18c899def5 enhance(#4209): optional external source reviewer lanes for /gsd:code-review (#4323)
* test(01-01): define reviewer-support trait contract

Add failing coverage for step.supportsReviewerLanes (#4209 DISP-02):
validator rejects non-boolean values with an exact field path, accepts
missing/true/false, and the real code-review capability.json steps
must declare supportsReviewerLanes: true. Add loop-resolver projection
coverage proving the trait reaches activeHooks verbatim for a
provider-neutral synthetic step (not code-review-specific), and that
omitted/false values stay inert (no key on the active hook).

All 8 new assertions fail today: the validator has no such field, and
loop-resolver has nothing to project. RED before GREEN.

* feat(01-01): declare reviewer-capable steps

Add step.supportsReviewerLanes (#4209 DISP-02): a strict optional
boolean opt-in trait, step-scoped (not capability-wide). Only a
literal true validates and projects; false/omitted stay inert (no
key on the projected active hook), and every non-boolean type fails
capability-validator.cjs with an exact field-path error.

Opt both existing code-review steps (execute:post, execute:wave:post)
into the trait in capabilities/code-review/capability.json. Project
the validated field through src/loop-resolver.cts into activeHooks
so a provider-neutral generic interpreter can read it without any
code-review-specific knowledge. Document the field in
docs/reference/capability-manifest.md and regenerate
gsd-core/bin/lib/capability-registry.cjs via the generator (never
hand-edited).

Makes all 8 RED assertions from the prior commit pass.

* test(01-02): define shared reviewer dispatch

- Add tests/reviewer-step-dispatch.test.cjs covering dispatchReviewerLanes:
  inert when the supportsReviewerLanes trait is off or nothing is selected,
  exactly-once plan/invoke per selected lane, duplicate-alias dedup, the
  bounded metadata-only source-review prompt (repo root, paths+baseSha,
  depth, four fixed prohibitions), and capability-neutral reuse via a
  second synthetic step context.
- RED: module under test (src/reviewer-step-dispatch.cts) does not exist
  yet, so require() fails and every assertion is unreached.

* feat(01-02): dispatch reviewers for opted-in steps

- Add src/reviewer-step-dispatch.cts: dispatchReviewerLanes(input, deps),
  ONE interpreter for a step's supportsReviewerLanes trait. Reuses
  resolveReviewerSelection for selection and resolveLanePlan for planning
  (both already-existing, pure building blocks); invocation is the one
  required, caller-injected seam (deps.invoke) since runLane needs
  OS-aware spawn plumbing this module does not own.
- trait !== true, or a selection resolving to zero lanes, dispatches
  nothing (zero plan/invoke calls). Each selected lane is planned and
  invoked exactly once, in the selector's deduped/sorted order.
- buildSourceReviewPrompt assembles a metadata-only bounded prompt
  (repo root, canonical paths + base SHA, depth, four fixed
  prohibitions) — never file contents — written once per dispatch and
  shared across every invoked lane.
- GREEN: tests/reviewer-step-dispatch.test.cjs now passes.

* test(01-02): define reviewer dispatch failures

- Extend tests/reviewer-step-dispatch.test.cjs with the fail-closed
  matrix: an explicitly requested lane the selector could not resolve
  still lets the OTHER resolved lane run, but the aggregate result must
  never read as a clean success (and 'every explicit lane unavailable'
  must be distinguishable from the plain no-flags-passed inert case);
  request-level validation (path traversal, absolute paths outside
  repoRoot, empty/non-string paths, missing depth/base SHA) halts the
  whole dispatch before any lane is planned or invoked; a per-lane
  prompt-budget overflow hard-fails only that lane before invoke while
  its sibling still runs.
- RED: src/reviewer-step-dispatch.cts does not yet implement any of
  these guards, so 9 of the new assertions fail against the current
  (Task 1) implementation.

* fix(01-02): fail closed in reviewer dispatch

- src/reviewer-step-dispatch.cts: add the fail-closed guards the prior
  commit deliberately left out. An explicitly requested lane the
  selector could not resolve no longer lets the aggregate read as a
  clean success — lanes that DID resolve still run and keep their
  results (never narrow the requested set), but selection.errors now
  flips the aggregate ok to false, and 'every explicit lane
  unavailable' is now distinguishable (SELECTION_FAILED) from the
  plain no-flags-passed inert case (NO_LANES_SELECTED).
- Add request-level validation (validatePaths, depth/baseSha presence)
  that halts the WHOLE dispatch before any lane is planned or invoked:
  path traversal, absolute paths outside repoRoot, empty/non-string
  paths, and missing provenance are all rejected up front.
- Add per-lane prompt-budget enforcement (resolveBudget, mirroring
  gsd-tools.cjs's budgetFor convention including budget 0 = unbounded):
  a lane whose resolved budget the prompt exceeds hard-fails before
  invoke runs for it, without cancelling a sibling lane already
  planned.
- Document the supportsReviewerLanes trait and its dispatch-step
  interpreter in gsd-core/references/loop-hook-dispatch.md.
- GREEN: all 19 tests in tests/reviewer-step-dispatch.test.cjs pass;
  no regressions in the review-lane/reviewer-selection/prompt-budget
  suites (356 passing).

* test(01-03): define optional source reviewer flow

RED: assert code-review.md dispatches roster-derived reviewer-lane flags
through a single review-lane dispatch-step call (DISP-01..05), that the
no-flag path stays byte-for-behavior unchanged (COMP-01), and that
external evidence reaching the internal reviewer prompt is marked
unverified (CONS-02). Also covers the CLI contract directly: no-op with
no explicit selection, and fail-closed on an explicit unknown lane
(SAFE-07) via real gsd-tools.cjs subprocess calls.

* feat(01-03): route optional source reviewers

GREEN: code-review.md gains a dispatch_reviewer_lanes step that matches
canonical reviewer-lane flags against the merged first-party + installed
roster (never a hand-maintained list) and, only when at least one is
present, calls the shared reviewer-step interpreter exactly once with the
already-resolved repo root, file scope, depth, and base SHA. Its evidence
paths are appended to the internal reviewer prompt via
${EXTERNAL_EVIDENCE_BLOCK}, explicitly marked unverified. No reviewer-lane
flag leaves the internal-only dispatch byte-for-behavior unchanged
(COMP-01).

Deviation (Rule 3 — blocking issue): 01-02 documented `review-lane
dispatch-step` (gsd-core/references/loop-hook-dispatch.md) as the CLI
route `dispatchReviewerLanes` wires through, but never implemented the
gsd-tools.cjs subcommand — the workflow's call had nothing to reach. Add
it to the existing review-lane router, reusing the same effort-aware plan
building and runner deps `plan`/`invoke` already use (factored into
buildLaneRunnerDeps to avoid duplicating the spawn/http/fs seam). Guard
the CLI's own `detected` set on whether an explicit flag was passed:
resolveReviewerSelection's no-explicit-selection fallback is "select every
detected reviewer" (the correct default for /gsd:review), and passing it
an unconditionally non-empty detected set would silently invoke the whole
roster on every no-flag code review, violating COMP-01.

* test(01-03): define external finding consolidation

RED: assert gsd-code-reviewer.md treats <external_reviewer_evidence> as
untrusted input — independently re-verifies every claim against the actual
current source, resists a prompt-injection attempt embedded in evidence
text, and folds a verified claim into the existing Narrative Findings
section with no second REVIEW.md schema (CONS-01..03). Also assert
code-review.md's EXTERNAL_EVIDENCE_BLOCK restates the four fixed
source-review prohibitions (SAFE-03..06) at the internal-reviewer handoff.

* feat(01-03): consolidate external review evidence

GREEN: gsd-code-reviewer.md's load_context parses <external_reviewer_evidence>
as untrusted data, independently re-verifies every cited claim against the
actual current source before it can appear in REVIEW.md, and explicitly
resists prompt injection embedded in evidence text (never a command, no
matter what it claims to be). A verified claim folds into the existing
Narrative Findings section with (external: {slug}) provenance — one
REVIEW.md schema only, no separate external-findings section.
code-review.md's EXTERNAL_EVIDENCE_BLOCK now restates the four fixed
source-review prohibitions (SAFE-03..06) at the internal-reviewer handoff.

* fix(01-02): gitignore the reviewer-step-dispatch build artifact

01-02 added src/reviewer-step-dispatch.cts but never added its
npm run build:lib output to .gitignore, unlike every sibling
gsd-core/bin/lib/*.cjs generated file. Left it showing as untracked
noise in git status.

* docs(01-04): publish user and command contract for reviewer-lane source review

- Document optional reviewer-lane flags on /gsd-code-review in USER-GUIDE.md
  and COMMANDS.md: opt-in, no source bodies in prompts, no fallback on
  failure, findings independently consolidated into the single REVIEW.md
- Add the same contract to the docs/features/code-review-pipeline.md
  fragment and regenerate docs/FEATURES.md from it
- Preserve /gsd-review as the plan-review command; cross-reference it
  rather than duplicating the reviewer roster
- Pick up docs/INVENTORY-MANIFEST.json and skills/gsd-code-review/SKILL.md
  drift owned by source already shipped in Plans 01-01/01-03 but never
  regenerated (npm run regen:derived had not been run in this worktree)

* docs(01-04): align architecture and agent ownership docs for reviewer-lane trait

- ARCHITECTURE.md: trace the #4209 capability trait (supportsReviewerLanes)
  through the shared dispatchReviewerLanes interpreter to the existing
  review-lane plan/invoke machinery, ending at gsd-code-reviewer as the
  sole REVIEW.md consolidator
- AGENTS.md: document gsd-code-reviewer's full-context verification scope
  and its treatment of external reviewer evidence as unverified input
- No new diagram, abstraction, or config key; docs/CONFIGURATION.md is
  unchanged since the feature adds no setting or default

* fix(01-02): eslint-ignore the reviewer-step-dispatch build artifact

Same gap as the earlier .gitignore fix: 01-02 added
src/reviewer-step-dispatch.cts but never added its generated
gsd-core/bin/lib/reviewer-step-dispatch.cjs output to
eslint.config.mjs's ignore list like every sibling generated file,
so tsc's emitted __importDefault CommonJS-interop var tripped
no-var.

* fix(01-04): add the reviewer-step-dispatch.cjs roster row to docs/INVENTORY.md

01-04 regenerated docs/INVENTORY-MANIFEST.json (which now lists
cli_modules/reviewer-step-dispatch.cjs) but the hand-written roster
row in docs/INVENTORY.md — required by design, since a role sentence
cannot be generated — was never added.

* fix(01-01): update the code-review capability-step fixture for supportsReviewerLanes

refactor-trigger-cli.test.cjs's preservesCodeReviewHookShapeAlongsideRefactorHook
strict-deep-equals the code-review step's exact shape at execute:post; 01-01 added
supportsReviewerLanes: true to that step and this fixture was not updated.

* chore(01-03): acknowledge emitted-doc growth for code-review.md and gsd-code-reviewer.md

Both files grew as a direct, intended consequence of wiring optional
reviewer lanes into /gsd:code-review (the new dispatch_reviewer_lanes
step and the untrusted-evidence consolidation contract) — not
incidental drift.

