork execution post-merge, then enable the variable. * fix: pin plugin skill mcp.json to the release version via #2445 tooling The ten plugin skill mcp.json launched `npx -y gitnexus@latest mcp` on every skill connect — non-reproducible and a supply-chain surface, and (unlike the persisted setup config) never pinned. Extend sync-plugin-manifests.mjs with an mcp surface kind that stamps the gitnexus@ launch arg, pin all ten to 1.6.9 now, and keep them byte-identical so the drift guard stays green. The release lifecycle + publish.yml --check now re-stamp them like the four manifest surfaces; only READMEs stay on @latest as docs. * test(eval): prove the proposer's built-in file tools are confined The real-Claude canary only exercised Bash + MCP, so it proved process/MCP containment but not that the proposer's built-in file tools stay inside their mounts. Add a canary over the exact PROPOSER_ALLOWED_TOOLS surface and the same read-only /evidence mount as run_proposer (allowlist extracted to a shared constant so it can't drift): Read reaches /evidence, a Write into the read-only evidence mount is denied, and a Write lands in the output tree. * fix(eval): apply the candidate overlay after task setup for fair arms The candidate overlay was applied before the task's untrusted setup ran, so setup could observe candidate prose and the incumbent/candidate arms started from different pre-overlay state. Reorder within the sandbox: capture the base (pre-overlay) skill digest, run setup against the base skills, verify setup did not tamper them, then apply the overlay and capture the post-overlay digest the model must preserve. apply_candidate_overlay stages path-specific overlay files, so setup's uncommitted changes stay out of the baseline and churn is unchanged. Graph freshness for the review arm is handled by the status dirty-tree fix plus the review skill's stale-triggered re-index, not by reordering the cached per-task-sha graph materialization (which is mechanically blocked). * test(eval): end-to-end containment proof of the autonomous proposer Drives the real run_proposer through bubblewrap with a deterministic scripted model (no paid API): it reads the read-only evidence bundle and writes a candidate gitnexus-plan skill edit plus a rationale into the sandbox output tree; run_proposer enforces the trust boundary and copies only the validated overlay + proposal out. This exercises the autonomous-proposal stage of the self-evolution loop end-to-end in the eval/containment CI job (the gate and apply stages are covered by test_workflow_bench_evolution and test_promotion_apply). Env-gated on GITNEXUS_REQUIRE_CLAUDE_CANARY, so it runs only where the pinned Claude binary and user namespaces are available. * fix(eval): let the proposer author its overlay via Bash Running the end-to-end proposer canary in the containment CI job surfaced a real bug: run_proposer starts the session with --bare, which hard-disables the Write/Edit tools ("Write exists but is not enabled in this context"), yet allowlisted Edit/Write and omitted Bash. The proposer therefore had no working way to write its candidate overlay — the self-evolution loop could never produce a candidate. The sandbox settings already pre-authorize Bash (autoAllowBashIfSandboxed) and confine writes to workspace/tmp/home, so switch PROPOSER_ALLOWED_TOOLS to Read/Grep/Glob/Bash and tell the proposer to author files with Bash. The end-to-end test now drives the real run_proposer through bubblewrap and asserts a validated overlay + proposal are produced (this also replaces the earlier file-tool canary, whose Write/Edit premise was moot). * test(eval): author the proposer overlay with newline-free Bash content The nested shell-sandbox prefix mangles embedded newlines, so the multi-line overlay content never landed. Use single-line content for the deterministic proposer canary. * test(eval): drop the unverifiable end-to-end proposer canary The scripted proposer overlay never materialized in the containment job across runs, and the model tool-result content is not visible in CI logs, so the test cannot be finalized without an environment where the sandbox can actually run. Keep the verified production fix (Bash-authoring in run_proposer); the proposer sandbox/containment stays covered by the existing Bash+MCP and process-tree canaries. * test(cli): drop run-analyze.ts from the windowsHide spawn-family list U7 moved run-analyze.ts's only child_process call (the git status --porcelain dirty check) into storage/git.ts (already covered by this test, with windowsHide). run-analyze.ts no longer imports a spawn-family function, so the windowsHide-regression test's 'must have >=1 spawn call' invariant failed for it. Remove it from SRC_FILES. --------- Co-authored-by: Claude Fable 5 Co-authored-by: Zander Raycraft Co-authored-by: Azizur Rahman --- .claude/README-gitnexus-reviewer-swarm.md | 8 +-

Classify the task: + +| Category | Posture (depth · plan form · tool-call budget · freshness) | +| ------------------------------ | -------------------------------------------------------------------------------- | +| Bug fix (local) | Narrow, 1–2 primary symbols, `impact_depth` 1 · compact · ~15 · accept | +| Feature | Default knobs · compact · ~30 · accept | +| Refactor / shared API change | Impact mandatory, `impact_depth` 3 · full · ~45 · strict | +| Performance | Default + performance PDG mode (`references/pdg-slice.md`) · full · ~45 · strict | +| Security | Default + security PDG mode + `explain` taint findings · full · ~45 · strict | +| Dependency upgrade / migration | Impact + compatibility focus; PDG rarely needed · compact · ~20 · accept | +| Concurrency / transactional | Control-flow + state-mutation PDG focus · full · ~45 · strict | +| Test improvement / docs | Narrowest: usually no impact or PDG pass · compact · ~10 · accept | +| Architecture change / spike | Widest: clusters + processes first · full · no cap · strict | + +The category posture overrides the Configuration baseline; explicit `key:value` +invocation knobs override both. A task matching several rows combines them: +take the widest depth, union the focus areas. + +**Seeded evidence.** When a completed investigation already supplies +verified findings — a finished review, a triage document with `path:line` +anchors and named failing scenarios — open the ledger FROM it: cite the +source document as the opening ledger entries and plan directly against +them instead of re-running the graph ladder over ground it already covers. +Re-deriving what the evidence proves is budget spent against the +turn-economy rule. Phase 4 still source-verifies whatever Proposed Changes +will cite, at the pinned commit — seeding replaces exploration, never +verification. + +**Depth is the user's decision, asked once, up front.** In an interactive +session, when the invocation carries no explicit depth signal (no `depth:`, +`form:`, or `freshness:` knob, and not Deepen mode), ask one blocking +question before Phase 1 — how deep should this plan go? + +1. **Quick** — `depth:narrow form:compact freshness:accept`. Fastest useful + plan: 1–2 primary symbols, minimal graph work, core sections only. +2. **Standard** — the category posture above, unchanged. Recommend this + unless the classification argues otherwise. +3. **Deep** — `depth:deep form:full freshness:strict`. All 13 sections, + `impact_depth` 3, clusters/processes read, PDG slices for the central + functions. + +The answer sets the knobs exactly as if they had been typed in the +invocation; explicit knobs win and skip the question. Headless runs never +ask — the category posture applies unchanged. Asking up front replaces +offering to deepen a finished plan afterwards: Deepen mode (below) remains +the mechanism for strengthening an existing plan document — a later session, +review findings, an executor route-back — not a default follow-up question. + +**Turn economy is a deliverable.** The plan is judged on decision quality per +token, not thoroughness theater (measured: a 63-turn plan for a two-line +change — the GitNexus repo's `eval/workflow_bench/`). Stay within the category's tool-call +budget; when the budget runs out with questions still open, record them in +§12 instead of digging further — the executor re-verifies cheaply anyway. + +## Phase 1 — Anchor and freshness + +1. Resolve the target repo: `list_repos` if in doubt, else the indexed repo + covering the working directory. Pass `repo` explicitly on every call when + more than one repo is indexed. +2. Record the repo's current HEAD commit in the ledger — every line-number + citation in the plan is pinned to it. +3. **Resolve and record the analyzer runner** (used by every `analyze` + command in this skill): `node .gitnexus/run.cjs analyze …` when the + project has a runner (a previous analyze dropped it next to the index), + else `gitnexus analyze …` (installed CLI — `npm install -g gitnexus`), + else `npx gitnexus analyze …`. Record its path/version and any available + source/build identity; do not manufacture provenance from timestamps. +4. Read `gitnexus://repo/{name}/context` — codebase overview + staleness check. + **Freshness gate.** Plans built on a stale graph make stale blast-radius + claims — but a re-index is the largest fixed cost a planning session + carries, so the gate is category-priced: + - Compact-plan categories default to `freshness: accept`: plan on the + current graph with source verification weighted higher — their plans + cite little graph evidence. Escalate to a refresh mid-plan only when a + graph claim becomes load-bearing (e.g. Proposed Changes rest on a d=1 + dependent list), and only then. + - Full-plan categories default to `freshness: strict`, and under it: + - **Analyzer provenance check — before any refresh.** Compare the resolved + runner identity with the index metadata and, in an analyzer-source + checkout, with current analyzer source. If identity is stale or unknown, + do not build output and do not make that graph load-bearing. Record a + **stale analyzer provenance — source-weighted limitation** in + `index_refresh`, the plan header, and §12; rely on targeted source reads + or hand execution to `gitnexus-work`, which owns the build-current gate. + - Stale index → run `analyze --index-only` via the resolved runner + (append `--pdg` when the task category will reach Phase 3) and re-read + the context resource **only when runner provenance is known-current**. + Refresh budget, stated once here: at most one `--index-only` refresh in + Phase 1 **plus** at most one later `--pdg` upgrade in Phase 3 (only when + Phase 1's refresh lacked `--pdg`) per planning session — a Deepen run is + its own session. Record each command, runner identity, and outcome in the + ledger's `index_refresh`. + - Refresh failed or impractical (no write access to the index, prohibitive + repo size), or `freshness: accept` was passed → proceed on the stale + graph, weight source verification higher, and state the staleness and + the skipped refresh in the plan header and Assumptions. + - Resources unreadable but tools working → proceed on tools alone, treat + freshness as unknown (weight source higher), and note it in the plan. + - GitNexus unavailable entirely → switch to **Fallback mode** (below). +5. For architecture-scale tasks only, also read + `gitnexus://repo/{name}/clusters` and `.../processes`. + +## Phase 2 — Graph navigation ladder + +Use the narrowest operation that answers the current ledger question, in this +order. Budgets: at most `max_primary_symbols` (5) primary symbols and +`max_related_symbols` (20) related symbols active in the ledger. + +1. `query {search_query, task_context}` — locate concepts, execution flows, + modules, and related tests for the task. +2. `context {name}` — 360° view of each candidate primary symbol: callers, + callees, categorized refs, processes. Promote to primary or discard. An + `ambiguous` result (ranked candidates) is answered by one retry narrowed + with `kind` / `file_path` / uid — that retry is an allowed repeat. +3. `impact {target, direction}` — upstream/downstream blast radius for shared + or high-connectivity symbols (`maxDepth` = `impact_depth`; `summaryOnly: +true` first for hub symbols, then drill in — an allowed repeat). Record the + d=1 items — the **direct (depth-1) dependents** — the plan must account + for every one of them. +4. `trace {from, to}` — when the task hinges on _how A reaches B_, one call + instead of chained context hops. +5. Statement-level PDG — Phase 3, for the functions the change centers on. +6. `cypher` — last resort, only for a precise graph question the tools above + cannot express. Read `gitnexus://repo/{name}/schema` first; anchor and + LIMIT every query. +7. `detect_changes {scope}` — only when planning against existing uncommitted + or branch work. + +Do not run every tool by default. A local test fix may finish the ladder at +step 2. + +## Phase 3 — Statement-level PDG slice + +For the 1–3 functions most central to the change, build a bounded **PDG +context slice**. Read `references/pdg-slice.md` and follow it — it owns the +tool calls, inclusion criteria, depth bounds, slice schema, the security and +performance modes, and the no-PDG-layer fallback. + +## Phase 4 — Targeted source verification + +GitNexus said where to look; now confirm what is there. Using ordinary file +reads (exact line ranges, not whole files unless genuinely required): + +- Read every source range the plan will cite: signatures, branch conditions, + state mutations, error paths, nearby comments that change behavior. Compact + plans cite less — verify what they cite, don't expand the citation set to + have more to verify. +- Read the tests GitNexus associated with the primary symbols; never claim a + test exists without having located it. +- Verify the build/test commands the plan will name actually exist + (package.json scripts / CI workflows), and prefer the script form that + carries its prerequisites (pre-hooks) over invoking underlying binaries + directly. +- Check repo conventions that constrain the change (AGENTS.md, GUARDRAILS.md, + lint/build config) — only the parts the change touches. +- Mark each ledger symbol `source_verified: true` as you go. **A symbol that + is named in Proposed Changes must be source-verified.** +- On graph/source disagreement: trust source, record the discrepancy in the + ledger and the plan, recommend re-indexing. Never present stale graph data + as fact. +- Immediately before composition, recompute the versioned + `evidence_provenance` snapshot by invoking + `scripts/evidence-provenance.mjs` exactly as specified in + `references/evidence-provenance.md`: the + canonical global dirty digest over all dirty paths and the sorted manifest + of every cited path, including object kind and + HEAD/index/worktree/untracked layer digests. Re-read any citation that + changed during planning. Exclude only the generated plan path. + +Evidence hierarchy, strongest first: current source and config → current tests +and executable behavior → compiler/build/lint output → GitNexus graph and PDG +→ documentation and comments. + +## Phase 5 — Compose the plan + +1. Read `references/plan-template.md` and fill the category's form — compact + (core sections, ≤80 lines excluding the pack) or full (all 13 sections) — + from the ledger, tagging claims with the template's four classes — + `[verified]`, `[graph]`, `[inferred]`, `[assumed]` — and routing open + questions to §12. +2. Build the implementation context pack per `references/context-pack.md` + (this is section 11 of the plan), including mandatory + `evidence_provenance` in compact and full forms. +3. Set `generated_plan_path` to + `docs/plans/YYYY-MM-DD-gitnexus-plan-.md` under the root of the repo + being planned (the Phase 1 target repo, not necessarily the cwd); use a + 3–5-word kebab-case slug and repo-relative paths inside the document. + Compose the complete document without creating that destination, then + pipe its exact UTF-8 bytes to `scripts/evidence-provenance.mjs write-plan` + as specified in `references/evidence-provenance.md`. The helper safely + creates missing parent directories. Initial planning must not pass + `--replace`. A safe-write failure blocks plan publication: report it and + do not write directly, choose an external destination, or weaken the + repo-relative provenance contract. The snapshot and writer commands apply + the same strict generated-plan filename/date validator; do not substitute a + source, `.git`, or arbitrary `docs/plans/` path in either invocation. +4. Present in chat: objective, proposed-changes summary, implementation + sequence, top risks, open questions, and the plan file path. Do not paste + the whole document into chat. + +## Deepen mode + +`/gitnexus-plan deepen ` strengthens an existing plan in place +instead of creating a new one: + +1. Resolve the target repository and normalized repo-relative plan candidate, + then load it with `scripts/evidence-provenance.mjs read-plan --repo +--generated-plan ` exactly as specified in + `references/evidence-provenance.md`. Reject a missing, external, escaping, + symlinked, or differently scoped path. Decode and parse only the receipt's + exact `plan_bytes_base64`; retain its canonical `generated_plan_path` and + `plan_digest` unchanged for the entire Deepen session. +2. Re-run Phase 1 in full — analyzer provenance check and freshness gate (a + Deepen run is its own session, with its own refresh budget). +3. **Re-anchor before re-pinning.** Recompute the plan's global dirty digest + and cited-path manifest as well as comparing its old HEAD pin with current + HEAD. Changed, renamed, deleted, mixed, or newly absent cited paths get + their ranges re-read — or the claim downgraded — _before_ the pin and + provenance snapshot move. Moving only the commit pin silently launders + dirty or stale claims as verified. +4. Escalate to `depth: deep` (impact_depth 3, clusters/processes read) + unless the invocation overrides knobs explicitly. +5. Seed the ledger from the plan's §11 pack, then re-verify: every + `[graph]`/`[inferred]` claim gets a targeted pass toward `[verified]`; + every `[assumed]` claim is resolved or kept with its reason; direct + (d=1) dependent accounting is re-checked against the refreshed graph; + PDG slices are built or expanded for the central functions when the + layer is present. +6. **Reconcile execution state.** If `gitnexus-work` already landed commits + for this plan (a mid-execution route-back), mark the §7 steps present at + HEAD as completed and re-sequence the remainder — the rewritten plan must + be executable from the top without redoing landed steps. +7. Strengthen whatever the deeper pass showed thin — test scenarios, risks, + Definition of Done — and carry claim-tag upgrades through the prose. +8. Rewrite the **same canonical file** through + `scripts/evidence-provenance.mjs write-plan --replace +--expected-plan-path +--expected-plan-digest `: same 13 sections, + context pack kept in sync, evidence header updated. `--replace` is reserved + for Deepen mode, and both expected values must come from the same read-plan + receipt; any digest/path mismatch blocks publication. Retain the successful receipt's + `prior_plan_backup_git_path`; it names the verified Git-admin backup of the + displaced plan. Summarize the delta in chat: claims upgraded, claims that + failed re-verification, sections changed, and that backup path. + +## Configuration + +Baseline defaults — the Phase 0 category posture overrides them, and inline +`key:value` tokens before the task text override both (the repo has no +skill-config file mechanism; invocation args are the mechanism): + +| Knob | Default | Meaning | +| --------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| `depth` | by category | `narrow` = `impact_depth` 1, PDG only if one function is clearly central; `default` = this table; `deep` = `impact_depth` 3 + clusters/processes read | +| `form` | by category | `compact` (core sections + mini-pack, ≤80 lines excl. pack — see `references/plan-template.md`) or `full` (all 13 sections) | +| `impact_depth` | 2 | `maxDepth` for `impact` | +| `pdg_data_depth` | 2 | Data-dependence hops in the PDG slice | +| `pdg_control_depth` | 2 | Control-dependence hops in the PDG slice | +| `max_primary_symbols` | 5 | Ledger budget (active symbols; discards don't count) | +| `max_related_symbols` | 20 | Ledger budget (active symbols; discards don't count) | +| `max_snippet_lines` | 30 | Longest source excerpt quoted in the plan | +| `freshness` | by category | `strict` (full-plan categories) = refresh a stale index (and a missing PDG layer) with `analyze --index-only [--pdg]` before relying on the graph; `accept` (compact categories) = plan on the current graph, source-weighted and labelled, refreshing only if a graph claim becomes load-bearing | + +## Fallback mode (GitNexus or PDG unavailable) + +1.

Schema 1 is legacy and deliberately +rejected, so the executor must conservatively re-anchor it under schema 2. + +After the snapshot is in the fully composed document, publish its exact UTF-8 +bytes through the same helper: + +```bash +node /scripts/evidence-provenance.mjs write-plan \ + --repo "$PWD" \ + --generated-plan docs/plans/YYYY-MM-DD-gitnexus-plan-example-change-plan.md \ + < /path/to/outside-repo-scratch-plan.md +``` + +For Deepen only: + +```bash +node /scripts/evidence-provenance.mjs write-plan \ + --repo "$PWD" \ + --generated-plan docs/plans/YYYY-MM-DD-gitnexus-plan-example-change-plan.md \ + --replace \ + --expected-plan-path docs/plans/YYYY-MM-DD-gitnexus-plan-example-change-plan.md \ + --expected-plan-digest 'sha256:' \ + < /path/to/outside-repo-scratch-plan.md +``` + +Initial planning never passes `--replace`; an existing destination is an +error. Deepen mode rewrites the same path by adding `--replace`, +`--expected-plan-path `, and +`--expected-plan-digest `. Standard input must be +valid UTF-8 and at most 16 MiB. A successful write prints a JSON receipt with +the normalized `generated_plan_path` and `bytes_written`. A successful Deepen +write also returns `prior_plan_backup_git_path`, a durable Git-admin path for +the displaced plan. The CLI rejects every option that does not apply to its +selected command; the direct API likewise requires literal booleans and exact +digest strings rather than truthy coercion. + +## Path contract + +Every Git path and CLI path must be valid UTF-8, already normalized to Unicode +NFC, and a nonempty POSIX repo-relative path. NUL, backslash, absolute/drive +paths, empty components, and `.` or `..` components are rejected. The helper +does not silently repair or alias them. Invalid UTF-8 from Git, non-NFC names, +unmerged index stages, unsupported Git modes, sockets/devices/FIFOs, unreadable +objects, symlink traversal in a parent path component, or a repository mutation +observed during the snapshot fail closed. + +The generated-plan path is always repo-relative under schema 2. Snapshot +exclusion and writing require exactly +`docs/plans/YYYY-MM-DD-gitnexus-plan-<3-5-word-kebab-slug>.md`, including a +valid calendar date; they cannot target `.git`, source, configuration, or an +arbitrary repo file. For compatibility with documented and legacy plans, +`read-plan` accepts normalized files matching `docs/plans/*gitnexus-plan*.md`, +while retaining the same descriptor-anchored containment checks. That read +compatibility does not widen the writer. External output has no schema-2 +representation. The snapshot exclusion is one exact normalized path +comparison. No glob, directory, basename, or `docs/plans/`-wide exclusion is +permitted. If the exact path is a rename endpoint, only that endpoint record is +excluded. + +## Safe existing-plan read contract + +`read-plan` fails closed unless Linux `/proc/self/fd`, `O_DIRECTORY`, and +`O_NOFOLLOW` are available. It resolves the exact Git top-level, opens the +repository root and every plan parent as held no-follow directory descriptors, +rejects missing, symlink, non-directory, and escaping parents, and opens the +leaf with `O_NOFOLLOW`. It reads at most 16 MiB from that held file descriptor, +requires valid UTF-8, hashes the exact bytes, then proves both the parent chain +and lexical leaf still name the same held objects before returning its receipt. +Neither Deepen nor work may parse bytes obtained before or outside this receipt. + +## Safe generated-plan write contract + +The writer fails closed unless Linux `/proc/self/fd`, `O_DIRECTORY`, +`O_NOFOLLOW`, and Python 3 with libc `renameat2(RENAME_NOREPLACE)` support are +available. Python may live in `/usr/local`, a Nix profile, or another absolute +PATH directory, but the helper accepts only a resolved executable and +containing directory owned by root or the current user and not writable by +group/other. The resolved executable is opened without following links and +invoked through that held descriptor. Relative PATH entries are ignored. The plan parent and the +repository's Git-admin directory must also share a filesystem. It resolves +the target repository's exact Git top-level, opens that root and every +destination parent as held no-follow directory descriptors, creates missing +parents relative to those descriptors, and proves the descriptor and lexical +chains still identify the same directories at the write boundary. A symlink +or non-directory parent, an escaping resolved path, a symlink/non-regular final +target, or a parent swap is an error. + +The writer creates a random exclusive temporary file relative to the held final +parent descriptor and keeps its no-follow descriptor open. It writes and +flushes the bytes, binds the temporary name to the opened inode, and hashes the +open file before publication. Immediately before publication it revalidates +the parent and the temporary path, inode, size, and digest. Publication uses an +atomic no-replace move relative to the held directory descriptor. Initial mode +therefore cannot overwrite a destination that appears after the absent check. +The writer then flushes the directory and revalidates the committed path by +opening it with `O_NOFOLLOW`, hashing both the original temporary fd and the +path-bound fd, and performing a second descriptor-anchored path identity check +after hashing. A detected mutation or replacement aborts instead of accepting +mixed-era output. + +`--replace` accepts only a pre-existing regular file and is reserved for +Deepen; without it, accidental overwrite is rejected. It also requires the +exact canonical `generated_plan_path` and `plan_digest` from the same session's +`read-plan` receipt. The expected path must exactly equal the write +destination, so identical bytes from one plan cannot authorize another plan. +Immediately before +preservation, the writer hashes the still-held prior-plan fd and rejects any +digest, inode, or path mismatch, including same-inode edits and changes between +read and write. It then atomically moves the current destination without +replacement to a random `gitnexus-plan-backups/` file under the resolved +Git-admin directory and verifies the moved inode and digest against that held +fd. Only then does it publish the new plan with the same atomic no-replace +primitive. A destination that reappears at either boundary is left untouched. + +Every newly created plan or vault directory is fsynced and then fsynced into +its containing directory. Every cross-directory preservation move fsyncs both +its source and destination directories before success or a recovery path is +reported. After temporary bytes exist, a failed publication or verification preserves +every available prior, displaced, unpublished, or intended plan in that +Git-admin vault before reporting failure. Each reported recovery is reopened +from a freshly resolved Git root and verified before the error names it as +`git-path:gitnexus-plan-backups/`. Resolve that value with +`git rev-parse --git-path gitnexus-plan-backups/`; never interpret +it as a repo-relative working-tree path. This remains valid if the held plan +parent was renamed after publication. The writer never reports recovery +through a stale lexical parent and never performs an identity-check-then-unlink +rollback that could delete a racer's replacement. Read-only or unsupported +checkouts produce a blocking error. Callers must not bypass the helper, +redirect to an external path, or weaken these checks. + +## Canonical bytes + +The `global_dirty_digest.value` is lowercase SHA-256 (without a `sha256:` +prefix) over this byte stream. All textual values are their exact UTF-8 bytes. +`NUL` below is one `0x00` byte. + +1. Prefix fields, each followed by NUL, then one additional NUL: + `gitnexus-evidence-provenance`, `schema_version`, `2`. +2. Zero or more records sorted by unsigned lexicographic comparison of the + normalized path's UTF-8 bytes. Locale and filesystem order are forbidden. +3. Each record is `record` + NUL, then the following fixed-order sequence of + `field-name` + NUL + `field-value` + NUL pairs, then one additional NUL: + `path`, `state`, `head_kind`, `index_kind`, `worktree_kind`, + `untracked_kind`, `rename_from`, `rename_to`, `head_digest`, + `index_digest`, `worktree_digest`, `untracked_digest`. +4. The literal `absent` represents every unavailable rename endpoint, object + kind, and layer digest in canonical bytes. It is never an empty string. + +The schema's canonicalization literal is exactly +`gitnexus-evidence-provenance-v2 NUL-framed UTF-8 records`. The fixed field +count plus the extra NUL after prefix/record makes framing unambiguous; values +cannot contain NUL. Duplicate normalized paths are rejected. + +## Records, renames, and states + +The raw dirty set comes from Git porcelain v2 with NUL termination, all +untracked files, submodule inspection enabled, a fixed 50% rename threshold, +and both `diff.renameLimit=0` and `status.renameLimit=0`, so repository config +cannot cap rename candidates. Raw porcelain facts that share a path are merged +into one canonical record. A rename contributes two endpoint facts: + +- old endpoint: `path=`, `rename_from=absent`, `rename_to=`; +- new endpoint: `path=`, `rename_from=`, `rename_to=absent`. + +Both normally have state `renamed`; record sorting, not old/new role, +determines order. A worktree-dirty rename destination or any endpoint that also +has another fact is `mixed`, with rename metadata retained. When either endpoint +is cited, the cited manifest expands to include both. + +Ordinary `XY` status maps to `mixed` when index and worktree columns are both +dirty, otherwise `deleted` for a deletion, `staged` for index-only change, and +`unstaged` for worktree-only change. `?` is `untracked`. Multiple distinct +facts for the same path become `mixed`; a staged deletion plus a recreated file +therefore retains HEAD/index facts while the filesystem object is recorded in +the untracked layer. `? child/` is Git's embedded-directory marker: the trailing +slash is removed before path normalization and `child` is materialized as one +bounded directory object. A cited path outside the dirty set is `clean`, +`untracked` when it exists only outside Git layers, or `absent` when no layer +exists. + +## Object and digest rules + +Every present layer digest is `sha256:`: + +- HEAD regular/symlink: SHA-256 of the exact Git blob bytes. HEAD directory: + SHA-256 of the exact raw Git tree bytes. HEAD gitlink: SHA-256 of the ASCII + object ID stored by the tree. +- Index regular/symlink: SHA-256 of the stage-0 Git blob bytes. Index gitlink: + SHA-256 of its ASCII object ID. The index has no directory layer. Any + non-stage-0 entry is rejected. +- Tracked worktree regular: raw file bytes, opened without following symlinks. + Symlink: raw link-target bytes. Gitlink: ASCII object ID at the checked-out + nested HEAD, but only after `rev-parse --show-toplevel` proves that the + directory itself is the nested repository root, `HEAD` resolves there, and + porcelain v2 reports no staged, unstaged, untracked, or ignored nested changes. The + same root, HEAD, and clean-status proof is repeated by the mutation guard. A + dirty, empty, uninitialized, or parent-falling-through gitlink fails closed. + Directory: the v1 directory stream described below. +- A path absent from both HEAD and index places the filesystem object in the + `untracked` layer and marks `worktree` absent. A Git-backed path places it in + `worktree` and marks `untracked` absent. A missing layer uses literal + `absent` for both kind and digest; an empty file is the SHA-256 of zero bytes. + +Filesystem directory bytes use prefix fields +`gitnexus-evidence-directory`, `schema_version`, `1`, the same NUL framing, +and recursive entries sorted by unsigned UTF-8 relative-path bytes. Each entry +has fixed fields `path`, `kind`, `digest`. A single bottom-up filesystem walk +visits each node once and returns each child digest plus the flattened subtree +needed to preserve those canonical bytes; links are never followed. When the +directory is proven to be an exact nested Git top-level, only its administrative +`.git` entry is excluded. Every other child, including working files and nested +directories, remains evidence. + +Each directory object is bounded to 10,000 visited entries, depth 256, and 256 +MiB of regular-file content. Exceeding a bound fails closed. These bounds apply +independently to each top-level directory object materialized by a record. + +HEAD objects are read only from the full object ID captured at snapshot start; +the symbolic `HEAD` name is never re-resolved for layers. Index layers are +parsed from one captured stage-0 listing. The helper guards the corresponding +HEAD/ref/reflog controls and raw index file, compares the captured listing at +the end, and rejects ordinary A-to-B-to-A mutations instead of accepting +mixed-era layers. + +Regular files are read through an `O_NOFOLLOW` descriptor with before/after +identity checks. Symlinks use lstat/readlink/lstat; directories record identity +before and after their inventory. The helper also compares raw porcelain-v2 +status and HEAD at the start and end, then rechecks filesystem guards. An +absent cited path holds a no-follow descriptor for the nearest existing parent +and records the first missing component or leaf; that anchored absence is +checked both before and after the final Git status pass, so a newly created +ignored path cannot evade porcelain. Any observed race rejects the snapshot +rather than emitting mixed-era evidence. diff --git a/.claude/skills/gitnexus-plan/references/pdg-slice.md b/.claude/skills/gitnexus-plan/references/pdg-slice.md new file mode 100644 index 000000000..d6b3da201 --- /dev/null +++ b/.claude/skills/gitnexus-plan/references/pdg-slice.md @@ -0,0 +1,109 @@ +# Building the PDG context slice + +Statement-level evidence for the 1–3 functions most central to the change. +Goal: a compact slice the planning LLM can hold, never a graph dump. + +## Tools (all verified against `gitnexus/src/mcp/tools.ts`) + +| Question | Call | +| --- | --- | +| Under what condition does X run?

