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.

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 ??

Providers recognize their own syntax and emit JSON-safe `CallableFlowSite` facts (`seed`, `copy`, `alias`, `address`, `load`, `store`, `formal`, `argument`, and `invoke`) into `ParsedFile`; shared ingestion never branches on a language name. These always-on facts cross workers and the durable parse store, whose schema is bumped whenever their semantic shape changes. + +The emit stage defers only invocation sites proven to reference a flow cell. Ordinary receiver/free/reference passes still resolve direct callees first and record exact callee IDs by file/line/column. Property dispatch then runs before callable flow because a property-dispatched wrapper call can seed actual-to-formal propagation. The callable solver consumes those direct targets, propagates callable sets through lexical cells and formals, and emits `CALLS` at the real indirect invocation site with reason `callable-value-flow` (confidence 0.8 for a singleton, 0.7 for a bounded multi-target set). + +The solver is flow-insensitive but bounded: dependency-indexed work items rerun only when a cell they read changes; target/address sets cap at 32; a hostile fact graph has a finite work budget; overflow or budget exhaustion emits no partial `CALLS` and produces a structured warning. Lexical shadowing is function/block aware, invocation/constructor results are not reinterpreted as callable designators, and overload selection uses provider-supplied signature metadata. C/C++ additionally associate visible prototypes with unique definitions so actual-to-formal flow crosses translation units; the provider-owned `hasFileLocalCallableLinkage` hook prevents `static` declarations or definitions from leaking across files. C++ member-function pointers preserve parameter/cv shape, keep non-virtual targets exact, and expand virtual targets through `MethodDispatchIndex`/MRO. + +Property-key dispatch remains a separate conservative fallback. Its per-key fan-out cap is 32; capped keys synthesize no partial calls and are reported at warning level with language, skipped-key count, dropped key names (bounded), and cap; the count also travels in `RunScopeResolutionStats.propertyDispatchSkippedKeys`. + +Standalone (regex-based) providers such as COBOL participate via `ScopeResolver.scopeResolutionEdgeMode: 'callable-flow-only'`: `runScopeResolution` runs for them, but every ordinary emission path — heritage, interface implementations, receiver-bound, free-call fallback, reference/import edges, post-resolution hooks — is gated off, so their legacy phase (e.g. `cobolPhase`) remains the sole owner of structural edges and the callable solver's `CALLS` are purely additive. A callable-flow-only provider whose files emitted no callable facts exits early, before finalize, keeping the opt-in proportional to source scanning. + ### Optional CFG/PDG emission (`--pdg`, #2081–#2086) On a `--pdg` run the parse worker builds a per-function control-flow graph from the tree-sitter AST (`LanguageProvider.cfgVisitor`; TypeScript/JavaScript today) and serializes it onto `ParsedFile.cfgSideChannel` as plain data. Scope-resolution then emits the program-dependence layers from that side-channel **inside Phase 4 of `runScopeResolution`, while the disk-backed ParsedFile store is still live** — the only window where the worker-built CFGs are loaded (the store is cleared right after the phase returns). A standalone post-`mro` phase would read an empty store, so the emit deliberately lives in-phase, mirroring the `applyCaptureSideChannel` pattern. The opt-in is off by default (graph byte-identical), folded into the parse-cache key (a pdg-off warm cache is never reused on a `--pdg` run), and each layer is bounded by a per-function edge cap that logs any dropped edges. All layers are `BasicBlock → BasicBlock` edges in the single `CodeRelation` table, keyed by `type`; there is **no** `Function → BasicBlock` edge — the symbol↔block join is reconstructed from the BasicBlock id prefix + line span.

