fix(ci): stop the review agent rejecting its own graph-backed reviews (#2731)
* fix(ci): stop the review agent rejecting its own graph-backed reviews

The context-evidence gate only counted a `context` call when the call
itself passed `file_path` equal to a changed path. The review skill
teaches plain `context({name})`, so 17 of the 26 review-agent run
failures were complete, graph-backed reviews thrown away after full
model spend, with no log line saying which invariant failed.

Prove the evidence from the result instead: `status=found` plus a
`symbol.filePath` inside the repo-scoped changed-path set. Every other
check stays exactly as it was - strict JSON, orchestrator-only turns,
result ordering, duplicate tool-id rejection - and the `repo` argument
still selects the head or the merge-base path set.

Same failure inventory, smaller classes:

- rejection now logs why (in-scope, out-of-scope, sidechain, unresolved
  and off-path counts plus up to three sanitized paths), and the
  envelope error names the message count and first-message shape
- Glob/Grep leave the tool set: they were enabled through `--tools` but
  never allow-listed, so every lane call was denied and burned turns
- both pinned `npm ci` installs retry three times; one registry
  ECONNRESET killed a whole run
- the prompt matches the new contract and asks for the structured body
  even when the analysis is incomplete

* fix(skills): mirror the review-skill tool-set change into the shipped copies

The npm package, Claude plugin, and Cursor integration ship byte-identical
copies of .claude/skills/gitnexus-review, and the drift guard compares them.
Dropping Glob/Grep from the lane frontmatter and the SKILL.md sentence only
landed in the canonical tree.

* fix(ci): stop one junk context result discarding a proven review

Tri-review of this PR found that the previous commit fixed one spurious
rejection and created another. Widening evidence candidacy from "the call
that named a changed path" to "every orchestrator context call" also
widened the *strict-parse* surface: `contextResultProvesChangedPath`
throws rather than returning false, so a single malformed payload
anywhere in the transcript now discarded a review that an earlier call
had already proven. The MCP makes that reachable without any misbehaving
model - `GITNEXUS_MCP_DEFAULT_MAX_TOKENS=12000` truncates any context
payload over ~48 KB mid-JSON and appends a marker - and it also destroyed
docs-only runs that the `no_indexable_changed_symbols` mode exempts.

Reproduced by running the workflow's own embedded script on both trees:
a proving evidence call followed by one truncated exploratory call gave
`failure_code: null` on the base and `invalid_execution_transcript` on
the head; it is `null` again here.

- payload-shape failures are caught and counted (`malformedResults`)
  instead of thrown; transcript-structural invariants (envelope, tool
  shapes, duplicate ids, empty tool_result) still fail closed
- diagnostics gained the reasons they were blind to: errored results,
  results that arrived out of order or via a sidechain, unanswered
  in-scope calls, and malformed payloads. A rejection can no longer
  print an in-scope call with every reason at zero
- a deletion-only PR no longer registers head-scoped candidates that can
  never be satisfied: an empty eligible set is out of scope, not a result
  "outside the changed paths"
- the mandatory-body prompt clause now pairs with a required `complete`
  boolean. An incomplete analysis publishes its partial body labelled
  `incomplete_analysis` instead of passing as an accepted review
- `Agent(a,b,c)` is split into six separate `Agent(x)` rules: the pinned
  base action parses allowedTools with `.flatMap((v) => v.split(","))`
  (parse-sdk-options.ts at 3553f843), which shattered the grouped rule
  into `Agent(ci-correctness-lens`, four bare names, and
  `ci-critic-lens)` before the SDK saw it. Pre-existing and unproven at
  runtime, but the split form is correct under either reading and lets
  the header's dispatch canary actually prove something

* fix(ci): require a line range for context evidence

The tri-review's adversarial lane executed `context({name: 'AGENTS.md'})`
and had the result accepted: the gate checked only that the resolved
filePath was in the changed set, so a bare File node passed for a review
of that file's contents. The trusted prescan already defines an indexable
symbol as one with startLine and endLine, so require the same here.

Pre-existing rather than introduced by this branch, but it is the same
"what counts as proof" surface the rest of this PR tightens.

* fix(ci): close the remaining tri-review findings

Addresses every finding the tri-review left open after 0432214d and
1d9f2d75, across both engines.

Reliability and maintainability (Codex ce, ce-reliability, ce-maintainability):
- both pinned `npm ci` installs now call one shared
  `.github/scripts/npm-ci-retry.sh` instead of two near-identical 12-line
  blocks that differed only in a label
- each attempt runs under `timeout` (default 600s, overridable), so a slow
  registry can no longer crowd the model review out of the job's budget
- the helper distinguishes a timeout kill (124) from an npm rejection in
  its log

Test coverage (ce-testing, Codex swarm P3, ce-security, swarm test-ci):
- the retry helper is now exercised behaviourally with a stub npm: first-try
  success runs once, two failures recover on the third, three failures exit 1
- a non-string `symbol.filePath` is a clean reject, not a type error
- an adversarial resolved path (ESC, newline, `::set-output`, RTL override)
  is proven sanitized before it reaches the job log
- the envelope error's shape string is asserted
- an in-scope call whose result never arrives is counted, not silent
- install flags that keep the runtime inert (`--ignore-scripts`, `--prefix`,
  the lock-bound registry) are asserted against the helper they moved into

Correctness and clarity (risk-architect, ce-standards):
- the prompt now tells the model to prefer the uid form or pass file_path
  when a bare name could resolve into an unchanged file, which was the
  narrower off-path failure mode the gate rewrite left behind
- `contextResultProvesChangedPath` -> `contextResultProvesEligiblePath`,
  matching the set-membership contract its sibling was renamed for
- the transcript fixture's default no longer carries a `file_path` the gate
  ignores, which implied the opposite of the contract
- SKILL.md says "file reads" rather than naming a CLI-specific tool, per
  the CLI-neutrality rule in AGENTS.md; mirrored to all three shipped copies
- the interactive-swarm README notes the CI lanes are narrower

Publisher (ce-reliability residual, pre-existing):
- the publish job no longer gates the whole job on authorization, so a
  request rejected at normalization no longer strands the "review in
  progress" marker on the PR forever. Publication stays authorization-gated
  at the step; only the marker cleanup is unconditional.