Taint and +dependence evidence needs that PDG layer: when the workflow's taint pass +finds it missing, rebuild with `analyze --pdg --index-only` and record the +rebuild in provenance. For local changes, refresh the index so new or +modified source is represented. +If an exact target checkout/index cannot be established, state the limitation +and do not claim a complete graph-backed review. + +## Review workflow + +1. Read the full diff and changed-file list. Separate generated files, + dependency churn, tests, and behavior changes. +2. Run `detect_changes` against the exact surface: + - PR/branch/`...`: `scope: "compare"`, `base_ref: `. + - Explicit `A..B`: `scope: "compare"`, `base_ref: ` from a worktree + at `B`. + - Local: `scope: "staged"`, `"unstaged"`, or `"all"`. + Pass `worktree` when the MCP server is attached elsewhere. +3. Run upstream `impact` with `includeTests: true` for each behaviorally changed + symbol. Prioritize public contracts, shared types, control flow, persistence, + security boundaries, and error handling; skip mechanical/generated changes. +4. Inspect every direct (`d=1`) dependent that is outside the diff. A dependent + outside the diff is a lead, not automatically a bug—verify the changed + contract and caller behavior in source. +5. Use `context` on key or ambiguous symbols and inspect affected execution + flows. Read the surrounding implementation and tests at cited locations. +6. **Taint and dependence pass.** For changed code on trust or data-flow + boundaries — external input, persistence, process execution, network, + auth — run `explain` on the changed files or symbols and judge its + source→sink taint findings against the diff: a flow the change + introduces, or a sanitizer/guard the change removes, is a finding; a + pre-existing flow is context, not a defect of this change. When the + change claims to guard or sanitize something, verify with `pdg_query`: + what controls the changed statement, and where its values flow. This + needs a `--pdg` index; if one cannot be built, state that the taint pass + was skipped rather than implying coverage. +7. Check whether tests exercise the changed behavior, boundary conditions, and + affected flows. Run focused read-only validation when practical. When the + diff refreshes a committed baseline, fingerprint, or golden, re-run the + exact CI check command against the head instead of trusting the committed + value — a stale artifact is invisible in the diff and fails only in CI. +8. Reconcile graph evidence with the raw diff. New files, dynamic dispatch, + configuration, reflection, and untracked content may require direct review + even when graph results are empty. Version and invalidation constants are + review surface: when the diff changes what gets emitted or persisted, + verify every schema/version constant gating caches, incremental + writebacks, and fingerprint baselines was bumped or regenerated — in + GitNexus itself, for example: `INCREMENTAL_SCHEMA_VERSION` (the + incremental write set covers only changed files, so new cross-file edges + never reach an existing index without the bump), the parse-store + `SCHEMA_BUMP`, and both bench fingerprint sets. + +## Expert lenses + +Depth comes from matching reviewers to what actually changed, not from one +generalist pass. After workflow step 2, group the changed files and symbols +by the functional areas the graph already knows — the index's cluster +listing; `context` names each symbol's cluster — and give each touched area +an expert lens: a reviewer charged with that domain's contracts, invariants, +and failure modes, grounded in the repo's own material (architecture docs, +agent rules, the domain's tests) before judging the diff. A lens verifies, +not just reads: when the changed code is a pure function reachable from the +repo's own toolchain — parsers, extractors, capture emitters, formatters — +execute it on the candidate failing shape (a scratch probe, deleted +afterward) and cite the observed output. An empirical probe outranks source +reading in the evidence hierarchy; role swaps, dead branches, and +error-recovery-dependent behavior repeatedly pass a reading and fail a +ten-line probe. The numbered +workflow runs exactly once; dispatch the lens passes after step 6, handing +each lens the evidence already collected rather than letting lenses repeat +the `impact`, `context`, or taint calls. In GitNexus +itself, for example: shared ingestion-pipeline changes get an ingestion +expert plus one language expert per changed language extractor; embeddings +changes an embeddings expert; LadybugDB/storage changes a Ladybug expert. + +Four cross-cutting lenses run regardless of domain: + +- **Architectural fit** — the change lands where the architecture says the + concern lives, reuses existing seams, and adds no parallel structure. +- **Language conformance** — the repo's own type/lint/test contract as + configured (tsconfig strictness, lint rules, test conventions); in a + strict TypeScript repo, for example: strictness intact, no `any`/`as any` + escapes, module boundaries typed. Judge by the repo's contract, never a + universal style bar. +- **Definition of Done** — changed behavior has tests, docs the change makes + stale are updated, and sync/drift guards (shipped copies, manifests, + changelogs) still hold. +- **Simplicity** — YAGNI and clear-code check: flag speculative abstraction, + unused knobs, and overengineering; the smallest diff that meets the + Definition of Done is the standard. + +Scale effort to the surface: a single-domain change of a few files gets one +combined pass covering its domain lens plus the four cross-cutting checks; +a multi-domain change gets one lens per touched area — run as parallel +subagents where the harness supports them, each scoped to its own files +plus the shared graph evidence, and as sequential passes otherwise. Never +spawn a lens for a domain the diff does not touch. Merge lenses that ground +in the same material — two lenses reading the same files pay twice for one +read's coverage, so give one reviewer both charges. Where the harness +offers model or effort tiers, run mechanical lenses (rename sweeps, +doc-consistency checks) on a cheaper tier and reserve the strongest engine +for adversarial judgment.

Parse the §11 `implementation_context` pack: `acceptance_criteria`, + `evidence_provenance`, `primary_symbols`, `related_symbols`, + `files_to_modify`, `execution_path`, `pdg_constraints`, + `architectural_patterns`, `tests`, `verification_commands`, `risks`, + `assumptions`, `open_questions`, `avoid`.

Before relying on it, require exact byte-for-byte + equality between the read-plan receipt's canonical `generated_plan_path` + and `evidence_provenance.generated_plan_path`. +3. **Two-layer drift check — always recompute.** Even when current HEAD is the + same HEAD as the plan pin, recompute both the canonical global dirty digest + and the sorted cited-path manifest. Read + `references/evidence-provenance.md`, then invoke this skill's + `scripts/evidence-provenance.mjs` with the plan's exact + `generated_plan_path`, every cited manifest path, and schema version 2. + Never recreate its bytes in shell or prose.

Honor the generated-plan exclusion exactly; do not + exclude all plans. +4. **Re-anchor on either mismatch.** Missing or legacy provenance, a HEAD + mismatch, or a global dirty digest mismatch requires a conservative + re-anchor before work: + - Diff every cited-path manifest entry. Changed cited paths — including + staged-only, unstaged-only, deleted, both rename endpoints, mixed + staged+unstaged, and disappeared untracked paths — get their cited ranges + re-read before reliance. + - Compare the current whole-tree dirty set with the pinned global digest. + New uncited dirty paths get a scope assessment: determine whether they + overlap the plan, requirements, tests, or a key technical decision; do not + silently ignore them merely because they are uncited. + - Unreadable or unclassifiable cited evidence blocks every dependent step + until it can be restored, read, or resolved with the user. Never substitute + an invented digest or treat absence as an empty file. + - Keep the re-anchor result in session state; never mutate the plan body. + Use Deepen only if reconciliation invalidates scope, requirements, a key + technical decision (KTD), or the planned implementation seam. Ordinary + byte drift that leaves those decisions valid is re-verified locally. +5. **Re-verify `assumptions` cheaply** (each one names what to check). + A failed assumption is a stop-and-replan signal for the steps that + depend on it, not something to code around silently. +6. Note `open_questions` — if one blocks a step and the answer materially + changes the work, ask the user before that step, not after. +7. **Pre-completed check.** If commits for this plan already exist on the + branch (a prior partial run, or a post-route-back Deepen cycle), verify + which §7 steps have landed at HEAD: those are skipped and reported as + pre-completed, and execution resumes at the first unlanded step. All + steps landed → report that and stop. + +## Phase 2 — Environment + +- On the default branch → create a feature branch named from the plan slug. + On a feature branch already → stay only if it is meaningful _for this + plan_ (name matches the plan slug, or the user confirms); otherwise + branch from here with the slug name. +- If the plan document is not yet committed, commit it now + (`docs(plans): add plan`) — the plan travels with the work it + drives, and the final review diff then includes it. +- Confirm the `verification_commands` from the pack actually run in this + checkout (dependencies installed, builds present) before starting, not + after the last step. + +### Build-current/index-current procedure + +This is the single graph-freshness procedure owned by `gitnexus-work`; it +applies in plan mode and direct mode. Before every graph-dependent `impact` +query, run the Build-current/index-current procedure. Before final graph +verification, run the same Build-current/index-current procedure again. + +1. Capture current HEAD and working-tree provenance. Read + `gitnexus://repo//context` and use its typed `index.commit` and + `index.runner_identity` receipt — never infer analyzer identity from prose, + timestamps, or a path alone. Compare `index.commit` with current HEAD. A + current receipt has `schemaVersion: 4`, resolved runtime path/version, CLI + version, invoked-artifact path/digest, build + kind/root/canonicalization/digest, and dependency-runtime + manifest/lockfile/canonicalization/package-count/artifact-count/digest. Its + dependency canonicalization is + `gitnexus-analyzer-dependency-runtime-v4`. The dependency-runtime digest + covers resolved package metadata and complete loadable package payloads, + including JavaScript, JSON, native, Wasm, and parser artifacts; schema-1, + schema-2, and schema-3 receipts are legacy/stale (the MCP context labels + them `runner_identity_schema_status: legacy-or-unknown`). Require MCP + `index.incomplete_reasons: []`. Run the exact candidate CLI's + `status --json` command and require `index.runnerIdentityStatus: current`, + `index.incompleteReasons: []`, and top-level `status: up-to-date`. The + status comparator checks every semantic field while deliberately excluding + only diagnostic `invokedArtifact`; a worker-authored persisted receipt and + the CLI's live receipt may therefore differ in that field without becoming + stale. Missing, malformed, differently versioned, semantically unequal, or + incomplete receipts are unknown/stale, not a match. +2. Relationship-affecting committed and uncommitted edits invalidate + freshness after the last successful procedure run. This includes staged, + unstaged, untracked, deleted, or renamed analyzer/source/config changes + that can alter symbols or edges. Any such edit between steps requires an + inter-step refresh before the next graph query, even when HEAD did not move. +3. If the typed runner receipt is stale or unknown in an analyzer-source + checkout, build current local source using the verified package script. In + this repo: `cd gitnexus && npm run build`. Resolve the package's `bin` + target and run that exact artifact's `status --json` command to capture its + current receipt. Source/build timestamps are a conservative rebuild + trigger, not proof that an artifact is current. +4. Invoke that exact freshly built local CLI from the target repo root with + PDG layers enabled. In this repo: + `node gitnexus/dist/cli/index.js analyze --index-only --pdg`. + Add `--force` when the persisted receipt was absent, malformed, + differently versioned, or unequal so an already-up-to-date fast path cannot + leave legacy/stale provenance in place. The usual project-runner form, + `node .gitnexus/run.cjs analyze`, is acceptable only when its proven runner + identity resolves to that same freshly built artifact. Do not fall back to + an older project runner, global install, or package download after + resolving/building the local artifact. +5. Re-read index context, rerun the exact invoked CLI's `status --json`, and + prove the post-refresh `index.commit` equals current HEAD, MCP + `index.incomplete_reasons` is empty, and its complete + `index.runner_identity` equals status `index.runnerIdentity` (the persisted + receipt). Require status `index.runnerIdentityStatus: current`, empty + `index.incompleteReasons`, and top-level `status: up-to-date`; do not require + raw equality with `current.runnerIdentity` because `invokedArtifact` is a + diagnostic entrypoint deliberately excluded from semantic freshness. + Record the dirty-state digest indexed in this procedure so same-HEAD + uncommitted edits can invalidate it later. +6. Any build, refresh, metadata-read, or identity-verification failure blocks + graph-dependent impact work and final completion. Report the failing + command and evidence; do not continue on an older graph. + +## Phase 3 — Execute the Implementation Sequence + +Work through plan §7 step by step, in order. For each step: + +1. **Fresh impact before editing.** Run the Build-current/index-current + procedure immediately before every graph-dependent + `impact {target, direction: "upstream"}` query. Then account for every + direct (d=1) dependent. HIGH or CRITICAL risk → surface it to the user + with the blast radius before proceeding (repo mandate — see AGENTS.md + GitNexus rules). +2. **Honor the constraints.** `pdg_constraints` entries state ordering and + dependence facts the change must preserve; `avoid` entries are hard + prohibitions; `architectural_patterns` name the shape to mirror (read the + example location before inventing one). +3. **Implement minimally.** The smallest change that completes the step, + following the surrounding code's conventions. +4. **Test from the plan's scenarios.** Each `tests[]` scenario (input → + action → expected outcome) becomes a real test in the named file. Add + coverage the plan missed if the step's behavior demands it; never delete + or weaken an assertion to make a step pass. Prove a new regression test + discriminates: when the failure mode is subtle, run it once against the + pre-fix tree (write the test before the fix, or stash the fix) and watch + it fail — a test that passes both ways pins nothing. +5. **Verify.** Run the step-relevant `verification_commands` (they carry + their build prerequisites; use them as written). If any part of the + change executes from build output — worker entrypoints, dist-shipped + CLIs, bundled assets — rebuild that output before every verification + run: a pass or fail against outdated build output is noise, and "the + fix doesn't work" is more often "the fix never loaded". +6. **Commit atomically.** `detect_changes {scope: "staged"}` before every + commit to confirm only the expected symbols and flows are affected + (repo mandate); then one conventional commit per step. Run stage → + `detect_changes` → commit as one unbroken sequence from the repository + root — interleaving other work between the gate and the commit is how + the gate gets skipped. Unexpected + affected flows → investigate before committing, not after. + +A relationship-affecting implementation edit or commit invalidates the +procedure's prior proof. The next step must perform the required inter-step +refresh before its impact query; final verification refreshes again after the +last edit. + +Steps are independently actionable: after any commit the tree is coherent. +If a step reveals the plan is wrong, stop that step, re-verify the affected +claims at HEAD, and either adapt (small, in-scope deviation — record it in +the commit message and final summary) or route back to `gitnexus-plan` +Deepen mode (structural miss) — with a one-line ask to the user when the +choice isn't obvious. + +## Phase 4 — Finish + +1. Run the full `verification_commands` suite once, at the end, even if + every step already passed individually. +2. Walk plan §13 (Definition of Done) and the pack's `acceptance_criteria` + item by item; anything unmet is either finished now or reported as + explicitly unmet — never silently dropped. +3. **Verify the final knowledge graph.** Before final graph verification, run + the same Build-current/index-current procedure after the last edit, even + when no commit landed or HEAD still equals the original pin. Then run + `detect_changes {scope: "all"}` (or the repo's equivalent final graph + check) against that proven-current index and account for every unexpected + symbol or flow. A procedure failure blocks completion. +4. Report: steps completed, commits made, deviations from the plan (with + why), assumptions that failed re-verification, DoD status, final indexed + commit and runner identity, and anything deferred. Test failures are + reported with their output, not smoothed over. + +## Never + +- Skip the Phase 3 gates: no symbol edit without `impact`, no commit without + `detect_changes`. +- Expand scope beyond the plan — §12's deferred follow-ups stay deferred. +- Mutate the plan body (committing the file verbatim in Phase 2 is not + mutation), weaken failing tests, or present unverified work as verified. + +## Skill feedback (GitNexus repo only) + +If this run exposed friction in this skill's own instructions — wrong or +missing guidance, a wasted tool budget, a phase that misrouted — and the repo +carries `eval/workflow_bench/`, append one JSON line to +`eval/workflow_bench/learnings.jsonl` (create the file if absent): +`{"skill": "gitnexus-work", "date": "YYYY-MM-DD", "task": "", "friction": "", "suggestion": ""}`. +Never edit this skill file itself from a live task: improvements go through +the offline candidate loop (`eval/workflow_bench/README.md` § Prompt and +skill evolution loop), where a candidate must beat the incumbent on the +paired benchmark before a human merges it. diff --git a/.claude/skills/gitnexus-work/references/evidence-provenance.md b/.claude/skills/gitnexus-work/references/evidence-provenance.md new file mode 100644 index 000000000..c686599da --- /dev/null +++ b/.claude/skills/gitnexus-work/references/evidence-provenance.md @@ -0,0 +1,272 @@ +# Evidence provenance serializer v2 and safe plan writer + +This file is the normative byte contract for `evidence_provenance` schema 2. +The adjacent `scripts/evidence-provenance.mjs` is its executable definition. +`gitnexus-plan` and `gitnexus-work` carry byte-identical copies so either skill +can produce the same snapshot without relying on the other skill's install. +It is also the only supported write boundary for a generated plan.

It reads at most 16 MiB from that held file descriptor, +requires valid UTF-8, hashes the exact bytes, then proves both the parent chain +and lexical leaf still name the same held objects before returning its receipt. +Neither Deepen nor work may parse bytes obtained before or outside this receipt. + +## Safe generated-plan write contract + +The writer fails closed unless Linux `/proc/self/fd`, `O_DIRECTORY`, +`O_NOFOLLOW`, and Python 3 with libc `renameat2(RENAME_NOREPLACE)` support are +available. Python may live in `/usr/local`, a Nix profile, or another absolute +PATH directory, but the helper accepts only a resolved executable and +containing directory owned by root or the current user and not writable by +group/other. The resolved executable is opened without following links and +invoked through that held descriptor. Relative PATH entries are ignored. The plan parent and the +repository's Git-admin directory must also share a filesystem. It resolves +the target repository's exact Git top-level, opens that root and every +destination parent as held no-follow directory descriptors, creates missing +parents relative to those descriptors, and proves the descriptor and lexical +chains still identify the same directories at the write boundary. A symlink +or non-directory parent, an escaping resolved path, a symlink/non-regular final +target, or a parent swap is an error. + +The writer creates a random exclusive temporary file relative to the held final +parent descriptor and keeps its no-follow descriptor open. It writes and +flushes the bytes, binds the temporary name to the opened inode, and hashes the +open file before publication. Immediately before publication it revalidates +the parent and the temporary path, inode, size, and digest. Publication uses an +atomic no-replace move relative to the held directory descriptor. Initial mode +therefore cannot overwrite a destination that appears after the absent check. +The writer then flushes the directory and revalidates the committed path by +opening it with `O_NOFOLLOW`, hashing both the original temporary fd and the +path-bound fd, and performing a second descriptor-anchored path identity check +after hashing. A detected mutation or replacement aborts instead of accepting +mixed-era output. + +`--replace` accepts only a pre-existing regular file and is reserved for +Deepen; without it, accidental overwrite is rejected. It also requires the +exact canonical `generated_plan_path` and `plan_digest` from the same session's +`read-plan` receipt. The expected path must exactly equal the write +destination, so identical bytes from one plan cannot authorize another plan. +Immediately before +preservation, the writer hashes the still-held prior-plan fd and rejects any +digest, inode, or path mismatch, including same-inode edits and changes between +read and write. It then atomically moves the current destination without +replacement to a random `gitnexus-plan-backups/` file under the resolved +Git-admin directory and verifies the moved inode and digest against that held +fd. Only then does it publish the new plan with the same atomic no-replace +primitive. A destination that reappears at either boundary is left untouched. + +Every newly created plan or vault directory is fsynced and then fsynced into +its containing directory. Every cross-directory preservation move fsyncs both +its source and destination directories before success or a recovery path is +reported. After temporary bytes exist, a failed publication or verification preserves +every available prior, displaced, unpublished, or intended plan in that +Git-admin vault before reporting failure. Each reported recovery is reopened +from a freshly resolved Git root and verified before the error names it as +`git-path:gitnexus-plan-backups/`. Resolve that value with +`git rev-parse --git-path gitnexus-plan-backups/`; never interpret +it as a repo-relative working-tree path. This remains valid if the held plan +parent was renamed after publication. The writer never reports recovery +through a stale lexical parent and never performs an identity-check-then-unlink +rollback that could delete a racer's replacement. Read-only or unsupported +checkouts produce a blocking error. Callers must not bypass the helper, +redirect to an external path, or weaken these checks. + +## Canonical bytes + +The `global_dirty_digest.value` is lowercase SHA-256 (without a `sha256:` +prefix) over this byte stream.

Duplicate normalized paths are rejected. + +## Records, renames, and states + +The raw dirty set comes from Git porcelain v2 with NUL termination, all +untracked files, submodule inspection enabled, a fixed 50% rename threshold, +and both `diff.renameLimit=0` and `status.renameLimit=0`, so repository config +cannot cap rename candidates. Raw porcelain facts that share a path are merged +into one canonical record. A rename contributes two endpoint facts: + +- old endpoint: `path=`, `rename_from=absent`, `rename_to=`; +- new endpoint: `path=`, `rename_from=`, `rename_to=absent`. + +Both normally have state `renamed`; record sorting, not old/new role, +determines order. A worktree-dirty rename destination or any endpoint that also +has another fact is `mixed`, with rename metadata retained. When either endpoint +is cited, the cited manifest expands to include both. + +Ordinary `XY` status maps to `mixed` when index and worktree columns are both +dirty, otherwise `deleted` for a deletion, `staged` for index-only change, and +`unstaged` for worktree-only change. `?` is `untracked`. Multiple distinct +facts for the same path become `mixed`; a staged deletion plus a recreated file +therefore retains HEAD/index facts while the filesystem object is recorded in +the untracked layer. `? child/` is Git's embedded-directory marker: the trailing +slash is removed before path normalization and `child` is materialized as one +bounded directory object. A cited path outside the dirty set is `clean`, +`untracked` when it exists only outside Git layers, or `absent` when no layer +exists. + +## Object and digest rules + +Every present layer digest is `sha256:`: + +- HEAD regular/symlink: SHA-256 of the exact Git blob bytes. HEAD directory: + SHA-256 of the exact raw Git tree bytes. HEAD gitlink: SHA-256 of the ASCII + object ID stored by the tree. +- Index regular/symlink: SHA-256 of the stage-0 Git blob bytes. Index gitlink: + SHA-256 of its ASCII object ID. The index has no directory layer. Any + non-stage-0 entry is rejected. +- Tracked worktree regular: raw file bytes, opened without following symlinks. + Symlink: raw link-target bytes. Gitlink: ASCII object ID at the checked-out + nested HEAD, but only after `rev-parse --show-toplevel` proves that the + directory itself is the nested repository root, `HEAD` resolves there, and + porcelain v2 reports no staged, unstaged, untracked, or ignored nested changes. The + same root, HEAD, and clean-status proof is repeated by the mutation guard. A + dirty, empty, uninitialized, or parent-falling-through gitlink fails closed. + Directory: the v1 directory stream described below. +- A path absent from both HEAD and index places the filesystem object in the + `untracked` layer and marks `worktree` absent. A Git-backed path places it in + `worktree` and marks `untracked` absent. A missing layer uses literal + `absent` for both kind and digest; an empty file is the SHA-256 of zero bytes. + +Filesystem directory bytes use prefix fields +`gitnexus-evidence-directory`, `schema_version`, `1`, the same NUL framing, +and recursive entries sorted by unsigned UTF-8 relative-path bytes. Each entry +has fixed fields `path`, `kind`, `digest`. A single bottom-up filesystem walk +visits each node once and returns each child digest plus the flattened subtree +needed to preserve those canonical bytes; links are never followed. When the +directory is proven to be an exact nested Git top-level, only its administrative +`.git` entry is excluded. Every other child, including working files and nested +directories, remains evidence. + +Each directory object is bounded to 10,000 visited entries, depth 256, and 256 +MiB of regular-file content. Exceeding a bound fails closed. These bounds apply +independently to each top-level directory object materialized by a record. + +HEAD objects are read only from the full object ID captured at snapshot start; +the symbolic `HEAD` name is never re-resolved for layers. Index layers are +parsed from one captured stage-0 listing. The helper guards the corresponding +HEAD/ref/reflog controls and raw index file, compares the captured listing at +the end, and rejects ordinary A-to-B-to-A mutations instead of accepting +mixed-era layers. + +Regular files are read through an `O_NOFOLLOW` descriptor with before/after +identity checks. Symlinks use lstat/readlink/lstat; directories record identity +before and after their inventory. The helper also compares raw porcelain-v2 +status and HEAD at the start and end, then rechecks filesystem guards. An +absent cited path holds a no-follow descriptor for the nearest existing parent +and records the first missing component or leaf; that anchored absence is +checked both before and after the final Git status pass, so a newly created +ignored path cannot evade porcelain. Any observed race rejects the snapshot +rather than emitting mixed-era evidence. diff --git a/.claude/skills/gitnexus-work/scripts/evidence-provenance.mjs b/.claude/skills/gitnexus-work/scripts/evidence-provenance.mjs new file mode 100644 index 000000000..181d2120b --- /dev/null +++ b/.claude/skills/gitnexus-work/scripts/evidence-provenance.mjs @@ -0,0 +1,2084 @@ +#!/usr/bin/env node + +import { createHash, randomBytes } from 'node:crypto'; +import fs from 'node:fs'; +import path from 'node:path'; +import process from 'node:process'; +import { spawnSync } from 'node:child_process'; +import { fileURLToPath } from 'node:url'; + +export const EVIDENCE_PROVENANCE_SCHEMA_VERSION = 2; +export const EVIDENCE_PROVENANCE_CANONICALIZATION = + 'gitnexus-evidence-provenance-v2 NUL-framed UTF-8 records'; + +const ABSENT = 'absent'; +const OBJECT_KINDS = new Set(['regular', 'symlink', 'gitlink', 'directory', ABSENT]); +const STATES = new Set([ + 'clean', + 'staged', + 'unstaged', + 'untracked', + 'deleted', + 'renamed', + 'mixed', + ABSENT, +]); +const RECORD_FIELDS = [ + 'path', + 'state', + 'head_kind', + 'index_kind', + 'worktree_kind', + 'untracked_kind', + 'rename_from', + 'rename_to', + 'head_digest', + 'index_digest', + 'worktree_digest', + 'untracked_digest', +]; +const UTF8_FATAL = new TextDecoder('utf-8', { fatal: true }); +const MAX_GIT_OUTPUT = 1024 * 1024 * 1024; +const MAX_PLAN_BYTES = 16 * 1024 * 1024; +const GENERATED_PLAN_READ_PATTERN = /^docs\/plans\/[^/]*gitnexus-plan[^/]*\.md$/; +const GENERATED_PLAN_WRITE_PATTERN = + /^docs\/plans\/(\d{4}-\d{2}-\d{2})-gitnexus-plan-[a-z0-9]+(?:-[a-z0-9]+){2,4}\.md$/; +export const DIRECTORY_LIMITS = Object.freeze({ + maxEntries: 10_000, + maxDepth: 256, + maxBytes: 256 * 1024 * 1024, +}); + +function sha256(bytes) { + return `sha256:${createHash('sha256').update(bytes).digest('hex')}`; +} + +function statIdentity(stat) { + return [stat.dev, stat.ino, stat.mode, stat.nlink, stat.size, stat.mtimeNs, stat.ctimeNs] + .map(String) + .join(':'); +} + +function assertStableIdentity(before, after, label) { + if (statIdentity(before) !== statIdentity(after)) { + throw new Error(`${label} changed while evidence was being read`); + } +} + +function hashFile(file, mutationGuards, directoryTraversal) { + const hash = createHash('sha256'); + const noFollow = fs.constants.O_NOFOLLOW ?? 0; + const fd = fs.openSync(file, fs.constants.O_RDONLY | noFollow); + const buffer = Buffer.allocUnsafe(1024 * 1024); + try { + const before = fs.fstatSync(fd, { bigint: true }); + if (!before.isFile()) throw new Error(`Expected a regular file at ${file}`); + if (directoryTraversal) { + directoryTraversal.bytes += before.size; + if (directoryTraversal.bytes > BigInt(DIRECTORY_LIMITS.maxBytes)) { + throw new Error(`Directory inventory exceeds ${DIRECTORY_LIMITS.maxBytes} content bytes`); + } + } + for (;;) { + const count = fs.readSync(fd, buffer, 0, buffer.length, null); + if (count === 0) break; + hash.update(buffer.subarray(0, count)); + } + const after = fs.fstatSync(fd, { bigint: true }); + assertStableIdentity(before, after, file); + mutationGuards.push({ type: 'stat', absolute: file, identity: statIdentity(after) }); + } finally { + fs.closeSync(fd); + } + return `sha256:${hash.digest('hex')}`; +} + +function git(repo, args, { allowFailure = false, input } = {}) { + const result = spawnSync('git', ['-C', repo, ...args], { + encoding: null, + env: { ...process.env, LANG: 'C', LC_ALL: 'C', GIT_OPTIONAL_LOCKS: '0' }, + input, + maxBuffer: MAX_GIT_OUTPUT, + windowsHide: true, + }); + if (result.error) throw result.error; + if (result.status !== 0 && !allowFailure) { + const stderr = Buffer.from(result.stderr ??

Token +savings on a failed task are flagged, not celebrated, and diff churn +(files/+insertions/−deletions vs the starting commit) is recorded as a cheap +over-engineering proxy.