Emitted-Drift-Ack-Growth: code-review.md — new dispatch_reviewer_lanes step and EXTERNAL_EVIDENCE_BLOCK wiring for optional reviewer lanes (#4209)
Emitted-Drift-Ack-Growth: gsd-code-reviewer.md — untrusted external-evidence consolidation contract for optional reviewer lanes (#4209)

* test(01-05): define WR-01/WR-02 reliability contract for dispatchReviewerLanes

From internal code review: dispatched must be false when zero lanes
actually reached plan(), and a throwing plan()/invoke() for one lane
must not discard results already collected for a sibling lane —
matching the fail-closed pattern gsd-tools.cjs already uses for the
same resolveLanePlan call (#2494/#2605/#1698/#1936/#2073/#2176/#2589/#2794).

Refs: gsd-core-dks.16, gsd-core-dks.17

* fix(01-05): close WR-01/WR-02/IN-01/IN-02 from internal review

- WR-01: dispatched now tracks whether any lane actually reached
  plan(), not results.length — an unresolvable selected slug no
  longer reports dispatched:true.
- WR-02: plan()/writePromptFile()/invoke() wrapped per-lane so a
  throw for one lane can never discard results already collected
  for a sibling lane, matching the same guard gsd-tools.cjs already
  has around the identical resolveLanePlan call.
- IN-01: documents the intentional budget===0-is-unbounded
  convention (#2797) the caller already relies on.
- IN-02: review-lane dispatch-step no longer blocks indefinitely on
  an un-piped interactive TTY; fails closed to empty paths instead.

* docs(01-05): add changeset fragment for PR #17

* fix(01-03): allowlist prompt-injection-scan false positive on the untrusted-evidence contract

agents/gsd-code-reviewer.md's untrusted-evidence section and its
pinning regression test both quote injection phrases as the exact
attack they defend against/detect — same
DEFECT.PROMPT-INJECTION-SCAN-COLLISION class as the existing
allowlist entries, not an actual injection vector.

* test(01-05): extend WR-02 coverage to writePromptFile/invoke throws; DIFF_BASE-empty skip

From CodeRabbit review: WR-02's earlier fix only wrapped plan() —
writePromptFile()/deps.invoke() still ran unguarded, so a throw
there still aborted every later selected lane. Also covers the
dispatch_reviewer_lanes DIFF_BASE-empty-provenance gap (explicit
lanes silently not running when no prior review and no phase-start
commit exist).

* fix(01-05): skip dispatch_reviewer_lanes with a clear warning when DIFF_BASE cannot be resolved

Previously an explicit reviewer-lane request with no prior review and
no resolvable phase-start commit reached dispatch-step with an empty
--base-sha, which fails closed via missing_provenance — correct, but
silent about why explicitly requested lanes didn't run. Now skip
dispatch entirely in that case with a stderr warning naming the
actual cause.

* fix(01-05): wrap writePromptFile/invoke in the same per-lane try/catch as plan()

WR-02's original fix only guarded plan() — a throw from
writePromptFile() or deps.invoke() still aborted the whole dispatch,
discarding results already collected for lanes processed earlier in
the loop. CodeRabbit caught the gap; WR-02b/WR-02c pin it.

* fix(01-05): WR-02b mock must throw only on the first writePromptFile() call

The committed mock threw unconditionally, so codex's retry also threw and
failed for the same reason as claude's — the test could not distinguish
'sibling still runs' from 'sibling also breaks'. Gate the throw to the
first call, matching WR-02/WR-02c's single-failure intent.

* fix(#4209): close review findings from adversarial + critical-code-reviewer pass

Two independent reviews (agy adversarial review, Opus critical-code-reviewer +
ponytail) found 6 Blocking and 7 Required issues in the reviewer-lane dispatch
wiring around dispatchReviewerLanes. All 13 tracked in gsd-core-dks.18-30 and
fixed here:

- dispatch-step's reducer silently swallowed whole-dispatch rejections
  (invalid paths, missing provenance, etc); it now checks parsed.ok/reason.
- spawn_reviewer recomputed its own stale DIFF_BASE, diverging from the
  LAST_REVIEW_COMMIT-aware value dispatch_reviewer_lanes uses on re-review;
  now shares the single compute_file_scope derivation.
- the external reviewer prompt had no actual review request or citation
  requirement, only prohibitions; added both.
- removed the supportsReviewerLanes trait plumbing (capability registry,
  validator, loop-resolver, docs, tests) — it was never consulted by the
  real dispatch path, which gates on explicit CLI flags instead.
- flag-resolution require() was a fragile cwd-relative literal that failed
  silently on non-vendored installs; now resolves via GSD_TOOLS's own
  directory and warns instead of swallowing failure.
- reducer didn't unwrap the @file: overflow protocol for large payloads.
- deduplicated resolveBudget/budgetFor into one resolveLaneBudget.
- lane artifacts now write to a mktemp run dir instead of $PHASE_DIR, so a
  second dispatch can't overwrite prior evidence.
- validatePaths rejects control characters, closing a markdown-injection
  vector into the external prompt via crafted filenames.
- reworded the one line that tripped prompt-injection-scan.sh instead of
  allowlisting the whole production prompt file.
- fixed a stale docstring range and a dispatched-field ordering bug.
- added 3 integration tests executing the actual reducer against synthetic
  dispatch-step JSON, replacing markdown-substring-only assertions.

771/771 tests pass across every touched suite; tsc --noEmit clean.

* fix(#4209): wire supportsReviewerLanes as the maintainer's required reusable trait

The maintainer's approval on issue #4209 explicitly redirected implementation
shape: reviewer-lane dispatch must be a reusable capability/step-dispatch
trait ("supportsReviewerLanes"), not code-review.md hand-wiring the call
itself. My previous commit (e2558326) deleted that trait entirely after
finding it declared-but-never-consulted, which was backwards — the fix was to
wire it, not remove it.

Restores the trait (capability.json, generated registry, validator,
loop-resolver.cts, docs, tests) and wires it for real: dispatch_reviewer_lanes
now resolves its own active hook via `gsd_run loop render-hooks` for the
configured workflow.code_review_point and only proceeds to CLI-flag matching
when supportsReviewerLanes reads true. Explicit flags no longer bypass the
trait; a matching flag with the trait false resolves zero slugs (proven by a
new integration test executing the real fence with both trait states).

Emitted-Drift-Ack-Growth: gsd-core/workflows/code-review.md — the
dispatch_reviewer_lanes step grows a trait-resolution fence (#4209 maintainer
redirect requires the capability layer, not the workflow, own the opt-in
decision).

* fix(#4209): dispatch-step self-verifies the reviewer-lane trait via --cap-id/--point

Both an agy adversarial review and an Opus critical-code-reviewer pass
independently found the same gap in my previous commit (9b2c3773d): the trait
check I wired into code-review.md only protected code-review's OWN
invocation — gsd-tools.cjs's dispatch-step handler still hardcoded
`trait: true` unconditionally, so a second capability declaring
supportsReviewerLanes would get zero enforcement from the shared CLI unless
it correctly re-implemented the ~15-line render-hooks scrape itself. That is
exactly the "each workflow.md hand-wiring the call" the maintainer's redirect
said to eliminate.

Moves the trait check into dispatch-step itself: given --cap-id/--point, it
self-invokes `loop render-hooks <point>` (relocating the one subprocess
code-review.md used to spawn for this, not adding a new one) and derives the
real trait from that capId's active hook, rather than trusting a
caller-passed boolean. code-review.md now only passes
--cap-id code-review --point "$CODE_REVIEW_POINT" and no longer resolves or
gates on the trait itself — the ~20-line scrape it previously carried is
gone. Any other capability opts into the identical enforcement by declaring
the trait and passing the same two flags.

Replaced the two tests that stipulated SUPPORTS_REVIEWER_LANES as an input
variable (they proved a bash branch honors a variable, not that the variable
reflects the real capability manifest) with three integration tests that
invoke the real dispatch-step CLI against the real first-party capability
registry: the real code-review trait resolves true, an unknown --cap-id
resolves false (trait_not_enabled, fail-closed), and omitting
--cap-id/--point entirely resolves false (no context means no opt-in).

Also: reject \x7f/U+2028/U+2029 in validatePaths' control-character check
(agy-F1 was incomplete), and delete the promptWritten per-lane coupling
flag — the prompt write is idempotent, so writing it once per lane instead
of gating on "did any lane write it yet" removes a latent bug where a
deps.plan override that ever varies promptPath per lane would silently skip
writing for a later lane.

Emitted-Drift-Ack-Growth: gsd-core/workflows/code-review.md — net line count
drops (the trait scrape moved into dispatch-step), but the file still grew
this session across multiple commits; acknowledging per the growth-tracking
convention.

* fix(#4209): remove per-run token waste from the shipped prompts

Runtime prompt content, not session tokens: two real, per-invocation token
costs in the code that ships.

1. agents/gsd-code-reviewer.md's critical_rules restated nearly all of
   load_context step 5's ~180-word untrusted-evidence contract in ~90 more
   words, breaking this section's own established terse one-liner style
   (every other rule here is 1-2 sentences). This prompt loads fresh on
   every /gsd:code-review invocation. Shrunk to a one-line cross-reference,
   matching how write_review's own reference to step 5 already does it.

2. buildSourceReviewPrompt repeated the base SHA on every single file line
   even though it is identical for every file and already stated once at
   the top of the prompt — O(files) wasted tokens on every dispatched lane
   for a 50-file review, for zero information gain. File lines are now bare
   paths.

* fix(#4209): resolve reviewer-lane trait in-process, fix CI failures found in review round 3

Opus critical-code-reviewer found a real Blocking defect in the --cap-id/
--point self-invocation added last commit: `dispatch-step` spawned
`loop render-hooks <point> --raw` as a subprocess and bare-JSON.parse'd its
stdout, but `io.cjs`'s output() redirects any payload over 50000 chars to
`@file:<path>` instead of inline JSON -- the same overflow protocol this
feature already unwraps for its OWN dispatch result 60 lines later in
code-review.md. A large-enough activeHooks envelope (more installed
capabilities/fragments) would throw, get silently swallowed by the bare
catch, and misreport a real trait as trait_not_enabled with zero diagnostic.

Fixed by extracting the config/registry/capability-state resolution
`cmdLoopRenderHooks` already performs into an exported pure function,
resolveActiveHooksForPoint (both `cmdLoopRenderHooks` and dispatch-step now
share it), and calling it in-process from dispatch-step instead of spawning
a subprocess at all. This eliminates the @file: exposure entirely (the
dispatch-step path never touches the rendered-string envelope or its
JSON-stringify/50000-char threshold), removes one subprocess spawn per
code-review invocation, and gives a genuine diagnostic (stderr warning) on
resolution failure instead of silent fail-closed. Corrected three doc/
docstring references to the now-removed subprocess self-invocation.