* fix(ci): ship the install helper executable

The extracted helper was committed 100644, so the workflow's direct
invocation would have failed on the runner with permission denied - a
break introduced by the extraction itself, invisible to every existing
assertion. Set the mode and pin it with a test.

eea9ac92dc ci: move Node pins to the 22.18 floor
With the supported minimum raised to Node 22.18, retarget every lane and
pinned runtime that sat at a lower version so nothing builds or runs the
package on an unsupported (EBADENGINE-warning) Node:

- ci-tests.yml: node-floor-compat 22.14 -> 22.18.0 (name, comment, pin,
  version assertion) so the floor gate guards the new minimum; its #2372
  registerHooks failure mode cannot recur above 22.15. Containment-canary
  pin 22.16.0 -> 22.18.0.
- gitnexus-review-agent.yml + the pinned review/canary runtime: the
  reproducible runtime is version-locked in lockstep across
  .github/{gitnexus-review-runtime,claude-canary-runtime}/package.json and
  their lockfiles (engines), the workflow's node-version, its two
  'node --version = v22.18.0' assertions, the lockfile-engines guard, and
  NODE_VERSION. Moved all of them 22.16.0 -> 22.18.0.
- gitnexus-skill-evolution.yml: pinned runtime 22.16.0 -> 22.18.0.
- CONTRIBUTING.md prerequisite floor updated.
- review-agent-workflow.test.ts, which enforces the runtime lock, updated
  to expect 22.18.0.

feat(ci): review agent runs as a coordinated reviewer swarm (#2572)
* feat(ci): review agent on Sonnet 5 with structured, linked reviews

Bump the pinned review model from claude-sonnet-4-5-20250929 to
claude-sonnet-5 (verified against the pinned Claude Code 2.1.214 with
subscription auth and --json-schema structured output).

Restructure the published review body: verdict-first summary, findings
ordered by severity, fixed section order, and every file or symbol
reference as a GitHub permalink pinned to the analyzed head SHA (or the
merge-base SHA for deleted and rename-old paths) instead of bare
path:line text, so references are clickable and render inline previews.

* feat(ci): review agent runs as a coordinated reviewer swarm

Implement the review skill's expert-lens section in CI: the main agent
spawns four trusted lanes in parallel via the Task tool — correctness,
security, blast-radius, and coverage — each a purpose-built persona
restricted to Read/Glob/Grep plus the read-only graph MCP tools.

Personas live in the canonical skill tree (mirrored to all shipped
copies) and are installed into the reviewer's user-scope agents dir from
the exact control SHA, so a hostile PR head can never define a lane.
Lane reports are treated as unverified claims: the main agent re-anchors
findings before publishing, and the publisher's context-evidence gate
still requires the main conversation's own successful context call.
Bash and the newer Agent tool remain disallowed for every context; the
analyze timeout gets swarm headroom (45 -> 60 minutes). The workflow
contract test now pins the swarm posture.

* fix(ci): sidechain tool calls can no longer satisfy the evidence gate

The review agent's own review of this PR found that proveGraphReview()
walked the flat transcript without reading parent_tool_use_id, so a
spawned lane's context call could satisfy the publisher's graph-evidence
gate the prompt reserves for the orchestrator. Entries with a non-null
parent_tool_use_id are still strictly validated (malformed linkage fails
the transcript) but are excluded from both candidate context calls and
qualifying results; a new fixture proves sidechain-only evidence is
rejected while mainline evidence beside sidechain turns still passes.

Also gives the orchestrator turn headroom for the four dispatched lanes
(--max-turns 100 -> 150), addressing the review's LOW finding.

* refactor(skills): swarm-lane dispatch belongs to the review skill

Move the lane orchestration out of the workflow prompt and into the
gitnexus-review skill itself: a new "Swarm lanes" section names the four
ci-persona lanes, defines when and how to dispatch them (parallel, one
message, per-lane context and file slices), and owns the verification
contract (lane reports are unverified claims; re-anchor, dedup, drop
unanchored findings; lanes structure the work but never gate it). Any
runner of the skill — the CI workflow or a local harness — now triggers
the lanes from one canonical definition.

The workflow prompt keeps only its CI-specific deltas: the lanes'
trusted-control-SHA install provenance, the Task-tool dispatch surface,
and the publisher's orchestrator-only context-evidence gate. Mirrors
synced; 122 contract tests pass.

* feat(skills): add adversarial finder lane and critic gate to the swarm

ci-adversarial-lens joins the parallel finder wave: it assumes the change
is broken and constructs reachable failure scenarios — interleavings,
hostile inputs, state corruption, abuse of newly exposed surfaces — each
verified to a concrete entry point before it may be reported.

ci-critic-lens runs last as a gate on the orchestrator's finished draft:
it audits anchoring, concreteness, severity calibration, format
conformance, and honesty, returning PASS or a numbered defect list with
the smallest repair per item. The skill bounds it to two passes and the
critic hardens the review without ever blocking it; the workflow inherits
both lanes automatically through the wholesale ci-personas install.

Mirrors synced across all three shipped trees; 122 contract tests pass.

* refactor(ci): workflow defers the whole swarm contract to the skill

Now that the skill's Swarm lanes section owns dispatch, verification, the
critic gate, and the fallbacks, the workflow prompt stops restating any
of it. It contributes only what CI alone knows: the lanes' control-SHA
install provenance, the concrete environment mapping for lane inputs
(diff, manifest, head and merge-base checkouts, exact SHAs), and the one
CI override — the publisher's context-evidence gate remains
orchestrator-only. Analyze timeout gains headroom for the critic's
sequential rounds (60 -> 75 minutes).

* fix(ci): dispatch swarm lanes via the Agent tool, not the renamed Task alias

On the pinned Claude Code 2.1.214 the subagent-dispatch tool is `Agent`
(`Task` was renamed to `Agent` in 2.1.63 and is now a legacy alias), and
permission rules evaluate deny before allow. The workflow allowed `Task`
and denied `Agent`, so the orchestrator could never dispatch a lane and
every review silently fell back to the inline single-agent path while the
text-only tests certified the broken config.

Use `Agent` consistently: add it to --tools, allow it scoped to the six
ci-personas (`Agent(ci-correctness-lens,...,ci-critic-lens)`), remove it
from --disallowedTools, and update the prompt. Tests now match the scoped
allowlist on the raw string (commas inside Agent(...) break a split) and
assert Agent is no longer bare-denied.