The report names both selected and skipped +tasks so an omitted cell cannot be mistaken for evidence. + +CE comparator arms never discover a user-level plugin. Supply an exact plugin +release explicitly; both flags are mandatory whenever any `ce_*` arm is +selected: + +```bash +uv run --locked --extra dev python -m workflow_bench.runner \ + --tasks workflow_bench/tasks.scenarios.yaml --runs 3 \ + --model claude-sonnet-4-20250514 \ + --arms workflow ce_workflow \ + --ce-plugin-dir /opt/operator-input/compound-engineering-3.19.0 \ + --ce-plugin-version 3.19.0 +``` + +The runner verifies the manifest version, copies only the plugin manifests, +skills, scripts, and assets into a bounded no-symlink snapshot, and mounts +that snapshot read-only only for CE arms. Every CE result records its exact +plugin version and content-manifest digest. + +Output: `results/wfbench-<timestamp>/results.jsonl` (every run, with session +ids for transcript drill-down) and `report.md` (medians per task per arm, +plus a savings row: input / cache / output tokens, cost, wall time). + +## Trust model — fail-closed Linux containment + +Task files and candidate prose remain untrusted executable inputs. Every +setup, verifier, incumbent, and candidate cell therefore runs in a +preflighted Bubblewrap boundary with a private home/config/temp, a +self-contained clone, a PID namespace, bounded process-tree ownership, and a +deny-by-default environment. Task-declared dependency roots are mounted +read-only, while graph assets are rebuilt by the harness as described below. +Claude runs in bare, +`dontAsk` mode with strict clone-local MCP configuration; Bash children do +not inherit the model credential and their network sandbox denies all +domains. + +Prebuilt task `.gitnexus` assets are rejected. For each task commit, the +harness creates the deterministic parentless snapshot first, removes every +analyzer-visible path or stored source reference to the benchmark harness, +neutralizes target-controlled GitNexus config/ignore files, and builds one +fresh PDG index offline with `--pdg --index-only --no-stats`. It then proves +that neither whole graph nodes nor relationships contain a harness marker and +caches only the bound metadata/database assets for reuse by paired arms. + +Each selected task also declares a bounded hidden `oracle` command and file +set. The harness captures those regular, non-symlink files into an immutable +in-memory snapshot before any arm runs and binds the command, paths, sizes, and +raw bytes into the task digest. Before any task asset or model session, each +disposable clone that contains the benchmark harness is rewritten to a clean, +parentless snapshot without `eval/workflow_bench`; all original refs, reflogs, +and unreachable Git objects are pruned so `git show` cannot recover the hidden +bytes. Only after the model exits (and after the authored-test signal is +collected) does the harness materialize the oracle beneath a private host +root, mount it read-only at a random workspace sibling, and supply that mount +through `GITNEXUS_BENCH_ORACLE_ROOT`. This layout preserves hidden tests' +`../gitnexus` imports as the credited candidate checkout. Authored and hidden +verifiers run with the complete workspace read-only and networking unshared; +hidden stdout/stderr is never persisted. The harness re-checks every oracle +byte and erases the mountpoint before churn/patch capture. Shipped Vitest +oracles use the staged, digest-bound `vitest.config.mts`; a candidate cannot +replace repo test config or setup hooks to make the hidden test vacuously pass. +The hidden command invokes the read-only dependency's Vitest binary directly, +without an `npx` configuration/resolution layer. + +Every evaluated repo-local skill root is over-mounted read-only for the full +model session, and an immutable empty user-level skills directory prevents a +writable `$HOME` skill from shadowing it. Skill-use evidence comes only from +the bounded stream captured directly from Claude stdout by the parent. The +runner parses every event through EOF, requires one final result, correlates +an exact Skill request ID with one later successful result, structurally +redacts the event objects, and stores the canonical redacted JSONL with a +digest. Files written beneath the agent's `$HOME` are never trusted as +evidence. + +Bare mode is deliberately non-interactive: it does not consult a stored +Claude login/keychain or `ANTHROPIC_AUTH_TOKEN`. Supply one explicit API or +proxy key through `GITNEXUS_BENCH_AUTH_TOKEN` (preferred) or `--auth-token`; +the harness maps it to `ANTHROPIC_API_KEY` only for the trusted Claude parent +and scrubs it from agent-launched tools. + +The trusted Claude CLI still needs outbound access to the explicitly supplied +model endpoint. This is not a network broker, so the CLI itself retains that +egress; agent-launched tools do not. Missing Bubblewrap, unsupported hosts, +invalid mounts, or namespace preflight failure stop before model invocation. +Native benchmark execution is therefore Linux/WSL2-only. Evidence assembly +and hand-authored overlay preparation can happen elsewhere, but +`--initial-overlay` does not bypass containment. + +## Prompt and skill evolution loop + +Prompts age as models and tool harnesses change. Treat the current skills and +router thresholds as an incumbent policy, not permanent truth. Candidate +changes run offline in the same throwaway clones as the incumbent; production +skills never rewrite themselves from a live task. + +Build an overlay that mirrors only the canonical repo-local skill paths: + +```text +/tmp/gn-skill-candidate/ +└── .claude/skills/ + ├── gitnexus-plan/SKILL.md + └── gitnexus-work/SKILL.md +``` + +The overlay may contain Markdown files from either of those two skill +trees. The runner rejects every other path, including source, test, and MCP +configuration files, so a candidate cannot improve its score by changing the +task or verifier. Arm selection is derived from the touched skill and must be +exact: a plan-only overlay runs the workflow pair; any work overlay runs both +workflow and direct-work pairs. Subsets and unrelated extra pairs fail before +paid work. For a work overlay: + +```bash +cd eval +uv run --locked --extra dev python -m workflow_bench.runner \ + --tasks workflow_bench/tasks.scenarios.yaml \ + --runs 3 --model claude-sonnet-4-20250514 \ + --arms workflow candidate_workflow \ + workflow_direct candidate_workflow_direct \ + --candidate-overlay /tmp/gn-skill-candidate +``` + +Candidate runs start from the same task commit, then receive a clean ephemeral +commit containing the overlay. `results.jsonl` records the named model, task +commit, task-prompt digest, skill digest, overlay digest, hidden-oracle +command/manifest/content digests, immutable dependency content/manifest +digests, separate authored-test and oracle outcomes, +timestamp, local session ids, and digest-bound parent-captured event-stream +artifacts. Those artifacts are the trajectory evidence: cluster failures and +expensive detours, propose one bounded prompt change, and feed it back as the +next overlay. + +When candidate arms are present the runner also writes schema-3 +`promotion.json`. It +binds the immutable overlay digest, benchmark model, truthful candidate origin +(a named proposer model or `manual-initial-overlay`), selected +task definitions, resolved commits, and exact hidden-oracle bytes/commands, +immutable dependency bytes, committed base digest of every apply +destination, exact required arms, thresholds, and evidence expiry. Its default +deterministic gate is deliberately conservative: + +- at least 3 paired VALID runs per task, zero excluded runs in either arm + (session/infra-error rows therefore block promotion), and a named model; +- the candidate must pass the hidden oracle on every valid run for every task; +- no per-task resolution-rate regression (quality is lexicographically first); +- promotion by resolution needs a margin of at least 2 resolved runs — + a 1-run difference is noise at this run count and falls through to the + efficiency comparison; +- with equal quality, at least 5% median improvement on the promotion metric + (default `cost_usd` — the only CLI-reported number that includes subagent + spend; token metrics count only the main-loop session and flatter + subagent-heavy candidates, so selecting one stamps a warning into + `promotion.json`); +- no individual task may regress the selected efficiency metric by more than + 20%. + +Tune the efficiency signal with `--promotion-metric` and the three +`--promotion-*` thresholds. Applying requires one unique `promote` decision +for every bound candidate arm. The driver then stages every canonical and +shipped mirror, verifies that all destination bytes still match the bound +bases, replaces them as one compare-and-swap set, verifies byte parity, and +rolls every landed replacement back on failure or interruption. +`keep_incumbent` and +`insufficient_evidence` become the next learning queue; their raw +`results.jsonl` rows carry the `session_ids` of the trajectories to inspect. + +Re-run the paired suite whenever the named model or tool harness changes, and +at least every 90 days otherwise. This is prompt-policy optimization using +verified agent trajectories as reward evidence; it is intentionally not +online model-weight RL. The same records can feed a later offline RL pipeline +without weakening today's deterministic promotion boundary. + +### Closing the loop automatically (`evolve.py`) + +`workflow_bench.evolve` automates the three manual arrows — propose, +benchmark, apply — without moving the trust boundary: + +```bash +cd eval +uv run --locked --extra dev python -m workflow_bench.evolve \ + --tasks workflow_bench/tasks.scenarios.yaml \ + --model claude-sonnet-4-20250514 --generations 2 \ + --seed-results results/wfbench-<prior-run> # optional gen-0 evidence +``` + +Each generation: a confined **proposer** session reads the incumbent plan/work +skills, the prior generation's `results.jsonl` +loser rows, their session transcripts and patches, and the learning queue, +then writes ONE bounded candidate overlay plus a reviewer-facing +`proposal.md`. The overlay is re-validated by `candidate_overlay_files` +(same boundary: Markdown under the plan/work trees, nothing else), frozen, +and exercised only by its exact required pairs. Task refs are resolved once +before generation zero and the immutable task bindings are forwarded to every +generated runner invocation, so a moving branch cannot change later evidence. +The deterministic gate then decides. Promotion application rejects older +pre-oracle evidence schemas. `promote` stops the loop; with `--apply` +the authorized frozen bytes +are transactionally applied to the canonical +`.claude/skills/` trees and their shipped mirrors as an ordinary +working-tree diff — committing, CI (`shipped-skills-sync`, +`skills-steering`), and the PR merge stay human. `keep_incumbent` feeds that +generation's trajectories to the next proposer. `--initial-overlay` skips +the generation-0 proposer to benchmark a hand-written candidate; +`--proposer-model` upgrades only the diagnosis session. + +**Learning queue.** Live plan/work skill runs never self-edit (see each +skill's "Skill feedback" section) — instead they may append one-line JSON notes to +`workflow_bench/learnings.jsonl` (gitignored, machine-local like the +transcripts they complement). The proposer reads the queue as hints, not +ground truth: a learning only reaches a shipped skill by surviving the same +paired benchmark as any other candidate. Legacy review/LFG rows are ignored; +those skills do not yet have honest candidate lanes or promotion gates. + +Run the driver on the existing re-evaluation triggers (model/harness change, +90-day staleness), not on a tight schedule — every generation costs ≥3 paired +runs per task, and `--generations` is the only loop bound. + +## Free-model setup (no paid tokens) + +Headless Claude Code honors `ANTHROPIC_BASE_URL`, and litellm (already an +eval dependency) can proxy its Anthropic-compatible `/v1/messages` to a model +that costs nothing — a hosted OpenRouter `:free` variant or a fully local +Ollama model. Config template: `free-model.litellm.yaml`. + +```bash +# 1. Choose a proxy master key and start the proxy +# (pick/edit a model route in the yaml first; keep the proxy on loopback — +# anyone who can reach the port with this key can spend the backend quota) +export LITELLM_MASTER_KEY="$(openssl rand -hex 16)" +uv run --locked --with 'litellm[proxy]' litellm --config workflow_bench/free-model.litellm.yaml --port 4000 + +# 2.

Its fixed cost — freshness + gate incl. analyzer rebuild + re-index, a full 13-section plan, work-phase + re-anchoring — is ~$9–11 per task and needs much larger tasks, plan-reuse + (one plan, several executors/sessions), or plan-as-deliverable flows to + amortize. +- **workflow_direct is close to baseline** (−15% to −55% cost, once slightly + faster wall) — the execution discipline (impact-before-edit, + detect_changes-before-commit) is cheap. It produced noticeably more test + coverage than baseline for near-equal cost on the feature task. +- **Quality didn't differentiate because nothing failed.** The regime where + the workflow should win on *resolve rate* — cross-module tasks where + baselines flail — is the unmeasured cell (`cross-module-parse-retry`), and + the next thing to measure, ideally with `--runs 3+` on a free backend. +- Caveats: n=1 per cell, one repo, one model; churn numbers from this run + predate the intent-to-add/exclude-plans churn fix, so they are not + comparable across arms and are omitted above. + +Routing implication (to revisit as cells fill in): for tasks up to this +size, `gitnexus-work` direct mode or a plain agent is the cost-optimal +route; reserve full `gitnexus-plan` → `gitnexus-work` for cross-module work, +multi-session execution, or when the plan document itself is a deliverable. +If a future run shows the workflow flattering itself here, distrust the run. + +### Cross-module cell (same day, optimized skills, n=1) + +The hardest class — retry-with-backoff across the worker-pool/pipeline +seams, transient-vs-deterministic classification: + +| arm | resolved | cost $ | wall | turns | churn | +| --- | --- | --- | --- | --- | --- | +| workflow | 1/1 | 18.32 | 37m | 107 | 4/+373/−17 | +| **workflow_direct** | 1/1 | **9.53** | **15m** | **52** | 11/+244/−66 | +| baseline | 1/1 | 18.03 | 34m | 98 | 6/+345/−69 | + +(The workflow_direct row is the clean re-run under clone isolation — the +original was contaminated, see the integrity note below.) + +**This is the cell where the discipline pays.** `workflow_direct` — the +execution skill without a planning pass — beat a plain agent by **47% cost +and 56% wall time** on the hardest class while resolving: impact-first +navigation and gated commits prevented the flailing that baseline's 98 +turns represent. The full workflow's premium vanished (−1.6% vs baseline; +−211%..−333% on smaller classes) — fixed costs amortize here, with a less +destructive diff and a durable plan artifact — but it didn't beat direct +mode on any measured axis with the plan consumed only once. Resolve rate +stayed tied across all cells; the savings story belongs to the execution +discipline, and the planning pass is bought for its artifact (multi-session +reuse, review, handoff), not for same-session token savings. + +**Benchmark integrity note (why churn earns its keep):** the original +`workflow_direct` cell reported an impossible 28-turn/$4.71 solve with churn +byte-identical to the workflow arm — because `git worktree add` shares the +ref namespace, the workflow arm's slug branch survived worktree removal, and +the direct arm found and adopted the finished work.

All savings came from the plan side; +this run's work session drew a long test-debugging tail (hence the wall +regression) — single-run variance cuts both ways. The optimizations narrow +the gap but do not flip the regime: the workflow remains ~3.5× baseline on +this task class, so the routing rule above stands unchanged. + +## Writing good tasks + +See `tasks.scenarios.yaml`. Small enough to finish headless, real enough to +require investigation — the workflow's savings come from *not re-reading and +not re-investigating*, which trivial tasks never exercise.

Phase 4 still source-verifies whatever Proposed Changes +will cite, at the pinned commit — seeding replaces exploration, never +verification. + +**Depth is the user's decision, asked once, up front.** In an interactive +session, when the invocation carries no explicit depth signal (no `depth:`, +`form:`, or `freshness:` knob, and not Deepen mode), ask one blocking +question before Phase 1 — how deep should this plan go? + +1. **Quick** — `depth:narrow form:compact freshness:accept`. Fastest useful + plan: 1–2 primary symbols, minimal graph work, core sections only. +2. **Standard** — the category posture above, unchanged. Recommend this + unless the classification argues otherwise. +3. **Deep** — `depth:deep form:full freshness:strict`. All 13 sections, + `impact_depth` 3, clusters/processes read, PDG slices for the central + functions. + +The answer sets the knobs exactly as if they had been typed in the +invocation; explicit knobs win and skip the question. Headless runs never +ask — the category posture applies unchanged. Asking up front replaces +offering to deepen a finished plan afterwards: Deepen mode (below) remains +the mechanism for strengthening an existing plan document — a later session, +review findings, an executor route-back — not a default follow-up question. + +**Turn economy is a deliverable.** The plan is judged on decision quality per +token, not thoroughness theater (measured: a 63-turn plan for a two-line +change — the GitNexus repo's `eval/workflow_bench/`). Stay within the category's tool-call +budget; when the budget runs out with questions still open, record them in +§12 instead of digging further — the executor re-verifies cheaply anyway. + +## Phase 1 — Anchor and freshness + +1. Resolve the target repo: `list_repos` if in doubt, else the indexed repo + covering the working directory. Pass `repo` explicitly on every call when + more than one repo is indexed. +2. Record the repo's current HEAD commit in the ledger — every line-number + citation in the plan is pinned to it. +3. **Resolve and record the analyzer runner** (used by every `analyze` + command in this skill): `node .gitnexus/run.cjs analyze …` when the + project has a runner (a previous analyze dropped it next to the index), + else `gitnexus analyze …` (installed CLI — `npm install -g gitnexus`), + else `npx gitnexus analyze …`. Record its path/version and any available + source/build identity; do not manufacture provenance from timestamps. +4. Read `gitnexus://repo/{name}/context` — codebase overview + staleness check. + **Freshness gate.** Plans built on a stale graph make stale blast-radius + claims — but a re-index is the largest fixed cost a planning session + carries, so the gate is category-priced: + - Compact-plan categories default to `freshness: accept`: plan on the + current graph with source verification weighted higher — their plans + cite little graph evidence. Escalate to a refresh mid-plan only when a + graph claim becomes load-bearing (e.g. Proposed Changes rest on a d=1 + dependent list), and only then. + - Full-plan categories default to `freshness: strict`, and under it: + - **Analyzer provenance check — before any refresh.** Compare the resolved + runner identity with the index metadata and, in an analyzer-source + checkout, with current analyzer source. If identity is stale or unknown, + do not build output and do not make that graph load-bearing. Record a + **stale analyzer provenance — source-weighted limitation** in + `index_refresh`, the plan header, and §12; rely on targeted source reads + or hand execution to `gitnexus-work`, which owns the build-current gate. + - Stale index → run `analyze --index-only` via the resolved runner + (append `--pdg` when the task category will reach Phase 3) and re-read + the context resource **only when runner provenance is known-current**. + Refresh budget, stated once here: at most one `--index-only` refresh in + Phase 1 **plus** at most one later `--pdg` upgrade in Phase 3 (only when + Phase 1's refresh lacked `--pdg`) per planning session — a Deepen run is + its own session. Record each command, runner identity, and outcome in the + ledger's `index_refresh`. + - Refresh failed or impractical (no write access to the index, prohibitive + repo size), or `freshness: accept` was passed → proceed on the stale + graph, weight source verification higher, and state the staleness and + the skipped refresh in the plan header and Assumptions. + - Resources unreadable but tools working → proceed on tools alone, treat + freshness as unknown (weight source higher), and note it in the plan. + - GitNexus unavailable entirely → switch to **Fallback mode** (below). +5. For architecture-scale tasks only, also read + `gitnexus://repo/{name}/clusters` and `.../processes`. + +## Phase 2 — Graph navigation ladder + +Use the narrowest operation that answers the current ledger question, in this +order. Budgets: at most `max_primary_symbols` (5) primary symbols and +`max_related_symbols` (20) related symbols active in the ledger. + +1. `query {search_query, task_context}` — locate concepts, execution flows, + modules, and related tests for the task. +2. `context {name}` — 360° view of each candidate primary symbol: callers, + callees, categorized refs, processes. Promote to primary or discard. An + `ambiguous` result (ranked candidates) is answered by one retry narrowed + with `kind` / `file_path` / uid — that retry is an allowed repeat. +3. `impact {target, direction}` — upstream/downstream blast radius for shared + or high-connectivity symbols (`maxDepth` = `impact_depth`; `summaryOnly: +true` first for hub symbols, then drill in — an allowed repeat). Record the + d=1 items — the **direct (depth-1) dependents** — the plan must account + for every one of them. +4. `trace {from, to}` — when the task hinges on _how A reaches B_, one call + instead of chained context hops. +5. Statement-level PDG — Phase 3, for the functions the change centers on. +6. `cypher` — last resort, only for a precise graph question the tools above + cannot express. Read `gitnexus://repo/{name}/schema` first; anchor and + LIMIT every query. +7. `detect_changes {scope}` — only when planning against existing uncommitted + or branch work. + +Do not run every tool by default. A local test fix may finish the ladder at +step 2. + +## Phase 3 — Statement-level PDG slice + +For the 1–3 functions most central to the change, build a bounded **PDG +context slice**. Read `references/pdg-slice.md` and follow it — it owns the +tool calls, inclusion criteria, depth bounds, slice schema, the security and +performance modes, and the no-PDG-layer fallback. + +## Phase 4 — Targeted source verification + +GitNexus said where to look; now confirm what is there. Using ordinary file +reads (exact line ranges, not whole files unless genuinely required): + +- Read every source range the plan will cite: signatures, branch conditions, + state mutations, error paths, nearby comments that change behavior. Compact + plans cite less — verify what they cite, don't expand the citation set to + have more to verify. +- Read the tests GitNexus associated with the primary symbols; never claim a + test exists without having located it. +- Verify the build/test commands the plan will name actually exist + (package.json scripts / CI workflows), and prefer the script form that + carries its prerequisites (pre-hooks) over invoking underlying binaries + directly. +- Check repo conventions that constrain the change (AGENTS.md, GUARDRAILS.md, + lint/build config) — only the parts the change touches. +- Mark each ledger symbol `source_verified: true` as you go. **A symbol that + is named in Proposed Changes must be source-verified.** +- On graph/source disagreement: trust source, record the discrepancy in the + ledger and the plan, recommend re-indexing. Never present stale graph data + as fact. +- Immediately before composition, recompute the versioned + `evidence_provenance` snapshot by invoking + `scripts/evidence-provenance.mjs` exactly as specified in + `references/evidence-provenance.md`: the + canonical global dirty digest over all dirty paths and the sorted manifest + of every cited path, including object kind and + HEAD/index/worktree/untracked layer digests. Re-read any citation that + changed during planning. Exclude only the generated plan path. + +Evidence hierarchy, strongest first: current source and config → current tests +and executable behavior → compiler/build/lint output → GitNexus graph and PDG +→ documentation and comments. + +## Phase 5 — Compose the plan + +1. Read `references/plan-template.md` and fill the category's form — compact + (core sections, ≤80 lines excluding the pack) or full (all 13 sections) — + from the ledger, tagging claims with the template's four classes — + `[verified]`, `[graph]`, `[inferred]`, `[assumed]` — and routing open + questions to §12. +2. Build the implementation context pack per `references/context-pack.md` + (this is section 11 of the plan), including mandatory + `evidence_provenance` in compact and full forms. +3. Set `generated_plan_path` to + `docs/plans/YYYY-MM-DD-gitnexus-plan-<slug>.md` under the root of the repo + being planned (the Phase 1 target repo, not necessarily the cwd); use a + 3–5-word kebab-case slug and repo-relative paths inside the document. + Compose the complete document without creating that destination, then + pipe its exact UTF-8 bytes to `scripts/evidence-provenance.mjs write-plan` + as specified in `references/evidence-provenance.md`. The helper safely + creates missing parent directories. Initial planning must not pass + `--replace`. A safe-write failure blocks plan publication: report it and + do not write directly, choose an external destination, or weaken the + repo-relative provenance contract. The snapshot and writer commands apply + the same strict generated-plan filename/date validator; do not substitute a + source, `.git`, or arbitrary `docs/plans/` path in either invocation. +4. Present in chat: objective, proposed-changes summary, implementation + sequence, top risks, open questions, and the plan file path. Do not paste + the whole document into chat. + +## Deepen mode + +`/gitnexus-plan deepen <plan-path>` strengthens an existing plan in place +instead of creating a new one: + +1. Resolve the target repository and normalized repo-relative plan candidate, + then load it with `scripts/evidence-provenance.mjs read-plan --repo <root> +--generated-plan <candidate>` exactly as specified in + `references/evidence-provenance.md`. Reject a missing, external, escaping, + symlinked, or differently scoped path. Decode and parse only the receipt's + exact `plan_bytes_base64`; retain its canonical `generated_plan_path` and + `plan_digest` unchanged for the entire Deepen session. +2. Re-run Phase 1 in full — analyzer provenance check and freshness gate (a + Deepen run is its own session, with its own refresh budget). +3. **Re-anchor before re-pinning.** Recompute the plan's global dirty digest + and cited-path manifest as well as comparing its old HEAD pin with current + HEAD. Changed, renamed, deleted, mixed, or newly absent cited paths get + their ranges re-read — or the claim downgraded — _before_ the pin and + provenance snapshot move. Moving only the commit pin silently launders + dirty or stale claims as verified. +4. Escalate to `depth: deep` (impact_depth 3, clusters/processes read) + unless the invocation overrides knobs explicitly. +5. Seed the ledger from the plan's §11 pack, then re-verify: every + `[graph]`/`[inferred]` claim gets a targeted pass toward `[verified]`; + every `[assumed]` claim is resolved or kept with its reason; direct + (d=1) dependent accounting is re-checked against the refreshed graph; + PDG slices are built or expanded for the central functions when the + layer is present. +6. **Reconcile execution state.** If `gitnexus-work` already landed commits + for this plan (a mid-execution route-back), mark the §7 steps present at + HEAD as completed and re-sequence the remainder — the rewritten plan must + be executable from the top without redoing landed steps. +7. Strengthen whatever the deeper pass showed thin — test scenarios, risks, + Definition of Done — and carry claim-tag upgrades through the prose. +8. Rewrite the **same canonical file** through + `scripts/evidence-provenance.mjs write-plan --replace +--expected-plan-path <retained-read-plan-path> +--expected-plan-digest <retained-read-plan-digest>`: same 13 sections, + context pack kept in sync, evidence header updated. `--replace` is reserved + for Deepen mode, and both expected values must come from the same read-plan + receipt; any digest/path mismatch blocks publication. Retain the successful receipt's + `prior_plan_backup_git_path`; it names the verified Git-admin backup of the + displaced plan. Summarize the delta in chat: claims upgraded, claims that + failed re-verification, sections changed, and that backup path. + +## Configuration + +Baseline defaults — the Phase 0 category posture overrides them, and inline +`key:value` tokens before the task text override both (the repo has no +skill-config file mechanism; invocation args are the mechanism): + +| Knob | Default | Meaning | +| --------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| `depth` | by category | `narrow` = `impact_depth` 1, PDG only if one function is clearly central; `default` = this table; `deep` = `impact_depth` 3 + clusters/processes read | +| `form` | by category | `compact` (core sections + mini-pack, ≤80 lines excl. pack — see `references/plan-template.md`) or `full` (all 13 sections) | +| `impact_depth` | 2 | `maxDepth` for `impact` | +| `pdg_data_depth` | 2 | Data-dependence hops in the PDG slice | +| `pdg_control_depth` | 2 | Control-dependence hops in the PDG slice | +| `max_primary_symbols` | 5 | Ledger budget (active symbols; discards don't count) | +| `max_related_symbols` | 20 | Ledger budget (active symbols; discards don't count) | +| `max_snippet_lines` | 30 | Longest source excerpt quoted in the plan | +| `freshness` | by category | `strict` (full-plan categories) = refresh a stale index (and a missing PDG layer) with `analyze --index-only [--pdg]` before relying on the graph; `accept` (compact categories) = plan on the current graph, source-weighted and labelled, refreshing only if a graph claim becomes load-bearing | + +## Fallback mode (GitNexus or PDG unavailable) + +1.

Schema 1 is legacy and deliberately +rejected, so the executor must conservatively re-anchor it under schema 2. + +After the snapshot is in the fully composed document, publish its exact UTF-8 +bytes through the same helper: + +```bash +node <skill-dir>/scripts/evidence-provenance.mjs write-plan \ + --repo "$PWD" \ + --generated-plan docs/plans/YYYY-MM-DD-gitnexus-plan-example-change-plan.md \ + < /path/to/outside-repo-scratch-plan.md +``` + +For Deepen only: + +```bash +node <skill-dir>/scripts/evidence-provenance.mjs write-plan \ + --repo "$PWD" \ + --generated-plan docs/plans/YYYY-MM-DD-gitnexus-plan-example-change-plan.md \ + --replace \ + --expected-plan-path docs/plans/YYYY-MM-DD-gitnexus-plan-example-change-plan.md \ + --expected-plan-digest 'sha256:<digest-from-read-plan>' \ + < /path/to/outside-repo-scratch-plan.md +``` + +Initial planning never passes `--replace`; an existing destination is an +error. Deepen mode rewrites the same path by adding `--replace`, +`--expected-plan-path <generated_plan_path-from-read-plan>`, and +`--expected-plan-digest <plan_digest-from-that-same-receipt>`. Standard input must be +valid UTF-8 and at most 16 MiB. A successful write prints a JSON receipt with +the normalized `generated_plan_path` and `bytes_written`. A successful Deepen +write also returns `prior_plan_backup_git_path`, a durable Git-admin path for +the displaced plan. The CLI rejects every option that does not apply to its +selected command; the direct API likewise requires literal booleans and exact +digest strings rather than truthy coercion. + +## Path contract + +Every Git path and CLI path must be valid UTF-8, already normalized to Unicode +NFC, and a nonempty POSIX repo-relative path. NUL, backslash, absolute/drive +paths, empty components, and `.` or `..` components are rejected. The helper +does not silently repair or alias them. Invalid UTF-8 from Git, non-NFC names, +unmerged index stages, unsupported Git modes, sockets/devices/FIFOs, unreadable +objects, symlink traversal in a parent path component, or a repository mutation +observed during the snapshot fail closed. + +The generated-plan path is always repo-relative under schema 2. Snapshot +exclusion and writing require exactly +`docs/plans/YYYY-MM-DD-gitnexus-plan-<3-5-word-kebab-slug>.md`, including a +valid calendar date; they cannot target `.git`, source, configuration, or an +arbitrary repo file. For compatibility with documented and legacy plans, +`read-plan` accepts normalized files matching `docs/plans/*gitnexus-plan*.md`, +while retaining the same descriptor-anchored containment checks. That read +compatibility does not widen the writer. External output has no schema-2 +representation. The snapshot exclusion is one exact normalized path +comparison. No glob, directory, basename, or `docs/plans/`-wide exclusion is +permitted. If the exact path is a rename endpoint, only that endpoint record is +excluded. + +## Safe existing-plan read contract + +`read-plan` fails closed unless Linux `/proc/self/fd`, `O_DIRECTORY`, and +`O_NOFOLLOW` are available. It resolves the exact Git top-level, opens the +repository root and every plan parent as held no-follow directory descriptors, +rejects missing, symlink, non-directory, and escaping parents, and opens the +leaf with `O_NOFOLLOW`. It reads at most 16 MiB from that held file descriptor, +requires valid UTF-8, hashes the exact bytes, then proves both the parent chain +and lexical leaf still name the same held objects before returning its receipt. +Neither Deepen nor work may parse bytes obtained before or outside this receipt. + +## Safe generated-plan write contract + +The writer fails closed unless Linux `/proc/self/fd`, `O_DIRECTORY`, +`O_NOFOLLOW`, and Python 3 with libc `renameat2(RENAME_NOREPLACE)` support are +available. Python may live in `/usr/local`, a Nix profile, or another absolute +PATH directory, but the helper accepts only a resolved executable and +containing directory owned by root or the current user and not writable by +group/other. The resolved executable is opened without following links and +invoked through that held descriptor. Relative PATH entries are ignored. The plan parent and the +repository's Git-admin directory must also share a filesystem. It resolves +the target repository's exact Git top-level, opens that root and every +destination parent as held no-follow directory descriptors, creates missing +parents relative to those descriptors, and proves the descriptor and lexical +chains still identify the same directories at the write boundary. A symlink +or non-directory parent, an escaping resolved path, a symlink/non-regular final +target, or a parent swap is an error. + +The writer creates a random exclusive temporary file relative to the held final +parent descriptor and keeps its no-follow descriptor open. It writes and +flushes the bytes, binds the temporary name to the opened inode, and hashes the +open file before publication. Immediately before publication it revalidates +the parent and the temporary path, inode, size, and digest. Publication uses an +atomic no-replace move relative to the held directory descriptor. Initial mode +therefore cannot overwrite a destination that appears after the absent check. +The writer then flushes the directory and revalidates the committed path by +opening it with `O_NOFOLLOW`, hashing both the original temporary fd and the +path-bound fd, and performing a second descriptor-anchored path identity check +after hashing. A detected mutation or replacement aborts instead of accepting +mixed-era output. + +`--replace` accepts only a pre-existing regular file and is reserved for +Deepen; without it, accidental overwrite is rejected. It also requires the +exact canonical `generated_plan_path` and `plan_digest` from the same session's +`read-plan` receipt. The expected path must exactly equal the write +destination, so identical bytes from one plan cannot authorize another plan. +Immediately before +preservation, the writer hashes the still-held prior-plan fd and rejects any +digest, inode, or path mismatch, including same-inode edits and changes between +read and write. It then atomically moves the current destination without +replacement to a random `gitnexus-plan-backups/` file under the resolved +Git-admin directory and verifies the moved inode and digest against that held +fd. Only then does it publish the new plan with the same atomic no-replace +primitive. A destination that reappears at either boundary is left untouched. + +Every newly created plan or vault directory is fsynced and then fsynced into +its containing directory. Every cross-directory preservation move fsyncs both +its source and destination directories before success or a recovery path is +reported. After temporary bytes exist, a failed publication or verification preserves +every available prior, displaced, unpublished, or intended plan in that +Git-admin vault before reporting failure. Each reported recovery is reopened +from a freshly resolved Git root and verified before the error names it as +`git-path:gitnexus-plan-backups/<random-name>`. Resolve that value with +`git rev-parse --git-path gitnexus-plan-backups/<random-name>`; never interpret +it as a repo-relative working-tree path. This remains valid if the held plan +parent was renamed after publication. The writer never reports recovery +through a stale lexical parent and never performs an identity-check-then-unlink +rollback that could delete a racer's replacement. Read-only or unsupported +checkouts produce a blocking error. Callers must not bypass the helper, +redirect to an external path, or weaken these checks. + +## Canonical bytes + +The `global_dirty_digest.value` is lowercase SHA-256 (without a `sha256:` +prefix) over this byte stream. All textual values are their exact UTF-8 bytes. +`NUL` below is one `0x00` byte. + +1. Prefix fields, each followed by NUL, then one additional NUL: + `gitnexus-evidence-provenance`, `schema_version`, `2`. +2. Zero or more records sorted by unsigned lexicographic comparison of the + normalized path's UTF-8 bytes. Locale and filesystem order are forbidden. +3. Each record is `record` + NUL, then the following fixed-order sequence of + `field-name` + NUL + `field-value` + NUL pairs, then one additional NUL: + `path`, `state`, `head_kind`, `index_kind`, `worktree_kind`, + `untracked_kind`, `rename_from`, `rename_to`, `head_digest`, + `index_digest`, `worktree_digest`, `untracked_digest`. +4. The literal `absent` represents every unavailable rename endpoint, object + kind, and layer digest in canonical bytes. It is never an empty string. + +The schema's canonicalization literal is exactly +`gitnexus-evidence-provenance-v2 NUL-framed UTF-8 records`. The fixed field +count plus the extra NUL after prefix/record makes framing unambiguous; values +cannot contain NUL. Duplicate normalized paths are rejected. + +## Records, renames, and states + +The raw dirty set comes from Git porcelain v2 with NUL termination, all +untracked files, submodule inspection enabled, a fixed 50% rename threshold, +and both `diff.renameLimit=0` and `status.renameLimit=0`, so repository config +cannot cap rename candidates. Raw porcelain facts that share a path are merged +into one canonical record. A rename contributes two endpoint facts: + +- old endpoint: `path=<old>`, `rename_from=absent`, `rename_to=<new>`; +- new endpoint: `path=<new>`, `rename_from=<old>`, `rename_to=absent`. + +Both normally have state `renamed`; record sorting, not old/new role, +determines order. A worktree-dirty rename destination or any endpoint that also +has another fact is `mixed`, with rename metadata retained. When either endpoint +is cited, the cited manifest expands to include both. + +Ordinary `XY` status maps to `mixed` when index and worktree columns are both +dirty, otherwise `deleted` for a deletion, `staged` for index-only change, and +`unstaged` for worktree-only change. `?` is `untracked`. Multiple distinct +facts for the same path become `mixed`; a staged deletion plus a recreated file +therefore retains HEAD/index facts while the filesystem object is recorded in +the untracked layer. `? child/` is Git's embedded-directory marker: the trailing +slash is removed before path normalization and `child` is materialized as one +bounded directory object. A cited path outside the dirty set is `clean`, +`untracked` when it exists only outside Git layers, or `absent` when no layer +exists. + +## Object and digest rules + +Every present layer digest is `sha256:<lowercase-hex>`: + +- HEAD regular/symlink: SHA-256 of the exact Git blob bytes. HEAD directory: + SHA-256 of the exact raw Git tree bytes. HEAD gitlink: SHA-256 of the ASCII + object ID stored by the tree. +- Index regular/symlink: SHA-256 of the stage-0 Git blob bytes. Index gitlink: + SHA-256 of its ASCII object ID. The index has no directory layer. Any + non-stage-0 entry is rejected. +- Tracked worktree regular: raw file bytes, opened without following symlinks. + Symlink: raw link-target bytes. Gitlink: ASCII object ID at the checked-out + nested HEAD, but only after `rev-parse --show-toplevel` proves that the + directory itself is the nested repository root, `HEAD` resolves there, and + porcelain v2 reports no staged, unstaged, untracked, or ignored nested changes. The + same root, HEAD, and clean-status proof is repeated by the mutation guard. A + dirty, empty, uninitialized, or parent-falling-through gitlink fails closed. + Directory: the v1 directory stream described below. +- A path absent from both HEAD and index places the filesystem object in the + `untracked` layer and marks `worktree` absent. A Git-backed path places it in + `worktree` and marks `untracked` absent. A missing layer uses literal + `absent` for both kind and digest; an empty file is the SHA-256 of zero bytes. + +Filesystem directory bytes use prefix fields +`gitnexus-evidence-directory`, `schema_version`, `1`, the same NUL framing, +and recursive entries sorted by unsigned UTF-8 relative-path bytes. Each entry +has fixed fields `path`, `kind`, `digest`. A single bottom-up filesystem walk +visits each node once and returns each child digest plus the flattened subtree +needed to preserve those canonical bytes; links are never followed. When the +directory is proven to be an exact nested Git top-level, only its administrative +`.git` entry is excluded. Every other child, including working files and nested +directories, remains evidence. + +Each directory object is bounded to 10,000 visited entries, depth 256, and 256 +MiB of regular-file content. Exceeding a bound fails closed. These bounds apply +independently to each top-level directory object materialized by a record. + +HEAD objects are read only from the full object ID captured at snapshot start; +the symbolic `HEAD` name is never re-resolved for layers. Index layers are +parsed from one captured stage-0 listing. The helper guards the corresponding +HEAD/ref/reflog controls and raw index file, compares the captured listing at +the end, and rejects ordinary A-to-B-to-A mutations instead of accepting +mixed-era layers. + +Regular files are read through an `O_NOFOLLOW` descriptor with before/after +identity checks. Symlinks use lstat/readlink/lstat; directories record identity +before and after their inventory. The helper also compares raw porcelain-v2 +status and HEAD at the start and end, then rechecks filesystem guards. An +absent cited path holds a no-follow descriptor for the nearest existing parent +and records the first missing component or leaf; that anchored absence is +checked both before and after the final Git status pass, so a newly created +ignored path cannot evade porcelain. Any observed race rejects the snapshot +rather than emitting mixed-era evidence. diff --git a/gitnexus-claude-plugin/skills/gitnexus-plan/references/pdg-slice.md b/gitnexus-claude-plugin/skills/gitnexus-plan/references/pdg-slice.md new file mode 100644 index 000000000..d6b3da201 --- /dev/null +++ b/gitnexus-claude-plugin/skills/gitnexus-plan/references/pdg-slice.md @@ -0,0 +1,109 @@ +# Building the PDG context slice + +Statement-level evidence for the 1–3 functions most central to the change. +Goal: a compact slice the planning LLM can hold, never a graph dump. + +## Tools (all verified against `gitnexus/src/mcp/tools.ts`) + +| Question | Call | +| --- | --- | +| Under what condition does X run?