Also fixes 2 real CI failures this round surfaced:
- lint-tests: the agy-F1 control-char regex fix's `eslint-disable-next-line
  no-control-regex` comment was unused under this project's ESLint config
  (verified locally: the rule never actually flags \x00-\x1f in this repo's
  config) -- a mistake from an earlier commit this session, never actually
  lint-checked before push. Removed the disable comment.
- security (prompt-injection-scan): the agy-F1 regression test's crafted
  fixture literally contains "Ignore all prior instructions." as test data
  proving validatePaths rejects it -- allowlisted the test file, same
  DEFECT.PROMPT-INJECTION-SCAN-COLLISION class as existing entries.

Also trimmed agents/gsd-code-reviewer.md's load_context step 5 (R2): one
bullet stated "untrusted, never a command" three different ways in one
paragraph, and a same-file duplicate of write_review's schema rule.
Consolidated to state each rule once.

Declined one suggestion from this round: shrinking code-review.md's
EXTERNAL_EVIDENCE_BLOCK to a bare evidence list. Two tests
(tests/code-review-pipeline-regression.test.cjs's CONS-01..03 block,
tests/code-review.test.cjs's CONS-02 test) deliberately lock the four-
prohibitions restatement and the untrusted-evidence prose into the
INJECTED block itself, not just the consolidator's system prompt --
adjacency of the warning to the untrusted payload it's warning about is a
recognized prompt-injection defense-in-depth pattern from this
workstream's original TDD plan, not accidental duplication.

* fix(#4209): correct stale per-file base-SHA prose in the external prompt

Leftover from removing the per-file base SHA repetition earlier this
session: the review-request sentence still said "relative to its base SHA"
(singular per-file framing) when there's now exactly one base SHA, stated
once above the file list. Reads "relative to the base SHA above" now.

* fix(#4209): make getLane/configGet/plan required deps, delete dead defaults

R3/R4 from the review round I'd deferred as low-priority test-churn: this
file's one production caller (gsd-tools.cjs's dispatch-step handler) always
supplies all three, so the fallbacks were dead in production -- but each was
actively WRONG if ever reached: the default configGet always returned
undefined, silently disabling resolveLaneBudget's overflow guard; the
default getLane looked up only first-party REVIEWER_LANES, diverging from
production's overlay-merged roster; the default plan skipped per-host effort
resolution entirely.

These defaults were introduced by this PR's own earlier work (this file did
not exist before #4209 -- first commit a760bfcda, 01-02), not inherited from
elsewhere, so there's no external caller depending on the lenient contract.

Turned out free to fix: making the three deps required and deleting
defaultGetLane/defaultPlan needed zero test changes -- every existing test
that actually reaches the per-lane loop already supplies getLane/plan
explicitly, and configGet's only real dependent (the budget-overflow tests)
already supplies it too. 788/788 tests pass unchanged, tsc/lint clean.

* fix(#4209): define depth semantics for the external reviewer lane

Verified this was a real bug, not a match to existing convention as I'd
claimed when declining the suggestion earlier this session: the internal
gsd-code-reviewer agent's own system prompt carries a full <depth_levels>
block defining what quick/standard/deep mean and do (agents/gsd-code-
reviewer.md:68-99). The external reviewer lane has no access to that
persona at all -- it only ever sees buildSourceReviewPrompt's bounded text,
which sent the bare depth label with zero definition to a third-party CLI
with no other source of truth for what "standard" means.

Added depthMeaning(), condensed from the internal reviewer's own
<depth_levels> definitions so the two stay consistent, and interpolated it
into the review-request sentence. 150/150 tests pass, tsc/lint clean.

* fix(#4209): merge dispatch_reviewer_lanes' split fences into one shell invocation

CR-01 (Opus critical-code-reviewer, confirmed by direct execution): the
roster-matching fence set EXPLICIT_JOINED/EXPLICIT_REVIEWER_SLUGS, and a
SEPARATE later fence read them via ${#EXPLICIT_REVIEWER_SLUGS[@]} to decide
whether to dispatch at all. This file's own documented rule (its
depth-resolution guard, stated explicitly a few hundred lines earlier) is
that a guard and the extraction it protects must run as one shell
control-flow decision, because markdown-fenced blocks do not share shell
state -- this step violated its own file's rule for the entire feature's
gating condition.

Merged the roster-resolution fence and the dispatch-decision fence into one
continuous bash block, removing the intervening prose that split them.
Fixed the stderr-based failure detection in the same edit (RQ-01: checking
whether stderr is non-empty misfires on any benign Node warning; now checks
the actual exit status of the roster-resolution command).

Verified by extracting the merged fence and executing it standalone, driving
both branches: --codex resolves EXPLICIT_JOINED=codex, SLUGS_COUNT=1, and a
real dispatch-step call succeeds; no flags resolves EXPLICIT_JOINED empty,
SLUGS_COUNT=0, dispatch-step never invoked (COMP-01). 141/141 workflow tests
pass, tsc/lint clean.

* fix(#4209): depthMeaning accuracy, injection defense on all embedded fields, hoisted prompt write

Batch of Required/Suggestion fixes from the Opus critical-code-reviewer +
writing-for-agents pass:

- CR-02/CR-03: depthMeaning() dropped real categories from quick (empty catch
  blocks, commented-out code) and deep (error propagation, state mutation
  consistency, circular dependencies) relative to the real <depth_levels>
  block, and had zero test coverage. Restored full accuracy and added tests
  that read the real agents/gsd-code-reviewer.md file directly, so drift
  between the two can't recur silently. Unrecognised depth now normalizes to
  standard's definition, matching that agent's own documented rule, instead
  of rendering an undefined bare label.

- RQ-04: depth/baseSha/repoRoot/runDir land in the same markdown prompt
  `paths` does, but weren't checked for control characters like paths were
  (agy-F1's original finding). Hoisted CONTROL_CHAR to module scope and
  applied it to all four fields at the same provenance-check boundary.
  runDir previously had zero validation at all.

- S1: deleted the dead `identity` parameter on `invoke` -- the one production
  caller already ignores it, no test read it by name.

- S2: hoisted the shared prompt write above the per-lane loop -- promptPath
  is derived from runDir alone (constant across lanes by construction), so
  writing it once is both correct and cheaper than the per-lane write R1
  introduced earlier this session. Discovered and fixed a real regression
  from the naive version of this hoist: an unguarded throw would have
  escaped dispatchReviewerLanes as an uncaught exception instead of a clean
  per-lane failure. Added a new PROMPT_WRITE_FAILED whole-dispatch reason,
  matching the existing validatePaths/MISSING_PROVENANCE halt pattern, with
  a dedicated regression test.

- S3: moved `planned = true` past the budget-overflow gate, so `dispatched`
  only reports true once a lane has cleared BOTH plan and budget checks.

- S5: relayed gsd-code-reviewer.md's own "performance issues are out of
  scope unless also correctness issues" policy into the external-lane
  prompt, which previously had no such guidance and could return findings
  the internal reviewer's own contract excludes.

- RQ-05 (partial): shrunk this file's own header docstring's restatement of
  the trait-reuse architecture to a pointer at
  gsd-core/references/loop-hook-dispatch.md, the canonical home.

234/234 tests pass across the full reviewer-lane test suite, tsc/lint clean.

* fix(#4209): dedupe roster-merge logic, consolidate trait architecture prose, add step completion criterion

RQ-02: added a `review-lane explicit-from-argv` subcommand that reuses the
SAME merged-roster logic (`laneBySlug`) `dispatch-step`/`plan`/`invoke`
already share. code-review.md's ~18-line inline `node -e` reimplementing
`loadRegistry`+`mergeReviewerLanes` (a rename-only copy of the block in
gsd-tools.cjs) is now a single call to this subcommand -- the exact
violation code-review-flags.cjs's own header warns against ("this is the
canonical flag-parsing surface -- do not replicate inline bash parsing").

RQ-03: an empty --cap-id XOR --point now warns distinctly from the
legitimate no-context opt-out (both absent) -- a caller that named a
capability without its point was silently indistinguishable from a correct
opt-out. Also hardened the CODE_REVIEW_POINT config-get fallback: it only
ever fires when the config-get COMMAND ITSELF fails (config-get already
resolves the manifest's own schema default in the normal case), but that
failure was previously silent.

RQ-05/W-01/W-12/W-13: the "supportsReviewerLanes is a reusable trait
resolved inside dispatch-step" explanation was restated in full in 5
places across this session's own review cycles. Consolidated to ONE
canonical statement in gsd-core/references/loop-hook-dispatch.md; the other
4 (this file's own header, gsd-tools.cjs's comment, docs/ARCHITECTURE.md,
code-review.md's step-opening comment) now point at it instead.

W-05/W-06: loop-hook-dispatch.md described "false or non-boolean" as two
inert cases when capability-validator.cjs already rejects non-boolean at
load -- restated as the two cases that actually reach this code. Removed a
"do not hand-roll trait resolution" prohibition whose target no longer
exists once the positive description precedes it.

W-04: deleted a no-op sentence in agents/gsd-code-reviewer.md ("missing
block means proceed as normal") -- an absent optional block already means
proceed as normal without being told.

W-08/W-09: replaced longhand "zero selection/plan/invoke calls" and the
made-up compound "byte-for-behavior [un]changed" with the token this
session's own docs already coined for this concept (inert) and the word
that means what byte-for-behavior was reaching for (unchanged).

W-10: dispatch_reviewer_lanes had no completion criterion -- added one
sentence naming the checkable end state (EXTERNAL_EVIDENCE_BLOCK is set,
either populated or empty). This exact sentence would have caught the
cross-fence bug fixed two commits ago at authoring time.

Declined from this round, with reasoning: W-02/W-03 (trim the
untrusted-evidence restatement in EXTERNAL_EVIDENCE_BLOCK/critical_rules) --
two tests deliberately lock this as intentional adjacency-based
prompt-injection defense-in-depth, not accidental duplication (see this
branch's own earlier commit). S4 (wrap LANE_RUN_DIR in a creation-site
`trap ... EXIT`) -- would fire at the end of the CREATING fence, before
spawn_reviewer's agent ever reads the evidence files, given this file's own
documented fenced-block execution model; the existing named cross-reference
between creation and cleanup already satisfies the co-location concern
without introducing that regression.

853/853 tests pass across the full reviewer-lane test suite, tsc/lint clean.

* fix(#4209): merge CODE_REVIEW_POINT into dispatch_reviewer_lanes' one fence, stop test from spawning real codex

Round-5 review (agy) found the same cross-fence-split bug CR-01 already fixed
for EXPLICIT_JOINED/EXPLICIT_REVIEWER_SLUGS: CODE_REVIEW_POINT's config-get
fallback lived in an earlier, separate fence from the fence that consumes it
via --point, split only by prose (not a guard, per this step's own documented
rule). Merged into the single continuous fence and added a structural test
asserting exactly one bash fence in the step.

The new end-to-end regression test for this used --codex, which drives the
fence's real `review-lane dispatch-step` call and, with the codex binary
present on PATH, spawns the real external CLI — which then blocks on
interactive auth with no stdin (BL-01). Stubbed gsd_run for
`review-lane dispatch-step` only (captures argv instead of executing),
keeping the real config-get/explicit-from-argv calls the test is actually
about.