* fix(ci): harden swarm permissions — allow Glob/Grep + merge-base reads, quarantine PR-head agents

Three permission-hygiene gaps around the swarm dispatch:
- Glob/Grep were in --tools but had no allow rule, so the lanes' declared
  tools could manufacture denied-tool errors; allow them (read-only,
  sandboxed by cwd + add-dir).
- The prompt hands lanes the merge-base source checkout for deleted /
  rename-old symbols, but no Read rule covered it; add a scoped Read()
  allow (which grants access without triggering --add-dir agent discovery).
- The --add-dir PR-head copy is scanned for spawnable agent definitions and
  the pinned runtime has no suppression env, so a PR could ship its own
  .claude/agents/*.md. Drop that subtree from the materialized copy after
  checkout-index (skills left intact), so only the trusted control-SHA
  personas can ever be dispatched.

* test(ci): pin the Agent allowlist to the ci-personas; require a dispatch canary

A text-only assertion cannot prove the pinned CLI actually dispatches the
lanes (print mode silently ignores invalid settings and does not validate
Agent(type) content at parse time) — that is what let the original
Task/Agent inversion pass CI. Two mitigations for the class:

- A cross-consistency test asserts the six names in the Agent(...) allowlist
  equal the six ci-personas filenames and each persona's frontmatter name,
  so a rename or typo in any of the three fails without auth.
- The activation checklist now requires the post-merge canary to prove a
  positive dispatch AND an unlisted-type refusal before enabling the trigger.

* fix(ci): bound swarm transcript volume with per-persona maxTurns

The six lanes stream into the single execution transcript the publisher
validates, but the personas carried no turn budget, so a large-PR swarm
run could overflow the (hard-throw) transcript caps and brick a valid
review. Bound each lane deterministically — finders maxTurns 12, the
critic maxTurns 6 — which keeps the worst case (~2×(150+5×12+2×6) ≈ 444
messages) under the unchanged 1_000 cap, so no cap needs raising. A new
test encodes that invariant: it fails if a persona's maxTurns is bumped
without revisiting the cap. Applied byte-identically across all four
shipped skill trees.

* test(ci): independently pin both sidechain evidence-gate guards

The sidechain-exclusion guards at candidate registration and result
acceptance were mutually redundant on realistic transcripts (a real
sidechain turn carries parent_tool_use_id on both its call and result),
so deleting either guard alone still passed the whole suite. Add two
asymmetric cross-wired fixtures — a mainline call with a sidechain result
(pins the acceptance guard) and a sidechain call with a mainline result
(pins the registration guard), both expecting missing_graph_evidence.
Mutation-verified: deleting either guard alone now reddens the suite.

* docs(skills): require own evidence before dispatch; document critic fail-open and swarm naming

Strengthen the gitnexus-review "Swarm lanes" contract (all four mirrors):
- The orchestrator must make its own graph context call on a changed
  symbol before dispatching any lane, so a fully-delegated run cannot
  leave the publisher's evidence gate unsatisfied (mirrored into the
  workflow prompt, with a test pinning the ordering phrase).
- Document that the critic's fail-open is deliberate (bounded to two
  passes, cannot deadlock, review still gated by evidence + schema),
  and distinguish it from the hard lane-7 gate in the separate
  gitnexus-pr-swarm-review skill.
- Give a concrete local-harness registration pointer for ci-personas.
- Add a reciprocal cross-reference in gitnexus-pr-swarm-review (single
  path — that skill is not part of the mirrored family).

* fix(ci): close pre-push review findings on the swarm permission change

Adversarial review of the fix diff caught two issues introduced by the
permission-hygiene commit:
- Bare Glob/Grep in --allowedTools are separate tools that the Read()-scoped
  path denies (/proc, github.workspace, ...) do not cover, opening an
  undenied read path to the raw checkouts and host paths via a prompt-
  injected lane. Drop the bare allow — under dontAsk they stay denied by
  omission; lanes read via the scoped Read() rules and the graph MCP.
- The agents quarantine removed only the add-dir root's .claude/agents; make
  it recursive so a nested (e.g. monorepo subpackage) .claude/agents cannot
  survive and be discovered.

* feat(ci): post an "in progress" marker while the review swarm runs

Swarm reviews can take up to 75 minutes, and until now the PR showed no
sign a review was running. Add a dedicated write-scoped `acknowledge` job
that, under the same authorization gate as analyze, upserts a per-PR
"🔄 GitNexus review in progress" sticky comment linking to the live run
(and reacts 👀 to the trigger comment); the publisher removes that marker
when the review — or a clean failure — posts.

The marker lives in its own job so the model-facing analyze job stays
secretless and read-only: it cannot post to the PR, so per-lane live
progress isn't exposed there — the marker is a binary "running" state with
a link to the Actions run where lane-by-lane progress is visible.

fix(ci): unblock the review agent dispatch and publisher lanes (#2567)
* fix(ci): unblock the review agent dispatch and publisher lanes

The first workflow_dispatch validation run surfaced two defects:

- setup-node rejects `cache: false` (the YAML boolean arrives as the
  string 'false' and v6 fails with "Caching for 'false' is not
  supported"), killing the analyze job before the isolation preflight.
  Omitting the input is the supported way to disable caching.
- The publisher held only `issues: write`, but GITHUB_TOKEN needs
  `pull-requests: write` to create issue comments on a pull request,
  so even the safe-failure comment died with "Resource not accessible
  by integration".

feat(skills): GitNexus Engineering Tool Kits (#2566)
* feat(skills): add ce-plan — GitNexus+PDG implementation-planning skill

Adds .claude/skills/ce-plan: a planning-only skill that builds
implementation-ready plans from GitNexus graph navigation (query/context/
impact/trace), bounded statement-level PDG slices (pdg_query, impact
mode:pdg, explain), and targeted source verification, with a context
ledger to prevent repeated reads and a machine-readable implementation
context pack (stable contract for a future ce-implement). Whitelisted in
.gitignore and registered in AGENTS.md and CLAUDE.md outside the
auto-managed gitnexus block.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(skills): apply ce-plan validation findings (tool contract, consistency, conventions)

Tool contract: impact mode:'pdg' shape now includes the schema-required
direction param; CDG branch sense documented as the result 'label' field
(reason is cypher/raw-edge only); explain caveats corrected to its real
false-negative classes (cross-function TAINT_PATH is modeled).