If stale, run +`node .gitnexus/run.cjs analyze --index-only` before trusting graph results +(temporary worktrees never carry the gitignored `run.cjs` — fall back to the +installed `gitnexus` CLI, then `npx gitnexus`), and include `--pdg` in that +same refresh when the diff plausibly touches trust or data-flow boundaries, +so the taint pass below doesn't pay a second full analyze. Taint and +dependence evidence needs that PDG layer: when the workflow's taint pass +finds it missing, rebuild with `analyze --pdg --index-only` and record the +rebuild in provenance. For local changes, refresh the index so new or +modified source is represented. +If an exact target checkout/index cannot be established, state the limitation +and do not claim a complete graph-backed review. + +## Review workflow + +1. Read the full diff and changed-file list. Separate generated files, + dependency churn, tests, and behavior changes. +2. Run `detect_changes` against the exact surface: + - PR/branch/`...`: `scope: "compare"`, `base_ref: <merge-base SHA>`. + - Explicit `A..B`: `scope: "compare"`, `base_ref: <A SHA>` from a worktree + at `B`. + - Local: `scope: "staged"`, `"unstaged"`, or `"all"`. + Pass `worktree` when the MCP server is attached elsewhere. +3. Run upstream `impact` with `includeTests: true` for each behaviorally changed + symbol. Prioritize public contracts, shared types, control flow, persistence, + security boundaries, and error handling; skip mechanical/generated changes. +4. Inspect every direct (`d=1`) dependent that is outside the diff. A dependent + outside the diff is a lead, not automatically a bug—verify the changed + contract and caller behavior in source. +5. Use `context` on key or ambiguous symbols and inspect affected execution + flows. Read the surrounding implementation and tests at cited locations. +6. **Taint and dependence pass.** For changed code on trust or data-flow + boundaries — external input, persistence, process execution, network, + auth — run `explain` on the changed files or symbols and judge its + source→sink taint findings against the diff: a flow the change + introduces, or a sanitizer/guard the change removes, is a finding; a + pre-existing flow is context, not a defect of this change. When the + change claims to guard or sanitize something, verify with `pdg_query`: + what controls the changed statement, and where its values flow. This + needs a `--pdg` index; if one cannot be built, state that the taint pass + was skipped rather than implying coverage. +7. Check whether tests exercise the changed behavior, boundary conditions, and + affected flows. Run focused read-only validation when practical. When the + diff refreshes a committed baseline, fingerprint, or golden, re-run the + exact CI check command against the head instead of trusting the committed + value — a stale artifact is invisible in the diff and fails only in CI. +8. Reconcile graph evidence with the raw diff. New files, dynamic dispatch, + configuration, reflection, and untracked content may require direct review + even when graph results are empty. Version and invalidation constants are + review surface: when the diff changes what gets emitted or persisted, + verify every schema/version constant gating caches, incremental + writebacks, and fingerprint baselines was bumped or regenerated — in + GitNexus itself, for example: `INCREMENTAL_SCHEMA_VERSION` (the + incremental write set covers only changed files, so new cross-file edges + never reach an existing index without the bump), the parse-store + `SCHEMA_BUMP`, and both bench fingerprint sets. + +## Expert lenses + +Depth comes from matching reviewers to what actually changed, not from one +generalist pass. After workflow step 2, group the changed files and symbols +by the functional areas the graph already knows — the index's cluster +listing; `context` names each symbol's cluster — and give each touched area +an expert lens: a reviewer charged with that domain's contracts, invariants, +and failure modes, grounded in the repo's own material (architecture docs, +agent rules, the domain's tests) before judging the diff. A lens verifies, +not just reads: when the changed code is a pure function reachable from the +repo's own toolchain — parsers, extractors, capture emitters, formatters — +execute it on the candidate failing shape (a scratch probe, deleted +afterward) and cite the observed output. An empirical probe outranks source +reading in the evidence hierarchy; role swaps, dead branches, and +error-recovery-dependent behavior repeatedly pass a reading and fail a +ten-line probe. The numbered +workflow runs exactly once; dispatch the lens passes after step 6, handing +each lens the evidence already collected rather than letting lenses repeat +the `impact`, `context`, or taint calls. In GitNexus +itself, for example: shared ingestion-pipeline changes get an ingestion +expert plus one language expert per changed language extractor; embeddings +changes an embeddings expert; LadybugDB/storage changes a Ladybug expert. + +Four cross-cutting lenses run regardless of domain: + +- **Architectural fit** — the change lands where the architecture says the + concern lives, reuses existing seams, and adds no parallel structure. +- **Language conformance** — the repo's own type/lint/test contract as + configured (tsconfig strictness, lint rules, test conventions); in a + strict TypeScript repo, for example: strictness intact, no `any`/`as any` + escapes, module boundaries typed. Judge by the repo's contract, never a + universal style bar. +- **Definition of Done** — changed behavior has tests, docs the change makes + stale are updated, and sync/drift guards (shipped copies, manifests, + changelogs) still hold. +- **Simplicity** — YAGNI and clear-code check: flag speculative abstraction, + unused knobs, and overengineering; the smallest diff that meets the + Definition of Done is the standard. + +Scale effort to the surface: a single-domain change of a few files gets one +combined pass covering its domain lens plus the four cross-cutting checks; +a multi-domain change gets one lens per touched area — run as parallel +subagents where the harness supports them, each scoped to its own files +plus the shared graph evidence, and as sequential passes otherwise. Never +spawn a lens for a domain the diff does not touch. Merge lenses that ground +in the same material — two lenses reading the same files pay twice for one +read's coverage, so give one reviewer both charges. Where the harness +offers model or effort tiers, run mechanical lenses (rename sweeps, +doc-consistency checks) on a cheaper tier and reserve the strongest engine +for adversarial judgment. Every lens reports +through the Finding standard below; merge and dedup before the verdict, +dropping anything without a concrete failing scenario. + +## Finding standard + +Report a finding only when the reviewed change introduces a concrete defect, +regression, security issue, compatibility break, material coverage gap, or a +maintainability cost with a concrete carrying scenario (a dead knob, a +duplicated contract, a drift-prone copy). +Each finding must include: + +- severity and a precise `path:line` anchor; +- the failing scenario or contract; +- GitNexus evidence (dependent symbol/process) when applicable; +- why existing code or tests do not mitigate it; +- a concise remediation or missing test. + +Do not report style preferences, pre-existing issues, raw risk counts, or +speculation as defects.

Read + `references/evidence-provenance.md`, then invoke this skill's + `scripts/evidence-provenance.mjs` with the plan's exact + `generated_plan_path`, every cited manifest path, and schema version 2. + Never recreate its bytes in shell or prose.

Honor the generated-plan exclusion exactly; do not + exclude all plans. +4. **Re-anchor on either mismatch.** Missing or legacy provenance, a HEAD + mismatch, or a global dirty digest mismatch requires a conservative + re-anchor before work: + - Diff every cited-path manifest entry. Changed cited paths — including + staged-only, unstaged-only, deleted, both rename endpoints, mixed + staged+unstaged, and disappeared untracked paths — get their cited ranges + re-read before reliance. + - Compare the current whole-tree dirty set with the pinned global digest. + New uncited dirty paths get a scope assessment: determine whether they + overlap the plan, requirements, tests, or a key technical decision; do not + silently ignore them merely because they are uncited. + - Unreadable or unclassifiable cited evidence blocks every dependent step + until it can be restored, read, or resolved with the user. Never substitute + an invented digest or treat absence as an empty file. + - Keep the re-anchor result in session state; never mutate the plan body. + Use Deepen only if reconciliation invalidates scope, requirements, a key + technical decision (KTD), or the planned implementation seam. Ordinary + byte drift that leaves those decisions valid is re-verified locally. +5. **Re-verify `assumptions` cheaply** (each one names what to check). + A failed assumption is a stop-and-replan signal for the steps that + depend on it, not something to code around silently. +6. Note `open_questions` — if one blocks a step and the answer materially + changes the work, ask the user before that step, not after. +7. **Pre-completed check.** If commits for this plan already exist on the + branch (a prior partial run, or a post-route-back Deepen cycle), verify + which §7 steps have landed at HEAD: those are skipped and reported as + pre-completed, and execution resumes at the first unlanded step. All + steps landed → report that and stop. + +## Phase 2 — Environment + +- On the default branch → create a feature branch named from the plan slug. + On a feature branch already → stay only if it is meaningful _for this + plan_ (name matches the plan slug, or the user confirms); otherwise + branch from here with the slug name. +- If the plan document is not yet committed, commit it now + (`docs(plans): add <slug> plan`) — the plan travels with the work it + drives, and the final review diff then includes it. +- Confirm the `verification_commands` from the pack actually run in this + checkout (dependencies installed, builds present) before starting, not + after the last step. + +### Build-current/index-current procedure + +This is the single graph-freshness procedure owned by `gitnexus-work`; it +applies in plan mode and direct mode. Before every graph-dependent `impact` +query, run the Build-current/index-current procedure. Before final graph +verification, run the same Build-current/index-current procedure again. + +1. Capture current HEAD and working-tree provenance. Read + `gitnexus://repo/<name>/context` and use its typed `index.commit` and + `index.runner_identity` receipt — never infer analyzer identity from prose, + timestamps, or a path alone. Compare `index.commit` with current HEAD. A + current receipt has `schemaVersion: 4`, resolved runtime path/version, CLI + version, invoked-artifact path/digest, build + kind/root/canonicalization/digest, and dependency-runtime + manifest/lockfile/canonicalization/package-count/artifact-count/digest. Its + dependency canonicalization is + `gitnexus-analyzer-dependency-runtime-v4`. The dependency-runtime digest + covers resolved package metadata and complete loadable package payloads, + including JavaScript, JSON, native, Wasm, and parser artifacts; schema-1, + schema-2, and schema-3 receipts are legacy/stale (the MCP context labels + them `runner_identity_schema_status: legacy-or-unknown`). Require MCP + `index.incomplete_reasons: []`. Run the exact candidate CLI's + `status --json` command and require `index.runnerIdentityStatus: current`, + `index.incompleteReasons: []`, and top-level `status: up-to-date`. The + status comparator checks every semantic field while deliberately excluding + only diagnostic `invokedArtifact`; a worker-authored persisted receipt and + the CLI's live receipt may therefore differ in that field without becoming + stale. Missing, malformed, differently versioned, semantically unequal, or + incomplete receipts are unknown/stale, not a match. +2. Relationship-affecting committed and uncommitted edits invalidate + freshness after the last successful procedure run. This includes staged, + unstaged, untracked, deleted, or renamed analyzer/source/config changes + that can alter symbols or edges. Any such edit between steps requires an + inter-step refresh before the next graph query, even when HEAD did not move. +3. If the typed runner receipt is stale or unknown in an analyzer-source + checkout, build current local source using the verified package script. In + this repo: `cd gitnexus && npm run build`. Resolve the package's `bin` + target and run that exact artifact's `status --json` command to capture its + current receipt. Source/build timestamps are a conservative rebuild + trigger, not proof that an artifact is current. +4. Invoke that exact freshly built local CLI from the target repo root with + PDG layers enabled. In this repo: + `node gitnexus/dist/cli/index.js analyze --index-only --pdg`. + Add `--force` when the persisted receipt was absent, malformed, + differently versioned, or unequal so an already-up-to-date fast path cannot + leave legacy/stale provenance in place. The usual project-runner form, + `node .gitnexus/run.cjs analyze`, is acceptable only when its proven runner + identity resolves to that same freshly built artifact. Do not fall back to + an older project runner, global install, or package download after + resolving/building the local artifact. +5. Re-read index context, rerun the exact invoked CLI's `status --json`, and + prove the post-refresh `index.commit` equals current HEAD, MCP + `index.incomplete_reasons` is empty, and its complete + `index.runner_identity` equals status `index.runnerIdentity` (the persisted + receipt). Require status `index.runnerIdentityStatus: current`, empty + `index.incompleteReasons`, and top-level `status: up-to-date`; do not require + raw equality with `current.runnerIdentity` because `invokedArtifact` is a + diagnostic entrypoint deliberately excluded from semantic freshness. + Record the dirty-state digest indexed in this procedure so same-HEAD + uncommitted edits can invalidate it later. +6. Any build, refresh, metadata-read, or identity-verification failure blocks + graph-dependent impact work and final completion. Report the failing + command and evidence; do not continue on an older graph. + +## Phase 3 — Execute the Implementation Sequence + +Work through plan §7 step by step, in order. For each step: + +1. **Fresh impact before editing.** Run the Build-current/index-current + procedure immediately before every graph-dependent + `impact {target, direction: "upstream"}` query. Then account for every + direct (d=1) dependent. HIGH or CRITICAL risk → surface it to the user + with the blast radius before proceeding (repo mandate — see AGENTS.md + GitNexus rules). +2. **Honor the constraints.** `pdg_constraints` entries state ordering and + dependence facts the change must preserve; `avoid` entries are hard + prohibitions; `architectural_patterns` name the shape to mirror (read the + example location before inventing one). +3. **Implement minimally.** The smallest change that completes the step, + following the surrounding code's conventions. +4. **Test from the plan's scenarios.** Each `tests[]` scenario (input → + action → expected outcome) becomes a real test in the named file. Add + coverage the plan missed if the step's behavior demands it; never delete + or weaken an assertion to make a step pass. Prove a new regression test + discriminates: when the failure mode is subtle, run it once against the + pre-fix tree (write the test before the fix, or stash the fix) and watch + it fail — a test that passes both ways pins nothing. +5. **Verify.** Run the step-relevant `verification_commands` (they carry + their build prerequisites; use them as written). If any part of the + change executes from build output — worker entrypoints, dist-shipped + CLIs, bundled assets — rebuild that output before every verification + run: a pass or fail against outdated build output is noise, and "the + fix doesn't work" is more often "the fix never loaded". +6. **Commit atomically.** `detect_changes {scope: "staged"}` before every + commit to confirm only the expected symbols and flows are affected + (repo mandate); then one conventional commit per step. Run stage → + `detect_changes` → commit as one unbroken sequence from the repository + root — interleaving other work between the gate and the commit is how + the gate gets skipped. Unexpected + affected flows → investigate before committing, not after. + +A relationship-affecting implementation edit or commit invalidates the +procedure's prior proof. The next step must perform the required inter-step +refresh before its impact query; final verification refreshes again after the +last edit. + +Steps are independently actionable: after any commit the tree is coherent. +If a step reveals the plan is wrong, stop that step, re-verify the affected +claims at HEAD, and either adapt (small, in-scope deviation — record it in +the commit message and final summary) or route back to `gitnexus-plan` +Deepen mode (structural miss) — with a one-line ask to the user when the +choice isn't obvious. + +## Phase 4 — Finish + +1. Run the full `verification_commands` suite once, at the end, even if + every step already passed individually. +2. Walk plan §13 (Definition of Done) and the pack's `acceptance_criteria` + item by item; anything unmet is either finished now or reported as + explicitly unmet — never silently dropped. +3. **Verify the final knowledge graph.** Before final graph verification, run + the same Build-current/index-current procedure after the last edit, even + when no commit landed or HEAD still equals the original pin. Then run + `detect_changes {scope: "all"}` (or the repo's equivalent final graph + check) against that proven-current index and account for every unexpected + symbol or flow. A procedure failure blocks completion. +4. Report: steps completed, commits made, deviations from the plan (with + why), assumptions that failed re-verification, DoD status, final indexed + commit and runner identity, and anything deferred. Test failures are + reported with their output, not smoothed over. + +## Never + +- Skip the Phase 3 gates: no symbol edit without `impact`, no commit without + `detect_changes`. +- Expand scope beyond the plan — §12's deferred follow-ups stay deferred. +- Mutate the plan body (committing the file verbatim in Phase 2 is not + mutation), weaken failing tests, or present unverified work as verified. + +## Skill feedback (GitNexus repo only) + +If this run exposed friction in this skill's own instructions — wrong or +missing guidance, a wasted tool budget, a phase that misrouted — and the repo +carries `eval/workflow_bench/`, append one JSON line to +`eval/workflow_bench/learnings.jsonl` (create the file if absent): +`{"skill": "gitnexus-work", "date": "YYYY-MM-DD", "task": "<one line>", "friction": "<one line>", "suggestion": "<one line>"}`. +Never edit this skill file itself from a live task: improvements go through +the offline candidate loop (`eval/workflow_bench/README.md` § Prompt and +skill evolution loop), where a candidate must beat the incumbent on the +paired benchmark before a human merges it. diff --git a/gitnexus-claude-plugin/skills/gitnexus-work/mcp.json b/gitnexus-claude-plugin/skills/gitnexus-work/mcp.json new file mode 100644 index 000000000..4fe6590dd --- /dev/null +++ b/gitnexus-claude-plugin/skills/gitnexus-work/mcp.json @@ -0,0 +1,8 @@ +{ + "mcpServers": { + "gitnexus": { + "command": "npx", + "args": ["-y", "gitnexus@1.6.9", "mcp"] + } + } +} diff --git a/gitnexus-claude-plugin/skills/gitnexus-work/references/evidence-provenance.md b/gitnexus-claude-plugin/skills/gitnexus-work/references/evidence-provenance.md new file mode 100644 index 000000000..c686599da --- /dev/null +++ b/gitnexus-claude-plugin/skills/gitnexus-work/references/evidence-provenance.md @@ -0,0 +1,272 @@ +# Evidence provenance serializer v2 and safe plan writer + +This file is the normative byte contract for `evidence_provenance` schema 2. +The adjacent `scripts/evidence-provenance.mjs` is its executable definition. +`gitnexus-plan` and `gitnexus-work` carry byte-identical copies so either skill +can produce the same snapshot without relying on the other skill's install. +It is also the only supported write boundary for a generated plan.

Schema 1 is legacy and deliberately +rejected, so the executor must conservatively re-anchor it under schema 2. + +After the snapshot is in the fully composed document, publish its exact UTF-8 +bytes through the same helper: + +```bash +node <skill-dir>/scripts/evidence-provenance.mjs write-plan \ + --repo "$PWD" \ + --generated-plan docs/plans/YYYY-MM-DD-gitnexus-plan-example-change-plan.md \ + < /path/to/outside-repo-scratch-plan.md +``` + +For Deepen only: + +```bash +node <skill-dir>/scripts/evidence-provenance.mjs write-plan \ + --repo "$PWD" \ + --generated-plan docs/plans/YYYY-MM-DD-gitnexus-plan-example-change-plan.md \ + --replace \ + --expected-plan-path docs/plans/YYYY-MM-DD-gitnexus-plan-example-change-plan.md \ + --expected-plan-digest 'sha256:<digest-from-read-plan>' \ + < /path/to/outside-repo-scratch-plan.md +``` + +Initial planning never passes `--replace`; an existing destination is an +error. Deepen mode rewrites the same path by adding `--replace`, +`--expected-plan-path <generated_plan_path-from-read-plan>`, and +`--expected-plan-digest <plan_digest-from-that-same-receipt>`. Standard input must be +valid UTF-8 and at most 16 MiB. A successful write prints a JSON receipt with +the normalized `generated_plan_path` and `bytes_written`. A successful Deepen +write also returns `prior_plan_backup_git_path`, a durable Git-admin path for +the displaced plan. The CLI rejects every option that does not apply to its +selected command; the direct API likewise requires literal booleans and exact +digest strings rather than truthy coercion. + +## Path contract + +Every Git path and CLI path must be valid UTF-8, already normalized to Unicode +NFC, and a nonempty POSIX repo-relative path. NUL, backslash, absolute/drive +paths, empty components, and `.` or `..` components are rejected. The helper +does not silently repair or alias them. Invalid UTF-8 from Git, non-NFC names, +unmerged index stages, unsupported Git modes, sockets/devices/FIFOs, unreadable +objects, symlink traversal in a parent path component, or a repository mutation +observed during the snapshot fail closed. + +The generated-plan path is always repo-relative under schema 2. Snapshot +exclusion and writing require exactly +`docs/plans/YYYY-MM-DD-gitnexus-plan-<3-5-word-kebab-slug>.md`, including a +valid calendar date; they cannot target `.git`, source, configuration, or an +arbitrary repo file. For compatibility with documented and legacy plans, +`read-plan` accepts normalized files matching `docs/plans/*gitnexus-plan*.md`, +while retaining the same descriptor-anchored containment checks. That read +compatibility does not widen the writer. External output has no schema-2 +representation. The snapshot exclusion is one exact normalized path +comparison. No glob, directory, basename, or `docs/plans/`-wide exclusion is +permitted. If the exact path is a rename endpoint, only that endpoint record is +excluded. + +## Safe existing-plan read contract + +`read-plan` fails closed unless Linux `/proc/self/fd`, `O_DIRECTORY`, and +`O_NOFOLLOW` are available. It resolves the exact Git top-level, opens the +repository root and every plan parent as held no-follow directory descriptors, +rejects missing, symlink, non-directory, and escaping parents, and opens the +leaf with `O_NOFOLLOW`. It reads at most 16 MiB from that held file descriptor, +requires valid UTF-8, hashes the exact bytes, then proves both the parent chain +and lexical leaf still name the same held objects before returning its receipt. +Neither Deepen nor work may parse bytes obtained before or outside this receipt. + +## Safe generated-plan write contract + +The writer fails closed unless Linux `/proc/self/fd`, `O_DIRECTORY`, +`O_NOFOLLOW`, and Python 3 with libc `renameat2(RENAME_NOREPLACE)` support are +available. Python may live in `/usr/local`, a Nix profile, or another absolute +PATH directory, but the helper accepts only a resolved executable and +containing directory owned by root or the current user and not writable by +group/other. The resolved executable is opened without following links and +invoked through that held descriptor. Relative PATH entries are ignored. The plan parent and the +repository's Git-admin directory must also share a filesystem. It resolves +the target repository's exact Git top-level, opens that root and every +destination parent as held no-follow directory descriptors, creates missing +parents relative to those descriptors, and proves the descriptor and lexical +chains still identify the same directories at the write boundary. A symlink +or non-directory parent, an escaping resolved path, a symlink/non-regular final +target, or a parent swap is an error. + +The writer creates a random exclusive temporary file relative to the held final +parent descriptor and keeps its no-follow descriptor open. It writes and +flushes the bytes, binds the temporary name to the opened inode, and hashes the +open file before publication. Immediately before publication it revalidates +the parent and the temporary path, inode, size, and digest. Publication uses an +atomic no-replace move relative to the held directory descriptor. Initial mode +therefore cannot overwrite a destination that appears after the absent check. +The writer then flushes the directory and revalidates the committed path by +opening it with `O_NOFOLLOW`, hashing both the original temporary fd and the +path-bound fd, and performing a second descriptor-anchored path identity check +after hashing. A detected mutation or replacement aborts instead of accepting +mixed-era output. + +`--replace` accepts only a pre-existing regular file and is reserved for +Deepen; without it, accidental overwrite is rejected. It also requires the +exact canonical `generated_plan_path` and `plan_digest` from the same session's +`read-plan` receipt. The expected path must exactly equal the write +destination, so identical bytes from one plan cannot authorize another plan. +Immediately before +preservation, the writer hashes the still-held prior-plan fd and rejects any +digest, inode, or path mismatch, including same-inode edits and changes between +read and write. It then atomically moves the current destination without +replacement to a random `gitnexus-plan-backups/` file under the resolved +Git-admin directory and verifies the moved inode and digest against that held +fd. Only then does it publish the new plan with the same atomic no-replace +primitive. A destination that reappears at either boundary is left untouched. + +Every newly created plan or vault directory is fsynced and then fsynced into +its containing directory. Every cross-directory preservation move fsyncs both +its source and destination directories before success or a recovery path is +reported. After temporary bytes exist, a failed publication or verification preserves +every available prior, displaced, unpublished, or intended plan in that +Git-admin vault before reporting failure. Each reported recovery is reopened +from a freshly resolved Git root and verified before the error names it as +`git-path:gitnexus-plan-backups/<random-name>`. Resolve that value with +`git rev-parse --git-path gitnexus-plan-backups/<random-name>`; never interpret +it as a repo-relative working-tree path. This remains valid if the held plan +parent was renamed after publication. The writer never reports recovery +through a stale lexical parent and never performs an identity-check-then-unlink +rollback that could delete a racer's replacement. Read-only or unsupported +checkouts produce a blocking error. Callers must not bypass the helper, +redirect to an external path, or weaken these checks. + +## Canonical bytes + +The `global_dirty_digest.value` is lowercase SHA-256 (without a `sha256:` +prefix) over this byte stream. All textual values are their exact UTF-8 bytes. +`NUL` below is one `0x00` byte. + +1. Prefix fields, each followed by NUL, then one additional NUL: + `gitnexus-evidence-provenance`, `schema_version`, `2`. +2. Zero or more records sorted by unsigned lexicographic comparison of the + normalized path's UTF-8 bytes. Locale and filesystem order are forbidden. +3. Each record is `record` + NUL, then the following fixed-order sequence of + `field-name` + NUL + `field-value` + NUL pairs, then one additional NUL: + `path`, `state`, `head_kind`, `index_kind`, `worktree_kind`, + `untracked_kind`, `rename_from`, `rename_to`, `head_digest`, + `index_digest`, `worktree_digest`, `untracked_digest`. +4. The literal `absent` represents every unavailable rename endpoint, object + kind, and layer digest in canonical bytes. It is never an empty string. + +The schema's canonicalization literal is exactly +`gitnexus-evidence-provenance-v2 NUL-framed UTF-8 records`. The fixed field +count plus the extra NUL after prefix/record makes framing unambiguous; values +cannot contain NUL. Duplicate normalized paths are rejected. + +## Records, renames, and states + +The raw dirty set comes from Git porcelain v2 with NUL termination, all +untracked files, submodule inspection enabled, a fixed 50% rename threshold, +and both `diff.renameLimit=0` and `status.renameLimit=0`, so repository config +cannot cap rename candidates. Raw porcelain facts that share a path are merged +into one canonical record. A rename contributes two endpoint facts: + +- old endpoint: `path=<old>`, `rename_from=absent`, `rename_to=<new>`; +- new endpoint: `path=<new>`, `rename_from=<old>`, `rename_to=absent`. + +Both normally have state `renamed`; record sorting, not old/new role, +determines order. A worktree-dirty rename destination or any endpoint that also +has another fact is `mixed`, with rename metadata retained. When either endpoint +is cited, the cited manifest expands to include both. + +Ordinary `XY` status maps to `mixed` when index and worktree columns are both +dirty, otherwise `deleted` for a deletion, `staged` for index-only change, and +`unstaged` for worktree-only change. `?` is `untracked`. Multiple distinct +facts for the same path become `mixed`; a staged deletion plus a recreated file +therefore retains HEAD/index facts while the filesystem object is recorded in +the untracked layer. `? child/` is Git's embedded-directory marker: the trailing +slash is removed before path normalization and `child` is materialized as one +bounded directory object. A cited path outside the dirty set is `clean`, +`untracked` when it exists only outside Git layers, or `absent` when no layer +exists. + +## Object and digest rules + +Every present layer digest is `sha256:<lowercase-hex>`: + +- HEAD regular/symlink: SHA-256 of the exact Git blob bytes. HEAD directory: + SHA-256 of the exact raw Git tree bytes. HEAD gitlink: SHA-256 of the ASCII + object ID stored by the tree. +- Index regular/symlink: SHA-256 of the stage-0 Git blob bytes. Index gitlink: + SHA-256 of its ASCII object ID. The index has no directory layer. Any + non-stage-0 entry is rejected. +- Tracked worktree regular: raw file bytes, opened without following symlinks. + Symlink: raw link-target bytes. Gitlink: ASCII object ID at the checked-out + nested HEAD, but only after `rev-parse --show-toplevel` proves that the + directory itself is the nested repository root, `HEAD` resolves there, and + porcelain v2 reports no staged, unstaged, untracked, or ignored nested changes. The + same root, HEAD, and clean-status proof is repeated by the mutation guard. A + dirty, empty, uninitialized, or parent-falling-through gitlink fails closed. + Directory: the v1 directory stream described below. +- A path absent from both HEAD and index places the filesystem object in the + `untracked` layer and marks `worktree` absent. A Git-backed path places it in + `worktree` and marks `untracked` absent. A missing layer uses literal + `absent` for both kind and digest; an empty file is the SHA-256 of zero bytes. + +Filesystem directory bytes use prefix fields +`gitnexus-evidence-directory`, `schema_version`, `1`, the same NUL framing, +and recursive entries sorted by unsigned UTF-8 relative-path bytes. Each entry +has fixed fields `path`, `kind`, `digest`. A single bottom-up filesystem walk +visits each node once and returns each child digest plus the flattened subtree +needed to preserve those canonical bytes; links are never followed. When the +directory is proven to be an exact nested Git top-level, only its administrative +`.git` entry is excluded. Every other child, including working files and nested +directories, remains evidence. + +Each directory object is bounded to 10,000 visited entries, depth 256, and 256 +MiB of regular-file content. Exceeding a bound fails closed. These bounds apply +independently to each top-level directory object materialized by a record. + +HEAD objects are read only from the full object ID captured at snapshot start; +the symbolic `HEAD` name is never re-resolved for layers. Index layers are +parsed from one captured stage-0 listing. The helper guards the corresponding +HEAD/ref/reflog controls and raw index file, compares the captured listing at +the end, and rejects ordinary A-to-B-to-A mutations instead of accepting +mixed-era layers. + +Regular files are read through an `O_NOFOLLOW` descriptor with before/after +identity checks. Symlinks use lstat/readlink/lstat; directories record identity +before and after their inventory. The helper also compares raw porcelain-v2 +status and HEAD at the start and end, then rechecks filesystem guards. An +absent cited path holds a no-follow descriptor for the nearest existing parent +and records the first missing component or leaf; that anchored absence is +checked both before and after the final Git status pass, so a newly created +ignored path cannot evade porcelain. Any observed race rejects the snapshot +rather than emitting mixed-era evidence. diff --git a/gitnexus-claude-plugin/skills/gitnexus-work/scripts/evidence-provenance.mjs b/gitnexus-claude-plugin/skills/gitnexus-work/scripts/evidence-provenance.mjs new file mode 100644 index 000000000..181d2120b --- /dev/null +++ b/gitnexus-claude-plugin/skills/gitnexus-work/scripts/evidence-provenance.mjs @@ -0,0 +1,2084 @@ +#!/usr/bin/env node + +import { createHash, randomBytes } from 'node:crypto'; +import fs from 'node:fs'; +import path from 'node:path'; +import process from 'node:process'; +import { spawnSync } from 'node:child_process'; +import { fileURLToPath } from 'node:url'; + +export const EVIDENCE_PROVENANCE_SCHEMA_VERSION = 2; +export const EVIDENCE_PROVENANCE_CANONICALIZATION = + 'gitnexus-evidence-provenance-v2 NUL-framed UTF-8 records'; + +const ABSENT = 'absent'; +const OBJECT_KINDS = new Set(['regular', 'symlink', 'gitlink', 'directory', ABSENT]); +const STATES = new Set([ + 'clean', + 'staged', + 'unstaged', + 'untracked', + 'deleted', + 'renamed', + 'mixed', + ABSENT, +]); +const RECORD_FIELDS = [ + 'path', + 'state', + 'head_kind', + 'index_kind', + 'worktree_kind', + 'untracked_kind', + 'rename_from', + 'rename_to', + 'head_digest', + 'index_digest', + 'worktree_digest', + 'untracked_digest', +]; +const UTF8_FATAL = new TextDecoder('utf-8', { fatal: true }); +const MAX_GIT_OUTPUT = 1024 * 1024 * 1024; +const MAX_PLAN_BYTES = 16 * 1024 * 1024; +const GENERATED_PLAN_READ_PATTERN = /^docs\/plans\/[^/]*gitnexus-plan[^/]*\.md$/; +const GENERATED_PLAN_WRITE_PATTERN = + /^docs\/plans\/(\d{4}-\d{2}-\d{2})-gitnexus-plan-[a-z0-9]+(?:-[a-z0-9]+){2,4}\.md$/; +export const DIRECTORY_LIMITS = Object.freeze({ + maxEntries: 10_000, + maxDepth: 256, + maxBytes: 256 * 1024 * 1024, +}); + +function sha256(bytes) { + return `sha256:${createHash('sha256').update(bytes).digest('hex')}`; +} + +function statIdentity(stat) { + return [stat.dev, stat.ino, stat.mode, stat.nlink, stat.size, stat.mtimeNs, stat.ctimeNs] + .map(String) + .join(':'); +} + +function assertStableIdentity(before, after, label) { + if (statIdentity(before) !== statIdentity(after)) { + throw new Error(`${label} changed while evidence was being read`); + } +} + +function hashFile(file, mutationGuards, directoryTraversal) { + const hash = createHash('sha256'); + const noFollow = fs.constants.O_NOFOLLOW ?? 0; + const fd = fs.openSync(file, fs.constants.O_RDONLY | noFollow); + const buffer = Buffer.allocUnsafe(1024 * 1024); + try { + const before = fs.fstatSync(fd, { bigint: true }); + if (!before.isFile()) throw new Error(`Expected a regular file at ${file}`); + if (directoryTraversal) { + directoryTraversal.bytes += before.size; + if (directoryTraversal.bytes > BigInt(DIRECTORY_LIMITS.maxBytes)) { + throw new Error(`Directory inventory exceeds ${DIRECTORY_LIMITS.maxBytes} content bytes`); + } + } + for (;;) { + const count = fs.readSync(fd, buffer, 0, buffer.length, null); + if (count === 0) break; + hash.update(buffer.subarray(0, count)); + } + const after = fs.fstatSync(fd, { bigint: true }); + assertStableIdentity(before, after, file); + mutationGuards.push({ type: 'stat', absolute: file, identity: statIdentity(after) }); + } finally { + fs.closeSync(fd); + } + return `sha256:${hash.digest('hex')}`; +} + +function git(repo, args, { allowFailure = false, input } = {}) { + const result = spawnSync('git', ['-C', repo, ...args], { + encoding: null, + env: { ...process.env, LANG: 'C', LC_ALL: 'C', GIT_OPTIONAL_LOCKS: '0' }, + input, + maxBuffer: MAX_GIT_OUTPUT, + windowsHide: true, + }); + if (result.error) throw result.error; + if (result.status !== 0 && !allowFailure) { + const stderr = Buffer.from(result.stderr ??