PROF output (`PROF_SCOPE_RESOLUTION=1`) splits `finalize` from `propagate` so quadratic regressions in the chain-follow surface independently. --- diff --git a/CLAUDE.md b/CLAUDE.md index 60d35a111..e94d4f667 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -1,10 +1,10 @@ -<!-- version: 1.3.0 --> +<!-- version: 1.7.0 --> <!-- Metadata: version, last reviewed, scope, model policy, reference docs, changelog. - Last updated: 2026-03-22 + Last updated: 2026-07-16 --> -Last reviewed: 2026-04-13 +Last reviewed: 2026-07-16 **Project:** GitNexus · **Environment:** dev · **Maintainer:** repository maintainers (see GitHub) @@ -37,11 +37,16 @@ If always-on instructions grow, load deep conventions via conditional reads (e.g - **This repository:** [AGENTS.md](AGENTS.md) (Cursor + monorepo notes), [ARCHITECTURE.md](ARCHITECTURE.md), [CONTRIBUTING.md](CONTRIBUTING.md), [GUARDRAILS.md](GUARDRAILS.md). - **Call & inheritance resolution:** See ARCHITECTURE.md § Scope-Resolution Pipeline.

Given `analyze --skills`, each generated community skill has a direct, namespaced directory below `.claude/skills/`, and the context-file table points to that exact file. -- AE3. Given existing unrelated project skills plus legacy GitNexus grouping directories, rerunning analyze preserves the unrelated skills, produces the direct GitNexus skills, and leaves no managed reference pointing at a legacy grouped path. -- AE4. Given `--skip-skills`, no standard `gitnexus-*` skill is installed or referenced, while generated community skill behavior remains available when `--skills` is also requested. - -### Success Criteria - -- All standard and generated skill files use Claude Code's documented direct-child layout. -- Generated context, return messages, help text, and tests contain no active references to `.claude/skills/gitnexus/` or `.claude/skills/generated/`. -- The canonical repository no longer ships the six standard skills or managed routing rows in the broken grouped layout. -- Repeated runs are deterministic and do not delete unrelated user skills. - -### Scope Boundaries - -- **In scope:** project-local Claude Code skill installation performed by `analyze`, repo-generated community skills, managed context paths, the repository's checked-in copies of the six standard skills, CLI/help copy, migration of known legacy outputs, and regression coverage. -- **Out of scope:** global `gitnexus setup` targets, plugin skill layouts, changing the six bundled skill bodies, or changing Claude Code itself. -- **Deferred to follow-up work:** relocating this repository's three extra hand-maintained nested `.claude/skills/gitnexus/` skills that are not installed by `analyze`; those are workspace configuration rather than the issue's six standard installer outputs. - -### Sources - -- GitHub issue #2433: `https://github.com/abhigyanpatwari/GitNexus/issues/2433` -- Claude Code skills documentation: `https://code.claude.com/docs/en/slash-commands` -- Related path-contract regressions: GitHub issues #1098 and #1381. - ---- - -## Planning Contract - -### Key Technical Decisions - -- KTD1. Treat `.claude/skills/` as the installation root and make each skill directory its direct child. This matches the official project-skill contract and avoids relying on recursive discovery that Claude Code does not document. -- KTD2. Keep the six standard names unchanged because they are already `gitnexus-*` namespaced. This preserves their intended invocation names while correcting only the filesystem layout. -- KTD3. Reserve a separate GitNexus-owned prefix for generated community skill names before writing them flat. This prevents a community such as `Cli` from overwriting `gitnexus-cli` and prevents common labels such as `auth` from replacing user skills. -- KTD4. Replace grouped-directory cleanup with ownership-bounded cleanup. Remove known standard legacy children and generated legacy output, or direct generated directories carrying the reserved prefix, but never recursively clear `.claude/skills/` itself. -- KTD5. Keep generation and documentation derived from the same `GeneratedSkillInfo.name` value so disk paths, frontmatter names, managed routing rows, and repeat-run cleanup cannot drift. - -### Assumptions - -- Issue #2433's request to check community skills includes fixing them in this PR rather than filing a separate follow-up. -- Legacy `.claude/skills/generated/` is GitNexus-owned because current code already deletes and recreates it on every `--skills` run; unknown siblings under `.claude/skills/` remain user-owned. -- Standard legacy cleanup is limited to the six bundled names under `.claude/skills/gitnexus/`; unknown children in that grouping directory are preserved. -- The exact generated-skill prefix may be refined during implementation, but it must be stable, GitNexus-owned, direct-child compatible, and non-conflicting with standard skill names. - -### Existing Patterns to Follow - -- `gitnexus/src/cli/setup.ts` installs globally scoped Claude skills directly under the target skill root and provides a path-contract precedent. -- `gitnexus/src/cli/ai-context.ts` already centralizes standard skill definitions, context table generation, skip semantics, and best-effort filesystem handling. -- `gitnexus/src/cli/skill-gen.ts` already owns community-name normalization, deterministic collision suffixes, output cleanup, frontmatter rendering, and returned path metadata. -- `gitnexus/test/unit/ai-context.test.ts` uses temporary repositories to prove file layout and skip-mode behavior. -- `gitnexus/test/unit/skill-gen.test.ts` and `gitnexus/test/integration/skills-e2e.test.ts` cover generated skill metadata, file contents, idempotency, and end-to-end context references. - -### System-Wide Impact - -The change affects the user-visible filesystem contract of `gitnexus analyze`, generated AGENTS.md/CLAUDE.md content, CLI help output, and the invocation names of previously inert community skills. -It does not alter indexing, graph storage, MCP APIs, global setup targets, or runtime analysis behavior. - -### Risks and Mitigations - -- **Accidental user-skill deletion:** Scope cleanup to known standard names, the prior generated output directory, and the new reserved prefix; add preservation tests with unrelated directories. -- **Standard/community collision:** Use distinct namespaces and assert representative `Cli`/common-label cases. -- **Path drift across surfaces:** Derive context rows from returned generated names and assert exact disk-to-doc parity. -- **Skip-mode regression:** Retain focused tests for normal, `--skip-skills`, `--skills`, and `--index-only` combinations. - ---- - -## Implementation Units - -### U1.