* fix(#4209): split control-char vs missing provenance reason, realpath-check path escapes, stale comment

Round-5 review (Opus) warning-tier findings:

- WR-04: MISSING_PROVENANCE covered both "field absent" and "field present but
  a control-character injection attempt" — a caller distinguishing a config
  problem from a security event couldn't tell them apart. Split into
  MISSING_PROVENANCE (absent) and INVALID_PROVENANCE (present but invalid).
- WR-05: validatePaths' containment check was lexical only (path.resolve),
  so a symlink whose own path sits inside repoRoot could still point outside
  it. Added an fs.realpathSync check (ENOENT-tolerant — a git-diff path can
  legitimately name a file already deleted in a stale worktree), realpathing
  repoRoot itself too so a symlinked repoRoot (e.g. /tmp on macOS) doesn't
  false-positive-reject its own real children.
- WR-08: a comment in the per-lane loop still said a throwing writePromptFile()
  was caught there — stale since the prompt write was hoisted above the loop
  in an earlier round.

WR-03 (validate depth against the quick/standard/deep enum) was considered
and declined: this dispatcher is deliberately capability-neutral (see the
existing "synthetic step context" test, which passes a non-code-review depth
label on purpose to prove no code-review-specific special-casing exists).
WR-01 (double registry load), WR-02 (trim-vs-hard-fail budget semantics), and
WR-07 (reason omitted on the aggregate return) were verified against source
and are not bugs — see review notes.

* docs(#4209): document LANE_RUN_DIR's early-exit trade-off as accepted, not a gap

Round-5 review (Opus, BL-03) flagged that an early exit between
dispatch_reviewer_lanes and commit_review leaks the run-scoped temp dir. A
trap-based cleanup was considered and rejected: if a step genuinely runs as
a separate process, a trap set at creation time would fire at the end of
that SAME fence, deleting the directory before spawn_reviewer/commit_review
ever read it — worse than the leak it would fix.

review.md's own gather_context/cleanup pair for the identical resource class
(a run-scoped reviewer temp dir) already makes and documents this exact
trade-off: cleanup runs only on a documented success path, and a leftover
$TMPDIR entry is explicitly called cheaper than destroyed evidence. Recording
that precedent here so this isn't re-raised as a live gap in a future review.

* fix(#4209): register the WR-05 symlink-escape test's synthetic docs/ path

reviewer-step-dispatch.test.cjs's "capability-neutral reuse" fixture passes
paths: ['docs/spec.md'] as a synthetic, never-read path proving the
dispatcher has no code-review-specific special-casing. lint-docs-guard-
registration correctly flagged this as an unregistered docs/ path reference —
add the docs-guard-exempt marker and its pinned baseline entry, the same
pattern every other synthetic docs/ literal in this test suite already uses.

* fix(#4209): backfill changeset pr: field with the real upstream PR number

changeset-lint's fail_pr_field_drift caught the fragment still pointing at
the fork PR (17) instead of the upstream one (open-gsd/gsd-core#4323) this
branch is now also open against.

* docs(#4209): amend ADR-2782 for the supportsReviewerLanes step-trait seam

trek-e's review (2026-09-07, gsd-core#4323) found a real ADR gap: every
decision in ADR-2782 (D1-D9) and every prior dated amendment governs the
`role: "reviewer"` capability body and its one consumer, /gsd:review. This
PR's actual new seam - a `supportsReviewerLanes: true` trait on an ordinary
feature capability's `steps[]` entry, projected through loop-resolver.cts
and resolved in-process via resolveActiveHooksForPoint - is a different
capability axis (steps/gates/contributions) that the ADR's own scope note
explicitly places out of reach. Per docs/contributor-standards.md's
"Amending an accepted ADR", an in-place dated section is the established,
lighter-weight path for an addition that stays within the ADR's existing
decisions - used twice already in this same file - so this appends a third
dated entry documenting the new seam, its consumer, and why it reuses the
existing D1-D9-governed plan/invoke machinery rather than adding a second
one. No decision is reversed; no new Amends/Amended-by pair is needed since
the steps/gates/contributions axis already carries reciprocal links to
ADR-857 and ADR-894.

* fix(#4209): close two test-quality gaps trek-e's review found

Minor 1: validatePaths (a path-shape parser guarding the prompt-
injection/path-traversal trust boundary) had only example-based coverage,
violating ADR-456's rule that parsers/budget limits carry at least one
fast-check property test. Adds three: safe-segment paths are never
rejected, a single leading "../" always escapes the one-segment repoRoot,
and a control character anywhere is always rejected - one property per
rejection reason validatePaths owns.

Minor 2: the budget-overflow check (`estimatedTokens > budget`) was only
ever exercised far below budget or at budget:0 (unbounded), never at the
exact threshold crossing where a `>` vs `>=` off-by-one would hide. Adds
three exact-boundary tests using the real estimateTokens/
buildSourceReviewPrompt the module calls internally, so the resolved
token count is exact rather than approximated: budget == estimate (must
pass), budget == estimate - 1 (must fail), budget == estimate + 1 (must
pass).

Also extracts okPlan()'s fixture timeoutMs into a named constant -
local/no-adhoc-timeout-literal (#4446) landed on next after this branch
was authored and flagged the pre-existing literal on rebase; it is fixture
data for a synthetic plan object dispatchReviewerLanes never waits on, a
distinct class from tests/helpers/timeouts.cjs's real subprocess norms.

* fix(#4209): update docs-guard-registration baseline for the new ADR citation

reviewer-step-dispatch.test.cjs's new fast-check property tests cite
docs/adr/456-test-rigor-architecture.md in a justifying comment (never a
real read). lint-docs-guard-registration fingerprints every docs/ path
string an exempted test file mentions and fails on drift so a human
re-confirms the exemption still holds - re-confirmed, and the baseline is
updated to match.

* fix(#4209): point changeset pr: field at the fork PR for CI validation

changeset-lint's fail_pr_field_drift check compares the fragment's pr:
field against the PR the CI run is actually attached to (GITHUB_EVENT_PATH),
not a fixed target. Rehearsing this branch on fork PR
davdittrich/gsd-core#17 needs pr: 17 to pass that check; the prior commit's
pr: 4323 (the real open-gsd upstream PR number) is correct for that PR but
fails here. Backfill to 4323 happens again, as the last commit, immediately
before the approved push to open-gsd#4323 - never leaving pr: 17 on the
branch that ships upstream.

* fix(#4209): reject promptChannel:none lanes from source-review dispatch

CodeRabbit found a real scope mismatch: coderabbit's lane declares
promptChannel: 'none' and reviews the working tree on its own terms,
fed nothing (review.md:367). Silently dispatching it through
dispatchReviewerLanes would ignore the bounded paths/depth/baseSha scope
buildSourceReviewPrompt promises and let the lane review whatever it
independently sees fit, violating this interpreter's own scoped,
metadata-only contract. Reject before plan()/invoke(), same as an
unresolved slug.

* fix(#4209): scope CONS-02 test to the evidence-block line, not the whole file

CodeRabbit found the whole-file match on workflowContent would still
pass if UNVERIFIED and re-open/reopen appeared in two unrelated parts
of this 1000+-line workflow, proving nothing about the actual evidence
block's contract. Line-filtered via splitLines (not a bare-\n regex
spanning readFileSync content) so this stays CRLF-portable and passes
local/no-unbounded-quantifier and local/no-crlf-fragile-split.

* fix(#4209): guard DISPATCH_JSON substitution and capture its stderr

CodeRabbit found the dispatch-step command substitution unguarded: a
non-zero exit could leave DISPATCH_JSON empty (or halt the step under
errexit with no warning), and the downstream reducer would only ever
report the generic unparseable_dispatch_output reason, discarding the
command's own diagnostic. Guarded like the existing CODE_REVIEW_POINT/
EXPLICIT_JOINED calls above it: capture stderr to a temp file, surface
it in a warning on failure, and fall back to a parseable dispatch_
command_failed JSON stub so the reducer's existing reason-reporting
path still fires.

* docs(#4209): fix byte-for-behavior wording and missing colon, regenerate

CodeRabbit found "byte-for-behavior" should read "byte-for-byte" (the
established repo term for output-identical unchanged behavior) and a
missing colon after the bold "Optional external reviewer lanes (#4209)"
lead-in in docs/features/code-review-pipeline.md. Fixed in the two
hand-authored sources (commands/gsd/code-review.md, docs/features/
code-review-pipeline.md) and regenerated the two derived projections
(skills/gsd-code-review/SKILL.md via gen-plugin-skills.cjs, docs/
FEATURES.md via gen-features.cjs) so they stay in sync.

* fix(#4209): drop the fabricated DISPATCH_JSON fallback stub (Windows CI)

The prior fix's fallback `DISPATCH_JSON='{"ok":false,...}'` embeds
double-quoted JSON keys inside a single-quoted shell literal. That
extra quote density, inside an already quote-heavy ~8KB driver string,
passed bash -n and the full local suite on Linux but broke Windows
Git-Bash: `dispatch_reviewer_lanes computes CODE_REVIEW_POINT ... end
to end (#4209 round 5)` failed on two Windows CI shards with `bash -c:
unexpected EOF while looking for matching '''` — a Windows argv-to-
command-line re-quoting edge case, reproducible on rerun, not a flake.
Root-caused via gh api job logs plus a byte-identical local
reconstruction of the test's own driver script.

Fix: drop the fabricated stub. The downstream node -e reducer already
falls back to reason `unparseable_dispatch_output` on any JSON.parse
failure, so an empty/partial DISPATCH_JSON on command failure is still
handled correctly, with zero new quoting risk.

* revert(#4209): drop the DISPATCH_JSON stderr-guard nitpick (Windows CI)

Two materially different mechanisms for the same CodeRabbit Nitpick
("Trivial | Quick win") both broke Windows Git-Bash reproducibly:
a single-quoted JSON-literal fallback ("bash -c: unexpected EOF ...
matching '''") and, after removing that, a plain `head -1 "$VAR"`
inside a nested command substitution ("unexpected EOF ... matching
'"'"). Both passed bash -n and the full local suite on Linux every
time; both failed the SAME test deterministically on Windows CI. Two
attempts at the same class of fix (nested-quote construction near
this exact step) is the retry limit - reverting to the original,
already-shipped, Windows-verified unguarded form rather than
continuing to guess at a third quoting mechanism for a Trivial-
severity nitpick. Logged as bug-221/bug-222 in .wolf/buglog.json for
anyone attempting this again: the fix belongs outside this specific
markdown-fence-driver test harness (e.g., a real .sh helper script)
if it's worth doing at all.

* fix(#4209): backfill changeset pr: field to the real upstream PR before push

Fork validation (davdittrich/gsd-core#17) needed pr: 17 to satisfy
changeset-lint's PR-number check while rehearsing there; this is the
last commit before the approved push to the real upstream PR
(open-gsd/gsd-core#4323), so the field points at that PR number again.

0396d9cab1 enhance(#2483): stop the claude reviewer lane from inheriting CLAUDE.md + auto-memory (#2493)
* enhance(#2483): env-guard the claude reviewer leg against CLAUDE.md injection

The claude reviewer in workflows/review.md was a bare headless `claude -p`
spawn run from the project cwd, so it inherited the invoking user's global
CLAUDE.md, the project CLAUDE.md, and Claude Code auto-memory.