Taint and +dependence evidence needs that PDG layer: when the workflow's taint pass +finds it missing, rebuild with `analyze --pdg --index-only` and record the +rebuild in provenance. For local changes, refresh the index so new or +modified source is represented. +If an exact target checkout/index cannot be established, state the limitation +and do not claim a complete graph-backed review. + +## Review workflow + +1. Read the full diff and changed-file list. Separate generated files, + dependency churn, tests, and behavior changes. +2. Run `detect_changes` against the exact surface: + - PR/branch/`...`: `scope: "compare"`, `base_ref: <merge-base SHA>`. + - Explicit `A..B`: `scope: "compare"`, `base_ref: <A SHA>` from a worktree + at `B`. + - Local: `scope: "staged"`, `"unstaged"`, or `"all"`. + Pass `worktree` when the MCP server is attached elsewhere. +3. Run upstream `impact` with `includeTests: true` for each behaviorally changed + symbol. Prioritize public contracts, shared types, control flow, persistence, + security boundaries, and error handling; skip mechanical/generated changes. +4. Inspect every direct (`d=1`) dependent that is outside the diff. A dependent + outside the diff is a lead, not automatically a bug—verify the changed + contract and caller behavior in source. +5. Use `context` on key or ambiguous symbols and inspect affected execution + flows. Read the surrounding implementation and tests at cited locations. +6. **Taint and dependence pass.** For changed code on trust or data-flow + boundaries — external input, persistence, process execution, network, + auth — run `explain` on the changed files or symbols and judge its + source→sink taint findings against the diff: a flow the change + introduces, or a sanitizer/guard the change removes, is a finding; a + pre-existing flow is context, not a defect of this change. When the + change claims to guard or sanitize something, verify with `pdg_query`: + what controls the changed statement, and where its values flow. This + needs a `--pdg` index; if one cannot be built, state that the taint pass + was skipped rather than implying coverage. +7. Check whether tests exercise the changed behavior, boundary conditions, and + affected flows. Run focused read-only validation when practical. When the + diff refreshes a committed baseline, fingerprint, or golden, re-run the + exact CI check command against the head instead of trusting the committed + value — a stale artifact is invisible in the diff and fails only in CI. +8. Reconcile graph evidence with the raw diff. New files, dynamic dispatch, + configuration, reflection, and untracked content may require direct review + even when graph results are empty. Version and invalidation constants are + review surface: when the diff changes what gets emitted or persisted, + verify every schema/version constant gating caches, incremental + writebacks, and fingerprint baselines was bumped or regenerated — in + GitNexus itself, for example: `INCREMENTAL_SCHEMA_VERSION` (the + incremental write set covers only changed files, so new cross-file edges + never reach an existing index without the bump), the parse-store + `SCHEMA_BUMP`, and both bench fingerprint sets. + +## Expert lenses + +Depth comes from matching reviewers to what actually changed, not from one +generalist pass. After workflow step 2, group the changed files and symbols +by the functional areas the graph already knows — the index's cluster +listing; `context` names each symbol's cluster — and give each touched area +an expert lens: a reviewer charged with that domain's contracts, invariants, +and failure modes, grounded in the repo's own material (architecture docs, +agent rules, the domain's tests) before judging the diff. A lens verifies, +not just reads: when the changed code is a pure function reachable from the +repo's own toolchain — parsers, extractors, capture emitters, formatters — +execute it on the candidate failing shape (a scratch probe, deleted +afterward) and cite the observed output. An empirical probe outranks source +reading in the evidence hierarchy; role swaps, dead branches, and +error-recovery-dependent behavior repeatedly pass a reading and fail a +ten-line probe. The numbered +workflow runs exactly once; dispatch the lens passes after step 6, handing +each lens the evidence already collected rather than letting lenses repeat +the `impact`, `context`, or taint calls. In GitNexus +itself, for example: shared ingestion-pipeline changes get an ingestion +expert plus one language expert per changed language extractor; embeddings +changes an embeddings expert; LadybugDB/storage changes a Ladybug expert. + +Four cross-cutting lenses run regardless of domain: + +- **Architectural fit** — the change lands where the architecture says the + concern lives, reuses existing seams, and adds no parallel structure. +- **Language conformance** — the repo's own type/lint/test contract as + configured (tsconfig strictness, lint rules, test conventions); in a + strict TypeScript repo, for example: strictness intact, no `any`/`as any` + escapes, module boundaries typed. Judge by the repo's contract, never a + universal style bar. +- **Definition of Done** — changed behavior has tests, docs the change makes + stale are updated, and sync/drift guards (shipped copies, manifests, + changelogs) still hold. +- **Simplicity** — YAGNI and clear-code check: flag speculative abstraction, + unused knobs, and overengineering; the smallest diff that meets the + Definition of Done is the standard. + +Scale effort to the surface: a single-domain change of a few files gets one +combined pass covering its domain lens plus the four cross-cutting checks; +a multi-domain change gets one lens per touched area — run as parallel +subagents where the harness supports them, each scoped to its own files +plus the shared graph evidence, and as sequential passes otherwise. Never +spawn a lens for a domain the diff does not touch. Merge lenses that ground +in the same material — two lenses reading the same files pay twice for one +read's coverage, so give one reviewer both charges. Where the harness +offers model or effort tiers, run mechanical lenses (rename sweeps, +doc-consistency checks) on a cheaper tier and reserve the strongest engine +for adversarial judgment. Every lens reports +through the Finding standard below; merge and dedup before the verdict, +dropping anything without a concrete failing scenario. + +## Finding standard + +Report a finding only when the reviewed change introduces a concrete defect, +regression, security issue, compatibility break, material coverage gap, or a +maintainability cost with a concrete carrying scenario (a dead knob, a +duplicated contract, a drift-prone copy). +Each finding must include: + +- severity and a precise `path:line` anchor; +- the failing scenario or contract; +- GitNexus evidence (dependent symbol/process) when applicable; +- why existing code or tests do not mitigate it; +- a concise remediation or missing test. + +Do not report style preferences, pre-existing issues, raw risk counts, or +speculation as defects.

Record its path/version and any available + source/build identity; do not manufacture provenance from timestamps. +4. Read `gitnexus://repo/{name}/context` — codebase overview + staleness check. + **Freshness gate.** Plans built on a stale graph make stale blast-radius + claims — but a re-index is the largest fixed cost a planning session + carries, so the gate is category-priced: + - Compact-plan categories default to `freshness: accept`: plan on the + current graph with source verification weighted higher — their plans + cite little graph evidence. Escalate to a refresh mid-plan only when a + graph claim becomes load-bearing (e.g. Proposed Changes rest on a d=1 + dependent list), and only then. + - Full-plan categories default to `freshness: strict`, and under it: + - **Analyzer provenance check — before any refresh.** Compare the resolved + runner identity with the index metadata and, in an analyzer-source + checkout, with current analyzer source. If identity is stale or unknown, + do not build output and do not make that graph load-bearing. Record a + **stale analyzer provenance — source-weighted limitation** in + `index_refresh`, the plan header, and §12; rely on targeted source reads + or hand execution to `gitnexus-work`, which owns the build-current gate. + - Stale index → run `analyze --index-only` via the resolved runner + (append `--pdg` when the task category will reach Phase 3) and re-read + the context resource **only when runner provenance is known-current**. + Refresh budget, stated once here: at most one `--index-only` refresh in + Phase 1 **plus** at most one later `--pdg` upgrade in Phase 3 (only when + Phase 1's refresh lacked `--pdg`) per planning session — a Deepen run is + its own session. Record each command, runner identity, and outcome in the + ledger's `index_refresh`. + - Refresh failed or impractical (no write access to the index, prohibitive + repo size), or `freshness: accept` was passed → proceed on the stale + graph, weight source verification higher, and state the staleness and + the skipped refresh in the plan header and Assumptions. + - Resources unreadable but tools working → proceed on tools alone, treat + freshness as unknown (weight source higher), and note it in the plan. + - GitNexus unavailable entirely → switch to **Fallback mode** (below). +5. For architecture-scale tasks only, also read + `gitnexus://repo/{name}/clusters` and `.../processes`. + +## Phase 2 — Graph navigation ladder + +Use the narrowest operation that answers the current ledger question, in this +order. Budgets: at most `max_primary_symbols` (5) primary symbols and +`max_related_symbols` (20) related symbols active in the ledger. + +1. `query {search_query, task_context}` — locate concepts, execution flows, + modules, and related tests for the task. +2. `context {name}` — 360° view of each candidate primary symbol: callers, + callees, categorized refs, processes. Promote to primary or discard. An + `ambiguous` result (ranked candidates) is answered by one retry narrowed + with `kind` / `file_path` / uid — that retry is an allowed repeat. +3. `impact {target, direction}` — upstream/downstream blast radius for shared + or high-connectivity symbols (`maxDepth` = `impact_depth`; `summaryOnly: +true` first for hub symbols, then drill in — an allowed repeat). Record the + d=1 items — the **direct (depth-1) dependents** — the plan must account + for every one of them. +4. `trace {from, to}` — when the task hinges on _how A reaches B_, one call + instead of chained context hops. +5. Statement-level PDG — Phase 3, for the functions the change centers on. +6. `cypher` — last resort, only for a precise graph question the tools above + cannot express. Read `gitnexus://repo/{name}/schema` first; anchor and + LIMIT every query. +7. `detect_changes {scope}` — only when planning against existing uncommitted + or branch work. + +Do not run every tool by default. A local test fix may finish the ladder at +step 2. + +## Phase 3 — Statement-level PDG slice + +For the 1–3 functions most central to the change, build a bounded **PDG +context slice**. Read `references/pdg-slice.md` and follow it — it owns the +tool calls, inclusion criteria, depth bounds, slice schema, the security and +performance modes, and the no-PDG-layer fallback. + +## Phase 4 — Targeted source verification + +GitNexus said where to look; now confirm what is there. Using ordinary file +reads (exact line ranges, not whole files unless genuinely required): + +- Read every source range the plan will cite: signatures, branch conditions, + state mutations, error paths, nearby comments that change behavior. Compact + plans cite less — verify what they cite, don't expand the citation set to + have more to verify. +- Read the tests GitNexus associated with the primary symbols; never claim a + test exists without having located it. +- Verify the build/test commands the plan will name actually exist + (package.json scripts / CI workflows), and prefer the script form that + carries its prerequisites (pre-hooks) over invoking underlying binaries + directly. +- Check repo conventions that constrain the change (AGENTS.md, GUARDRAILS.md, + lint/build config) — only the parts the change touches. +- Mark each ledger symbol `source_verified: true` as you go. **A symbol that + is named in Proposed Changes must be source-verified.** +- On graph/source disagreement: trust source, record the discrepancy in the + ledger and the plan, recommend re-indexing. Never present stale graph data + as fact. +- Immediately before composition, recompute the versioned + `evidence_provenance` snapshot by invoking + `scripts/evidence-provenance.mjs` exactly as specified in + `references/evidence-provenance.md`: the + canonical global dirty digest over all dirty paths and the sorted manifest + of every cited path, including object kind and + HEAD/index/worktree/untracked layer digests. Re-read any citation that + changed during planning. Exclude only the generated plan path. + +Evidence hierarchy, strongest first: current source and config → current tests +and executable behavior → compiler/build/lint output → GitNexus graph and PDG +→ documentation and comments. + +## Phase 5 — Compose the plan + +1. Read `references/plan-template.md` and fill the category's form — compact + (core sections, ≤80 lines excluding the pack) or full (all 13 sections) — + from the ledger, tagging claims with the template's four classes — + `[verified]`, `[graph]`, `[inferred]`, `[assumed]` — and routing open + questions to §12. +2. Build the implementation context pack per `references/context-pack.md` + (this is section 11 of the plan), including mandatory + `evidence_provenance` in compact and full forms. +3. Set `generated_plan_path` to + `docs/plans/YYYY-MM-DD-gitnexus-plan-<slug>.md` under the root of the repo + being planned (the Phase 1 target repo, not necessarily the cwd); use a + 3–5-word kebab-case slug and repo-relative paths inside the document. + Compose the complete document without creating that destination, then + pipe its exact UTF-8 bytes to `scripts/evidence-provenance.mjs write-plan` + as specified in `references/evidence-provenance.md`. The helper safely + creates missing parent directories. Initial planning must not pass + `--replace`. A safe-write failure blocks plan publication: report it and + do not write directly, choose an external destination, or weaken the + repo-relative provenance contract. The snapshot and writer commands apply + the same strict generated-plan filename/date validator; do not substitute a + source, `.git`, or arbitrary `docs/plans/` path in either invocation. +4. Present in chat: objective, proposed-changes summary, implementation + sequence, top risks, open questions, and the plan file path. Do not paste + the whole document into chat. + +## Deepen mode + +`/gitnexus-plan deepen <plan-path>` strengthens an existing plan in place +instead of creating a new one: + +1. Resolve the target repository and normalized repo-relative plan candidate, + then load it with `scripts/evidence-provenance.mjs read-plan --repo <root> +--generated-plan <candidate>` exactly as specified in + `references/evidence-provenance.md`. Reject a missing, external, escaping, + symlinked, or differently scoped path. Decode and parse only the receipt's + exact `plan_bytes_base64`; retain its canonical `generated_plan_path` and + `plan_digest` unchanged for the entire Deepen session. +2. Re-run Phase 1 in full — analyzer provenance check and freshness gate (a + Deepen run is its own session, with its own refresh budget). +3. **Re-anchor before re-pinning.** Recompute the plan's global dirty digest + and cited-path manifest as well as comparing its old HEAD pin with current + HEAD. Changed, renamed, deleted, mixed, or newly absent cited paths get + their ranges re-read — or the claim downgraded — _before_ the pin and + provenance snapshot move. Moving only the commit pin silently launders + dirty or stale claims as verified. +4. Escalate to `depth: deep` (impact_depth 3, clusters/processes read) + unless the invocation overrides knobs explicitly. +5. Seed the ledger from the plan's §11 pack, then re-verify: every + `[graph]`/`[inferred]` claim gets a targeted pass toward `[verified]`; + every `[assumed]` claim is resolved or kept with its reason; direct + (d=1) dependent accounting is re-checked against the refreshed graph; + PDG slices are built or expanded for the central functions when the + layer is present. +6. **Reconcile execution state.** If `gitnexus-work` already landed commits + for this plan (a mid-execution route-back), mark the §7 steps present at + HEAD as completed and re-sequence the remainder — the rewritten plan must + be executable from the top without redoing landed steps. +7. Strengthen whatever the deeper pass showed thin — test scenarios, risks, + Definition of Done — and carry claim-tag upgrades through the prose. +8. Rewrite the **same canonical file** through + `scripts/evidence-provenance.mjs write-plan --replace +--expected-plan-path <retained-read-plan-path> +--expected-plan-digest <retained-read-plan-digest>`: same 13 sections, + context pack kept in sync, evidence header updated. `--replace` is reserved + for Deepen mode, and both expected values must come from the same read-plan + receipt; any digest/path mismatch blocks publication. Retain the successful receipt's + `prior_plan_backup_git_path`; it names the verified Git-admin backup of the + displaced plan. Summarize the delta in chat: claims upgraded, claims that + failed re-verification, sections changed, and that backup path. + +## Configuration + +Baseline defaults — the Phase 0 category posture overrides them, and inline +`key:value` tokens before the task text override both (the repo has no +skill-config file mechanism; invocation args are the mechanism): + +| Knob | Default | Meaning | +| --------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| `depth` | by category | `narrow` = `impact_depth` 1, PDG only if one function is clearly central; `default` = this table; `deep` = `impact_depth` 3 + clusters/processes read | +| `form` | by category | `compact` (core sections + mini-pack, ≤80 lines excl. pack — see `references/plan-template.md`) or `full` (all 13 sections) | +| `impact_depth` | 2 | `maxDepth` for `impact` | +| `pdg_data_depth` | 2 | Data-dependence hops in the PDG slice | +| `pdg_control_depth` | 2 | Control-dependence hops in the PDG slice | +| `max_primary_symbols` | 5 | Ledger budget (active symbols; discards don't count) | +| `max_related_symbols` | 20 | Ledger budget (active symbols; discards don't count) | +| `max_snippet_lines` | 30 | Longest source excerpt quoted in the plan | +| `freshness` | by category | `strict` (full-plan categories) = refresh a stale index (and a missing PDG layer) with `analyze --index-only [--pdg]` before relying on the graph; `accept` (compact categories) = plan on the current graph, source-weighted and labelled, refreshing only if a graph claim becomes load-bearing | + +## Fallback mode (GitNexus or PDG unavailable) + +1.

Initial mode +therefore cannot overwrite a destination that appears after the absent check. +The writer then flushes the directory and revalidates the committed path by +opening it with `O_NOFOLLOW`, hashing both the original temporary fd and the +path-bound fd, and performing a second descriptor-anchored path identity check +after hashing. A detected mutation or replacement aborts instead of accepting +mixed-era output. + +`--replace` accepts only a pre-existing regular file and is reserved for +Deepen; without it, accidental overwrite is rejected. It also requires the +exact canonical `generated_plan_path` and `plan_digest` from the same session's +`read-plan` receipt. The expected path must exactly equal the write +destination, so identical bytes from one plan cannot authorize another plan. +Immediately before +preservation, the writer hashes the still-held prior-plan fd and rejects any +digest, inode, or path mismatch, including same-inode edits and changes between +read and write. It then atomically moves the current destination without +replacement to a random `gitnexus-plan-backups/` file under the resolved +Git-admin directory and verifies the moved inode and digest against that held +fd. Only then does it publish the new plan with the same atomic no-replace +primitive. A destination that reappears at either boundary is left untouched. + +Every newly created plan or vault directory is fsynced and then fsynced into +its containing directory. Every cross-directory preservation move fsyncs both +its source and destination directories before success or a recovery path is +reported. After temporary bytes exist, a failed publication or verification preserves +every available prior, displaced, unpublished, or intended plan in that +Git-admin vault before reporting failure. Each reported recovery is reopened +from a freshly resolved Git root and verified before the error names it as +`git-path:gitnexus-plan-backups/<random-name>`. Resolve that value with +`git rev-parse --git-path gitnexus-plan-backups/<random-name>`; never interpret +it as a repo-relative working-tree path. This remains valid if the held plan +parent was renamed after publication. The writer never reports recovery +through a stale lexical parent and never performs an identity-check-then-unlink +rollback that could delete a racer's replacement. Read-only or unsupported +checkouts produce a blocking error. Callers must not bypass the helper, +redirect to an external path, or weaken these checks. + +## Canonical bytes + +The `global_dirty_digest.value` is lowercase SHA-256 (without a `sha256:` +prefix) over this byte stream. All textual values are their exact UTF-8 bytes. +`NUL` below is one `0x00` byte. + +1. Prefix fields, each followed by NUL, then one additional NUL: + `gitnexus-evidence-provenance`, `schema_version`, `2`. +2. Zero or more records sorted by unsigned lexicographic comparison of the + normalized path's UTF-8 bytes. Locale and filesystem order are forbidden. +3. Each record is `record` + NUL, then the following fixed-order sequence of + `field-name` + NUL + `field-value` + NUL pairs, then one additional NUL: + `path`, `state`, `head_kind`, `index_kind`, `worktree_kind`, + `untracked_kind`, `rename_from`, `rename_to`, `head_digest`, + `index_digest`, `worktree_digest`, `untracked_digest`. +4. The literal `absent` represents every unavailable rename endpoint, object + kind, and layer digest in canonical bytes. It is never an empty string. + +The schema's canonicalization literal is exactly +`gitnexus-evidence-provenance-v2 NUL-framed UTF-8 records`. The fixed field +count plus the extra NUL after prefix/record makes framing unambiguous; values +cannot contain NUL. Duplicate normalized paths are rejected. + +## Records, renames, and states + +The raw dirty set comes from Git porcelain v2 with NUL termination, all +untracked files, submodule inspection enabled, a fixed 50% rename threshold, +and both `diff.renameLimit=0` and `status.renameLimit=0`, so repository config +cannot cap rename candidates. Raw porcelain facts that share a path are merged +into one canonical record. A rename contributes two endpoint facts: + +- old endpoint: `path=<old>`, `rename_from=absent`, `rename_to=<new>`; +- new endpoint: `path=<new>`, `rename_from=<old>`, `rename_to=absent`. + +Both normally have state `renamed`; record sorting, not old/new role, +determines order. A worktree-dirty rename destination or any endpoint that also +has another fact is `mixed`, with rename metadata retained. When either endpoint +is cited, the cited manifest expands to include both. + +Ordinary `XY` status maps to `mixed` when index and worktree columns are both +dirty, otherwise `deleted` for a deletion, `staged` for index-only change, and +`unstaged` for worktree-only change. `?` is `untracked`. Multiple distinct +facts for the same path become `mixed`; a staged deletion plus a recreated file +therefore retains HEAD/index facts while the filesystem object is recorded in +the untracked layer. `? child/` is Git's embedded-directory marker: the trailing +slash is removed before path normalization and `child` is materialized as one +bounded directory object. A cited path outside the dirty set is `clean`, +`untracked` when it exists only outside Git layers, or `absent` when no layer +exists. + +## Object and digest rules + +Every present layer digest is `sha256:<lowercase-hex>`: + +- HEAD regular/symlink: SHA-256 of the exact Git blob bytes. HEAD directory: + SHA-256 of the exact raw Git tree bytes. HEAD gitlink: SHA-256 of the ASCII + object ID stored by the tree. +- Index regular/symlink: SHA-256 of the stage-0 Git blob bytes. Index gitlink: + SHA-256 of its ASCII object ID. The index has no directory layer. Any + non-stage-0 entry is rejected. +- Tracked worktree regular: raw file bytes, opened without following symlinks. + Symlink: raw link-target bytes. Gitlink: ASCII object ID at the checked-out + nested HEAD, but only after `rev-parse --show-toplevel` proves that the + directory itself is the nested repository root, `HEAD` resolves there, and + porcelain v2 reports no staged, unstaged, untracked, or ignored nested changes. The + same root, HEAD, and clean-status proof is repeated by the mutation guard. A + dirty, empty, uninitialized, or parent-falling-through gitlink fails closed. + Directory: the v1 directory stream described below. +- A path absent from both HEAD and index places the filesystem object in the + `untracked` layer and marks `worktree` absent. A Git-backed path places it in + `worktree` and marks `untracked` absent. A missing layer uses literal + `absent` for both kind and digest; an empty file is the SHA-256 of zero bytes. + +Filesystem directory bytes use prefix fields +`gitnexus-evidence-directory`, `schema_version`, `1`, the same NUL framing, +and recursive entries sorted by unsigned UTF-8 relative-path bytes. Each entry +has fixed fields `path`, `kind`, `digest`. A single bottom-up filesystem walk +visits each node once and returns each child digest plus the flattened subtree +needed to preserve those canonical bytes; links are never followed. When the +directory is proven to be an exact nested Git top-level, only its administrative +`.git` entry is excluded. Every other child, including working files and nested +directories, remains evidence. + +Each directory object is bounded to 10,000 visited entries, depth 256, and 256 +MiB of regular-file content. Exceeding a bound fails closed. These bounds apply +independently to each top-level directory object materialized by a record. + +HEAD objects are read only from the full object ID captured at snapshot start; +the symbolic `HEAD` name is never re-resolved for layers. Index layers are +parsed from one captured stage-0 listing. The helper guards the corresponding +HEAD/ref/reflog controls and raw index file, compares the captured listing at +the end, and rejects ordinary A-to-B-to-A mutations instead of accepting +mixed-era layers. + +Regular files are read through an `O_NOFOLLOW` descriptor with before/after +identity checks. Symlinks use lstat/readlink/lstat; directories record identity +before and after their inventory. The helper also compares raw porcelain-v2 +status and HEAD at the start and end, then rechecks filesystem guards. An +absent cited path holds a no-follow descriptor for the nearest existing parent +and records the first missing component or leaf; that anchored absence is +checked both before and after the final Git status pass, so a newly created +ignored path cannot evade porcelain. Any observed race rejects the snapshot +rather than emitting mixed-era evidence. diff --git a/gitnexus/skills/gitnexus-plan/references/pdg-slice.md b/gitnexus/skills/gitnexus-plan/references/pdg-slice.md new file mode 100644 index 000000000..d6b3da201 --- /dev/null +++ b/gitnexus/skills/gitnexus-plan/references/pdg-slice.md @@ -0,0 +1,109 @@ +# Building the PDG context slice + +Statement-level evidence for the 1–3 functions most central to the change. +Goal: a compact slice the planning LLM can hold, never a graph dump. + +## Tools (all verified against `gitnexus/src/mcp/tools.ts`) + +| Question | Call | +| --- | --- | +| Under what condition does X run?

Fetch those exact commits without +switching the user's branch.