Objective - -`gitnexus analyze` on triton (repro: `GITNEXUS_MAX_FILE_SIZE=5120 … analyze --worker-timeout 60`) must complete without SIGABRT. Two stacked defects, both fixed: - -1. **Perf (trigger):** C++ scope-capture extraction is O(calls × args × treeSize) per file — `lib/Dialect/TritonInstrument/IR/FunctionBuilder.cpp` (194 KB, parses in 46 ms) burns **151 s** in the worker; `hip_prof_str.h` (`.h` → cpp provider) burns 116 s. Measured via `--cpu-prof` on the real dist worker `[verified]`. -2. **Crash (abort):** terminating a worker thread that is inside an N-API call — whether via pool shutdown, breaker trip, **or plain process exit** — makes the pending `Napi::Error` escape as an uncaught C++ exception → `std::terminate` → SIGABRT kills the whole CLI (workers are `worker_threads`, shared process). Reproduced 2/2 on origin/main, exit 134 `[verified]`; process-exit variant reproduced directly `[verified]` (§5a). - -Acceptance criteria: triton repro completes (exit 0); `FunctionBuilder.cpp` extraction drops from ~151 s to sub-second; no worker-pool or cpp-resolver test regressions. - -## 2. Current Behaviour - -Per-file worker flow (`parse-worker.ts` `processFileGroup`): parse → `query.matches` → `extractParsedFile` → provider `emitScopeCaptures` (`emitCppScopeCaptures` for `.cpp`/`.h` — `c-cpp.ts:435` maps both) `[verified]`. - -For every call-expression capture, `inferCppCallArgTypeClasses` (`cpp/captures.ts:929`, driven from `:325`) classifies each identifier argument via: - -- `lookupDeclaredTypeClassForIdentifier` (`:1133`) — linear scan of the enclosing scope's children per identifier `[verified]`; -- `lookupFunctionParameterTypeClass` (`:1182`) + `findEnclosingFunctionParameter` (`:1200`) — walk up + param scan per identifier `[verified]`; -- **`isKnownEnumName` (`:1248`) — walks to the AST root and full-tree DFS for `enum_specifier`, per identifier argument** `[verified]`. CPU profile: 87.7 s of 149.9 s inside it; self-time dominated by tree-sitter N-API accessors (`child`/`childCount`/`type`/`unmarshalNode`) `[verified]`. - -Crash path: idle-timeout/give-up paths all pass `'retire'` → `retireWorkerAfterTimeout` (`worker-pool.ts:1188`) defers terminate until the worker posts `sub-batch-done`/`result`/`error` (the #1848 fix) `[verified]`. But: - -- `parse-impl.ts:1123-1125` `finally { await workerPool?.terminate() }` → pool `terminate` (`worker-pool.ts:2025` awaits) → `terminateTrackedWorkers` (`:971-980`) — terminates every live AND retired worker unconditionally `[verified]`. -- `tripBreaker` (`:1303`) fire-and-forgets the same (`void terminateTrackedWorkers`, `:1312`) on breaker trip — including live workers that may be mid-native-parse `[verified]`. -- These are the ONLY two callers `[verified]` (grep; matches the graph's d=1). -- **Existing test `worker-pool-timeout-retire.test.ts:97` asserts the crash-causing contract**: a never-safe retired mock worker gets `terminateCalls === 1` after `pool.terminate()` (`:114-118`); `:155` asserts the same for breaker trips `[verified]`. Both flip intentionally under this fix. -- Run evidence: process died 12 s after the last retire log with no error-path output; the 2-file mini corpus (retired workers finish before shutdown) exits 0 `[verified]`. - -## 3. Relevant Architecture - -- Shared ingestion pipeline is language-agnostic (AGENTS.md): the fix stays inside the cpp language module (`languages/cpp/captures.ts`) and the generic worker pool; no `LanguageProvider` interface change. -- Precedent for exactly this bug class: Go scope-capture re-walk fix (#1848/#1915), Python (#1918), C++ ADL once-built index (#1990) — `languages/c/captures.ts:39-42` documents the pattern `[verified]`. -- The C provider has its own thin `emitCScopeCaptures` (164 lines, no arg-type-class inference) — not affected `[verified]`. -- Workers cluster (76 symbols, 65% cohesion) is self-contained; depth-3 upstream impact of the shutdown change stays entirely inside it `[graph]`. -- `parse-worker.ts:1362-1369` documents the group-catch trap: a throw escaping per-file processing makes the language-group catch drop every remaining file — any new bail path must be caught per-file, never thrown outward `[verified]`. - -## 4. GitNexus Findings - -- `impact {target: emitCppScopeCaptures, direction: upstream, maxDepth: 2}` → 0 dependents, LOW `[graph]`. **Graph/source discrepancy:** the real consumer is the provider-hook indirection (`c-cpp.ts:495 emitScopeCaptures: emitCppScopeCaptures` → `scope-extractor-bridge.ts:41 extractParsedFile`) which the call graph doesn't model. Source wins; internal signature changes are still safe (all hot functions are file-private). -- `impact {target: terminateTrackedWorkers, direction: upstream}` at depth 2 → d=1: `tripBreaker`, `terminate`; deepened at `maxDepth: 3, summaryOnly` → 13 symbols total (d1:2, d2:7, d3:4), risk LOW, all in the Workers module. Key output: `"direct": 2` — both d=1 dependents modified deliberately in §6-C and source-confirmed `[verified]`. -- Related tests located and read: `test/unit/worker-pool-timeout-retire.test.ts` (mock `TimeoutThenHealthyWorker` harness with `terminateCalls`/`unrefCalls` counters and a `delayed-safe-return` mode — supports the new scenarios without factory changes `[verified]`), `test/integration/resolvers/cpp.test.ts` + `c.test.ts` (golden equivalence gate), `test/integration/cpp-adl-benchmark.test.ts` (GITNEXUS_BENCH-gated; template for the new benchmark) `[verified]`. - -## 5. Statement-Level PDG Findings - -- `pdg_query {mode: controls, target: isKnownEnumName}` (28 edges): the DFS body (`:1253-1262`) is control-dependent only on the trivial `typeName === ''` guard (`:1249`, guard:true) and its own loop conditions — **no memoization or early-exit gate exists**; the full-tree walk runs unconditionally on every call `[graph]`, consistent with source `[verified]`. -- `pdg_query {mode: controls, target: terminateTrackedWorkers}` → 0 edges: straight-line, unconditional termination of both worker lists `[graph]`. The crash fix is precisely "add the missing control dependency" (safe-point gate). -- Performance-mode scan: the hot loop's N-API fan-out (`cur.child(i)` per node per DFS per identifier) is the marshalling hotspot (`unmarshalNode` 15.5 s incl.) `[verified via profile]`. -- Ordering constraint: `lookupDeclaredTypeClassForIdentifier` returns the **first** matching `declaration` in scope-child order, with no position filtering relative to the identifier — the replacement index must preserve first-declaration-wins and must NOT introduce use-before-decl filtering `[verified]`. - -## 5a. Deepen finding — A1 refuted empirically - -Driver test (`exit-with-busy-worker.mjs`, kept in scratchpad): main thread `process.exit(0)` five seconds into the real dist worker's extraction of `FunctionBuilder.cpp`, worker `unref()`d → **process aborts: `terminate called after throwing an instance of 'Napi::Error'`, exit 134** `[verified]`. Node tears down worker environments on process exit through the same terminate path. Consequence: "skip terminating unsafe workers and let the process exit" merely relocates the abort. The shutdown design must instead guarantee workers reach a JS safe point in bounded time before the process exits — this promotes the previously-deferred cooperative extraction deadline into scope (§6-D). - -## 6. Proposed Changes - -**A. Perf root-cause — per-file lookup index in `gitnexus/src/core/ingestion/languages/cpp/captures.ts`.