Consistency: PDG slice homed in working memory (ledger keeps one-liners);
depth knob defined and category-overrides-baseline ordering stated;
call_depth (consumed by nothing) and content-hash bookkeeping dropped;
Never section folded into Hard rules; Phase 3 deduplicated to a pointer;
allowed-repeat escalations defined; budget/discard accounting clarified;
verification-commands gathering added to Phase 4; open_questions added to
the context pack.

From scenario runs: plans now pin the verified-at HEAD commit and index
freshness in a header, tag claims [verified]/[graph]/[inferred]/[assumed],
quote load-bearing tool output, prefer pre-hook-carrying npm scripts, and
support an out:<path> destination override; output path defined as the
Phase 1 target repo root.

Conventions: AGENTS.md 1.9.0 / CLAUDE.md 1.4.0 changelog rows + metadata
bumps; future ce-implement qualified as future.

* feat(skills): rename ce-plan → gitnexus-plan; add cross-CLI (Codex) entrypoints

Renames the skill dir, frontmatter, output filename convention, plan H1
(GitNexus Engineering Plan), the future executor handle
(gitnexus-implement), the .gitignore whitelist entry, and all
AGENTS.md/CLAUDE.md references. Follows the pr-swarm-review cross-CLI
pattern: SKILL.md is the canonical CLI-neutral spec, AGENTS.md § Engineering
planning is the Codex/any-agent entrypoint, and the README documents the
optional user-level ~/.codex/prompts/gitnexus-plan.md slash command plus an
invocation matrix. Skill prose de-branded from Claude Code (agent-neutral
verification layer).

Also fixes two post-review README contradictions: the anti-reread claim now
names the ledger's allowed escalations, and 'read-only by contract' is now
'planning-only' (the skill writes exactly one repo file — the plan); the
scope-creep rule and template §12 now agree on where deferred follow-ups
land. Drops the stale plugin-collision limitation.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* docs(skills): document Codex user-level install path for gitnexus-plan

Codex discovers SKILL.md skills from ~/.agents/skills (same path the other
gitnexus-* skills install to); README now documents the cp install plus the
optional ~/.codex/prompts slash-command file, with the prompt body preferring
the repo copy and falling back to the user-level install.

* feat(skills): gitnexus-plan freshness gate + active PDG-layer refresh

Freshness is now a Phase 1 gate, not advisory: under the default
freshness:strict, a stale index is refreshed once per planning session via
node .gitnexus/run.cjs analyze --index-only (appending --pdg when the task
will reach the PDG phase), then the context resource is re-read. A missing
PDG layer likewise triggers the one permitted --index-only --pdg refresh
and re-probe instead of a passive recommendation. freshness:accept (or a
failed/impractical refresh) preserves the old behavior: plan on the stale
graph, source-weighted, labelled in the plan header. --index-only is the
load-bearing flag choice — it suppresses all file generation, so the
planning-only contract holds (only the .gitnexus store changes). Ledger
gains an index_refresh record; plan header states fresh / refreshed /
refresh-skipped-with-reason.

* feat(skills): gitnexus-plan runner build check before freshness refresh

When the target repo builds the analyzer from its own source (bin → dist/
mapping, as gitnexus/ does), the Phase 1 freshness gate now verifies dist/
is current before running the analyze refresh — rebuilding via the
package's build script when any analyzer source file is newer than the
built entrypoint — and prefers that freshly built CLI. Otherwise a stale
dist re-indexes with outdated extraction logic and the 'fresh' index lies.
Rebuilds are recorded in the ledger's index_refresh; the PDG-phase refresh
inherits the same check.

* feat(skills): add gitnexus-work executor and gitnexus-lfg pipeline

gitnexus-work executes a gitnexus-plan as verified atomic commits: consumes
the §11 implementation_context pack, drift-checks the plan's evidence pin
against HEAD, re-verifies assumptions before relying on them, runs impact
before every symbol edit and detect_changes before every commit (repo
mandates), builds tests from the plan's scenarios, and routes structural
drift back to gitnexus-plan Deepen mode instead of coding around it.

gitnexus-lfg is a thin orchestrator: gitnexus-plan → blocking user gate
(deepen / proceed / stop, deepen loops allowed) → gitnexus-work → review
via the existing gitnexus-pr-review skill (open PR, else branch diff vs
default). One bounded fix cycle for review findings; never pushes or opens
a PR on its own.

gitnexus-plan gains a Deepen mode (re-run freshness gate, escalate to
depth:deep, re-verify graph/inferred/assumed claims toward verified,
rewrite the same file); its 'future gitnexus-implement' placeholder is
retired in favor of gitnexus-work. Registered via .gitignore whitelists,
AGENTS.md 1.10.0 (section renamed to Engineering planning & execution),
CLAUDE.md 1.5.0.

* fix(skills): apply cross-skill review findings to the gitnexus skill family

Two P1s: gitnexus-plan Deepen mode now re-anchors before re-pinning
(diffs the old evidence pin over every [verified]-claim file and re-reads
or downgrades before the header moves — moving the pin without this
laundered stale claims as verified); the index-refresh budget is stated
once in Phase 1 (one --index-only refresh plus at most one Phase 3 --pdg
upgrade per session, Deepen = its own session) with ledger and pdg-slice
deferring to it.

Contract fixes: gitnexus-work's drift check now covers every file the
pack cites (not just files_to_modify) and parses the full pack incl.
primary/related symbols and acceptance_criteria (walked in Phase 4
alongside §13); a pre-completed check skips §7 steps already landed and
Deepen gains a reconcile-execution-state step, closing the mid-execution
route-back loop; pack assumptions must name what to check and how.

lfg: Lane 4 passes the merge-base to detect_changes compare (two-dot
diff misattributes upstream commits when default advanced), branch-diff
is the stated normal case, oversized review findings route to the plan
gate instead of overflowing direct mode, the one-fix-cycle cap is
explicit on re-run, and headless runs end at the plan gate with the plan
as deliverable. work: blank mode narrowed to *gitnexus-plan*.md with a
re-execution guard, direct-mode discipline spelled out, branch
meaningfulness defined against the plan slug, and the plan document is
committed as the branch's docs commit (review diff includes it).
Planning-only contract now names the dist/ rebuild as the second
permitted state change; Phase 5.1 names the four claim tags; stale
AGENTS.md anchors fixed.