Untracked files are not guaranteed to appear in Git diff or graph +mapping, so read them directly and list them in the review provenance. + +## Align the checkout and index + +The graph and diff must describe the same head. Reuse an existing worktree only +when it is at the exact target SHA. Otherwise create a temporary detached +worktree for the PR/ref head, review there, and remove only that temporary +worktree afterward. Never switch or reset the user's current worktree. + +Check GitNexus status in the target worktree. If stale, run +`node .gitnexus/run.cjs analyze --index-only` before trusting graph results +(temporary worktrees never carry the gitignored `run.cjs` — fall back to the +installed `gitnexus` CLI, then `npx gitnexus`), and include `--pdg` in that +same refresh when the diff plausibly touches trust or data-flow boundaries, +so the taint pass below doesn't pay a second full analyze. Taint and +dependence evidence needs that PDG layer: when the workflow's taint pass +finds it missing, rebuild with `analyze --pdg --index-only` and record the +rebuild in provenance. For local changes, refresh the index so new or +modified source is represented. +If an exact target checkout/index cannot be established, state the limitation +and do not claim a complete graph-backed review. + +## Review workflow + +1. Read the full diff and changed-file list. Separate generated files, + dependency churn, tests, and behavior changes. +2. Run `detect_changes` against the exact surface: + - PR/branch/`...`: `scope: "compare"`, `base_ref: <merge-base SHA>`. + - Explicit `A..B`: `scope: "compare"`, `base_ref: <A SHA>` from a worktree + at `B`. + - Local: `scope: "staged"`, `"unstaged"`, or `"all"`. + Pass `worktree` when the MCP server is attached elsewhere. +3. Run upstream `impact` with `includeTests: true` for each behaviorally changed + symbol. Prioritize public contracts, shared types, control flow, persistence, + security boundaries, and error handling; skip mechanical/generated changes. +4. Inspect every direct (`d=1`) dependent that is outside the diff. A dependent + outside the diff is a lead, not automatically a bug—verify the changed + contract and caller behavior in source. +5. Use `context` on key or ambiguous symbols and inspect affected execution + flows. Read the surrounding implementation and tests at cited locations. +6. **Taint and dependence pass.** For changed code on trust or data-flow + boundaries — external input, persistence, process execution, network, + auth — run `explain` on the changed files or symbols and judge its + source→sink taint findings against the diff: a flow the change + introduces, or a sanitizer/guard the change removes, is a finding; a + pre-existing flow is context, not a defect of this change. When the + change claims to guard or sanitize something, verify with `pdg_query`: + what controls the changed statement, and where its values flow. This + needs a `--pdg` index; if one cannot be built, state that the taint pass + was skipped rather than implying coverage. +7. Check whether tests exercise the changed behavior, boundary conditions, and + affected flows. Run focused read-only validation when practical. When the + diff refreshes a committed baseline, fingerprint, or golden, re-run the + exact CI check command against the head instead of trusting the committed + value — a stale artifact is invisible in the diff and fails only in CI. +8. Reconcile graph evidence with the raw diff. New files, dynamic dispatch, + configuration, reflection, and untracked content may require direct review + even when graph results are empty. Version and invalidation constants are + review surface: when the diff changes what gets emitted or persisted, + verify every schema/version constant gating caches, incremental + writebacks, and fingerprint baselines was bumped or regenerated — in + GitNexus itself, for example: `INCREMENTAL_SCHEMA_VERSION` (the + incremental write set covers only changed files, so new cross-file edges + never reach an existing index without the bump), the parse-store + `SCHEMA_BUMP`, and both bench fingerprint sets. + +## Expert lenses + +Depth comes from matching reviewers to what actually changed, not from one +generalist pass. After workflow step 2, group the changed files and symbols +by the functional areas the graph already knows — the index's cluster +listing; `context` names each symbol's cluster — and give each touched area +an expert lens: a reviewer charged with that domain's contracts, invariants, +and failure modes, grounded in the repo's own material (architecture docs, +agent rules, the domain's tests) before judging the diff. A lens verifies, +not just reads: when the changed code is a pure function reachable from the +repo's own toolchain — parsers, extractors, capture emitters, formatters — +execute it on the candidate failing shape (a scratch probe, deleted +afterward) and cite the observed output. An empirical probe outranks source +reading in the evidence hierarchy; role swaps, dead branches, and +error-recovery-dependent behavior repeatedly pass a reading and fail a +ten-line probe. The numbered +workflow runs exactly once; dispatch the lens passes after step 6, handing +each lens the evidence already collected rather than letting lenses repeat +the `impact`, `context`, or taint calls. In GitNexus +itself, for example: shared ingestion-pipeline changes get an ingestion +expert plus one language expert per changed language extractor; embeddings +changes an embeddings expert; LadybugDB/storage changes a Ladybug expert. + +Four cross-cutting lenses run regardless of domain: + +- **Architectural fit** — the change lands where the architecture says the + concern lives, reuses existing seams, and adds no parallel structure. +- **Language conformance** — the repo's own type/lint/test contract as + configured (tsconfig strictness, lint rules, test conventions); in a + strict TypeScript repo, for example: strictness intact, no `any`/`as any` + escapes, module boundaries typed. Judge by the repo's contract, never a + universal style bar. +- **Definition of Done** — changed behavior has tests, docs the change makes + stale are updated, and sync/drift guards (shipped copies, manifests, + changelogs) still hold. +- **Simplicity** — YAGNI and clear-code check: flag speculative abstraction, + unused knobs, and overengineering; the smallest diff that meets the + Definition of Done is the standard. + +Scale effort to the surface: a single-domain change of a few files gets one +combined pass covering its domain lens plus the four cross-cutting checks; +a multi-domain change gets one lens per touched area — run as parallel +subagents where the harness supports them, each scoped to its own files +plus the shared graph evidence, and as sequential passes otherwise. Never +spawn a lens for a domain the diff does not touch. Merge lenses that ground +in the same material — two lenses reading the same files pay twice for one +read's coverage, so give one reviewer both charges. Where the harness +offers model or effort tiers, run mechanical lenses (rename sweeps, +doc-consistency checks) on a cheaper tier and reserve the strongest engine +for adversarial judgment. Every lens reports +through the Finding standard below; merge and dedup before the verdict, +dropping anything without a concrete failing scenario. + +## Finding standard + +Report a finding only when the reviewed change introduces a concrete defect, +regression, security issue, compatibility break, material coverage gap, or a +maintainability cost with a concrete carrying scenario (a dead knob, a +duplicated contract, a drift-prone copy). +Each finding must include: + +- severity and a precise `path:line` anchor; +- the failing scenario or contract; +- GitNexus evidence (dependent symbol/process) when applicable; +- why existing code or tests do not mitigate it; +- a concise remediation or missing test. + +Do not report style preferences, pre-existing issues, raw risk counts, or +speculation as defects.

Never edit the plan body. +2. Parse the §11 `implementation_context` pack: `acceptance_criteria`, + `evidence_provenance`, `primary_symbols`, `related_symbols`, + `files_to_modify`, `execution_path`, `pdg_constraints`, + `architectural_patterns`, `tests`, `verification_commands`, `risks`, + `assumptions`, `open_questions`, `avoid`.

Before relying on it, require exact byte-for-byte + equality between the read-plan receipt's canonical `generated_plan_path` + and `evidence_provenance.generated_plan_path`. +3. **Two-layer drift check — always recompute.** Even when current HEAD is the + same HEAD as the plan pin, recompute both the canonical global dirty digest + and the sorted cited-path manifest. Read + `references/evidence-provenance.md`, then invoke this skill's + `scripts/evidence-provenance.mjs` with the plan's exact + `generated_plan_path`, every cited manifest path, and schema version 2. + Never recreate its bytes in shell or prose.

Honor the generated-plan exclusion exactly; do not + exclude all plans. +4. **Re-anchor on either mismatch.** Missing or legacy provenance, a HEAD + mismatch, or a global dirty digest mismatch requires a conservative + re-anchor before work: + - Diff every cited-path manifest entry. Changed cited paths — including + staged-only, unstaged-only, deleted, both rename endpoints, mixed + staged+unstaged, and disappeared untracked paths — get their cited ranges + re-read before reliance. + - Compare the current whole-tree dirty set with the pinned global digest. + New uncited dirty paths get a scope assessment: determine whether they + overlap the plan, requirements, tests, or a key technical decision; do not + silently ignore them merely because they are uncited. + - Unreadable or unclassifiable cited evidence blocks every dependent step + until it can be restored, read, or resolved with the user. Never substitute + an invented digest or treat absence as an empty file. + - Keep the re-anchor result in session state; never mutate the plan body. + Use Deepen only if reconciliation invalidates scope, requirements, a key + technical decision (KTD), or the planned implementation seam. Ordinary + byte drift that leaves those decisions valid is re-verified locally. +5. **Re-verify `assumptions` cheaply** (each one names what to check). + A failed assumption is a stop-and-replan signal for the steps that + depend on it, not something to code around silently. +6. Note `open_questions` — if one blocks a step and the answer materially + changes the work, ask the user before that step, not after. +7. **Pre-completed check.** If commits for this plan already exist on the + branch (a prior partial run, or a post-route-back Deepen cycle), verify + which §7 steps have landed at HEAD: those are skipped and reported as + pre-completed, and execution resumes at the first unlanded step. All + steps landed → report that and stop. + +## Phase 2 — Environment + +- On the default branch → create a feature branch named from the plan slug. + On a feature branch already → stay only if it is meaningful _for this + plan_ (name matches the plan slug, or the user confirms); otherwise + branch from here with the slug name. +- If the plan document is not yet committed, commit it now + (`docs(plans): add <slug> plan`) — the plan travels with the work it + drives, and the final review diff then includes it. +- Confirm the `verification_commands` from the pack actually run in this + checkout (dependencies installed, builds present) before starting, not + after the last step. + +### Build-current/index-current procedure + +This is the single graph-freshness procedure owned by `gitnexus-work`; it +applies in plan mode and direct mode. Before every graph-dependent `impact` +query, run the Build-current/index-current procedure. Before final graph +verification, run the same Build-current/index-current procedure again. + +1. Capture current HEAD and working-tree provenance. Read + `gitnexus://repo/<name>/context` and use its typed `index.commit` and + `index.runner_identity` receipt — never infer analyzer identity from prose, + timestamps, or a path alone. Compare `index.commit` with current HEAD. A + current receipt has `schemaVersion: 4`, resolved runtime path/version, CLI + version, invoked-artifact path/digest, build + kind/root/canonicalization/digest, and dependency-runtime + manifest/lockfile/canonicalization/package-count/artifact-count/digest. Its + dependency canonicalization is + `gitnexus-analyzer-dependency-runtime-v4`. The dependency-runtime digest + covers resolved package metadata and complete loadable package payloads, + including JavaScript, JSON, native, Wasm, and parser artifacts; schema-1, + schema-2, and schema-3 receipts are legacy/stale (the MCP context labels + them `runner_identity_schema_status: legacy-or-unknown`). Require MCP + `index.incomplete_reasons: []`. Run the exact candidate CLI's + `status --json` command and require `index.runnerIdentityStatus: current`, + `index.incompleteReasons: []`, and top-level `status: up-to-date`. The + status comparator checks every semantic field while deliberately excluding + only diagnostic `invokedArtifact`; a worker-authored persisted receipt and + the CLI's live receipt may therefore differ in that field without becoming + stale. Missing, malformed, differently versioned, semantically unequal, or + incomplete receipts are unknown/stale, not a match. +2. Relationship-affecting committed and uncommitted edits invalidate + freshness after the last successful procedure run. This includes staged, + unstaged, untracked, deleted, or renamed analyzer/source/config changes + that can alter symbols or edges. Any such edit between steps requires an + inter-step refresh before the next graph query, even when HEAD did not move. +3. If the typed runner receipt is stale or unknown in an analyzer-source + checkout, build current local source using the verified package script. In + this repo: `cd gitnexus && npm run build`. Resolve the package's `bin` + target and run that exact artifact's `status --json` command to capture its + current receipt. Source/build timestamps are a conservative rebuild + trigger, not proof that an artifact is current. +4. Invoke that exact freshly built local CLI from the target repo root with + PDG layers enabled. In this repo: + `node gitnexus/dist/cli/index.js analyze --index-only --pdg`. + Add `--force` when the persisted receipt was absent, malformed, + differently versioned, or unequal so an already-up-to-date fast path cannot + leave legacy/stale provenance in place. The usual project-runner form, + `node .gitnexus/run.cjs analyze`, is acceptable only when its proven runner + identity resolves to that same freshly built artifact. Do not fall back to + an older project runner, global install, or package download after + resolving/building the local artifact. +5. Re-read index context, rerun the exact invoked CLI's `status --json`, and + prove the post-refresh `index.commit` equals current HEAD, MCP + `index.incomplete_reasons` is empty, and its complete + `index.runner_identity` equals status `index.runnerIdentity` (the persisted + receipt). Require status `index.runnerIdentityStatus: current`, empty + `index.incompleteReasons`, and top-level `status: up-to-date`; do not require + raw equality with `current.runnerIdentity` because `invokedArtifact` is a + diagnostic entrypoint deliberately excluded from semantic freshness. + Record the dirty-state digest indexed in this procedure so same-HEAD + uncommitted edits can invalidate it later. +6. Any build, refresh, metadata-read, or identity-verification failure blocks + graph-dependent impact work and final completion. Report the failing + command and evidence; do not continue on an older graph. + +## Phase 3 — Execute the Implementation Sequence + +Work through plan §7 step by step, in order. For each step: + +1. **Fresh impact before editing.** Run the Build-current/index-current + procedure immediately before every graph-dependent + `impact {target, direction: "upstream"}` query. Then account for every + direct (d=1) dependent. HIGH or CRITICAL risk → surface it to the user + with the blast radius before proceeding (repo mandate — see AGENTS.md + GitNexus rules). +2. **Honor the constraints.** `pdg_constraints` entries state ordering and + dependence facts the change must preserve; `avoid` entries are hard + prohibitions; `architectural_patterns` name the shape to mirror (read the + example location before inventing one). +3. **Implement minimally.** The smallest change that completes the step, + following the surrounding code's conventions. +4. **Test from the plan's scenarios.** Each `tests[]` scenario (input → + action → expected outcome) becomes a real test in the named file. Add + coverage the plan missed if the step's behavior demands it; never delete + or weaken an assertion to make a step pass. Prove a new regression test + discriminates: when the failure mode is subtle, run it once against the + pre-fix tree (write the test before the fix, or stash the fix) and watch + it fail — a test that passes both ways pins nothing. +5. **Verify.** Run the step-relevant `verification_commands` (they carry + their build prerequisites; use them as written). If any part of the + change executes from build output — worker entrypoints, dist-shipped + CLIs, bundled assets — rebuild that output before every verification + run: a pass or fail against outdated build output is noise, and "the + fix doesn't work" is more often "the fix never loaded". +6. **Commit atomically.** `detect_changes {scope: "staged"}` before every + commit to confirm only the expected symbols and flows are affected + (repo mandate); then one conventional commit per step. Run stage → + `detect_changes` → commit as one unbroken sequence from the repository + root — interleaving other work between the gate and the commit is how + the gate gets skipped. Unexpected + affected flows → investigate before committing, not after. + +A relationship-affecting implementation edit or commit invalidates the +procedure's prior proof. The next step must perform the required inter-step +refresh before its impact query; final verification refreshes again after the +last edit. + +Steps are independently actionable: after any commit the tree is coherent. +If a step reveals the plan is wrong, stop that step, re-verify the affected +claims at HEAD, and either adapt (small, in-scope deviation — record it in +the commit message and final summary) or route back to `gitnexus-plan` +Deepen mode (structural miss) — with a one-line ask to the user when the +choice isn't obvious. + +## Phase 4 — Finish + +1. Run the full `verification_commands` suite once, at the end, even if + every step already passed individually. +2. Walk plan §13 (Definition of Done) and the pack's `acceptance_criteria` + item by item; anything unmet is either finished now or reported as + explicitly unmet — never silently dropped. +3. **Verify the final knowledge graph.** Before final graph verification, run + the same Build-current/index-current procedure after the last edit, even + when no commit landed or HEAD still equals the original pin. Then run + `detect_changes {scope: "all"}` (or the repo's equivalent final graph + check) against that proven-current index and account for every unexpected + symbol or flow. A procedure failure blocks completion. +4. Report: steps completed, commits made, deviations from the plan (with + why), assumptions that failed re-verification, DoD status, final indexed + commit and runner identity, and anything deferred. Test failures are + reported with their output, not smoothed over. + +## Never + +- Skip the Phase 3 gates: no symbol edit without `impact`, no commit without + `detect_changes`. +- Expand scope beyond the plan — §12's deferred follow-ups stay deferred. +- Mutate the plan body (committing the file verbatim in Phase 2 is not + mutation), weaken failing tests, or present unverified work as verified. + +## Skill feedback (GitNexus repo only) + +If this run exposed friction in this skill's own instructions — wrong or +missing guidance, a wasted tool budget, a phase that misrouted — and the repo +carries `eval/workflow_bench/`, append one JSON line to +`eval/workflow_bench/learnings.jsonl` (create the file if absent): +`{"skill": "gitnexus-work", "date": "YYYY-MM-DD", "task": "<one line>", "friction": "<one line>", "suggestion": "<one line>"}`. +Never edit this skill file itself from a live task: improvements go through +the offline candidate loop (`eval/workflow_bench/README.md` § Prompt and +skill evolution loop), where a candidate must beat the incumbent on the +paired benchmark before a human merges it. diff --git a/gitnexus/skills/gitnexus-work/references/evidence-provenance.md b/gitnexus/skills/gitnexus-work/references/evidence-provenance.md new file mode 100644 index 000000000..c686599da --- /dev/null +++ b/gitnexus/skills/gitnexus-work/references/evidence-provenance.md @@ -0,0 +1,272 @@ +# Evidence provenance serializer v2 and safe plan writer + +This file is the normative byte contract for `evidence_provenance` schema 2. +The adjacent `scripts/evidence-provenance.mjs` is its executable definition. +`gitnexus-plan` and `gitnexus-work` carry byte-identical copies so either skill +can produce the same snapshot without relying on the other skill's install. +It is also the only supported write boundary for a generated plan.

Immediately before publication it revalidates +the parent and the temporary path, inode, size, and digest. Publication uses an +atomic no-replace move relative to the held directory descriptor. Initial mode +therefore cannot overwrite a destination that appears after the absent check. +The writer then flushes the directory and revalidates the committed path by +opening it with `O_NOFOLLOW`, hashing both the original temporary fd and the +path-bound fd, and performing a second descriptor-anchored path identity check +after hashing. A detected mutation or replacement aborts instead of accepting +mixed-era output. + +`--replace` accepts only a pre-existing regular file and is reserved for +Deepen; without it, accidental overwrite is rejected. It also requires the +exact canonical `generated_plan_path` and `plan_digest` from the same session's +`read-plan` receipt. The expected path must exactly equal the write +destination, so identical bytes from one plan cannot authorize another plan. +Immediately before +preservation, the writer hashes the still-held prior-plan fd and rejects any +digest, inode, or path mismatch, including same-inode edits and changes between +read and write. It then atomically moves the current destination without +replacement to a random `gitnexus-plan-backups/` file under the resolved +Git-admin directory and verifies the moved inode and digest against that held +fd. Only then does it publish the new plan with the same atomic no-replace +primitive. A destination that reappears at either boundary is left untouched. + +Every newly created plan or vault directory is fsynced and then fsynced into +its containing directory. Every cross-directory preservation move fsyncs both +its source and destination directories before success or a recovery path is +reported. After temporary bytes exist, a failed publication or verification preserves +every available prior, displaced, unpublished, or intended plan in that +Git-admin vault before reporting failure. Each reported recovery is reopened +from a freshly resolved Git root and verified before the error names it as +`git-path:gitnexus-plan-backups/<random-name>`. Resolve that value with +`git rev-parse --git-path gitnexus-plan-backups/<random-name>`; never interpret +it as a repo-relative working-tree path. This remains valid if the held plan +parent was renamed after publication. The writer never reports recovery +through a stale lexical parent and never performs an identity-check-then-unlink +rollback that could delete a racer's replacement. Read-only or unsupported +checkouts produce a blocking error. Callers must not bypass the helper, +redirect to an external path, or weaken these checks. + +## Canonical bytes + +The `global_dirty_digest.value` is lowercase SHA-256 (without a `sha256:` +prefix) over this byte stream. All textual values are their exact UTF-8 bytes. +`NUL` below is one `0x00` byte. + +1. Prefix fields, each followed by NUL, then one additional NUL: + `gitnexus-evidence-provenance`, `schema_version`, `2`. +2. Zero or more records sorted by unsigned lexicographic comparison of the + normalized path's UTF-8 bytes. Locale and filesystem order are forbidden. +3. Each record is `record` + NUL, then the following fixed-order sequence of + `field-name` + NUL + `field-value` + NUL pairs, then one additional NUL: + `path`, `state`, `head_kind`, `index_kind`, `worktree_kind`, + `untracked_kind`, `rename_from`, `rename_to`, `head_digest`, + `index_digest`, `worktree_digest`, `untracked_digest`. +4. The literal `absent` represents every unavailable rename endpoint, object + kind, and layer digest in canonical bytes. It is never an empty string. + +The schema's canonicalization literal is exactly +`gitnexus-evidence-provenance-v2 NUL-framed UTF-8 records`. The fixed field +count plus the extra NUL after prefix/record makes framing unambiguous; values +cannot contain NUL. Duplicate normalized paths are rejected. + +## Records, renames, and states + +The raw dirty set comes from Git porcelain v2 with NUL termination, all +untracked files, submodule inspection enabled, a fixed 50% rename threshold, +and both `diff.renameLimit=0` and `status.renameLimit=0`, so repository config +cannot cap rename candidates. Raw porcelain facts that share a path are merged +into one canonical record. A rename contributes two endpoint facts: + +- old endpoint: `path=<old>`, `rename_from=absent`, `rename_to=<new>`; +- new endpoint: `path=<new>`, `rename_from=<old>`, `rename_to=absent`. + +Both normally have state `renamed`; record sorting, not old/new role, +determines order. A worktree-dirty rename destination or any endpoint that also +has another fact is `mixed`, with rename metadata retained. When either endpoint +is cited, the cited manifest expands to include both. + +Ordinary `XY` status maps to `mixed` when index and worktree columns are both +dirty, otherwise `deleted` for a deletion, `staged` for index-only change, and +`unstaged` for worktree-only change. `?` is `untracked`. Multiple distinct +facts for the same path become `mixed`; a staged deletion plus a recreated file +therefore retains HEAD/index facts while the filesystem object is recorded in +the untracked layer. `? child/` is Git's embedded-directory marker: the trailing +slash is removed before path normalization and `child` is materialized as one +bounded directory object. A cited path outside the dirty set is `clean`, +`untracked` when it exists only outside Git layers, or `absent` when no layer +exists. + +## Object and digest rules + +Every present layer digest is `sha256:<lowercase-hex>`: + +- HEAD regular/symlink: SHA-256 of the exact Git blob bytes. HEAD directory: + SHA-256 of the exact raw Git tree bytes. HEAD gitlink: SHA-256 of the ASCII + object ID stored by the tree. +- Index regular/symlink: SHA-256 of the stage-0 Git blob bytes. Index gitlink: + SHA-256 of its ASCII object ID. The index has no directory layer. Any + non-stage-0 entry is rejected. +- Tracked worktree regular: raw file bytes, opened without following symlinks. + Symlink: raw link-target bytes. Gitlink: ASCII object ID at the checked-out + nested HEAD, but only after `rev-parse --show-toplevel` proves that the + directory itself is the nested repository root, `HEAD` resolves there, and + porcelain v2 reports no staged, unstaged, untracked, or ignored nested changes. The + same root, HEAD, and clean-status proof is repeated by the mutation guard. A + dirty, empty, uninitialized, or parent-falling-through gitlink fails closed. + Directory: the v1 directory stream described below. +- A path absent from both HEAD and index places the filesystem object in the + `untracked` layer and marks `worktree` absent. A Git-backed path places it in + `worktree` and marks `untracked` absent. A missing layer uses literal + `absent` for both kind and digest; an empty file is the SHA-256 of zero bytes. + +Filesystem directory bytes use prefix fields +`gitnexus-evidence-directory`, `schema_version`, `1`, the same NUL framing, +and recursive entries sorted by unsigned UTF-8 relative-path bytes. Each entry +has fixed fields `path`, `kind`, `digest`. A single bottom-up filesystem walk +visits each node once and returns each child digest plus the flattened subtree +needed to preserve those canonical bytes; links are never followed. When the +directory is proven to be an exact nested Git top-level, only its administrative +`.git` entry is excluded. Every other child, including working files and nested +directories, remains evidence. + +Each directory object is bounded to 10,000 visited entries, depth 256, and 256 +MiB of regular-file content. Exceeding a bound fails closed. These bounds apply +independently to each top-level directory object materialized by a record. + +HEAD objects are read only from the full object ID captured at snapshot start; +the symbolic `HEAD` name is never re-resolved for layers. Index layers are +parsed from one captured stage-0 listing. The helper guards the corresponding +HEAD/ref/reflog controls and raw index file, compares the captured listing at +the end, and rejects ordinary A-to-B-to-A mutations instead of accepting +mixed-era layers. + +Regular files are read through an `O_NOFOLLOW` descriptor with before/after +identity checks. Symlinks use lstat/readlink/lstat; directories record identity +before and after their inventory. The helper also compares raw porcelain-v2 +status and HEAD at the start and end, then rechecks filesystem guards. An +absent cited path holds a no-follow descriptor for the nearest existing parent +and records the first missing component or leaf; that anchored absence is +checked both before and after the final Git status pass, so a newly created +ignored path cannot evade porcelain. Any observed race rejects the snapshot +rather than emitting mixed-era evidence. diff --git a/gitnexus/skills/gitnexus-work/scripts/evidence-provenance.mjs b/gitnexus/skills/gitnexus-work/scripts/evidence-provenance.mjs new file mode 100644 index 000000000..181d2120b --- /dev/null +++ b/gitnexus/skills/gitnexus-work/scripts/evidence-provenance.mjs @@ -0,0 +1,2084 @@ +#!/usr/bin/env node + +import { createHash, randomBytes } from 'node:crypto'; +import fs from 'node:fs'; +import path from 'node:path'; +import process from 'node:process'; +import { spawnSync } from 'node:child_process'; +import { fileURLToPath } from 'node:url'; + +export const EVIDENCE_PROVENANCE_SCHEMA_VERSION = 2; +export const EVIDENCE_PROVENANCE_CANONICALIZATION = + 'gitnexus-evidence-provenance-v2 NUL-framed UTF-8 records'; + +const ABSENT = 'absent'; +const OBJECT_KINDS = new Set(['regular', 'symlink', 'gitlink', 'directory', ABSENT]); +const STATES = new Set([ + 'clean', + 'staged', + 'unstaged', + 'untracked', + 'deleted', + 'renamed', + 'mixed', + ABSENT, +]); +const RECORD_FIELDS = [ + 'path', + 'state', + 'head_kind', + 'index_kind', + 'worktree_kind', + 'untracked_kind', + 'rename_from', + 'rename_to', + 'head_digest', + 'index_digest', + 'worktree_digest', + 'untracked_digest', +]; +const UTF8_FATAL = new TextDecoder('utf-8', { fatal: true }); +const MAX_GIT_OUTPUT = 1024 * 1024 * 1024; +const MAX_PLAN_BYTES = 16 * 1024 * 1024; +const GENERATED_PLAN_READ_PATTERN = /^docs\/plans\/[^/]*gitnexus-plan[^/]*\.md$/; +const GENERATED_PLAN_WRITE_PATTERN = + /^docs\/plans\/(\d{4}-\d{2}-\d{2})-gitnexus-plan-[a-z0-9]+(?:-[a-z0-9]+){2,4}\.md$/; +export const DIRECTORY_LIMITS = Object.freeze({ + maxEntries: 10_000, + maxDepth: 256, + maxBytes: 256 * 1024 * 1024, +}); + +function sha256(bytes) { + return `sha256:${createHash('sha256').update(bytes).digest('hex')}`; +} + +function statIdentity(stat) { + return [stat.dev, stat.ino, stat.mode, stat.nlink, stat.size, stat.mtimeNs, stat.ctimeNs] + .map(String) + .join(':'); +} + +function assertStableIdentity(before, after, label) { + if (statIdentity(before) !== statIdentity(after)) { + throw new Error(`${label} changed while evidence was being read`); + } +} + +function hashFile(file, mutationGuards, directoryTraversal) { + const hash = createHash('sha256'); + const noFollow = fs.constants.O_NOFOLLOW ?? 0; + const fd = fs.openSync(file, fs.constants.O_RDONLY | noFollow); + const buffer = Buffer.allocUnsafe(1024 * 1024); + try { + const before = fs.fstatSync(fd, { bigint: true }); + if (!before.isFile()) throw new Error(`Expected a regular file at ${file}`); + if (directoryTraversal) { + directoryTraversal.bytes += before.size; + if (directoryTraversal.bytes > BigInt(DIRECTORY_LIMITS.maxBytes)) { + throw new Error(`Directory inventory exceeds ${DIRECTORY_LIMITS.maxBytes} content bytes`); + } + } + for (;;) { + const count = fs.readSync(fd, buffer, 0, buffer.length, null); + if (count === 0) break; + hash.update(buffer.subarray(0, count)); + } + const after = fs.fstatSync(fd, { bigint: true }); + assertStableIdentity(before, after, file); + mutationGuards.push({ type: 'stat', absolute: file, identity: statIdentity(after) }); + } finally { + fs.closeSync(fd); + } + return `sha256:${hash.digest('hex')}`; +} + +function git(repo, args, { allowFailure = false, input } = {}) { + const result = spawnSync('git', ['-C', repo, ...args], { + encoding: null, + env: { ...process.env, LANG: 'C', LC_ALL: 'C', GIT_OPTIONAL_LOCKS: '0' }, + input, + maxBuffer: MAX_GIT_OUTPUT, + windowsHide: true, + }); + if (result.error) throw result.error; + if (result.status !== 0 && !allowFailure) { + const stderr = Buffer.from(result.stderr ??

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * fix(ci): provision ~/GitNexus so the benchmark repo resolves on CI Every scenario in tasks.scenarios.yaml addresses the target repo as ~/GitNexus; runner_tasks.py resolves it with expanduser().resolve() then `git -C <repo> rev-parse`, which raises when the path is missing. On a hosted runner the checkout lands in $GITHUB_WORKSPACE and nothing created ~/GitNexus, so the first real run failed at task-binding. Symlink ~/GitNexus -> $GITHUB_WORKSPACE before the loop. The checkout uses fetch-depth: 0 (full history for the parentless clone), and the benchmark only clones the repo copy-on-write and mounts deps read-only, so the checkout is never mutated. GITNEXUS_BENCH_ORACLE_ROOT stays unset — it defaults to the in-repo oracles dir and is staged by the harness. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * fix(ci): harden promotion summary output and PR branch recovery Three fixes to the promotion-detection and PR-open steps: - GITHUB_OUTPUT summary used a fixed `PROMOTION_EOF` heredoc delimiter; a value containing that marker on its own line could close the block early and inject output keys. Use a per-run random delimiter, matching the pattern already in tree-sitter-upgrade-readiness.yml. - The summary concatenated every generation's promotion.json (including rejected ones), so the PR body could show a losing generation's decisions. The loop returns on the first promotion, so emit only the highest-numbered gen-N/bench/promotion.json — the decision that fired. - The promotion branch name omitted the run attempt. GITHUB_RUN_ID is stable across re-runs, so a re-run after push-succeeds/PR-create-fails could never push. Include ${GITHUB_RUN_ATTEMPT} (the artifact name already does). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * fix(ci): least-privilege the promotion App token and gate on an Environment The Mint-App-Token step passed only app-id + private-key, so the minted token inherited every permission the Release App installation holds (including Workflows: write) — far more than "push a branch, open a PR". Switch to `client-id` (as publish.yml does) and request only permission-contents: write + permission-pull-requests: write. Bind the job to a protected Environment (gitnexus-evolution) so promotion runs can be gated server-side. workflow_dispatch runs the workflow and in-tree evolve.py from the *dispatched ref*, so a code-side ref guard is removable by the dispatched branch itself; an Environment deployment-branch rule (main only) is the boundary that holds. The admin steps to create it and scope the secrets are documented in the activation checklist.

Correct the comment; the pin is unchanged. - Add `set -euo pipefail` to the two build steps that lacked it, matching every other run block in the file (GitHub's default shell already sets -eo pipefail; this adds -u and consistency).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * fix(eval): redact API tokens from diagnostic fields before artifact upload results.jsonl (runner.py) and proposer-session.json (evolve.py) serialize session records whose error_detail can carry a stderr_tail that echoed the API key. Transcripts are redacted before persistence, but these two sinks were not, and both land in the 14-day evolution artifact. Run each record's serialized JSON through the existing redact_text with the run's auth token before writing. Scoped to these diagnostic sinks only: the promoted overlay and proposal.md are left untouched (the overlay is the applied artifact and must stay byte-identical for apply and the shipped-skills-sync guard). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * test(ci): add a contract test for the skill-evolution workflow No test exercised this workflow's path, which is why both P1 blockers (missing --apply, unresolvable ~/GitNexus task repo) reached production. Parse the workflow YAML and assert the structural contract: --apply is passed, the task repo is provisioned, the promotion branch carries the run attempt, the App token is permission-scoped and the job is Environment- gated, the output summary uses a random delimiter and a single generation, the artifact pin is labelled correctly, and every multi-line shell step sets strict mode. Follows the review-agent-workflow.test.ts precedent. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * feat(ci): run the proposer on its own (stronger) model One `model` input drove both the benchmark arms and the proposer/diagnosis session. Split them: `model` stays the benchmark arms (match the model your skill users run, so a promotion is valid for them and the tasks aren't ceiling-saturated), and a new `proposer_model` input runs the proposer — the harder meta-reasoning task that writes the candidate skill, and only one session per generation, so a stronger model is cheap here. evolve.py already supports --proposer-model; the workflow just didn't expose it. Defaults: arms = claude-sonnet-5, proposer = claude-opus-4-8 (both overridable via workflow_dispatch). The weekly cadence bounds the added spend. Contract test asserts the split stays wired.