That made it the only reviewer leg seeing anything beyond the prompt file.
gather_context assembles PROJECT.md, the roadmap section, every PLAN file,
CONTEXT.md, RESEARCH.md and REQUIREMENTS.md into the prompt before any
reviewer runs; the gemini leg receives only that prompt and the codex leg
runs --ephemeral. Beyond the measured ~4k tokens/spawn, the asymmetry cuts
at the workflow's own premise: "independent review" meant something
different for the claude leg than for the other two.

Guard both dispatch lines with a per-invocation
`env CLAUDE_CODE_DISABLE_CLAUDE_MDS=1`. `env`, never `export` — the flag
must not leak into the orchestrating session (which may itself be Claude
Code on the SELF_CLI="auto" path) or into any later spawn.

review.md is the only claude -p call site in the installed tree, so this is
two lines on one surface. The self-skip logic is untouched.

* enhance(#2483): fix CRLF-fragile split and regenerate workflow baselines

Two CI failures from the first push, both mine:

1. lint-tests: the new regression test split readFileSync content on a
   literal "\n". On a Windows git-autocrlf checkout that leaves a trailing
   "\r" on every line (local/no-crlf-fragile-split). Use .split(/\r?\n/).

2. golden-install-parity / workflow-size-budget / workflow-compat: editing
   gsd-core/workflows/review.md changes its content hash and byte size, and
   both are pinned in committed baselines. Regenerated via the repo's own
   generators (npm run size:baseline, npm run gen:golden).

The regenerated diffs are review.md-only: exactly one hash line per
golden-install-parity fixture and one size entry in workflow-size-baseline
— no unrelated drift swept in.

Full suite now green locally: 2113 pass, 0 fail, 3 skipped (run with HOME
and CLAUDE_CONFIG_DIR overridden to throwaway dirs; live profile verified
untouched afterward).

* enhance(#2483): adapt guard-test matcher to the effort-args dispatch reshape

The effortSurface wiring (#2481) reshaped the bare-model dispatch to
`claude $CLAUDE_EFFORT_ARGS -p -`; the invocation matcher's dash-first
form could no longer see it, and the count assertion failed exactly as
designed. The matcher now tolerates variable expansions between `claude`
and its first literal flag. Negative-controlled both ways: a stripped
guard and a deleted dispatch line each still fail.

* enhance(#2483): also guard the claude leg against auto-memory injection

CLAUDE_CODE_DISABLE_CLAUDE_MDS suppresses CLAUDE.md file loading;
auto-memory is an independently-toggled mechanism with its own flag.
Add CLAUDE_CODE_DISABLE_AUTO_MEMORY=1 to both dispatch lines, correct
the docs/COMMANDS.md and changeset claims that credited the first flag
with covering auto-memory, and extend the regression test to require
both flags on every claude invocation (negative-controlled: 2/4
assertions fail with the new flag removed).

* enhance(#2483): match the claude binary in command position, not argument position

The line-oriented invocation matcher counted any line where the token
`claude` was followed by a flag. #2589 (landed on next as 920a5f3f)
reshaped the effort-args lookup from

  --host claude 2>/dev/null | jq -r '.effort_argv_string // ""'

to

  --host claude --pick effort_argv_string

which put a flag immediately after `claude` and made the config query
read as a third claude dispatch, failing the count assertion.

The defect class is a binary name in *argument* position being read as a
command. Fixed at the class rather than the instance: tokenise the line
and skip any `claude` whose preceding token is a flag. That also covers
the latent sibling one line away in review.md (`command -v claude`),
which escaped today only because its next token is a redirect.

Negative-controlled four ways: stripping CLAUDE_CODE_DISABLE_AUTO_MEMORY=1
fails, stripping the whole env guard fails, adding a genuine third
unguarded dispatch (`timeout 900 claude --output-format text -p -`) still
fails — so the narrowing did not blind the matcher to reshapes, which is
the property the count assertion exists for — and the pre-#2589 jq form of
the lookup still passes, so the matcher is not pinned to today's base.

* enhance(#2483): carry the claude reviewer's memory guard as declared lane data

ADR-2782 Phase 5b replaced the hand-authored per-CLI dispatch legs in
review.md with the declared lane table, so the two `env`-prefixed shell
lines this PR previously added no longer have a surface to live on. The
guard is reimplemented where the lane contract now lives.

`SpawnInvoke` gains an optional `env`, the claude lane declares the pair,
the resolver folds own string-valued entries into `SpawnPlan.env` (absent
or empty resolves to null, so the runner has one shape to test), and the
runner passes it to spawn. Production merges it OVER `process.env` into a
fresh object for that one child, so nothing reaches the orchestrating
session or any other lane in the run.

Declared data rather than a handler (D6): the pairs are static per lane,
which is precisely what the manifest vocabulary is for. The capability
manifest carries the same field, because the lane-fidelity test compares
manifest and descriptor over the union of `invoke`'s keys.

The regression test is rewritten against the resolver and runner rather
than review.md's text. It gains the property the source-text assertions
could only approximate: that `process.env` is never mutated.

Scope boundary, asserted rather than left in prose: `env` is not part of
the trust-disclosure surface, which is safe only while no manifest body
reaches the resolver — the registry's reviewer bodies contribute slugs to
the parity check and execution resolves from `REVIEWER_LANES`. The new
test fails first if that ever changes.

* enhance(#2483): restate the guard's mechanism in the docs and changeset

Both described the fix as two `env`-prefixed dispatch lines, which is the
surface ADR-2782 Phase 5b removed. The user-visible behaviour is
unchanged; the carrier is not, and a changeset that ships a description
of a mechanism the tree does not have is a CHANGELOG entry nobody can
verify against the code.

* enhance(#2483): cover the production spawn wiring end to end

The unit tests stop at the runner's `deps.spawn` seam — every one injects
a spy. Production supplies that seam in `gsd-core/bin/gsd-tools.cjs` as a
hand-written object no test constructs, so the chain could be correct all
the way to `SpawnPlan.env` and the merge could still be wrong or absent
with the suite green. Deleting those four lines was the one mutation that
left every other control silent.

This runs the real `spawnSync` through `gsd-tools review-lane invoke`,
with a `claude` shim on PATH that records the environment it was handed.
It asserts both halves in one test: the pair arrives, and an unrelated
inherited variable survives — a wiring that REPLACED the environment
rather than merging over it would satisfy the first and break every
lane's PATH and HOME.

POSIX-only; mediating a Windows `.cmd` shim is a separate concern the
repo already tests on its own.

Noted rather than fixed: `timeout`, `killSignal`, `maxBuffer` and
`shell: false` on that same object are equally uncovered. That is the
epic's gap, not this change's, and closing it is not in scope here.

* enhance(#2483): validate the invoke.env shape and register it as spawn-only

`env` was the one spawn-invoke field with no shape enforcement: every sibling in
`validateSpawnInvoke` is checked, and a manifest declaring `env` as an array, a
string, a number, or an object with non-string values passed validation in
silence. That matters more than an ordinary schema gap here, because
`resolveLanePlan` DROPS a non-string value rather than coercing it — so an
unvalidated manifest declares a pair that never reaches the spawn, which is the
failure a memory guard can least afford.

Two registrations, not one. `env` was also absent from
`SPAWN_ONLY_INVOKE_FIELDS`, which is the list the openai-http arm rejects
against — so `invoke.env` was accepted on a transport that issues an HTTP POST
and has no child environment at all. It was the only spawn-shaped field accepted
there; the other six each produce two errors. Self-found while sweeping the
class, not raised in review.

Keys are held to the portable POSIX environment-name grammar. That is a policy,
not a claim about what an environment can hold: measured, only NUL is actually
rejected by `spawnSync`, while `=`, a leading digit, a dash and a space are all
carried through to the child (an `A=B` key arrives as the raw entry `A=B=value`).
They are refused because a name outside the grammar is not portably addressable
by the program meant to read it.

`__proto__` is refused for a different and concrete reason. It passes that
grammar and is a real own key once a manifest is JSON-parsed, but assigning it
onto a plain accumulator goes through the inherited `__proto__` setter rather
than creating an own property — and for the string values this field permits the
setter is a no-op that does not even change the prototype. The pair would
validate and then simply vanish before the spawn. (An environment CAN carry a
literal `__proto__` entry; this is about the resolver's accumulator, and the
error message says so.)

Deliberately narrower than the sibling reserved-name guards in this file, which
also reject `constructor`/`prototype`: those guard bracket lookups that resolve
prototype members, whereas this reads via `Object.keys` plus an own-value read,
where `constructor` assigns as an ordinary key the spawn could carry.

`effortChannel` is deliberately left in neither field list: ADR-2782 D2 defines
it for both transports, so it is shared rather than spawn-only.

Reversion-controlled, three mutations, all three fire a named test: dropping
`env` from the discriminator fails `httpTransportRejectsEnv`; removing the
`__proto__` arm fails `envRejectsProtoKeyThatWouldSilentlyVanish`; disabling
the block fails four.

(#2483)

* enhance(#2483): amend ADR-2782 D2 for the invoke.env vocabulary widening

D2 records the spawn `invoke` shape as a closed vocabulary, and its Amendments
section carries a dated entry for every prior widening (Phase 1 #2794, Phase 2
corrections #2795, Phase 5b #2799). This change extended that vocabulary in code
without touching the ADR governing it, so the ADR contradicted the
implementation — and the repo's own convention, recorded in CONTEXT.md, is that
the ADR is amended in the same PR precisely because the prior widenings did it
correctly.

Adds the `invoke.env` row to the D2 table and a dated Amendments entry.

The entry also corrects the authority this change cited. The source comment
pointed at D6, which governs the closed `handler` enum — imperative behavior
admitted first-party — and says nothing about the `invoke` field vocabulary.
That is D2's territory, so the citation never covered the gap.

Two claims are corrected rather than restated, both about the trust boundary
that justifies leaving `env` out of the D5 disclosure signature:

- The regression test does not enforce that boundary. On one forged lane it
  shows the resolver folds whatever it is handed, so a future path feeding it
  manifest lanes would not make any assertion in that test fail. Its comment
  claimed it "will fail first"; that was wrong, and both the comment and the
  ADR now say the boundary is a property of the production call chain instead.
- The ADR is internally inconsistent on whether third-party manifest lanes
  execute at all: Consequences says adding a reviewer needs "no core patch",
  while `gsd-tools.cjs` rejects every slug absent from the first-party
  REVIEWER_LANES map. CONTEXT.md, `workflows/review.md` and the resolver's own
  header take the first view. #2483 did not create that inconsistency and does
  not resolve it; the entry records it rather than settling it in its own favour.

(#2483)

* enhance(#2483): document invoke.env in the capability-manifest reference

ADR-2782 points capability and plugin authors at
`docs/reference/capability-manifest.md` as where the lane vocabulary must be
visible, and its `invoke` row enumerates the spawn sub-shape field by field.
`env` was absent from that table while being part of the real shape, so the one
document a third-party capability author would actually consult to learn the
field exists did not mention it.