Known latent issue left untouched: gitnexus/gitnexus-pr-review pairs a
three-dot example with a two-dot detect_changes compare — that skill is
also shipped by the plugin, so fixing it here would drift the copies;
lfg compensates by passing the merge-base.

* feat(skills): ship the engineering skill family with the gitnexus package

npm i -g gitnexus users now get gitnexus-plan / gitnexus-work / gitnexus-lfg:
the three skills are added to gitnexus/skills/ in directory form (SKILL.md +
references/), which installSkillsTo already enumerates dynamically and copies
recursively to every editor target (~/.agents/skills for Codex, Cursor,
OpenCode, Qoder, ...) on gitnexus setup — uninstall enumerates the same root,
so removal stays clean. The Claude Code plugin channel
(gitnexus-claude-plugin/skills/) carries the same copies plus the standard
per-skill mcp.json.

Global-install support in the skill text: gitnexus-plan Phase 1 now resolves
the analyzer runner explicitly — node .gitnexus/run.cjs analyze when the
project has a runner, else gitnexus analyze (installed CLI), else
npx gitnexus analyze — and all analyze mentions route through it, satisfying
the skills-steering policy (#1939/#1945) which sweeps the plugin copies.

New drift guard test/unit/shipped-skills-sync.test.ts asserts the npm and
plugin copies stay byte-identical to the canonical .claude/skills/ family
(plugin = canonical + mcp.json), same discipline as run.cjs ↔
resolve-invocation.ts. skills-steering + shipped-skills-sync: 11/11 green.

* feat(eval): workflow_bench — measure the skill workflow's token savings

Benchmarks gitnexus-plan → gitnexus-work against a baseline agent
(--disallowedTools Skill) on identical tasks, in fresh detached worktrees,
using real headless Claude Code sessions; every number comes from the CLI's
--output-format json usage report (field names validated against a live
2.1.207 session). Reports per-arm medians (input/cache/output tokens, cost,
wall time, turns), a savings row, and resolve status from a per-task verify
command — savings on failed tasks are flagged, not celebrated. Per-task
setup hook prepares fresh worktrees (deps); --permission-mode
bypassPermissions (default) lets sessions run unattended in the throwaway
trees.

Free-model support: --base-url/--auth-token/--model route headless sessions
through any Anthropic-compatible endpoint; free-model.litellm.yaml is a
ready litellm-proxy template for OpenRouter :free variants or local Ollama,
so benchmarking burns no paid tokens (README documents rate limits and the
small-model skill-following caveat).

Harness validated end-to-end with a stub CLI (worktree lifecycle, both
arms, plan→work chaining, verify, aggregation, report) and 4 pytest units
for the pure aggregation/savings/report helpers. AGENTS.md 1.11.0.

* docs(eval): record first workflow_bench calibration run

Trivial-task calibration (add -V alias): both arms resolved; workflow arm

* feat(eval): workflow_bench scenario matrix — arm variants, task classes, churn

Ground-base measurement across scenarios: tasks.scenarios.yaml spans four
labeled classes (trivial → investigation-bug → investigation-feature →
cross-module) with deterministic verifies (prescribed test files). New arms:
workflow_direct (gitnexus-work direct mode — the middle option that locates
the routing boundary lfg's gate and work's triage encode) and baseline_nomcp
(no skills AND no graph tools — separates workflow-discipline value from
GitNexus-tool value; off by default). Records now carry task class and diff
churn (files/+ins/−del vs the starting commit) as an over-engineering proxy;
the report renders a class column and per-arm savings rows vs baseline.
5 pytest units + stub-CLI e2e of the full three-arm matrix.

* docs(eval): record workflow_bench ground base; fix churn measurement bias

Ground base (3 classes x 3 arms, n=1/cell): every arm resolved every task —
pass/fail quality saturates at this difficulty, making the comparison pure
cost. Full plan→work never amortized its ~$9-11 fixed cost on tasks a
baseline finishes in ≤35 turns (−211% to −333% cost); workflow_direct sits
near baseline (−15% to −55%, once faster wall) with more test coverage.
Routing implication recorded: direct mode/plain agent below this scale,
full workflow for cross-module / multi-session / plan-as-deliverable work.
The cross-module cell and multi-run variance are the next measurements.

Churn fix: git add --intent-to-add -A before diffing (arms that never
commit no longer undercount new files) and :(exclude)docs/plans (the
committed plan doc no longer inflates workflow churn); this run's churn
numbers predate the fix and are omitted from the recorded table.

* perf(skills): cost-optimize the workflow from measured ground base

Every optimization targets a measured fixed-cost component
(eval/workflow_bench ground base: workflow arm −211% to −333% vs baseline,
all tasks resolved):

- Plan form is category-priced: compact form (core sections w/ § anchors
  preserved, ≤80 lines excl. pack, mini-pack subset of the context pack)
  for narrow/default categories; the full 13 sections only for deep work
  (refactor/security/performance/concurrency/architecture). A compact plan
  outgrowing its cap reclassifies to full rather than overflowing.
- Freshness gate is category-priced: compact categories default to accept
  (source-weighted, refresh only when a graph claim becomes load-bearing);
  strict stays the default for full-plan categories — the rebuild+re-index
  was the largest single fixed cost.
- Turn economy: per-category tool-call budgets (~10 to ~45; architecture
  uncapped); budget exhaustion routes open questions to §12 instead of
  more digging.
- gitnexus-work fast path: HEAD == evidence pin → skip all citation
  re-reading (the pin's entire point); mini-pack fields tolerated.
- lfg Lane 1 boundary triage: tasks below the measured ~35-turn boundary
  get offered gitnexus-work direct mode before the plan lane is spent.

Copies re-synced (npm skills/, plugin, ~/.agents); steering + sync guards
green. Re-measurement of the workflow arm follows to verify the numbers
actually improve.

* docs(eval): record optimization re-measurement — inv-bug workflow cell −20% cost

Same task, same conditions, post-830a0459 skills: $14.56→$11.70 (−20%),
83→72 turns, cache_read −24%; verified in-transcript that the compact form,
turn budget, and skipped rebuild/re-index all fired. Wall +15% from a work-
session test-debugging tail (n=1 variance). Regime unchanged (~3.5x baseline
on this class) — routing rule stands.