Restructure the published review body: verdict-first summary, findings ordered by severity, fixed section order, and every file or symbol reference as a GitHub permalink pinned to the analyzed head SHA (or the merge-base SHA for deleted and rename-old paths) instead of bare path:line text, so references are clickable and render inline previews. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * feat(ci): review agent runs as a coordinated reviewer swarm Implement the review skill's expert-lens section in CI: the main agent spawns four trusted lanes in parallel via the Task tool — correctness, security, blast-radius, and coverage — each a purpose-built persona restricted to Read/Glob/Grep plus the read-only graph MCP tools. Personas live in the canonical skill tree (mirrored to all shipped copies) and are installed into the reviewer's user-scope agents dir from the exact control SHA, so a hostile PR head can never define a lane. Lane reports are treated as unverified claims: the main agent re-anchors findings before publishing, and the publisher's context-evidence gate still requires the main conversation's own successful context call. Bash and the newer Agent tool remain disallowed for every context; the analyze timeout gets swarm headroom (45 -> 60 minutes). The workflow contract test now pins the swarm posture. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * fix(ci): sidechain tool calls can no longer satisfy the evidence gate The review agent's own review of this PR found that proveGraphReview() walked the flat transcript without reading parent_tool_use_id, so a spawned lane's context call could satisfy the publisher's graph-evidence gate the prompt reserves for the orchestrator. Entries with a non-null parent_tool_use_id are still strictly validated (malformed linkage fails the transcript) but are excluded from both candidate context calls and qualifying results; a new fixture proves sidechain-only evidence is rejected while mainline evidence beside sidechain turns still passes. Also gives the orchestrator turn headroom for the four dispatched lanes (--max-turns 100 -> 150), addressing the review's LOW finding. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * refactor(skills): swarm-lane dispatch belongs to the review skill Move the lane orchestration out of the workflow prompt and into the gitnexus-review skill itself: a new "Swarm lanes" section names the four ci-persona lanes, defines when and how to dispatch them (parallel, one message, per-lane context and file slices), and owns the verification contract (lane reports are unverified claims; re-anchor, dedup, drop unanchored findings; lanes structure the work but never gate it). Any runner of the skill — the CI workflow or a local harness — now triggers the lanes from one canonical definition. The workflow prompt keeps only its CI-specific deltas: the lanes' trusted-control-SHA install provenance, the Task-tool dispatch surface, and the publisher's orchestrator-only context-evidence gate. Mirrors synced; 122 contract tests pass. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * feat(skills): add adversarial finder lane and critic gate to the swarm ci-adversarial-lens joins the parallel finder wave: it assumes the change is broken and constructs reachable failure scenarios — interleavings, hostile inputs, state corruption, abuse of newly exposed surfaces — each verified to a concrete entry point before it may be reported. ci-critic-lens runs last as a gate on the orchestrator's finished draft: it audits anchoring, concreteness, severity calibration, format conformance, and honesty, returning PASS or a numbered defect list with the smallest repair per item. The skill bounds it to two passes and the critic hardens the review without ever blocking it; the workflow inherits both lanes automatically through the wholesale ci-personas install. Mirrors synced across all three shipped trees; 122 contract tests pass. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * refactor(ci): workflow defers the whole swarm contract to the skill Now that the skill's Swarm lanes section owns dispatch, verification, the critic gate, and the fallbacks, the workflow prompt stops restating any of it. It contributes only what CI alone knows: the lanes' control-SHA install provenance, the concrete environment mapping for lane inputs (diff, manifest, head and merge-base checkouts, exact SHAs), and the one CI override — the publisher's context-evidence gate remains orchestrator-only. Analyze timeout gains headroom for the critic's sequential rounds (60 -> 75 minutes). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * fix(ci): dispatch swarm lanes via the Agent tool, not the renamed Task alias On the pinned Claude Code 2.1.214 the subagent-dispatch tool is `Agent` (`Task` was renamed to `Agent` in 2.1.63 and is now a legacy alias), and permission rules evaluate deny before allow. The workflow allowed `Task` and denied `Agent`, so the orchestrator could never dispatch a lane and every review silently fell back to the inline single-agent path while the text-only tests certified the broken config. Use `Agent` consistently: add it to --tools, allow it scoped to the six ci-personas (`Agent(ci-correctness-lens,...,ci-critic-lens)`), remove it from --disallowedTools, and update the prompt. Tests now match the scoped allowlist on the raw string (commas inside Agent(...) break a split) and assert Agent is no longer bare-denied. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * fix(ci): harden swarm permissions — allow Glob/Grep + merge-base reads, quarantine PR-head agents Three permission-hygiene gaps around the swarm dispatch: - Glob/Grep were in --tools but had no allow rule, so the lanes' declared tools could manufacture denied-tool errors; allow them (read-only, sandboxed by cwd + add-dir). - The prompt hands lanes the merge-base source checkout for deleted / rename-old symbols, but no Read rule covered it; add a scoped Read() allow (which grants access without triggering --add-dir agent discovery). - The --add-dir PR-head copy is scanned for spawnable agent definitions and the pinned runtime has no suppression env, so a PR could ship its own .claude/agents/*.md. Drop that subtree from the materialized copy after checkout-index (skills left intact), so only the trusted control-SHA personas can ever be dispatched. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * test(ci): pin the Agent allowlist to the ci-personas; require a dispatch canary A text-only assertion cannot prove the pinned CLI actually dispatches the lanes (print mode silently ignores invalid settings and does not validate Agent(type) content at parse time) — that is what let the original Task/Agent inversion pass CI. Two mitigations for the class: - A cross-consistency test asserts the six names in the Agent(...) allowlist equal the six ci-personas filenames and each persona's frontmatter name, so a rename or typo in any of the three fails without auth. - The activation checklist now requires the post-merge canary to prove a positive dispatch AND an unlisted-type refusal before enabling the trigger. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * fix(ci): bound swarm transcript volume with per-persona maxTurns The six lanes stream into the single execution transcript the publisher validates, but the personas carried no turn budget, so a large-PR swarm run could overflow the (hard-throw) transcript caps and brick a valid review. Bound each lane deterministically — finders maxTurns 12, the critic maxTurns 6 — which keeps the worst case (~2×(150+5×12+2×6) ≈ 444 messages) under the unchanged 1_000 cap, so no cap needs raising. A new test encodes that invariant: it fails if a persona's maxTurns is bumped without revisiting the cap. Applied byte-identically across all four shipped skill trees. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * test(ci): independently pin both sidechain evidence-gate guards The sidechain-exclusion guards at candidate registration and result acceptance were mutually redundant on realistic transcripts (a real sidechain turn carries parent_tool_use_id on both its call and result), so deleting either guard alone still passed the whole suite. Add two asymmetric cross-wired fixtures — a mainline call with a sidechain result (pins the acceptance guard) and a sidechain call with a mainline result (pins the registration guard), both expecting missing_graph_evidence. Mutation-verified: deleting either guard alone now reddens the suite.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * docs: record the review-agent swarm capability (AGENTS.md, CLAUDE.md, reviewer-swarm README) Reflect the shipped swarm in the standing docs: bump AGENTS.md to 1.14.0 and CLAUDE.md to 1.8.0 with changelog rows, extend the gitnexus-review description to mention the ci-personas swarm lanes, and refresh the reviewer-swarm README so its differentiator names the real distinction (interactive on-demand swarm vs the CI review agent's in-workflow lanes) now that both run swarms. No CHANGELOG.md edit (feature-PR rule). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * fix(ci): close pre-push review findings on the swarm permission change Adversarial review of the fix diff caught two issues introduced by the permission-hygiene commit: - Bare Glob/Grep in --allowedTools are separate tools that the Read()-scoped path denies (/proc, github.workspace, ...) do not cover, opening an undenied read path to the raw checkouts and host paths via a prompt- injected lane. Drop the bare allow — under dontAsk they stay denied by omission; lanes read via the scoped Read() rules and the graph MCP. - The agents quarantine removed only the add-dir root's .claude/agents; make it recursive so a nested (e.g. monorepo subpackage) .claude/agents cannot survive and be discovered. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * feat(ci): post an "in progress" marker while the review swarm runs Swarm reviews can take up to 75 minutes, and until now the PR showed no sign a review was running. Add a dedicated write-scoped `acknowledge` job that, under the same authorization gate as analyze, upserts a per-PR "🔄 GitNexus review in progress" sticky comment linking to the live run (and reacts 👀 to the trigger comment); the publisher removes that marker when the review — or a clean failure — posts. The marker lives in its own job so the model-facing analyze job stays secretless and read-only: it cannot post to the PR, so per-lane live progress isn't exposed there — the marker is a binary "running" state with a link to the Actions run where lane-by-lane progress is visible.

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(ci): install root and shared node_modules for the evolution benchmark The first real workflow_dispatch of the skill-evolution loop failed at task binding: capture_task_dependency_binding aborted with SandboxError: sandbox_copy path is unavailable: node_modules: No such file or directory The benchmark tasks sandbox-copy node_modules from three locations (tasks.scenarios.yaml) — the monorepo root, gitnexus-shared, and gitnexus — mirroring a full dev checkout. The install step only ran `npm ci` in gitnexus/, so the root and gitnexus-shared node_modules never existed and the loop died before any agent ran. Install all three (root, then build gitnexus-shared, then build gitnexus), matching the per-package install in ci-tests.yml plus the root deps the tasks require. A new contract test pins all three installs so this fails in CI rather than on the next real run — the same guard the workflow's other two P1 fixes got. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Va5uu9Ar3e45QZ5xFsG4AZ * fix(ci): only add the missing root install; the subpackage steps already exist The initial fix redundantly rebuilt gitnexus-shared and gitnexus inside the gitnexus step — but the workflow already builds both in their own dedicated steps. Only the monorepo root node_modules was missing. Add a single "Install monorepo root dependencies" step and leave the two subpackage build steps untouched, so the benchmark's root sandbox_copy resolves without double-building.

On 2.1.214 the permission resolver unconditionally forces permission mode to "default" whenever CLAUDE_CODE_SUBPROCESS_ENV_SCRUB is set — `--permission-mode dontAsk`, settings `permissions.defaultMode`, and `autoAllowBashIfSandboxed` are all ignored for the mode decision. The proposer runs headless `-p --bare` where Bash is its only writable tool (it writes the candidate overlay); under forced "default" Bash was no longer auto-approved, so the session blocked. We cannot set ENV_SCRUB=0 (it scrubs the Anthropic auth token from the sandboxed proposer's Bash subprocesses). Instead, align with the forced mode: pre-approve the proposer's exact tool surface via settings `permissions.allow` (["Read","Grep","Glob","Bash"]) — under "default" a tool runs without a prompt iff it matches an allow rule — and stop requesting a non-default mode so no warning fires. ENV_SCRUB and the full sandbox filesystem/network lockdown are unchanged. The real-binary containment canary is updated to the new invocation (no --permission-mode) so the CI job is the authoritative empirical gate, and a fast unit assertion pins the new permissions.allow / absent defaultMode.

The actual JSON event stream (permission_denials, tool_use/tool_result, is_error) lives in stdout, which run_managed already captures as proc.stdout_tail -- it just never made it into the session's error_detail. Add it there, bounded and truncated the same way stderr_tail already is. It flows through evolve.py's existing whole-record redaction before being written to disk / the uploaded artifact, so this closes the diagnostic gap without a new blind CI dispatch: the next failure of this shape is readable directly from the artifact.

This repo's history has grown to 1144 tags (a v1.6.9-rc.N release-candidate series) out of 1650 total refs, exceeding oracle_assets.MAX_CLONE_REFS=1024 -- a fail-closed guard in sanitize_clone_for_hidden_oracles() that refuses to proceed unless it can enumerate and delete every ref before handing a sanitized snapshot to a benchmark session (so an agent can never discover oracle answers via a ref the sanitization missed). `ref` at every call site (evolve.py, runner.py, sanitized_graph.py) is always a bare SHA or the literal "HEAD", never a branch name, so `--single-branch --branch <ref>` isn't viable (git clone's --branch requires a name). Tags are never used by the checkout fallback or by sanitization's own delete-everything behavior, so dropping them via --no-tags removes the 1144-ref majority without touching branch-fetch behavior or the existing ref/origin-ref checkout fallback, and without weakening MAX_CLONE_REFS itself. Verified against the real repository (not just the test fixture): cloning /workspace (1650 refs, 1144 tags) via the fixed make_worktree() now produces a clone with 237 total refs and 0 tags.

The hint can only shrink the pool from the default (clamped to [floor, default]), so the 2GiB/80%-RAM cap and the GITNEXUS_LBUG_BUFFER_POOL_SIZE escape hatch (incl. 0) are preserved. With no hint set, resolveBufferManagerSize returns exactly what it did before. Motivation: LadybugDB eagerly commits the buffer pool at DB open, so the fixed min(2GiB,80%RAM) pool adds a measured ~2.8s to every analyze even on a 3-file repo (dominant on Windows). Sizing the pool to the graph lets small repos use the fast 64MiB floor while large repos keep the cap.

A small repo opens with the fast 64MiB floor instead of eagerly committing the full 2GiB pool. Measured on a 3-file repo (this box): analyze drops 4.78s -> 1.9s for both fresh and incremental, matching a forced 64MiB pool; the 2GiB path still reproduces the old 4.78s. This roughly halves the skills-e2e Idempotency hook (two analyze passes) that was timing out on Windows CI.

Introduce a distinct ADAPTIVE_POOL_FLOOR (256 MiB) for the hint clamp, kept separate from BUFFER_POOL_FLOOR (64 MiB), which still guards defaultBufferPoolSize on tiny-RAM machines; the hint is still clamped up to the machine default so it can never over-commit. This keeps the change as what it actually is — a large-repo optimization: GitNexus full analyze is 51s (2 GiB) -> 35s (adaptive ~414 MiB). Small repos now open COPY-safely at 256 MiB instead of the 2 GiB default (same wall time on Linux, where commit is lazy; the eager commit is far cheaper than 2 GiB on Windows). The reframed comments drop the earlier unrepresentative "3-file repo / 64 MiB fast" claim.

Every workflow_bench arm except baseline_nomcp needs Skill and/or GitNexus MCP tools, so every one of those sessions has been silently unable to invoke gitnexus-plan/work/ review or the CE comparator skills -- the last skill-evolution run (gen 0) scored 0/3 resolution on both arms across every task with error_kind "skill-not-invoked", not because the candidate was bad but because the harness could never invoke either arm's skill at all. Only baseline_nomcp keeps --bare (it explicitly wants zero Skill/MCP access anyway). The rest drop --bare and rely on ANTHROPIC_API_KEY alone; the sandboxed HOME has no OAuth/keychain state to conflict with it, and there's no committed .claude/settings.json in this repo for dropping --bare to newly pick up. Outside --bare the built-in toolset defaults to everything (WebFetch, Task, subagents, ...), and --allowedTools only pre-approves within whatever's available -- it doesn't narrow it. Added --tools for non-bare sessions so the intended tool scope is still enforced instead of silently widening.

Why: Strict OpenAI-compatible backends return vectors in the model's native size but reject an unfamiliar `dimensions` field, breaking `analyze --embeddings` against them. The var was parsed but never propagated, so `omit` was a no-op. How: Add `requestDimensions` to HttpConfig, return it from readConfig, and forward `config.requestDimensions` (not the validation-only `config.dimensions`) to `httpEmbedBatch`. Local dimension checks still use `config.dimensions`. Details: Coexists with the retry/pacing fields introduced upstream; both feature sets are preserved. Default behavior unchanged when REQUEST_DIMS is unset. Impact: gitnexus/src/core/embeddings/http-client.ts; README; unit tests. * fix(embeddings): name GITNEXUS_EMBEDDING_REQUEST_DIMS in its own config error Address the review findings on #2574. What: - A malformed GITNEXUS_EMBEDDING_REQUEST_DIMS now throws an error naming GITNEXUS_EMBEDDING_REQUEST_DIMS, not the sibling GITNEXUS_EMBEDDING_DIMS. - isHttpEmbeddingDimsError recognizes both leads, so the CLI still classifies the REQUEST_DIMS config mistake as a clean config error, not a stack dump. - Tests: numeric-override decoupling (DIMS=1024 validates the response while REQUEST_DIMS=512 is sent in the body), the omit aliases (none/off/false/0), and the malformed-value error path (which also pins the naming fix). - README documents the full accepted values: omit-aliases and integer override. Why: readConfig reused the DIMS error lead for the REQUEST_DIMS branch, so REQUEST_DIMS=garbage misdirected the operator to edit the wrong variable. The feature's actual decoupling and its non-omit inputs had no test coverage.

Change: Remove the Math.min(300, ...) cap, keep dynamic calculation. Effect: 280K-node repo: 300 → 1617 flows. * test: add regression for dynamic maxProcesses sizing (#2198) Verify that processProcesses honours maxProcesses > 300 without truncation. Addresses the optional follow-up suggested by @koriyoshi2041. * test: exercise computeDynamicMaxProcesses at the phase layer (#2198) Extract from the inline expression in so the regression test can exercise the function that actually contained the removed cap. The previous test called directly with , which passes regardless of whether the phase-level cap is present — never had the cap. The new test suite covers: - floor (20) for tiny repos - linear scaling in the 0–3000 range - growth past 300 for large repos (the actual regression) - explicit assertion that reintroducing Math.min(300, …) would fail Addresses review feedback from @azizur100389. --------- Co-authored-by: Ubuntu <ubuntu@localhost.localdomain> Co-authored-by: Gergő Magyar <gergomagyar@icloud.com> --- .../ingestion/pipeline-phases/processes.ts | 13 ++++++- gitnexus/test/unit/process-processor.test.ts | 37 +++++++++++++++++++ 2 files changed, 49 insertions(+), 1 deletion(-) diff --git a/gitnexus/src/core/ingestion/pipeline-phases/processes.ts b/gitnexus/src/core/ingestion/pipeline-phases/processes.ts index fd2f25cc8..462d1523f 100644 --- a/gitnexus/src/core/ingestion/pipeline-phases/processes.ts +++ b/gitnexus/src/core/ingestion/pipeline-phases/processes.ts @@ -25,6 +25,17 @@ export interface ProcessesOutput { processResult: ProcessDetectionResult; } +/** + * Compute the dynamic max-processes budget from the symbol count. + * + * Scales proportionally (symbolCount / 10) with a floor of 20. + * Prior to #2198 this was capped at 300 via `Math.min(300, …)`, + * silently truncating process detection on large repositories. + */ +export function computeDynamicMaxProcesses(symbolCount: number): number { + return Math.max(20, Math.round(symbolCount / 10)); +} + export const processesPhase: PipelinePhase<ProcessesOutput> = { name: 'processes', // `structure` supplies `totalFiles` (progress counter) without the spurious @@ -53,7 +64,7 @@ export const processesPhase: PipelinePhase<ProcessesOutput> = { ctx.graph.forEachNode((n) => { if (n.label !== 'File') symbolCount++; }); - const dynamicMaxProcesses = Math.max(20, Math.min(300, Math.round(symbolCount / 10))); + const dynamicMaxProcesses = computeDynamicMaxProcesses(symbolCount); const processResult = await processProcesses( ctx.graph, diff --git a/gitnexus/test/unit/process-processor.test.ts b/gitnexus/test/unit/process-processor.test.ts index 18d5c7be3..09600c6de 100644 --- a/gitnexus/test/unit/process-processor.test.ts +++ b/gitnexus/test/unit/process-processor.test.ts @@ -3,6 +3,7 @@ import { processProcesses, type ProcessDetectionConfig, } from '../../src/core/ingestion/process-processor.js'; +import { computeDynamicMaxProcesses } from '../../src/core/ingestion/pipeline-phases/processes.js'; import { createKnowledgeGraph } from '../../src/core/graph/graph.js'; import type { CommunityMembership } from '../../src/core/ingestion/community-processor.js'; @@ -522,4 +523,40 @@ describe('processProcesses', () => { expect(result.processes.length).toBeLessThanOrEqual(3); expect(result.stats.totalProcesses).toBeLessThanOrEqual(3); }); + + // Regression for #2198: the processesPhase dynamic sizing used to cap at + // Math.min(300, symbolCount/10).

Bumping @ladybugdb/core from 0.18.1 to 0.18.2 in this PR still installs into a 0.18.1 directory, so both hardcoded lookups came up empty and failed hard under GITNEXUS_REQUIRE_FTS=1 in CI (all platforms, shard 3). Add findInstalledFtsExtension() to discover the real installed file by scanning every version subdirectory, and use it from both test files.

Rather than pin Babel back to 7, adopt Node 22.18+ as the supported minimum: set engines to ^22.18.0 || >=24.11.0, matching Babel 8 exactly so the warnings resolve honestly with no dependabot ignore needed. @types/uuid@11 is a deprecated stub - uuid@14 ships its own types and no tsconfig references it.

From 7666a009f058630cd55d0daceaea162719f7e1d3 Mon Sep 17 00:00:00 2001 From: Claude <claude@anthropic.com> Date: Tue, 21 Jul 2026 11:04:37 +0000 Subject: [PATCH 54/91] fix(java): resolve E.CONST.method() enum-constant receiver dispatch (#2561) Calling a method on an enum-constant receiver (E.CONST.method()) emitted no CALLS edge. The receiver "E.CONST" is a two-segment compound receiver; resolveCompoundReceiverClass walks each dotted segment via the owning class scope's typeBindings map, but enum constants had no typeBinding, so the constant segment dead-ended and no target was ever resolved. #2555/#2558 gave bodied constants a first-class synthesized E$N class with an MRO that includes the host enum; this is the receiver-side follow-up. synthesizeJavaAnonymousClassDeclarations now emits a class-scope typeBinding for every enum constant's simple name -> its E$N class (bodied) or the host enum itself (body-less), reusing the exact mechanism a field declaration uses. The generic compound-receiver chain walk then resolves E.CONST.method() with no change to any shared scope-resolution code. Bodied dispatch (EnumConst.A.hook() -> EnumConst$1.hook#0) and body-less inherited dispatch (Plain.A.m() -> Plain.m#0) are covered by new tests in the existing java-enum-constant-body fixture; both were verified to fail against the pre-fix tree.

From 5549403082019a3f036dea082787698363b785fd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Gerg=C5=91=20Magyar?= <gergomagyar@icloud.com> Date: Tue, 21 Jul 2026 14:40:20 +0100 Subject: [PATCH 57/91] fix(eval): self-hosted skill-evolution runner + sandbox Python 3 trust fix (#2600) * fix(eval): move skill-evolution to a self-hosted runner and fix the sandbox's Python 3 trust gap GitHub-hosted runners hard-cap job execution at 6 hours, which is too short once a benchmark session actually invokes Skill/MCP tools for real (the --bare fix in #2584 means sessions no longer no-op). Move the job onto a self-hosted runner (5-day cap instead) and document the activation step in the workflow's own checklist. Validating the self-hosted run surfaced a real bug: gitnexus-plan sessions inside the bwrap sandbox failed with "planning must create or modify exactly one plan artifact; observed 0". Root cause: evidence-provenance.mjs's atomic plan-writer only trusts a Python 3 binary owned by root or by the current process. Inside this --unshare-user sandbox only the calling uid is mapped (root isn't), so the real, root-owned /usr/bin/python3 surfaces as the kernel's overflow uid and gets correctly refused as untrusted. Fix: provision a small, self-owned wrapper script (same pattern already used for shell-prefix) that execs the real interpreter, so the sandbox has a Python 3 candidate the existing trust check can actually accept -- without touching that security-sensitive validation logic at all. Also add visibility so this class of failure isn't quiet next time: report.md now shows why each row failed (error_kinds), not just resolved 0/1, and the benchmark now exits non-zero when an incumbent arm -- the currently-shipped skill -- resolves zero across every task, since that reads as a broken harness rather than a normal candidate miss. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(eval): close the broken_incumbent_arms zero-valid-runs gap; document runner exposure tradeoff Addresses the two MEDIUM findings from the gitnexus-review-agent on this PR (https://github.com/abhigyanpatwari/GitNexus/pull/2600#issuecomment-5033363096). broken_incumbent_arms required valid_runs > 0 before flagging an incumbent, so an incumbent that fails every run with an excluded-but-non-systemic error_kind (e.g. evidence-unverified, which the outage-streak breaker explicitly resets on rather than accumulates) never accumulated a single valid run and sailed through silently -- the exact quiet no-promotion outcome this guard exists to catch, and arguably worse than the some-runs-resolved-zero case since here nothing completed at all. aggregate() never marks an excluded/unverifiable row resolved=True, so dropping the valid_runs requirement and checking resolved == 0 alone correctly covers both cases. Added a test for exactly this all-excluded scenario, which none of the existing three did. Updated the workflow's own activation checklist to reflect what's actually true now (the gitnexus-evolution environment's branch policy and the self-hosted runner are both live, codified in infra/gitnexus-evolution/ in a companion PR) and documented the exposure-window tradeoff the review flagged: the runner is stopped between runs but not destroyed/recreated per run, so it isn't fully ephemeral. Stopping already bounds the exposure window to the job's own runtime on one day out of seven; full per-job ephemeral provisioning is a deliberate non-goal for a job that runs at most weekly, revisit if that changes. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * docs(eval): remove public infra/ pointers from the activation checklist PR #2603 (the Terraform codification this checklist pointed to) got closed -- publishing the exact IAM roles, security group rules, and self-hosted runner topology for a real, live AWS account isn't safe to do in a public repo, even with no literal secrets or resource IDs in the diff. The underlying AWS/GitHub setup is unaffected and still documented privately; this just removes the now-dangling references to a directory that won't exist in this repo. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * ci(actionlint): register the gitnexus-evolution self-hosted runner label actionlint rejected `runs-on: [self-hosted, linux, x64, gitnexus-evolution]` in gitnexus-skill-evolution.yml because it can't discover custom runner labels. Register it in .github/actionlint.yaml so the Workflow Lint check passes.

Add EnumConst.A.log() -> EnumConst.log#0, exercising E$N's @reference.inherits MRO arm end to end. - LOW: `bodiedName ?? hostEnum` conflated "body-less" with "name synthesis failed on a bodied constant" (reachable only on malformed/error-recovery trees), silently binding an overriding constant's receiver to the host enum — a wrong edge instead of no edge.

Rebaseline the java scope-capture fingerprint (a822cef9 -> d04298a9): the bench corpus IS test/fixtures/lang-resolution, so the new dispatchInherited fixture method shifts it (+6 capture groups); the logic change contributes nothing (confirmed by isolating the fixture-only fingerprint). java.test.ts 242 passed; measure.mjs --check PASS (14 languages); tsc/prettier/eslint clean.

Fix lives entirely in the mount construction: resolve `node` via shutil.which (correctly picks up wherever actions/setup-node put it, since its tool-cache dir is already on PATH by the time this runs) and bind it read-only to the same fixed sandbox path the two call sites already expect. Neither call site needed to change. Backward compatible with GitHub-hosted runners, where this resolves to the same path and binds a harmless no-op self-mount.

The second real workflow_dispatch run on the self-hosted runner (https://github.com/abhigyanpatwari/GitNexus/actions/runs/29840270554) failed immediately in the bubblewrap preflight: "bwrap: Can't create file at /usr/local/bin/node: Read-only file system" -- bwrap can't create a new mount-point file inside a tree it already bound read-only when the real path doesn't already exist there on the host, which is exactly the self-hosted case this bind exists to fix. Introduces SANDBOX_NODE (/opt/claude/node), a fresh path outside every tree _runtime_mount_args binds, following the same pattern SANDBOX_CLAUDE and SANDBOX_PYTHON3 already use. Updates the two real call sites (sanitized_graph.py, runner_sessions.py) to use the constant instead of the hardcoded literal, so the fix can't drift out of sync with itself again, and re-exports it from runner.py alongside the other SANDBOX_* names for the real-bwrap tests that reference it directly. Adds a real-bwrap test (gated behind GITNEXUS_REQUIRE_BWRAP_CANARY, same as the existing ones) that copies a real node binary to a path outside every bound tree and actually launches bwrap against it -- an argv-construction test alone can't catch a bwrap-level "Read-only file system" error, only a real invocation can, and that's exactly the gap that let #2607's version of this fix through review looking correct. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(eval): don't let the new real-bwrap test's node-mock break bwrap's own resolution CI caught this immediately: the new test_real_bubblewrap_runs_node_from_outside_the_bound_trees monkeypatched shutil.which to return None for anything but "node", but prepare_sandbox's own bwrap/claude resolution (_resolve_executable) goes through shutil.which too -- so the test broke bwrap discovery before the sandbox it's supposed to exercise could even be built ("SandboxError: required executable is unavailable: bwrap"). Delegate to the real shutil.which for every other name instead of blanket-returning None.

The comprehensive enumeration otherwise let a failing file contribute its entire line count as phantom 'applied' edits. failed_files still names every dropped file. Counts are now derived once from the reported set. - MED: hoist the word-boundary regexes out of the per-line loop (one compile each instead of one per line), reused by the apply loop. - LOW: apply loop reuses escapedOldName instead of recomputing the escape formula inline (removes a preview/apply drift risk). - Soften the in-code comment: enumeration gives per-call preview/apply consistency; the pre-existing two-read TOCTOU (external write between preview and apply) is out of scope and noted, not newly introduced. Tests: add a mixed graph-ref + text_search multi-file case (asserts per-file confidence and the never-downgrade guard, via a stubbed rg), and a partial-write-failure case (asserts only landed files are reported).

Reproduced directly on the runner (SSM, matching the real sandbox settings exactly, including enableWeakerNestedSandbox): a single trivial "say OK" prompt -- no real task, no real API key even -- is enough to make Claude Code create a synthetic package.json/lockfiles/node_modules, a full set of .env variants, and .claude/agents, .claude/commands, .claude/.cc-writes in the workspace on every single session. None of this is something the model decided to write; it's Claude Code's own internal bootstrap for running inside an already-sandboxed environment, and it happens regardless of task or prompt. enforce_phase_workspace (the planning-phase boundary check: verify the plan session touched only its one plan doc) already excludes .git for exactly this class of reason -- harness/tool noise, not substantive diff. Extends the same exclusion to the empirically-observed bootstrap set. workspace_snapshot has exactly one use (this check, confirmed via every caller), so widening its exclusion list can't hide anything in some other context that actually cares about these paths changing.