Squarely Diataxis reference material — a field-by-field schema description — so
it goes here rather than in the user-facing prose, which was already updated.
States the constraints a manifest author can actually trip, and is explicit that
the name grammar is a portability policy rather than an OS limit, so a reader
does not take it for a claim about what an environment can hold.

(#2483)

* enhance(#2483): disclose and sign the reviewer lane's env and residual invoke fields

`invoke.env` was undisclosed at install time. That was defensible while manifest
lanes could not execute — the premise this PR's own ADR amendment recorded — and
#2927/#3062 retired it: `routeReviewLane` now merges installed overlay `reviewer`
bodies into its lane map via `mergeReviewerLanes`, which is a field-identical merge
by ADR-2782 D1 and deliberately does not deep-validate. An overlay's whole `invoke`
therefore reaches `resolveLanePlan`, and `env` reaches the spawned child. A consented
third-party capability could set `NODE_OPTIONS=--require ./evil.js` on a reviewer lane
with no install-time disclosure and no re-consent.

The same file already decided what `env` means in a manifest: MCP servers fold it into
the disclosure signature and render each key and value in the consent prompt, with an
inline rationale naming this exact shape. Reviewer lanes get the identical treatment.

`env` was the ninth unsigned invoke field, not the first. `defaultHost` (the manifest's
OWN fallback egress host, used whenever the config key resolves to nothing),
`path`, `outputChannel`/`outputArg`, `modelArg`, `effortChannel` and `modelDiscovery`
all reach `resolveLanePlan` and none was bound. Enumerating a ninth name leaves the
tenth open, so the lane signature carries a RESIDUAL of every other declared `invoke`
key — the completeness backstop `rawConfig` already gives the MCP line (#1459 finding 5),
and the "sign the whole object" remedy the recorded decision on this class prefers.

`defaultHost` is also rendered: `resolvedHost` comes from user config, so a lane whose
key is unset displayed "(unresolved …)" — which reads as "no destination" — while the
runtime egresses the plan and review text to the address the manifest picked.

D4.5 is preserved one level down: the extra element is appended ONLY when the lane
declares something beyond the eight already-bound fields, so an env-free lane's
signature stays byte-identical and no already-consented capability is re-prompted for
a field it does not use. A lane that does declare one re-consents, which is the point.

Execution-primitive env names are FLAGGED in the prompt, not refused in the validator.
A denylist cannot be the boundary here: `PATH` alone is a complete execution primitive
for a spawn lane and can never be refused, the child is an arbitrary third-party binary
so the true set spans every interpreter's injection vars, and the MCP `env` this mirrors
refuses nothing and discloses everything. Missing a name costs a quieter line, never a
boundary.

Refs #2483.

* enhance(#2483): exercise the real overlay merge path in the guard test

The test named for the manifest/first-party boundary did not test it. It built a
forged lane locally, handed it straight to `resolveLanePlan`, and asserted that
`REVIEWER_LANES` did not contain it — so no assertion in it depended on the claim its
name made, and a code path that fed manifest lanes to the resolver would not have made
it fail. Its own comment said as much, and named the production chain as the real
carrier of the guarantee: "gsd-tools.cjs builds its lane map solely from REVIEWER_LANES".

That sentence is now false. #3062 merged overlay reviewer bodies into that map, so the
test's premise and its subject both moved.

The replacement routes through `mergeReviewerLanes` — the real helper the production
path calls — and asserts the overlay lane is admitted, resolves, and carries its `env`
into `SpawnPlan.env`. That makes the security property falsifiable instead of narrated.
It then asserts what now backs it: the env is disclosed on the surface, rendered key
and value in the consent prompt, flagged when the name is an execution primitive, and
bound to the signature so a value change, an addition, or a removal each force
re-consent.

Three further cases, because the finding's generative half is what stops it recurring:
the residual backstop is asserted against five fields including one that does not exist
(`aFieldThatDoesNotExistYet`), so a future vocabulary widening cannot silently re-open
this; a fully-enumerated lane is pinned to its original 8-tuple, which is what keeps the
fix from re-prompting every consented capability; and an http lane's manifest-declared
`defaultHost` is asserted to reach both the prompt and the signature.

Reversion-controlled, seven mutations, all seven fail a named test: env dropped from the
surface, the prompt's env line removed, the execution-primitive warning removed, the
signature's extra element never appended, the residual emptied, the defaultHost line
removed, and the declares-something test un-widened. The last of those was SILENT on its
first run and its test was written in response, then the control re-run.

Refs #2483.

* enhance(#2483): correct the ADR amendment's manifest-lane premise

The amendment argued `env` needed no D5 disclosure because a manifest's `invoke`
fields never reach `resolveLanePlan`. That was true when written and #3062 retired it
22 hours after this branch's last commit: `routeReviewLane` now builds its lane map
from `mergeReviewerLanes(REVIEWER_LANES, loadRegistry({includeInstalled: true}))`, and
D1's no-translation-layer rule makes that a field-identical merge, so an overlay's
whole `invoke` reaches the resolver and executes.

The entry had named this exact trigger — "were manifest lanes ever made executable,
`env` must join the disclosed surface in that change, and nothing here will trip if it
does not." Nothing tripped. The premise is rewritten to current truth rather than
annotated, because an ADR is read in fragments and a superseded paragraph left standing
reads as live reasoning to the next author; a one-line dated tombstone points at git for
the withdrawn text.

The rewritten entry records four things the first draft could not: that the enumeration
itself was the defect (`env` was the ninth unbound `invoke` field, and `defaultHost` and
`path` are egress-relevant on their own), that the residual is what closes the class,
that D4.5's byte-identical-signature property is preserved by appending the residual only
when a lane declares something beyond the eight bound fields, and that consent — not
shape validation — is the boundary, since no honest env denylist can exclude `PATH`.

It also closes the internal inconsistency the previous entry could only record. This ADR,
`CONTEXT.md`, `gsd-core/workflows/review.md` and `resolveLanePlan`'s own header all said
overlay lanes reach the resolver while the runtime said otherwise; #3062 resolved that in
the documents' favour, which is what makes the disclosure mandatory rather than defensive.

Refs #2483.

* enhance(#2483): record in the manifest reference that invoke fields are consent-bound

`docs/reference/capability-manifest.md` is the field table ADR-2782 points capability
authors at, and it described `invoke` purely as a schema. A third-party author reading it
could not learn that everything they declare there is shown to the user at install and
bound to the consent signature — which is exactly what they need to know now that an
overlay reviewer lane executes (#2927/#3062).

States the two things the schema alone cannot: that `env` and `defaultHost` are named in
the consent prompt and the rest is covered by a residual, so any change to a declared
`invoke` field forces re-consent; and that `env`'s validation is a portability policy
rather than a safety boundary, since `PATH` is a complete execution primitive and cannot
be refused. Names that are execution primitives are highlighted in the prompt instead.

Refs #2483.

* enhance(#2483): add a Security changeset for the reviewer-lane disclosure

The existing fragment describes the enhancement this PR was opened for and stays as it
is. The disclosure fix is a separate user-visible change of a different type: a
capability declaring `invoke.env` or `invoke.defaultHost` will ask for consent once
more, and users are entitled to read why in the changelog rather than discover it as an
unexplained prompt.

Type is `Security` rather than `Changed` because the entry describes a closed
code-execution disclosure gap, not a behaviour adjustment.

Refs #2483.

* enhance(#2483): correct this round's own claim about who gets re-prompted

Self-found while auditing the round's claims before publishing them. The changeset and
the ADR entry both stated that a capability declaring `invoke.env` or `defaultHost`
"will ask for consent once more". That is wrong, and it overstated the cost of the fix
in the one direction a maintainer would have had to take on trust.

A code change to `disclosureSignature` re-prompts nobody. `hasProjectConsent` matches on
the recomputed bundle `contentHash` — the signature has not been the security binding
since #1459 CB-1/CB-2 — and the upgrade path's `executableSetChanged(old, new)` compares
two disclosures both computed by the CURRENT code, so widening the signature moves both
sides of that comparison equally. First-party capabilities never reach the path at all:
the install flow blocks a first-party id before trust evaluation.

What the widening actually buys is forward-looking, and is the real argument for it: an
upgrade whose manifest edits a declared `invoke` field now registers as an
executable-surface change and re-consents, where before it could change what the lane
runs in silence.

Also measured and recorded, because the D4.5 property was stated more strongly than it
deserved: of the twelve first-party reviewer capabilities, ZERO are in the
byte-identical-signature class — every real lane declares at least `effortChannel`. The
property is a guarantee about minimal lanes, not a description of the fleet, and the ADR
now says so.

Refs #2483.

* enhance(#2483): sign and disclose the probe binary and the lane's outer fields

Found by this round's own adversarial review, and it is the same defect one level out:
the `invoke` residual cannot reach the lane body's OUTER fields, and `probeLane` SPAWNS
`probe.binary` with `--help` before dispatch (`review-lane-runner.cts`, the
`command-exists`/`command-capability` arms). An overlay naming an arbitrary probe binary
therefore executes it — unsigned and undisclosed, exactly as `invoke.env` was, and
reachable on the same #3062 path.

The lane element now carries a second residual over the outer fields, and the probe
binary is shown in the consent prompt when it differs from the dispatch binary — it is a
program that runs, and the user is entitled to see it.

TWO fields stay excluded, and that is a decision rather than an omission:
`reviewsSection` and `timeoutFloorMs` are ADR-2782's cosmetic carve-outs (matrix
A10/A13), where re-consenting would present a prompt carrying no security information.
A test pins that they remain excluded, so a later widening cannot quietly reverse D4.5
while claiming to complete this fix.

Also corrects a miscount introduced by the previous commit: the source comment said the
enumeration had fallen behind by "seven fields" and omitted `fallbackModel`, while
asserting `env` was the ninth. `resolveLanePlan` reads twelve `inv.*` fields and four
were bound, so the number is eight. The comment now states the derivation rather than
just the total.

Reversion-controlled: emptying the outer residual fails "repointing the probe binary must
force re-consent"; removing the render line fails its own named assertion.

Refs #2483.

* enhance(#2483): refuse execution-primitive env names as defence in depth

Adopts the review's B5 after this round's own adversarial pass refuted my reason for
declining it. I had argued a denylist was worthless because `PATH` can never be refused.
That was wrong on the facts: no shipped reviewer manifest declares `PATH`, so it can be
refused, and it is the most complete primitive in the set — repoint it at a directory
holding a fake binary and the declared `invoke.binary` is irrelevant. A list that cannot
be exhaustive can still close the highest-confidence, lowest-legitimacy routes.

So the validator now rejects `PATH`, `NODE_OPTIONS`, `LD_PRELOAD`, `DYLD_INSERT_LIBRARIES`,
`BASH_ENV`, `PYTHONPATH`, `PERL5OPT`, `RUBYOPT`, `GIT_SSH_COMMAND`, `JAVA_TOOL_OPTIONS`
and their siblings on a reviewer lane. A lane needing a specific executable declares an
absolute `invoke.binary` instead of reshaping the child's environment.