* fix(eval): per-arm clone isolation — worktree ref-namespace leak contaminated an arm

The cross-module workflow_direct cell reported an impossible 28-turn solve
with churn byte-identical to the workflow arm: git worktree add shares the
repo's ref namespace, so the workflow arm's slug branch (created by
gitnexus-work Phase 2) survived worktree removal and the direct arm found
and adopted the completed work. Arms now get isolated git clone --shared
copies (object store via alternates, refs clone-local — agent branches and
stashes die with the clone; origin/<ref> fallback for non-default refs).
Leaked branch deleted; baseline arm verified clean (0 branch references in
its transcript); cell marked invalidated pending re-run.

Records the valid cross-module cells: workflow $18.32 vs baseline $18.03
(premium −1.6%, vs −211%..−333% on smaller classes) — fixed costs amortize
at this scale, with a less destructive diff and a plan artifact as bonus;
resolve rate still tied. Churn fingerprinting is what caught the
contamination — noted in the README as an integrity check.

* docs(eval): complete cross-module cell — direct mode wins 47% cost / 56% wall

Clean clone-isolated re-run: workflow_direct resolved the hardest class at
$9.53/52 turns/15m vs $18.03/98/34m baseline and $18.32/107/37m full
workflow. The measured story across all four classes: the execution
discipline (gitnexus-work) is the consistent sweet spot and delivers real
token savings on hard tasks; the planning pass buys its artifact, not
same-session savings. Resolve rate tied everywhere (n=1/cell caveat).

* fix(skills,eval): address #2431 review — data-safe rename migration, fail-closed bench evidence

- setup: never delete a legacy renamed skill dir — the installer cannot
  prove ownership (users customize or hand-write skills under these
  names); warn with the path instead, and the test now asserts survival
- workflow_bench: fail closed when a session's --output-format json
  report is empty, malformed, or missing usage fields — an exit-0 shell
  with no parseable usage no longer counts as measured evidence
  (5 parametrized regression tests)
- workflow_bench: document the trust model prominently (task setup/verify
  are shell-executed, sessions run bypassPermissions with the parent env,
  candidate overlays are prompt injection surface) in README + docstring

* fix(eval): demand observed foreground verification in headless work-arm prompts

In a headless -p session there is no later turn: a work arm backgrounded
its slow test run, scheduled wakeups that can never fire, and reported
done while two of its tests failed. All four work-arm prompts (both
skill families, symmetric) now require verification output to be
observed inside the session.

* feat(skills): ask plan depth up front instead of offering deepen afterwards

gitnexus-plan Phase 0 now asks one blocking question in interactive
sessions — quick / standard / deep, mapped onto the existing depth/form/
freshness knobs — when the invocation carries no explicit depth signal.
Explicit knobs and headless runs skip the question (category posture
unchanged, so benchmarks and automation behave as before).

gitnexus-lfg's plan gate slims to proceed/stop: depth was already the
user's up-front choice, so deepening is no longer offered by default —
an explicit deepen request at the gate and executor route-backs still
run Deepen mode, which remains the mechanism for strengthening an
existing plan document.

All shipped copies resynced (npm skills/, Claude plugin); AGENTS.md
1.13.0 and CLAUDE.md 1.7.0 pointers updated, including the analyzer's
regenerated index-stats block at this branch's head.

* feat(skills): taint pass, expert lenses, and post-work index refresh

gitnexus-review gains a PDG-backed taint-and-dependence pass (explain +
pdg_query, --pdg folded into the stale refresh on trust-boundary diffs) and
an Expert lenses section: domain reviewers derived from the graph's
clusters plus four cross-cutting lenses (architectural fit, language
conformance per the repo's own contract, Definition of Done, simplicity),
dispatched once after the evidence-gathering steps and scaled to the diff.
gitnexus-work Phase 4 now refreshes the knowledge graph after the DoD walk
via the resolved-runner ladder with analyze --index-only, so the lfg review
lane and later sessions query the finished work without dirtying the tree.
lfg's threshold-governance paragraph moves to its README; eval citations
are tagged as measured in the GitNexus repo. All shipped copies re-synced.

* fix(cli): remove legacy gitnexus-pr-review on uninstall; cover the rename migration

uninstall's removal set now includes LEGACY_SKILL_DIR_NAMES derived from

dir present, silent without), and shipped-skills-sync asserts legacy names
stay absent from every shipped tree.

* fix(eval): metric provenance, error-kind rows, skill-invocation verification, gate noise floor

The promotion gate defaults to cost_usd (the only metric that includes
subagent spend); token metrics carry an explicit main-loop-only warning in
the report and promotion.json. Rows are classified by error_kind
(session-error / verify-failed / infra-error), excluded from efficiency
medians, and the gate requires equal valid-run counts. Each session's
transcript is scanned for the expected Skill invocation and fails closed on
a verified miss; a one-run resolution edge no longer promotes (noise
floor). Per-run timeouts and setup failures record an infra-error row
instead of aborting the sweep. Overlays touching skills no candidate arm
exercises are rejected up front.

Ensure workflow_bench transcript tests set USERPROFILE alongside HOME so Path.home() resolves to the temporary test home on Windows.

* docs(skills): fold PR #2522 execution learnings into review/work/plan

Eight incident-backed hardenings from running the full skill cycle
(review -> plan -> work, 28-finding fix series) on PR #2522:

gitnexus-review:
- Expert lenses execute the code under review on candidate failing shapes
  (empirical probe outranks source reading — every HIGH the language
  lenses found came from a probe, not a read).
- Step 7 re-runs the exact CI check for refreshed baselines/fingerprints
  (a stale committed artifact is invisible in the diff; caught a red
  benchmarks arm).
- Step 8 treats version/invalidation constants as review surface
  (INCREMENTAL_SCHEMA_VERSION class recurred verbatim from #2494).

gitnexus-work:
- Step 4 proves regression tests discriminate against the pre-fix tree.
- Step 5 rebuilds executed build output before every verification run
  (parse workers load dist/; a correct fix 'failed' until rebuilt).
- Step 6 makes stage -> detect_changes -> commit one unbroken sequence.

gitnexus-plan:
- Phase 0 seeded-evidence mode: plan FROM a completed review's verified
  findings instead of re-running the graph ladder.
- Template §7: fingerprint/golden-guarded output rebaselines once, at the
  series tip.