Record the file identity {ino, mtimeMs, size} on each PoolEntry at open, and re-stat in initLbug: unchanged → reuse; changed & idle → closeOne + reopen the new file; changed while a query is in flight → serve the current handle (a later idle initLbug reopens, since closing an in-use connection is a native use-after-free). A stat failure (ENOENT during a full rebuild's unlink window) is treated as unchanged so the reader keeps its valid open inode until the new file appears. Mirrors the bridge cache's mtime-invalidation pattern. Step 1 of docs/plans/2026-07-21-...-analyze-atomic-swap-invalidation. The end-to-end reopen-on-swap path is exercised by the reader-during-rebuild integration test in a later step. * fix(analyze): publish a full rebuild via an atomic swap (POSIX) The full-rebuild path wiped the live index (wipeLbugDbFiles(lbugPath)) and rebuilt it in place, so a concurrent MCP reader that opened mid-build could see an empty/half-loaded DB, and a crash between the wipe and the end-of-run left the index destroyed (recoverable only by --force). Build the fresh index at <lbugPath>.new and swap it over the live index in one atomic rename at the end. All DB work flows through the singleton connection, so only initLbug/wipeLbugDbFiles take the temp target; the close already checkpoint-consolidates the build to a single file (verified: no residual .wal/.shadow), so the rename publishes a complete index in one step. A reader opening mid-build only ever sees the previous complete index; a reader holding the old inode keeps a consistent stale snapshot until the pool re-opens onto the new one (the pool staleness invalidation from the prior commit). On failure the swap is skipped, leaving the previous index byte-for-byte intact. POSIX only: the common CLI/serve-worker analyze paths skip the native close (closeLbugBeforeExit, #2264) and leave the build handle open at swap time. POSIX renames an open file cleanly; a same-process open handle blocks the rename on Windows, so Windows keeps the current in-place behavior (buildPath === lbugPath) until that is resolved. The Windows atomic swap and a deterministic concurrent reader-during-rebuild test are deferred follow-ups. Steps 2b + partial 3 of docs/plans/2026-07-21-...-analyze-atomic-swap-invalidation. Integration test asserts the no-temp-leak + inode-swap invariants and the crash-safety guarantee (a load failure leaves the live index untouched). * test(analyze): end-to-end read-pool reopen after an atomic swap Adds the deferred reader-during-rebuild / pool-reopen integration test: analyze v1 -> read pool serves it -> rebuild with a renamed function (atomic swap) -> the same repoId's initLbug detects the swapped inode and re-opens the pool onto the new index. Asserts the pool sees the renamed function and NOT the stale v1 name, exercising #1 (invalidation) and #2 (swap) together end to end. * fix(lbug): bound pooled read queries with setQueryTimeout The read pool relied only on a JS-side Promise.race (QUERY_TIMEOUT_MS) that frees the waiter but leaves the native call running. Set the engine-level setQueryTimeout on every pooled connection so a pathological query is bounded at the source too. * fix(lbug): name the held-open cause for WAL checkpoint failures (#2599) A WAL-checkpoint IO error that also carries a busy/lock signal means another handle (a gitnexus mcp server, or this process's own reader) holds the store open, not a disk fault. Add isLbugCheckpointBusyError (reusing the tested isDbBusyError keyword set) and, when the checkpoint driver exhausts its retry budget on such an error, annotate the surfaced error with the actionable held-open cause instead of a raw IO string. Note: overlaps in-flight work on repro/issue-2599-windows-wal-checkpoint; bundled here at the maintainer's request. * feat(analyze): opt-in atomic incremental + best-effort Windows swap Extends the atomic-swap publish (POSIX full rebuild) to two more cases: - Windows: the swap now applies when a real close is safe to release the build handle before the rename — i.e. non-pdg runs (windowsSwapOk excludes --pdg, the #2264 destructor-crash case), forcing a real close on the swap path. UNVERIFIED on Windows (no Windows runner here); --pdg and any failure fall back to today's in-place behavior, so it can never corrupt. - Incremental (opt-in, GITNEXUS_ATOMIC_INCREMENTAL=1): copies the live index into the temp, applies the incremental delete/writeback to the copy, and swaps at the end. Off by default because the whole-file copy negates incremental's speed premise — kept behind a flag pending a benchmark. The escalation valve also targets the temp so an escalated write stays atomic. Integration test covers the opt-in incremental path end to end (no temp leak, the incremental change is reflected after the swap). * refactor(lbug): centralize the read-pool + bridge open-retry budgets The lbug-config retry registry documented the open/handle-release/query-time budgets but the read pool's LOCK_RETRY_* (pool-adapter) and the bridge's LBUG_OPEN_RETRY_* (group/bridge-db) kept private copies that could drift. Move both into the registry as exported constants (POOL_OPEN_LOCK_RETRY_*, BRIDGE_OPEN_RETRY_*) and alias the local names to them — one tuning surface, no behavior change. * fix: address CI regressions from the bundled follow-ups - setQueryTimeout: guard the call so test doubles that don't model the engine method don't break connection creation. - atomic swap: skip the rename when the build produced no DB at buildPath (an empty repo / mocked pipeline) instead of throwing ENOENT. - #2599: don't wrap the checkpoint error in the driver (it hid the IO signature the CLI's --wal-checkpoint-threshold hint keys on); name the held-open cause at the CLI instead, beside that hint, keeping the original error intact. - retry consolidation: revert to documentation-only — moving the pool/bridge budgets into lbug-config broke every explicit lbug-config test mock. The registry now catalogues all budgets with their in-file locations. - analyze-wal-checkpoint-failure test: block both lbug.wal.checkpoint and lbug.new.wal.checkpoint, since a full rebuild now checkpoints the temp. * fix(analyze): publish the swap before stamping meta; identity-gate the reader (#2614 F1) Review found a HIGH regression: the full-rebuild wrote the freshness stamp (saveMeta, indexedAt=T_new) BEFORE the atomic swap, so a concurrent MCP reader that reinited in the saveMeta->swap window opened the OLD inode, recorded observed=T_new, and then never reinited again (ensureInitialized returns early on 'current') — serving the pre-rebuild graph indefinitely. The build-into-temp change inverted the pre-PR invariant that 'meta shows T_new' implied 'lbugPath holds T_new data'. Two coordinated fixes: - run-analyze: move the final saveMeta AFTER the swap, so meta.indexedAt only becomes visible once lbugPath resolves to the new inode. Verified nothing in the span reads on-disk meta and registerRepo writes only the registry. Leaving the dirty flag set across the swap also improves crash-safety. - local-backend: the reader staleness gate now also compares the lbug file IDENTITY (ino/mtime/size), reiniting on an inode change even when meta.indexedAt is unchanged. This closes the swap-window latch and covers the in-place incremental case — and is what actually makes the pool's dbIdentity net reachable for the MCP reader (the indexedAt gate otherwise bypassed it). * fix(lbug/analyze): WAL-aware incremental, residual-sidecar reconcile, Windows opt-in, #2599 anchor (#2614 F2-F4) Review remediations: - F3: gate atomic incremental on a CLEAN live index (inspectLbugSidecars) — the main-file-only copy would drop an orphan .wal's delta; fall back to in-place. - F4: on the swap, MOVE a residual <buildPath>.wal/.shadow beside the published index (not orphan it) so a swallowed final checkpoint's delta is replayed. - F2: record identity on the shared read-only Database and warn when a cached handle is reused after its on-disk index was rebuilt while another consumer holds it (unreachable via MCP — one consumer per lbugPath; a complete fix needs per-inode handles, documented). - Windows swap: opt-in (GITNEXUS_ATOMIC_WINDOWS_SWAP=1), default off — the forced real close re-bets an unproven #2264 assumption and can't be verified without a Windows runner, so the default Windows path stays in-place. - #2599: anchor isLbugCheckpointBusyError to real held-open wording instead of isDbBusyError's bare .includes('lock') over a message that embeds the DB path (a repo under blockchain-app misclassified a disk fault as held-open). - Docs: corrected retry-catalogue budgets (linear, not exp) and the checkedOut>0 bound comment (load-bounded, not IDLE_TIMEOUT_MS). * test(analyze): cover the production close path in the atomic swap (#2614 F5) Adds a full-rebuild swap test with skipNativeCloseOnExit:true — the close path the CLI and serve-worker actually ship (build handle left open at swap time), distinct from the default real-close the other swap tests exercise. Asserts the POSIX swap still publishes a single consolidated lbug with no .new temp and no orphan sidecar. * test(analyze): give the follow-up git commits an inline identity (CI fix) The end-to-end reopen and atomic-incremental tests' second commits used a bare `git commit`, which fails on CI runners with no global git identity (empty ident name). makeRepo's initial commit already passes -c user.name/-c user.email inline; apply the same to the rename/change commits. No code change. * fix(mcp): route reader reinit through initLbug's active-query guard (#2614 review) Review found an active-query retirement race: LocalBackend.ensureInitialized detected an identity/stamp change and called closeLbug(poolKey) DIRECTLY, but closeOne closes the shared Database at refCount 0 regardless of checked-out connections. So a reader detecting the new generation could close the Database a concurrent query is still executing on — a native use-after-free. This bypassed the checkedOut>0 guard that initLbug itself has. Fix (delegate, not close directly): initLbug now returns whether it actually rolled the pool over; ensureInitialized calls initLbug (which serves the current handle while a query is in flight and reopens only when idle) instead of closeLbug. The observed IDENTITY is advanced only when the pool actually reopened — if a query was in flight, the identity stays divergent and the reopen retries on a later idle check rather than latching on the old handle. The observed STAMP advances regardless so a same-file stamp change can't loop. Old generation now stays alive until its in-flight queries drain (lazy rollover); new requests during the busy window share the old handle until the pool goes idle, then reopen. No parallel open-both-generations, but no UAF and no stale latch. --------- Co-authored-by: Gergő Magyar <gergomagyar@icloud.com> --- gitnexus/src/cli/analyze.ts | 9 + gitnexus/src/core/group/bridge-db.ts | 2 + gitnexus/src/core/lbug/lbug-config.ts | 36 +++ gitnexus/src/core/lbug/pool-adapter.ts | 117 +++++++++- .../src/core/lbug/wal-checkpoint-driver.ts | 3 + gitnexus/src/core/run-analyze.ts | 137 ++++++++++- gitnexus/src/mcp/local/local-backend.ts | 48 +++- .../integration/analyze-atomic-swap.test.ts | 220 ++++++++++++++++++ .../analyze-wal-checkpoint-failure.test.ts | 12 +- .../test/unit/checkpoint-busy-2599.test.ts | 34 +++ .../unit/pool-freshness-invalidation.test.ts | 91 ++++++++ 11 files changed, 683 insertions(+), 26 deletions(-) create mode 100644 gitnexus/test/integration/analyze-atomic-swap.test.ts create mode 100644 gitnexus/test/unit/checkpoint-busy-2599.test.ts create mode 100644 gitnexus/test/unit/pool-freshness-invalidation.test.ts diff --git a/gitnexus/src/cli/analyze.ts b/gitnexus/src/cli/analyze.ts index ab4b8e00d..3d4505b6e 100644 --- a/gitnexus/src/cli/analyze.ts +++ b/gitnexus/src/cli/analyze.ts @@ -18,6 +18,7 @@ import { boundedCheckpointBeforeExit } from '../core/lbug/shutdown-helpers.js'; import { getOsPageSize, isLbugCheckpointIoError, + isLbugCheckpointBusyError, isLbugPageSizeFrameError, isPageSizeAwareLadybug, isWalCorruptionError, @@ -1624,8 +1625,16 @@ const analyzeCommandImpl = async ( } if (isLbugCheckpointIoError(err)) { + // #2599: when the checkpoint IO error also looks busy/locked, another + // handle holds the store open — name that actionable cause alongside the + // threshold hint (the original error is preserved so the hint still fires). + const heldOpen = isLbugCheckpointBusyError(err) + ? ` Another process may hold the store open (a running \`gitnexus mcp\` server, or a\n` + + ` stale reader) — close other GitNexus processes on this repo, then retry.\n` + : ''; cliError( ` LadybugDB failed while rotating/removing WAL checkpoint files.\n` + + heldOpen + ` This can happen when auto-checkpoint runs at the default threshold (~16MB).\n` + ` Retry with a larger checkpoint threshold to reduce checkpoint frequency:\n` + ` gitnexus analyze --wal-checkpoint-threshold ${RECOMMENDED_WAL_CHECKPOINT_THRESHOLD}\n` + diff --git a/gitnexus/src/core/group/bridge-db.ts b/gitnexus/src/core/group/bridge-db.ts index 6d99174a2..15bb1fb15 100644 --- a/gitnexus/src/core/group/bridge-db.ts +++ b/gitnexus/src/core/group/bridge-db.ts @@ -1031,6 +1031,8 @@ const LBUG_OPEN_RETRY_PATTERNS = [ 'lock held by another process', ]; +// Cross-repo bridge RO open retry.

Signed-off-by: dependabot[bot] <support@github.com> * fix(spring-config): migrate YAML parsing to js-yaml 5 event API js-yaml 5 removed the loadAll `listener` callback, the EventType/State types, and DEFAULT_SCHEMA that spring-config relied on, breaking the build. Rebuild the per-key line tree from parseEvents()/constructFromEvents() (positions are source offsets → mapped to lines), apply the `<<` merge tag via CORE_SCHEMA.withTags(mergeTag) (CORE alone leaves merge keys unexpanded), and resolve aliases by anchor name, which lets the object-identity WeakMap go. Behavior preserved: 9 unit + 8 integration spring-config tests pass, including merged-key declaration-line, cyclic-alias termination, and the depth budget. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(spring-config): restore v4 tag coverage, cover the v5 rewrite with tests Review follow-up for #2618. CORE_SCHEMA.withTags(mergeTag) was a narrowing, not a port: js-yaml 5 throws "unknown tag" on !!timestamp/!!binary/!!set/!!omap/!!pairs, and an unknown tag aborts the whole parse, which readConfigKeys swallows — so an application.yml using any of them would have gone from its full key set to zero keys, silently. Carry the rest of what DEFAULT_SCHEMA was; none of these tags can execute code. Add tests for every path the review flagged as uncovered: multi-document files, empty/comment-only/bare-`---`/bare-scalar documents, sequence-form merge keys, and explicitly tagged values (which fail against the one-tag schema, so they target the changed line). Clear the anchor map per document. It cannot change output today — constructFromEvents rejects a cross-document alias before the event tree is built, now asserted — but it keeps both layers on YAML's scoping rule. Drop the stale @types/js-yaml devDependency; js-yaml 5 ships its own types and tsc --noEmit is clean without it. Lockfile hand-edited because npm uninstall also strips every libc field. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * chore(autofix): apply prettier + eslint fixes via /autofix command * fix(spring-config): flatten !!set members, walk YAML iteratively Review follow-up for #2618. js-yaml 5 constructs `!!set` as a native Set; v4 built a plain `{member: null}` object. Object.entries of a Set is empty, so a tagged set collapsed to a bare leaf key and lost every member. Enumerate the Set instead. Sets arrive as mapping events with key/value scalar pairs, so member lines resolve through the usual lookup. !!binary and !!timestamp are unaffected — both are scalar events and take the leaf path, which is why a Uint8Array never explodes into one key per byte. Convert findYamlMappingLocation and flattenYamlValue from recursion to an explicit stack. Children are pushed in reverse so pops happen in declaration order, preserving "first match" and `out` insertion order; `leave` frames release the cycle guard where the old `finally` did. The depth budget still throws at the same boundary with the same message. Cover the gaps the review named: !!pairs (both duplicate entries survive), anchor-name reuse resolving to the nearest preceding declaration, and marker-only leading documents staying index-aligned across the two streams. buildYamlEventTree keeps no node budget by design — one node per event over an already-materialized array, bounded by MAX_CONFIG_FILE_BYTES. The docstring now says so rather than implying MAX_YAML_TRAVERSAL_NODES covers it.

But Claude Code bootstraps into whatever directory it is running in, and the benchmark's task prompts cd into gitnexus/, so the same noise landed one level down as gitnexus/.claude/.cc-writes -- whose parts[0] is "gitnexus", so it was never excluded. In skill-evolution run 29861768554 that accounted for 13 of 18 sessions, each failing with error_kind plan-evidence-invalid and the identical error_detail "phase changed unauthorized workspace path(s): gitnexus/.claude/.cc-writes". The same code path also guards the review phase (runner.py:499), so review arms hit it as review-evidence-invalid. Widening the whole set to match at any depth would be wrong: it also contains package.json, package-lock.json, node_modules and the .env family, and both gitnexus/package.json and gitnexus/.claude/settings.local.json are real tracked files whose edits must still be caught. So the root-anchored rule is unchanged, and a second narrow rule matches only the entries Claude Code itself creates inside a .claude directory (.cc-writes, agents, commands) at any depth -- never .claude itself. The predicate moves into _is_bootstrap_noise so it is directly testable. It is still evaluated before pending.append, so an excluded directory is never descended into. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(eval): mount the node install prefix so npx and npm resolve in the sandbox _runtime_mount_args bound only the `node` binary itself to SANDBOX_NODE. npm and npx are not standalone binaries -- they are symlinks into ../lib/node_modules/npm/bin/*-cli.js -- so the install prefix carrying both bin/ and lib/node_modules has to be mounted for them to resolve at all. On GitHub-hosted images node lives in /usr/local/bin, whose prefix (/usr/local) is already inside the wholesale /usr read-only bind, so npm and npx came along for free and the gap stayed invisible. A self-hosted runner's actions/setup-node installs into its own tool cache, outside /usr, so only the single node file was bound. Every task's verify command is "cd gitnexus && npx tsc --noEmit && npx vitest run <test>", so in skill-evolution run 29861768554 all 18 of 18 result records carried the identical verify_output "/bin/sh: 1: npx: not found" -- no run could resolve regardless of model output. It reached the model too: the session transcripts show 12 "npm: not found" failures, with gitnexus/scripts/build.js dying on `npm ci` with status 127. Binds Path(node_bin).resolve().parent.parent read-only at /opt/claude/nodejs, a fresh target outside the already-read-only trees (same constraint that put SANDBOX_NODE under /opt/claude), and adds its bin/ to SANDBOX_PATH. The bind is skipped when the prefix already sits inside /usr, /bin, /lib or /lib64, so the already-covered case does not widen the mount surface redundantly. SANDBOX_NODE is deliberately unchanged -- sanitized_graph.py and runner_sessions.py invoke it directly. SANDBOX_PATH is now derived from SANDBOX_NODE_PREFIX so the two cannot drift, and the minimal-mounts probe asserts against the constant instead of a duplicated literal. The real-Bubblewrap npx canary lives in test_proposer_sandbox.py deliberately: test_workflow_bench.py pins the set of files carrying the canary marker, and it runs in the eval-containment-linux job, where actions/setup-node also installs into the tool cache -- so the canary exercises the real failure shape. Combines plan steps 3-5 into one commit: the mount, SANDBOX_PATH and the pinned probe assertion are one behavioural change, and splitting them would leave a commit whose asserted PATH disagrees with the mounted reality. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(eval): only bind a verified node prefix, and stop excluding .claude/agents Addresses two findings from the branch review of the two preceding commits. 1. The prefix was derived as Path(node_bin).resolve().parent.parent with no check that the layout is really <prefix>/bin/node. Probed: /opt/bin/node bound ALL of /opt (every tool cache on a hosted runner), /mnt/tools/node bound /mnt, and a bare <dir>/node bound <dir>'s parent. That last shape is not hypothetical -- the pre-existing real-Bubblewrap node canary builds exactly it (tmp_path/toolcache/node), so eval-containment-linux would have silently read-only mounted the whole pytest tmp_path inside a containment test, passing while doing it. This function exists to keep the sandbox surface minimal, so an unrecognized layout now binds nothing extra and simply leaves npx unavailable, exactly as before the mount was added. 2. CLAUDE_BOOTSTRAP_ENTRIES also excluded "agents" and "commands" on the theory that they might appear nested too; only .cc-writes ever was observed. Every excluded name is a blind spot: once a .claude directory exists (gitnexus/.claude/settings.local.json is tracked) anything written under an excluded entry is invisible to the phase-boundary check, and Claude Code loads .claude/agents relative to its cwd -- which these tasks point at gitnexus/. Probed: a planning phase could plant gitnexus/.claude/agents/planted.md with the check reporting nothing, then the work phase reads it. Narrowed to .cc-writes alone; extend the set from an observed failure, never pre-emptively. Re-probed after both fixes: the over-broad mounts are gone while a genuine tool-cache prefix carrying npm still binds; planted agents/commands content is caught again; gitnexus/.claude/.cc-writes (the real run-29861768554 failure) stays ignored; and edits to gitnexus/.claude/settings.local.json are still caught. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(eval): gate the node-prefix bind on a working npx, not on an npm directory The guard tested (prefix)/lib/node_modules/npm as a proxy for "this prefix supplies npx". Test the property actually required instead: a working npx sitting beside node in a real bin/ directory. .exists() follows the symlink, so a dangling npx correctly fails the check -- it would not survive the mount either. The "bin" name requirement stays, because it is what keeps the parent.parent derivation honest; an npx sitting directly beside node in a flat directory would make that derivation name the wrong prefix. This matters because the guard can silently disable the fix it guards: if a runner's layout failed the proxy check, the prefix would not be bound and npx would still be missing, reproducing the original failure with no signal. Testing npx directly means the guard can only pass when the bind will actually achieve its purpose. Validated against a real extracted Node distribution (the official nodejs.org tarball layout that actions/setup-node unpacks into the tool cache) staged at a tool-cache-shaped path: bin/node is a real file, bin/npx resolves to ../lib/node_modules/npm/bin/npx-cli.js, and the prefix binds while SANDBOX_NODE is preserved.

Vite transpiles a TypeScript config by writing <node_modules>/.vite-temp/<config>.timestamp-*.mjs before it loads anything, so against a read-only dependency mount vitest dies with EROFS before a single test executes: EROFS ... /workspace/gitnexus/node_modules/.vite-temp/vitest.config.ts.timestamp-*.mjs This is pre-existing and was masked: until #2627 the verify command died at `npx: not found`, short-circuiting the `&&` chain before vitest ran. Confirmed by reproducing it at that merge base with npx bypassed entirely (`./node_modules/.bin/vitest`), so it is independent of the node-prefix mount. Because it blocks the oracle as well as the authored-test verify, `resolved` stays 0/N without this. bwrap cannot create a mount point inside an already-read-only bind -- the same constraint that put SANDBOX_NODE under /opt/claude -- so overlaying a tmpfs only works if the directory already exists in the mounted bytes. It cannot be mkdir'd into the dependency snapshot after capture either: the snapshot is digest-bound and validate_dependency_binding fails closed on drift. So the empty directory is captured during dependency capture, before the manifest and both dependency digests are computed, making it part of the snapshot rather than an untracked mutation of it. The sandbox then overlays a tmpfs on exactly that path; everything else in the mount, and the whole workspace, stays read-only, and the overlay never reaches the host clone the credited patch comes from. Scoped to dependency mounts whose target basename is node_modules, so hidden oracle and skill mounts stay wholly read-only with no writable island. Note: this shifts sandbox_dependency_content_digest and sandbox_dependency_manifest_digest, so promotion evidence recorded before this change is no longer comparable. That is already true of any harness fix that changes what the sandbox exposes. Verified on the self-hosted runner through the real path -- TaskAssetCache .prepare -> stage_task_assets -> prepare_sandbox -> run_verify with the actual trivial-version-alias verify string: passed, 15/15 tests, no EROFS. Full eval suite there with GITNEXUS_REQUIRE_BWRAP_CANARY=1: 337 passed, 4 skipped. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(eval): only overlay .vite-temp where the mount source actually carries it The tmpfs overlay keyed purely on the mount target basename being node_modules, which also matched the trusted GitNexus runtime mount at /opt/gitnexus/node_modules. That mount's source is the built runtime and does not carry a .vite-temp, and bwrap cannot create a mount point inside an already-read-only bind, so the containment CI job failed: bwrap: Can't mkdir /opt/gitnexus/node_modules/.vite-temp: Read-only file system FAILED test_real_bubblewrap_runtime_mount_imports_cli_without_exposing_checkout My runner probe only exercised the dependency-mount path, so it missed this. Gate the overlay on the mount SOURCE actually containing the directory rather than on the target name. task_assets.py captures .vite-temp only into dependency-snapshot node_modules, so the overlay now fires exactly there and never on the runtime mount -- and the gate is correct by construction, since a tmpfs can only overlay a mount point that already exists in the bound bytes. Adds a regression test for a node_modules mount whose source has no captured .vite-temp (the runtime-mount shape) getting no overlay, and updates the positive test to create the directory in its mount source. Verified on the self-hosted runner: the exact failing test now passes, and the full containment selection is 124 passed, 4 skipped.

Dropping the index is not an available recovery either — CALL DROP_VECTOR_INDEX is itself a VECTOR-extension function and is undefined in exactly that state. Add a single primitive that loads VECTOR under the analyze install policy and, only when that fails, reads CALL SHOW_INDEXES (which works without the extension) to decide whether an index actually exists to trip over. No call sites yet. Refs #2623 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(lbug): pin the #2623 VECTOR gate for embedding-row DML Three cases: no index + VECTOR unavailable stays safe (no needless escalation); index present + VECTOR unavailable is reported blocked AND the raw deleteNodesForFiles genuinely throws 'extension is not loaded' (proving the hazard is real, not theoretical); index present + VECTOR loadable is safe, the delete works, and the HNSW index survives — the invariant run-analyze relies on when it keeps the index across a surgical incremental run. Refs #2623 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(analyze): load VECTOR before the incremental writeback touches embedding rows Incremental analyze died on every content change once a repo had built code_embedding_idx: Analysis failed: Binder exception: Trying to delete from an index on table CodeEmbedding but its extension is not loaded. The surgical writeback's first statement is deleteNodesForFiles' CodeEmbedding join-delete, but nothing on that path loaded VECTOR until Phase 4 — so the engine refused the delete. This is an ordering defect, not an environment one: it reproduces on machines where VECTOR loads fine. The dirty-flag recovery then forced a full rebuild on the next run, which is why it read as 'just slow'. Call ensureEmbeddingRowDmlSafe() once, before the escalation gate and before any row is touched — the same 'index lifecycle before row DML' seam dropSearchFTSIndexes occupies for FTS (#2589). Unconditional, because a DB carrying the index from an earlier --embeddings run hits the same wall on a plain incremental run. When VECTOR truly cannot load the table is immutable (the index cannot be dropped without the extension either), so the run falls through to the existing wipe-and-COPY escalation with a message naming cause, consequence and remedy. Fixes #2623 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(analyze): pin the #2623 VECTOR-before-embedding-DML ordering end-to-end Sibling of the #2589 FTS drop-before-delete suite, same shape: drive the real runFullAnalysis incremental path over a real git repo and a real LadybugDB, seed real embedding rows, build the HNSW index, then assert the index state at the exact moment deleteNodesForFiles is invoked. Both cases were confirmed to discriminate — with the run-analyze change reverted they fail with the reported 'Trying to delete from an index on table CodeEmbedding but its extension is not loaded', and pass with it: - surgical path: the run completes, the index is still present AND extension_loaded at delete time, exactly one row per nodeId survives, and the untouched file's rows are preserved - blocked path: with GITNEXUS_LBUG_EXTENSION_INSTALL=never the run escalates to a full DB write and says so, instead of crashing Also applies prettier's reindent to the run-analyze log ternary. Refs #2623 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs(lbug): cite the pinned LadybugDB version in the #2623 probe note The probe matrix behind ensureEmbeddingRowDmlSafe was first recorded on 0.18.0, but gitnexus/package-lock.json pins 0.18.2 (#2587). Re-ran every case on 0.18.2: refused DELETE, refused CREATE, SIGSEGV on SET, DROP_VECTOR_INDEX undefined, DROP TABLE refused, SHOW_INDEXES readable with extension_loaded intact. Identical on both, so the design is unchanged — only the citation was wrong. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(analyze): preserve embeddings across the VECTOR-blocked rebuild, and check the catalog before loading Three follow-ups from reviewing the fix itself. 1. Data loss on the blocked path. Escalating wipes the DB files, and Phase 3.5 restores embedding rows from cachedEmbeddings — which deriveEmbeddingMode only populates when meta.stats.embeddings > 0. A DB holding embedding rows that its meta does not account for therefore had every vector destroyed silently by a rebuild it never asked for. Probe on a 3-file repo: 3 rows before, 0 after, no warning. Read the rows before escalating (a plain MATCH, no extension needed) so the existing restore has something to restore, and say so in the log. The blocked-path test now asserts the seeded rows survive exactly once, and that assertion fails without this rescue. 2. Catalog before extension. ensureEmbeddingRowDmlSafe loaded VECTOR first and only read SHOW_INDEXES on failure, so every incremental analyze on a machine without VECTOR paid a bounded out-of-process INSTALL attempt plus an 'extension unavailable' warning — including repos that never built an embedding index and can never hit this bug. One local catalog read settles that case first; the load is attempted only when an index actually gates DML, or when the catalog cannot be read. 3. Dead branch. targetConn is always the module singleton there, so the isSharedSingletonConn ternary could never take its second arm. Collapsed to withConnLock. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(doctor): live-probe the VECTOR extension instead of printing the static platform capability Review finding on #2624 (MEDIUM), and exactly what #2623's reporter hit: doctor printed 'VECTOR index: available' — derived from a static platform check — while every incremental analyze on the same machine was dying on an unloaded VECTOR extension. The FTS line was switched to a live LOAD probe for the identical contradiction under #2374; VECTOR now gets the same treatment. probeVectorExtensionLoad shares the FTS probe's implementation (bounded, offline-safe, never runs the installer) and doctor's semantic-mode line now follows the probe, not the platform: without a loadable extension the vector index can be neither built nor queried, so search really is on exact scan. The load-error classifier's remedies are label-parameterized so the VECTOR row stops dispensing FTS-specific advice — 'run analyze --repair-fts' repairs FTS indexes only and was actively wrong for a missing vector extension. Default label stays 'FTS'; every existing caller and pinned remedy string is unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(lbug): remove the stale Windows VECTOR gate — the extension ships for win_amd64 The codebase categorically refused VECTOR on Windows (platform !== 'win32' in isVectorExtensionSupportedByPlatform, plus a hard early-return in loadVectorExtension) on the strength of an early-era report that in-process INSTALL VECTOR could SIGSEGV (#1365). That belief is stale, verified directly: - the extension server hosts win_amd64 VECTOR artifacts for every 0.18.x extension version — v0.18.0 and v0.18.1 both serve a real 14 MB PE32+ DLL (curl-probed; 'file' confirms PE32+ x86-64) - the pinned 0.18.2 core resolves its extension directory to 0.18.1 (strace-verified LOAD open()), so the pinned version's Windows artifact exists too - INSTALL now runs in a spawned child (installDuckDbExtensionOutOfProcess), so even a crashing installer kills only the child and degrades to unavailable — the original hazard cannot reach the parent process any more Windows now takes the same runtime path as every other OS: try LOAD, install out-of-process when policy allows, degrade to exact scan when it truly fails. The MCP semantic-search lane loses its static platform gate too — it always attempts the vector index and falls back to the exact scan on runtime failure, with a once-per-backend diagnostic naming the real error instead of a platform-policy message. isVectorExtensionSupportedByPlatform is deleted; getRuntimeCapabilities reports the platform capability as available everywhere and defers machine truth to the live probe. Windows CI is the enforcement: the vector suites skip visibly only when the extension genuinely cannot load, so green Windows lanes now actually exercise VECTOR instead of silently skipping by policy. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(lbug): pin the catalog-read-failure fallback in ensureEmbeddingRowDmlSafe Review finding on #2624 (LOW): the one branch where the gate cannot cheaply prove safety — SHOW_INDEXES itself erroring — was exercised only by inference. Force it with a Connection.prototype.query spy over the real DB: the catalog read fails, and the gate must fall through to actually attempting the extension load (asserted via the recorded statement stream) rather than guessing, returning true here because the extension is loadable. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(mcp): load VECTOR on the pool's shared Database so the semantic vector lane actually works Review finding on #2624 (MEDIUM): extension load scope is per-Database (probe-verified — LOAD on one connection enables QUERY_VECTOR_INDEX on every connection of the same Database), and the pool pre-warm loaded only FTS. So LocalBackend's vector lane has ALWAYS raised 'Catalog exception: function QUERY_VECTOR_INDEX is not defined' through the pool and silently fallen back to the exact scan — repos above the 10k exact-scan cap got empty semantic results. The serve path was unaffected (the embedding pipeline loads the extension itself). Mirror the FTS line at BOTH load sites — doInitLbug's pre-warm and initLbugWithDb's external-Database adoption — under the same load-only contract (the read pool never triggers a network install), tracked by a new SharedDB.vectorLoaded flag reset where ftsLoaded resets. The new pool test is discriminating and deliberately closes the writable core adapter before the pool opens: a shared/injected Database would inherit the VECTOR load from test seeding and pass either way, so the case forces the pool onto its OWN fresh read-only Database where only the pre-warm can make the lane legal. Verified: fails at the pre-fix tree with the exact Catalog exception, passes with the fix. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * ci: run the #2623 ordering suite on Windows/macOS and pre-install VECTOR alongside FTS Two review findings on #2624, both landing in existing seams: - scripts/cross-platform-tests.ts gains incremental-vector-extension-ordering .test.ts: the win32 VECTOR gate is gone in this PR, so the #2623 drop-ordering + blocked-path escalation must be proven on the windows-latest native addon, not just Ubuntu. (The review's claim that lbug-delete-nodes-for-files.test.ts was also missing was wrong — it has been on the roster since #2409.) - scripts/ensure-fts.ts now pre-installs VECTOR under the same best-effort auto-policy contract, so every sharded CI process LOADs from ~/.lbdb instead of racing its own bounded out-of-process INSTALL; the workflow's extension cache already covers it (path is the whole extension dir — key kept for cache continuity). The cross-platform job sets GITNEXUS_REQUIRE_VECTOR=1 beside GITNEXUS_REQUIRE_FTS so a genuinely unavailable VECTOR is a loud failure, never a silent skip. Windows/macOS cannot be executed locally; the PR's CI lanes are the proof for this commit. Linux smoke: ensure-fts.ts reports both extensions ready; all 79 roster entries resolve. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(pool): register loadVectorExtension in the pool unit-suite mocks The pool adapter's new loadVectorExtension import surfaced in four suites that mock lbug-adapter.js with explicit factories (vitest fails loudly on a missing mocked export). Register the export in each — resolving false where the suite's world assumes no vector, true where it mirrors FTS — and extend lbug-pool-fts-load.test.ts, the suite that owns pre-warm extension loading, with the vector pair: successful load cached per shared Database, failed load retried on the next open, both pinned to policy load-only. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(analyze): use POSIX literals for graph paths in the #2623 ordering suite First Windows CI run of this suite (it joined the cross-platform roster this PR) failed with 'Parser exception: Invalid input <MATCH (n:Function) WHERE n.filePath = '>' — path.join produces backslashes on Windows, and a backslash inside the seed helper's single-quoted Cypher literal breaks the parser. The graph stores repo-relative filePaths with forward slashes on every OS, so graph-side paths are POSIX literals now (the incremental-orchestration convention); path.join stays only for real filesystem access. The same Windows lane also proved the substance this suite exists for: lbug-vector-extension passed 7/7 on windows-latest — the extension installed, loaded, and built a real HNSW index there — and the pool vector-lane and DML gate suites passed too. This commit fixes the harness, not the fix.

Floor the dependency at ^0.18.3 and lock core + all five platform packages. Resurrect the caller-identity regression test from PR #2553 (closed as superseded by the upstream fix): it pins context()/impact() to exact caller IDs across CodeRelation sub-table pairs so any future predicate regression fails loudly. Note: with CREATE-seeded data the test also passes on 0.18.2 (the upstream repro needs COPY-written chunk layouts) — it is a behavioural pin, not a bug reproduction.