The comment states plainly that this is defence in depth and NOT the boundary — the
boundary is install-time consent, which discloses every declared pair and binds it to the
signature, so an unlisted name is still SEEN before it runs. That framing is load-bearing:
a future reader who mistakes the denylist for the control will under-invest in the one
that is, which is the failure mode I was trying to avoid by declining it outright.

Two tests: the rejection itself across ten names, and a guard asserting no shipped
reviewer capability declares a denied key — so if the list ever outgrows its evidence,
that surfaces as a decision rather than a silent removal.

Refs #2483.

* enhance(#2483): fix two stale D5 enumerations elsewhere in the ADR

The previous commit rewrote the amendment's premise but swept only the amendment. Two
normative passages earlier in the same ADR still enumerated the old closed field list and
now contradicted it: the `executableSetChanged` trigger list, and the split-binding note
asserting the seven manifest-derived fields were "everything that is SHA-pinned".

That is the failure the rewrite-don't-annotate rule exists to prevent, one section over —
an ADR is read in fragments, and a fragment carries no supersession marker, so a reader
landing on either passage would have taken the superseded enumeration as current.

Both now name the residual as the mechanism rather than restating a list, which is also
what stops them going stale the next time the vocabulary widens.

Found by this round's adversarial review, which grepped the whole document rather than
the section under edit.

Refs #2483.

* enhance(#2483): stop the probe disclosure claiming a spawn that does not happen

The probe line added one commit ago rendered "probes by running: <binary> --help" for
every lane. That is false for `kind: "command-exists"`, which only calls `hasBinary` — a
PATH/filesystem scan that starts no process. Only `command-capability` spawns.

A false statement in a consent prompt is worse than a missing one: the prompt is the
surface a user is asked to trust, and this one overstated what a lane does. Worse, the
test I wrote to prove the fix used `command-exists` — the kind that does NOT spawn — so
it pinned the wrong claim and would have kept the error green forever.

The surface now carries `probeKind` and the two kinds render differently: a spawn is
described as a spawn, a presence check as a presence check. The test exercises both, and
asserts the `command-exists` path never emits the spawn wording.

Also corrects the field-count parenthetical to state its derivation unambiguously —
`resolveLanePlan` reads thirteen `inv.*` fields including `env` (twelve before this PR),
four were bound, so eight were unbound before `env` and nine including it. The bare
"twelve" was true only of the pre-PR tree and read as a claim about the current one.

And retires two comments that argued AGAINST the validator denylist this round then
shipped. Leaving them would have handed the next reader the reasoning for removing it.

Reversion-controlled: conflating the two probe kinds fails a named test.

Refs #2483.

* enhance(#2483): match the reviewer-lane env denylist case-insensitively

The denylist added one commit ago compared exact case, so `Path`, `path`, `node_options`
and `Node_Options` all passed it. Windows environment lookup is case-insensitive, so
those reach the child as `PATH` and `NODE_OPTIONS` — the exact inputs the list names.

An exactly-cased denylist is worse than none: it reads as a control while admitting the
input it was written to refuse, and the next reader has no reason to doubt it. Members
are stored uppercase and the key is folded before lookup; the name grammar already
constrains keys to ASCII, so a plain fold is sufficient.

Reversion-controlled: restoring the exact-case compare fails `envDenylistIsCaseInsensitive`
on `Path`.

Refs #2483.

* enhance(#2483): correct the docs that still described the denylist as absent

Both the ADR and the manifest reference still said `env` carries no denylist and that
`PATH` "can never be refused" — written when that was this round's position, and left
standing after the round reversed it. A reader landing on either passage would have taken
the superseded argument as current, which is precisely the failure the rewrite-don't-
annotate rule exists to prevent.

Both now describe the denylist, name `PATH`'s inclusion and the case-insensitive match,
and keep the limit explicit: the list cannot be complete against an arbitrary child and
disclosure runs before validation, so consent remains the boundary.

The ADR's byte-identical-signature claim is also corrected rather than softened. With the
outer residual in place, a lane producing no residual is one the validator rejects — it
declares no `flags`, `probe`, `emptyOutput`, `evidenceClass`, `requiresBinaries` or
`promptBudgetKey`. So the property is about the ENCODING, not a claim that any real
signature is unchanged, and it is not the argument for the change being safe. That
argument is that consent binds to the bundle contentHash and no existing consent is
invalidated at all.

Refs #2483.

* test(#2483): cover the three new lane disclosure fields in the injection-safety parity guard

The PARITY test in section N exists to catch a renderer field that skips
`renderValueForPrompt` (#3248). Its payload manifest is hand-maintained, so it
covers the fields that existed when it was written — slug, binary, args,
hostConfigKey, handler — and none of the fields this PR adds.

This PR renders three further manifest-supplied values into consent-prompt
lines: `invoke.env` (keys and values), `invoke.defaultHost` and `probe.binary`.
The gap was silent rather than theoretical: with the lane env line reverted to
the pre-#3248 raw form, the whole 948-test lane/capability/trust-disclosure
suite stayed green.

Two manifests, because the shapes render disjoint lines — `defaultHost` only on
the openai-http branch, `env`/`probe` only where declared, and the probe line
only when the probe binary differs from the dispatch binary.

Non-vacuity is asserted on the typed disclosure object and on structural line
counts, not by substring-matching rendered prose: CONTRIBUTING.md forbids raw
text matching on test output, and this section's own header promises structural
assertions only, so a prose match here would have made that promise false.

Negative-controlled three ways against the merged tree, each producing exactly
one named failure: env rendered raw, defaultHost rendered raw, probe binary
rendered raw.

* docs(#2483): extend the #3248 render-site comment to the fields this PR adds

The comment enumerates every manifest-supplied value that must pass through
`renderValueForPrompt`, and it stopped at `handler` — the reviewer-lane fields
that existed when #3248 landed. This PR renders three more (`defaultHost`, the
probe binary, and the env keys and values), so the list understated its own
contract in the one place a future author would check before adding a fourth.

A comment enumerating a closed set is a set that can silently fall behind the
code it describes; the parity test added alongside is what makes the omission
fail loudly rather than read as deliberate.

3f6b063fbb chore(#2799): invoke_reviewers and write_reviews iterate declared lanes (#2861)
* chore(#2799): resolve reviewer lanes into executable invocation plans

Phase 5b of ADR-2782. Adds the resolver and runner that let invoke_reviewers
iterate declared lanes instead of hand-authored per-CLI bash.

Five additive descriptor amendments, each forced by a lane that ships today:
- LaneHandler gains 'opencode' — the lane rebuilds its review from assistant
  text parts of a --format json stream; a plain stdout copy re-breaks #1936.
- modelConfigKey — antigravity's key is review.models.agy, not .antigravity,
  so resolving by slug silently dropped a configured model.
- defaultHost/fallbackModel — Phase 4 federated every *_host with a default of
  empty string; the real fallback only existed in the bash.
- args becomes an argv template with a closed four-placeholder vocabulary.
  Positional splicing produced 'codex --model M -o F exec --ephemeral', which
  is not a valid invocation: codex injects in the middle, twice.
- kimi-code lane, with the bounded command-capability probe (needle
  --output-format) that tells Kimi Code from the legacy python kimi-cli.

Parity gate re-pointed: the workflow-text families it scanned are the text this
phase deletes, so they are replaced by descriptor-to-registry parity plus an
anti-parity check that no bespoke leg returns.

jq, curl and external timeout/gtimeout all drop out of the review path.

Refs #2782

* chore(#2799): add review-lane query surface and widen the manifest vocabulary

Adds the gsd-tools 'review-lane' route (plan/invoke/sections) the workflow
loops over, projects all twelve lanes into their capability manifests, and
widens capability-validator for the amendments.

opencode admitted to VALID_LANE_HANDLERS under the second arm of the enum's
own admission rule: one lane, justified by a documented upstream defect data
cannot express (#1936 — the agent can end its turn with zero output tokens and
--format default then drops the assistant text entirely).

Two bugs caught by an end-to-end stub run and fixed here:
- loadConfigResolved returns a provenance wrapper, not the config; using it
  directly resolved every key to undefined, which reads as 'nothing
  configured' and silently dropped every model override.
- hasBinary used shell:true with an args array (Node 26 DEP0190). Replaced
  with a PATH scan that spawns nothing at all.

Refs #2782

* chore(#2799): iterate declared lanes in invoke_reviewers and write_reviews

Replaces the eleven hand-authored per-CLI bash legs with a loop over resolved
lanes, and renders REVIEWS.md sections from each lane's declared
reviewsSection instead of thirteen hardcoded headings. review.md drops from
1104 lines to 507 (61KB to 28.7KB).

Parity gate re-pointed, as agreed: the leg-marker and section-heading families
scanned exactly the text this phase deletes, so they are replaced by
descriptor-to-registry parity in both directions, plus an anti-parity check
that fires if a bespoke leg is ever re-added. Enum, emitting sites and the
Object.keys lock moved together.

The budget-trim helper is hoisted out of the Ollama leg: it was always
lane-agnostic, and any lane may now declare a promptBudgetKey.

Refs #2782

* feat(#2799): bind the consented egress host and re-verify it at invocation

Completes ADR-2782 D5. Rule 1 was recorded in the ADR as delivered by Phase 3
but was not implemented: ConsentRecord had no host field and nothing in the
tree bound one, so this phase's rule-4 comparison had no baseline.

ConsentRecord gains an OPTIONAL reviewerHost. Optional is the whole design:
isValidConsentRecord does not require it, so every record already on disk
stays valid and no re-consent storm fires (D4 rule 5). It is deliberately
excluded from disclosureSignature — the loader has no config resolver, so
folding a config-derived value in would make loader and lifecycle compute
different signatures for the same manifest and re-prompt forever.

Install resolves hostConfigKey (falling back to the lane's declared
defaultHost, which is what the invocation path uses) and records it.
Invocation re-resolves and blocks on mismatch rather than silently
redirecting. Absence allows: no record, or a record predating the field,
means nothing to compare — denying there would break every existing
local-model user on upgrade.

Refs #2782

* test(#2799): cover the resolver, runner and handlers; retarget the parity suites

Adds the golden invocation-plan table (one row per shipped lane, derived from
the bash legs rather than the descriptor types) plus runner coverage for the
probe, empty-output policy, the three handlers and the egress check.

Retargets the existing suites onto the new contract: descriptor-to-registry
parity, the anti-parity check, the opencode handler, and the twelfth lane.

Two corrections found by running them:
- modelConfigKey was required; that breaks D4 rule 2, since a reviewer
  manifest authored before this phase would fail validation on upgrade. It is
  optional, read as null when absent.
- the antigravity non-zero-exit test pre-seeded the transcript, which asserted
  that a STALE entry leaks through — the exact bug the watermark prevents. The
  spawn now appends, as the real tool does.