** -Introduce a lazily-built, per-invocation index object created at the top of `emitCppScopeCaptures` and threaded through `inferCppCallArgTypes` / `inferCppCallArgTypeClasses` → the lookup helpers (all file-private; no exported API change): - -- `enumNames: Set<string>` — built by ONE root DFS on first `isKnownEnumName` query (lazy: files with no identifier args pay nothing). `isKnownEnumName` becomes a Set lookup. Behavior-identical: current code matches any `enum_specifier` name anywhere in the translation unit. -- `scopeDecls: Map<number /* scope.id */, Map<string, {typeNode, nameChild, stmt}>>` — per-scope declaration map built on first lookup in that scope by one pass over `scope` children, first-declaration-wins (skip existing keys). Replaces the per-identifier linear scans in `lookupDeclaredTypeClassForIdentifier` / `lookupDeclaredTypeForIdentifier` (`:1090-1131`). -- `fnParams: Map<number /* function node.id */, Map<string, param>>` — same treatment for `findEnclosingFunctionParameter`. - -Complexity: O(treeSize + identifiers) per file. Expected: 151 s → sub-second (parse itself is 46 ms). `classifyCppParameterType` / `normalizeCppTypeText` stay per-hit (cheap; memoizing them changes nothing observable). - -**B. New benchmark test — `gitnexus/test/integration/cpp-captures-typeclass-benchmark.test.ts`** modeled exactly on `cpp-adl-benchmark.test.ts` (`describe.skipIf(!GITNEXUS_BENCH)`): synthetic C++ file scaling call-sites × enums, asserts sub-quadratic scaling of the capture-emit phase. - -**C. Crash fix — safe-point-gated shutdown with bounded drain, `gitnexus/src/core/ingestion/workers/worker-pool.ts`.** (Redesigned after §5a.) - -- **C1 (gate):** extend `RetiredWorkerRecord` with `safeToTerminate`, set exactly where `terminateWhenBackInJs` fires today (`onRetiredMessage` for `sub-batch-done`/`result`/`error`, and `messageerror`). `terminateTrackedWorkers` terminates retired records only when safe; unsafe records keep their armed at-safe-point terminate listener. -- **C2 (bounded drain):** pool `terminate()` awaits unsafe retired records' safe-point terminate up to a cap (`GITNEXUS_WORKER_SHUTDOWN_DRAIN_MS`, default ≈ 30 s — comfortably above D's per-file deadline so the drain converges for the known class). On cap expiry: log a clear diagnostic naming the wedged worker + in-flight file and proceed (residual abort risk at process exit remains for truly-wedged native code, now rare and diagnosed). The breaker path (`tripBreaker:1312`) stays fire-and-forget — it must never block the dispatch rejection; its unsafe records drain when the pipeline's `finally` runs pool `terminate()`. -- **C3 (breaker-path live workers):** on breaker trip, live workers in `busySlots` (`:1154` `[verified]`) are routed through `retireWorkerAfterTimeout` instead of direct `terminate()` — same mid-native abort risk, same cure. Idle live workers terminate directly (parked in the JS event loop; safe). The normal post-parse `terminate()` still direct-terminates live workers — all idle by construction (jobs drained). - -**D. Cooperative extraction deadline (promoted from deferred Q2 by §5a) — `cpp/captures.ts`.** -Bound per-file wall time inside `emitCppScopeCaptures`'s match loop: check `Date.now()` against a soft budget (`GITNEXUS_CPP_CAPTURE_BUDGET_MS`, default ≈ 20 s; post-A one iteration is microseconds, so check granularity of every N=64 matches is ample). On breach: **return** partial captures accumulated so far + `reportWarning` naming the file — never throw (the group-catch trap, §3). This guarantees cpp extraction returns to JS in bounded time, which is what makes C2's drain converge and process exit safe. Generic all-language budget remains a deferred follow-up (§12). - -## 7. Implementation Sequence - -1. **cpp captures index (A).** Build the index type + lazy constructors; convert `isKnownEnumName`, `lookupDeclaredType{Class}ForIdentifier`, `lookupFunctionParameterType{Class}`, `findEnclosingFunctionParameter`; thread from `emitCppScopeCaptures`. Gate: `npx vitest run test/integration/resolvers/cpp.test.ts test/integration/resolvers/c.test.ts` passes unchanged. -2. **Benchmark (B).** Add the GITNEXUS_BENCH-gated benchmark; record before/after in the PR body (before: 151 s / 116 s from this plan). -3. **Extraction deadline (D).** Budget check + partial-return + warning; unit test with a tiny budget forcing the bail (assert warning emitted, remaining files in group still processed). -4. **Worker-pool shutdown safety (C1–C3).