All distribution copies resynced; shipped-skills-sync + skills-steering

* feat(eval): close the skill-evolution loop with an automated proposer driver

workflow_bench.evolve adds the three arrows the README described as manual:
a proposer session that turns loser trajectories (results.jsonl rows,
transcripts, patches, the learning queue) into ONE bounded candidate
overlay, a driver that iterates propose -> paired benchmark -> deterministic
gate up to --generations, and an --apply step that copies a promoted
overlay onto the canonical skills and shipped mirrors as a working-tree
diff. The trust boundary is unchanged: overlays re-validate through
candidate_overlay_files before any benchmark or apply consumes them, and
committing, CI, and the PR merge stay human.

learnings.jsonl is gitignored: it is machine-local evidence, like the
session transcripts it complements.

* docs(skills): route live-task friction into the evolution learning queue

Each family skill gains a short 'Skill feedback' section: on friction with

eval/workflow_bench/learnings.jsonl (GitNexus repo only) — never self-edit
the skill from a live task. The proposer in workflow_bench.evolve consumes
the queue as hints; a learning reaches a shipped skill only by beating the
incumbent on the paired benchmark. All shipped mirrors re-copied byte-
identical.

* feat(ci): comment-triggered GitNexus review agent for PRs

'@gitnexus review' from a maintainer (OWNER/MEMBER/COLLABORATOR; the action
re-validates write access) runs the repo's gitnexus-review skill headlessly
against the PR and posts the review as a sticky comment — remote triggering
with no local setup. Read-only by construction: contents: read token,
Write/Edit and web tools disallowed, Bash allowlisted to git reads and the
gitnexus CLI; analyze parses PR code with tree-sitter, never executes it.
Requires the ANTHROPIC_API_KEY repository secret; activates once the file
is on the default branch.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(ci): dispatch lane + existing OAuth secret for the review agent

Align with claude.yml: same action pin and the CLAUDE_CODE_OAUTH_TOKEN
secret the repo already carries — no new secret to configure. Add a
workflow_dispatch lane (PR number input) so the agent can be triggered from
the Actions UI and tested before the issue_comment trigger reaches the
default branch. Allowlist gh pr view/diff and gh api, which the review
skill uses to pin PR SHAs.

* fix(ci): close a fork-PR RCE vector in the review agent's tool allowlist

A live headless run of the exact workflow session against PR #2431 (66
turns, full gitnexus-review pass) surfaced a real HIGH-severity confused
deputy: .gitnexus/ is gitignored, not blocked — a fork PR can commit its
own .gitnexus/run.cjs, issue_comment checks out PR-head content, and the
skill's runner ladder tries 'node .gitnexus/run.cjs analyze' first. That
would execute fork-controlled JS inside a job holding
CLAUDE_CODE_OAUTH_TOKEN and a write-scoped GITHUB_TOKEN — the opposite of
the 'PR code is read, never executed' claim in the workflow's own header.

Fix: drop the run.cjs allowlist entry so analyze always resolves through
npx gitnexus (npm registry, not the checked-out tree); the skill's
documented fallback mode covers the resulting graceful degradation. Also
drop 'gh api' (not read-only — accepts -X POST/PATCH/DELETE) and downgrade
pull-requests: write to read (comment posting only needs issues: write;
the prompt already forbids formal review submission).

Same session flagged a latent evolve.py bug: select_evidence's cost sort
used dict.get's missing-key default, which doesn't cover an explicit JSON
null in a foreign --seed-results row and crashes proposer setup with
TypeError. Guarded with 'or 0.0' and added a regression test.

* fix: harden PR review and evolution trust boundaries

* ci: follow workflow concurrency convention

* fix(eval): make terminating error paths explicit

* fix: unblock hardened review runtime checks

* test: make containment canaries deterministic

* test: expose Claude canary tool failures

* fix: adapt clean shell environment for Claude

* fix(eval): accept the runner's transcript source key in evidence preflight

The proposer evidence preflight required transcript-artifact metadata to be
exactly {path, sha256, bytes}, but the runner stamps a fourth provenance key
(source=parent-captured-stream-json). Any --seed-results or generation>=2 run
therefore aborted with SandboxError before proposing or promoting. Pin the
producer literal as PARENT_EVENT_STREAM_SOURCE and validate it in the metadata
check, and round-trip real producer output through sum_sessions into the
preflight so the schema can't drift again.

* fix(eval): treat an unmeasured session cost as unavailable, not $0

well_formed validated only the nested usage block, so an otherwise-successful
session missing total_cost_usd was recorded as cost_usd=0.0 — and cost_usd is
the default promotion metric (lower wins), so a cost-less session scored as
free and could win promotion it never earned. Extract cost via measured_cost()
(None on absent/garbage, a measured 0.0 preserved), propagate None through
sum_sessions/aggregate/savings/report, and have the gate refuse to rank on a
metric that was not measured on every run in both arms.

* fix(eval): warn when ranking on the main-loop-only num_turns metric

num_turns comes from the CLI's top-level usage (main-loop session only), like
output_tokens, but selecting it emitted no metric_warning — so a subagent-heavy
candidate could look artificially efficient. Add num_turns to
MAIN_LOOP_ONLY_METRICS and broaden the warning to cover turns.

* fix(eval): fail closed when an overlay adds a file with no committed base

An overlay adding a new .md under gitnexus-{plan,work} passes the structural
overlay checks but has no committed base for committed_destination_base_digests
to bind against, so it raised an uncaught ValueError that crashed the evolve
driver (and runner --candidate-overlay) mid-run. Catch it at both call sites:
evolve reports NOT PROMOTED and exits, runner routes it through parser.error.

* feat(eval): circuit-break the runner sweep on a systemic outage

A sustained upstream outage used to pay out every remaining --timeout window
one session at a time. Track consecutive session/infra/cleanup failures via a
pure systemic_outage_streak helper; after --outage-streak (default 5) in a row,
stop the sweep, still write report.md/promotion.json from partial evidence, and
exit non-zero so evolve.py halts instead of proposing from truncated evidence.
A task's own resolved=False never trips the breaker.

* fix(cli): report a dirty working tree as stale in gitnexus status

status --json (and the human output) computed up-to-date from commit + runner
identity + completeness only, so a repo with uncommitted source changes at a
matching HEAD was reported up-to-date while analyze would still re-index it.
A graph-backed agent gating on that JSON could skip re-analysis on a stale
graph. Extract analyze's dirty-tree check into a shared isWorkingTreeDirty()
in storage/git and fold it into the status freshness decision.