** Gate + drain + breaker routing. Update `worker-pool-timeout-retire.test.ts:97` and `:155` (both currently assert the buggy contract) and add: (i) `pool.terminate()` with a never-safe retired worker + tiny drain cap → resolves after cap, `terminateCalls === 0`, diagnostic logged; (ii) retired worker signals safe during drain → terminated, `terminate()` resolves promptly; (iii) breaker trip with busy live worker → retired, not direct-terminated. -5. **End-to-end validation.** Rebuild (`npm run build`); re-run the triton repro → exits 0, `FunctionBuilder.cpp` indexed (not quarantined); mini 2-file corpus completes in seconds; re-run the §5a exit-with-busy-worker driver against the built worker with D's budget lowered → clean exit. - -Steps 1–2 alone de-trigger #2432; 3–4 close the abort class. Each step leaves the tree green. - -## 8. Test Strategy - -- **Update:** `worker-pool-timeout-retire.test.ts:97` + `:155` — expectations flip to the new contract (unsafe ⇒ not terminated at shutdown; terminated at safe point). The mock harness supports this as-is `[verified]`. -- **Add:** benchmark (§6-B); three shutdown cases (§7-4); deadline-bail unit test (§7-3). -- **Regression:** resolver goldens `cpp.test.ts`/`c.test.ts` unchanged (equivalence gate); full `npm run test:unit`; `npm run test:integration` (carries its build via `pretest:integration`). -- **Edge cases:** file with enums but no calls (lazy index never built); duplicate declaration in one scope (first-wins preserved); use-before-decl in scope (still resolved — no position filter); anonymous enums (name-less `enum_specifier` excluded, same as today); breaker trip with mixed busy/idle live workers; drain cap = 0 (immediate proceed); deadline breach mid-file (partial captures kept, group continues). -- **Failure paths:** shutdown never hangs (drain is capped); deadline bail is a warning, never a group-dropping throw (§3 trap). -- **Verification commands (verified to exist):** `npm run build`, `npm run test:unit`, `npm run test:integration`, `GITNEXUS_BENCH=1 npx vitest run test/integration/cpp-captures-typeclass-benchmark.test.ts` — all from `gitnexus/`. - -## 9. Risk and Impact Analysis - -- **d=1 dependents of `terminateTrackedWorkers`** — `tripBreaker` (`:1312`), `terminate` (`:2025`): both modified deliberately; no other callers `[verified]`. Depth-3 radius stays pool-internal (13 symbols, Workers module) `[graph]`. -- **Behavioral-equivalence risk (A):** first-declaration-wins + position-free matching must be preserved (§5). Mitigation: resolver goldens + explicit edge cases. -- **Node identity:** key maps by `SyntaxNode.id` (stable within a tree); wrapper object identity is NOT usable (wrappers are recreated per access — a `WeakMap` would silently fail). -- **Drain-cap tuning (C2 vs D):** drain cap must exceed D's budget or the drain can expire while a worker is legitimately finishing its bailed file — defaults 30 s vs 20 s encode that; both env-tunable, relation asserted in a unit test comment. -- **Residual abort window:** a worker wedged in native code longer than the drain cap still aborts at process exit — now requires non-cpp pathological input (D bounds cpp) and is logged with the culprit file before it can happen. Accepted; full elimination needs child-process workers (out of scope, §12). -- **`emitCppScopeCaptures` consumers:** provider hook only; signature unchanged (D's budget read from env inside the module) — zero external surface. -- **Deadline false positives (D):** 20 s default is ~3 orders of magnitude above post-A extraction cost of the worst observed file; breach ⇒ degraded coverage for that file (warning), never a failed run. -- **Coverage change:** triton's `FunctionBuilder.cpp` was previously quarantined; post-fix it indexes — strictly an improvement. -- **Concurrency:** the new index and deadline state are function-scoped per invocation (per file, per worker thread) — no shared state, no `clearCaches()` interaction. - -## 10.

Assumptions and Open Questions - -- **A1 — RESOLVED (refuted):** process exit with a native-busy unref'd worker DOES abort (§5a, empirical).

Definition of Done - -1. `GITNEXUS_HOME=<fresh> GITNEXUS_LBUG_EXTENSION_INSTALL=never GITNEXUS_MAX_FILE_SIZE=5120 node gitnexus/dist/cli/index.js analyze --worker-timeout 60` on triton-lang/triton exits 0 with no `Napi::Error`/SIGABRT, and `lib/Dialect/TritonInstrument/IR/FunctionBuilder.cpp` appears in the index (not quarantined). -2. Mini 2-file corpus (FunctionBuilder.cpp + hip_prof_str.h) analyzes in seconds (was 318.9 s). -3. The §5a exit-with-busy-worker driver, run against the rebuilt worker, exits cleanly. -4. Updated + new worker-pool unit tests green (including flipped `:97`/`:155` contract); resolver goldens (`cpp.test.ts`, `c.test.ts`) green unchanged; `npm run test:unit` and `npm run test:integration` green in `gitnexus/`. -5. Benchmark demonstrates sub-quadratic capture-emit scaling behind `GITNEXUS_BENCH=1`; deadline-bail test proves partial-return-not-throw. -6. No `LanguageProvider`/public API signature changes; no CHANGELOG edits. diff --git a/eval/tests/test_ce_plugin_runtime.py b/eval/tests/test_ce_plugin_runtime.py new file mode 100644 index