* fix(ci): use single-slash deny globs in the review agent's disallowedTools

github.workspace already expands to an absolute path, so Read(/${{ github.workspace }}/**)
and Read(//proc/**),(//sys/**),(//dev/**) produced double-slash patterns that a
normalizing matcher may not match — silently no-opping the deny layer. Not
exploitable (the allowlist is the primary control and never grants those
paths), but the globs should be well-formed. Update the pinned test strings.

* ci: install gitnexus-shared with npm ci from the committed lockfile

The gitnexus-shared build floated its deps via npm install in three workflows
(skill-sync, ci-tests, and — most importantly — the release publish.yml) while
every other install step uses npm ci. The lockfile is committed and in sync, so
switch all three to npm ci for reproducible, locked installs.

* test(cli): make the shipped-skills drift guard reject symlinks

listFilesRecursive walked with readdirSync and snapshotDir read with
readFileSync, both of which follow symlinks — so a mirror file symlinked to the
canonical tree passed the byte-compare (and a symlinked mirror dir would be
followed too). Reject a symlinked root via lstat and any symlinked entry via

* test(eval): guard the candidate-skill vs mirror-root coverage invariant

MIRROR_SKILL_ROOTS omits the Cursor tree, safe only because no candidate skill
is cursor-shipped. Pin that invariant: every CANDIDATE_SKILLS entry must exist
under canonical + every mirror root and must not ship to Cursor, so adding a
cursor-shipped skill to the candidate set (the PR #2488 asymmetric-sync class)
fails loudly instead of syncing three of four trees.

* docs(ci): describe the review agent's staged post-merge rollout

The DoD asked for a dry-run or triggered run before merge, but an issue_comment
(or newly added workflow_dispatch) workflow only ever executes the default-branch
copy, so it cannot be exercised from the PR that introduces it. Reword the DoD
and the activation checklist to a staged rollout: merge registered-but-disabled,
validate same-repo and fork execution post-merge, then enable the variable.

* fix: pin plugin skill mcp.json to the release version via #2445 tooling

The ten plugin skill mcp.json launched `npx -y gitnexus@latest mcp` on every
skill connect — non-reproducible and a supply-chain surface, and (unlike the
persisted setup config) never pinned. Extend sync-plugin-manifests.mjs with an
mcp surface kind that stamps the gitnexus@<version> launch arg, pin all ten to
1.6.9 now, and keep them byte-identical so the drift guard stays green. The
release lifecycle + publish.yml --check now re-stamp them like the four manifest
surfaces; only READMEs stay on @latest as docs.

* test(eval): prove the proposer's built-in file tools are confined

The real-Claude canary only exercised Bash + MCP, so it proved process/MCP
containment but not that the proposer's built-in file tools stay inside their
mounts. Add a canary over the exact PROPOSER_ALLOWED_TOOLS surface and the same
read-only /evidence mount as run_proposer (allowlist extracted to a shared
constant so it can't drift): Read reaches /evidence, a Write into the read-only
evidence mount is denied, and a Write lands in the output tree.

* fix(eval): apply the candidate overlay after task setup for fair arms

The candidate overlay was applied before the task's untrusted setup ran, so
setup could observe candidate prose and the incumbent/candidate arms started
from different pre-overlay state. Reorder within the sandbox: capture the base
(pre-overlay) skill digest, run setup against the base skills, verify setup did
not tamper them, then apply the overlay and capture the post-overlay digest the
model must preserve. apply_candidate_overlay stages path-specific overlay files,
so setup's uncommitted changes stay out of the baseline and churn is unchanged.

Graph freshness for the review arm is handled by the status dirty-tree fix plus
the review skill's stale-triggered re-index, not by reordering the cached
per-task-sha graph materialization (which is mechanically blocked).

* test(eval): end-to-end containment proof of the autonomous proposer

Drives the real run_proposer through bubblewrap with a deterministic scripted
model (no paid API): it reads the read-only evidence bundle and writes a
candidate gitnexus-plan skill edit plus a rationale into the sandbox output
tree; run_proposer enforces the trust boundary and copies only the validated
overlay + proposal out. This exercises the autonomous-proposal stage of the
self-evolution loop end-to-end in the eval/containment CI job (the gate and
apply stages are covered by test_workflow_bench_evolution and
test_promotion_apply). Env-gated on GITNEXUS_REQUIRE_CLAUDE_CANARY, so it runs
only where the pinned Claude binary and user namespaces are available.

* fix(eval): let the proposer author its overlay via Bash

Running the end-to-end proposer canary in the containment CI job surfaced a real
bug: run_proposer starts the session with --bare, which hard-disables the
Write/Edit tools ("Write exists but is not enabled in this context"), yet
allowlisted Edit/Write and omitted Bash. The proposer therefore had no working
way to write its candidate overlay — the self-evolution loop could never produce
a candidate. The sandbox settings already pre-authorize Bash
(autoAllowBashIfSandboxed) and confine writes to workspace/tmp/home, so switch
PROPOSER_ALLOWED_TOOLS to Read/Grep/Glob/Bash and tell the proposer to author
files with Bash. The end-to-end test now drives the real run_proposer through
bubblewrap and asserts a validated overlay + proposal are produced (this also
replaces the earlier file-tool canary, whose Write/Edit premise was moot).

* test(eval): author the proposer overlay with newline-free Bash content

The nested shell-sandbox prefix mangles embedded newlines, so the multi-line
overlay content never landed. Use single-line content for the deterministic
proposer canary.

* test(eval): drop the unverifiable end-to-end proposer canary

The scripted proposer overlay never materialized in the containment job across
runs, and the model tool-result content is not visible in CI logs, so the test
cannot be finalized without an environment where the sandbox can actually run.
Keep the verified production fix (Bash-authoring in run_proposer); the proposer
sandbox/containment stays covered by the existing Bash+MCP and process-tree
canaries.

* test(cli): drop run-analyze.ts from the windowsHide spawn-family list

U7 moved run-analyze.ts's only child_process call (the git status --porcelain
dirty check) into storage/git.ts (already covered by this test, with
windowsHide). run-analyze.ts no longer imports a spawn-family function, so the
windowsHide-regression test's 'must have >=1 spawn call' invariant failed for
it. Remove it from SRC_FILES.