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.

For efficiency ranking, prefer a paid + run gated on `cost_usd`, or sum per-session usage from the transcripts + (`~/.claude/projects/<cwd-slug>/<session_id>.jsonl`, deduplicating events + that share one `message.id`). +- OpenRouter `:free` variants are rate-limited (~50 req/day on a fresh + account); local Ollama has no limits. +- Codex users: `codex exec --oss` runs local models for free too, but this + runner is Claude-Code-first; a codex engine is a straightforward extension + (parse its `--json` usage events). + +## Historical ground base (2026-07-11, Claude Code 2.1.207, unnamed model, n=1/cell) + +These figures predate mandatory model provenance and are retained only as +historical calibration.

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. Fixed by giving every +arm an isolated `git clone --no-local --no-hardlinks` with no object +alternates (agent-created refs and storage die with the clone); +the leaked branch was deleted and the cell re-measured.

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. Keep `verify` as a +model-visible authored-test quality signal, and add an independent `oracle` +whose source files live under `workflow_bench/oracles/`.

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.

Results are filtered into a bounded slice + (`references/pdg-slice.md`), never dumped. +3. **The agent verifies** (targeted line-range reads). Current source is + authoritative; graph results are navigation hints until verified. On + disagreement: trust source, record the discrepancy, recommend re-indexing. + +Token efficiency comes from the **context ledger** +(`references/context-ledger.md`): every query and read is recorded with the +question it answered, and nothing is re-fetched unless the source changed, a +contradiction surfaced, or one of the ledger's defined escalations applies +(summary→detail drill-down, ambiguity narrowing, a changed parameter answering +a new question).

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-<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.

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.

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 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/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?

Both expected values must + come from the same receipt. Deepen must load and bind that canonical path and + those original bytes through `read-plan` first. Snapshot, read, and + publication must pass the same strict generated-plan filename/date validator. +- §2/§5 quote source excerpts at most `max_snippet_lines` (30) lines each, and + only when the excerpt carries the argument. +- §4 findings each name the tool call they came from (tool + key args), plus a + one-line quote of the result when the plan leans on it — that is what makes + a tool claim auditable later. Stale-index or fallback-mode findings are + labelled as such. +- §6 changes may only name symbols the ledger marks `source_verified`. +- §7 steps are ordered by dependency and independently actionable — an + executor can stop after any step with the tree still coherent. Steps that + change output guarded by fingerprints, goldens, or recorded baselines + regenerate those artifacts ONCE, in the final step of the sequence — CI + judges only the tip, and per-step refreshes churn every intermediate + commit and re-drift as later steps land. +- §8 names real, located test files for updates; new tests get concrete + scenario lists (input → action → expected outcome). Verification commands + must exist AND be runnable: prefer the npm/CI script form that carries its + prerequisites (pre-hooks, builds) over invoking underlying binaries directly. +- §9 must account for every direct (depth-1) dependent the impact pass + reported. diff --git a/gitnexus/skills/gitnexus-plan/scripts/evidence-provenance.mjs b/gitnexus/skills/gitnexus-plan/scripts/evidence-provenance.mjs new file mode 100644 index 000000000..181d2120b --- /dev/null +++ b/gitnexus/skills/gitnexus-plan/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 ??

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.

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.

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.

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 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/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 ??