Refs #2782

* fix(#2799): restore agy --add-dir and the self-report prompt in the handler

Retargeting the three legacy reviewer suites off the deleted bash surfaced two
real regressions in the port, both #2176:

- --add-dir was dropped. Without it agy's permission context never receives the
  cwd repo, so the agent anchors on its own scratch dir and reviews the plan
  text in isolation — the exact failure the Review Instructions forbid. It is
  capability-probed, because an older agy rejects the unknown flag outright and
  a lane that fails to start is worse than one running on the prompt anchor.
- the prompt lost the clause mandating a REVIEWED-WITHOUT-REPO-ACCESS
  self-report, which is what makes a blind review distinguishable from a
  grounded one. antigravity now builds its own prompt variant.

Also ports the #2073 mode-2 cli.log diagnostic, which was dropped: a pinned
model that 404s exits 0 with empty stdout AND an empty transcript, so agy's own
log is the only evidence that anything failed.

The three suites now assert against the plan and the handler instead of
matching fence text, so they no longer need allow-test-rule exemptions.

Refs #2782

* docs(#2799): document the declared lanes, the new flag, and dropped prerequisites

COMMANDS.md gains --kimi-code and replaces the jq-prerequisite paragraph,
which is now false: no lane requires jq, curl or an external timeout. Adds the
changed-egress-destination behavior, since a blocked lane is something a user
can hit.

CONFIGURATION.md records that the model config key is declared per lane rather
than derived from the flag — antigravity's is review.models.agy — and adds
review.models.kimi-code.

reviewer-instances.md now routes an instance through its lane's single
invocation seam instead of a copied per-adapter bash block, which is what lets
a cross-cutting fix reach instances for free. That required implementing the
--model/--agent/--as flags it documents; --model re-resolves through the lane's
argv template rather than splicing, so the flag lands where the lane declares
it rather than ahead of a subcommand.

CONTEXT.md glossary gains both new modules.

Refs #2782

* chore(#2799): drop the stale emitted-drift acknowledgment

The only entry was #2797's, acknowledging COMMENT-ONLY GROWTH in review.md.
That file now shrinks by ~32KB and every emitted hash that moved is
attributable to this diff, so the ack no longer explains anything. Removing
the last entry means removing the file: its presence is the alarm, and an
empty one signals nothing.

Verified by deleting it and re-running the attribution and provenance gates
plus lint:ci — all green without it.

Refs #2782

* docs(#2799): record the Phase 5b vocabulary widenings in ADR-2782

Five additive amendments, each forced by a lane that ships today, plus two
corrections the phase had to make rather than work around:

- D5 rule 1 was recorded as delivered by Phase 3 and was not implemented, so
  this phase's rule-4 comparison had no baseline. Recorded because an ADR
  asserting a rule was delivered is exactly what stops a later phase checking.
- The DEFECT.GENERATIVE-FIX gate is re-pointed: its workflow-text families
  scanned the text this phase deletes.

Also records that D7's 'skip the probe where no bounding mechanism exists'
carve-out is obsolete — in practice it meant the Antigravity lane ran unbounded
on every stock macOS host, which ships neither timeout nor gtimeout.

Refs #2782

* fix(#2799): close four defects found by adversarial review

Two confirmed bugs, both reproduced before fixing:

- resolveLanePlan was not total. An openai-http lane with a missing or
  non-object invoke dereferenced inv.hostConfigKey and threw, contradicting
  the module's own documented contract; the spawn branch guarded correctly and
  the http branch did not. The CLI seam resolves every selected lane in one
  map, so one malformed overlay manifest would have aborted the whole review
  rather than dropping its own lane. Guarded, plus a per-lane try/catch at the
  seam so a throw can never take down siblings.
- A reviewer-instance model was silently dropped for any lane declaring
  modelConfigKey null (cursor, qwen, coderabbit). reviewer_instances validates
  that cli is a known slug but never that the slug accepts a model, so a user
  could configure one, get a clean run, and never learn a different model
  reviewed their plan. Now warns explicitly.

Two hardening fixes:

- The slug is concatenated into artifact paths, so LANE_SLUG_RE is enforced in
  the resolver rather than inherited from a validator that does not run on this
  path — the module documents itself as the overlay-manifest trust boundary, so
  it should not depend on someone else having checked.
- normalizeHost mangled a scheme-less value: new URL('localhost:11434') parses
  with an empty hostname, so it became 'localhost://11434' and was compared and
  requested as if real. An empty hostname now means not-a-URL.

Also documents the one gap that cannot be closed here: the antigravity
watermark is keyed by workspace, so two concurrent reviews of the same repo
share a transcript. agy exposes no per-invocation id to filter on, so the
handler now states which half of its never-stale guarantee actually holds.

Refs #2782

* test(#2799): retarget the remaining eight review.md-asserting suites

The remote runner found 37 failures the local sweep missed (it hit the shell's
two-minute cap before reaching these). All eight extract per-CLI bash from
review.md that this phase deletes; each protects a real invariant, so each is
retargeted onto the plan, the runner or the handler rather than removed.

Three real defects surfaced by doing so:

- effort args never reached ANY lane. model-resolver.cjs exports no
  resolveExecution, so effortFor silently returned [] every time. Restored by
  calling the same bounded resolve-execution query the bash legs used — and
  NOT with --raw, which prints the resolved effort rather than the picked
  field, so claude got 'low' instead of '--effort low'.
- the timeout guidance lost 'a silent empty output is a timeout kill, not a
  crash' — the operator note that exists because of the Codex 0xc0000142
  misdiagnosis. Restored.
- the opencode handler dropped EMPTY assistant text parts. The shipped jq was
  , and  only substitutes for false/null — an empty
  string is truthy in jq and contributed a blank line. Found by a property
  test shrinking to ['', ''].

The opencode property suite no longer spawns jq at all, which deletes the
#2099 hang mechanism it was architected around rather than mitigating it.

Refs #2782

* fix(#2799): register the two new generated modules, and untrack them

The remote runner caught build output committed to git. Both new modules
compile from src/*.cts into gsd-core/bin/lib/*.cjs, and every sibling generated
that way is gitignored and eslint-ignored (ADR-457) - including Phase 1's own
review-lane-descriptor.cjs. Mine were neither, so repo-invariants' "each
bin/lib/*.cjs is linted xor ignored according to migration state" failed.

Registered both in .gitignore and eslint.config.mjs alongside the Phase 1
module, and dropped them from the index. Nothing about the shipped behaviour
changes; the artifacts are rebuilt by build:lib.

This is the new-.cts-module registration ripple, and it is the one part of it I
had not completed - the CONTEXT.md glossary and the inventory manifest were
already done.

6a9babda69 chore(#2798): declare the eleven reviewer lanes as manifest data (#2837)
* chore(#2798): declare the eleven reviewer lanes as manifest data

Phase 5a of epic #2782, delivering ADR-2782 D9 (roster half) and D3.

- Five reviewers GSD never installs into become lane-only role:reviewer
  capabilities with no runtime body, no runtimeCompat and no install surface:
  gemini, coderabbit, ollama, lm-studio, llama-cpp. Before this they had no
  descriptor at all and lived as a hardcoded NON_RUNTIME_REVIEWER_SLUGS tail,
  which is now deleted outright.
- The six hosts that are ALSO reviewers gain a reviewer body alongside their
  runtime body. Their runtime bodies are byte-identical to next -- verified per
  capability against the git blob, not asserted -- so no install behaviour moves.
- KNOWN_REVIEWER_SLUGS derives from declared bodies via an exported
  deriveReviewerSlugs(registry). hostBehaviors.reviewerCli survives as a derived
  legacy alias for one release; where a capability carries both, the body wins
  and the slug appears once. Alias removal is Phase 7 (#2801).

THE KEYSTONE: the roster is the SAME ELEVEN SLUGS as before -- antigravity,
claude, coderabbit, codex, cursor, gemini, llama_cpp, lm_studio, ollama,
opencode, qwen. This phase changes HOW the roster is derived, not WHO is in it,
and the test asserts that literal list rather than a count.

kimi-code is deliberately NOT declared here. It is net-new with no
invoke_reviewers leg, so declaring it now would make it selectable but not
invocable -- present in --all, selected, emitting an empty section for the whole
5a-to-5b window -- and would break Phase 1's parity assertion. It lands in 5b
alongside the iteration that can run it. Legacy kimi (the Python CLI) is not a
reviewer at all and gains nothing.

The highest-value test is declaredManifestLanesMatchThePhase1Descriptor: it
deep-compares all eleven declared bodies against REVIEWER_LANES field-by-field,
including probe and invoke sub-fields. All eleven are byte-identical, key order
included. The epic's premise is that the manifest and the core descriptor
describe the same lane with NO translation layer, and Phase 2's review already
caught one divergence that every other test missed.

Two ADR corrections folded in, as Phases 1-3 each did:

1. PHASE ORDER. The ADR runs Phase 4 (federated config) before 5a and #2798
   claims a dependency on 4. That is inverted and makes Phase 4 unsatisfiable:
   D9 assigns review.<host>_host to lane capabilities that do not exist until
   THIS phase creates them, and a federated config slice must live inside
   capabilities/<id>/capability.json. Real graph: Phase 2 -> 5a -> 4.
2. #2798's INVENTORY acceptance item is vacuous. The inventory catalogs
   bin/lib/*.cjs modules, not capability directories -- antigravity, opencode
   and qwen appear zero times in it -- and gen-inventory-manifest --check passes
   with the five new dirs and no edit.

Also corrected a stale line in Phase 2's own ADR amendment: it recorded the slug
pattern as /^[a-z][a-z0-9_-]*$/, but Phase 2's security review widened the
shipped pattern to /^[a-z0-9][a-z0-9_-]*$/ to match Phase 1's exported
LANE_SLUG_RE. The prose had not followed the code.

Closes #2798

* fix(#2798): catalogue reviewer capabilities in the generated matrix

The capability matrix rendered exactly two tables, feature and runtime, via
renderTable(caps, role) filtering on c.role === role. ADR-2782 D3 added a THIRD
role, so every role:"reviewer" capability was silently dropped from the
first-party catalogue.

The drift guard did not catch it, and could not: --check compares generated
output against the committed file, and both omitted the five lanes identically,
so it reported "up to date" while five shipped capabilities were invisible in
the one document that is supposed to list what ships. A guard blind to an entire
role is not guarding.

This phase is what exposed it -- it ships the first role:"reviewer"
capabilities -- so it is fixed here rather than deferred (CLAUDE.md: a defect
found while working is fixed in the current change, which overrides
one-concern-per-PR).

Verified red-before-green: with a lane row deleted from the matrix, --check now
exits 1; restored, it exits 0. Before this fix the lanes were absent entirely, so
there was nothing for the guard to compare.

Phase 6 (#2800) still owns enriching the matrix with lane-specific detail
(slug/flag/transport columns) and the locale parity gate. This is the narrower
fix: the capabilities APPEAR at all.

* fix(#2798): close two hardening gaps and record three limits durably

Isolated security review (5 targets, no blockers) reproduced two gaps in the new
deriveReviewerSlugs. Both are unreachable through the checked-in registry -- it is
generated, JSON-sourced and code-reviewed -- but the function is EXPORTED for
reuse and carries no other validation, so it must not depend on its caller.

- A whitespace-only slug passed the length>0 test verbatim and occupied a roster
  entry it could never match. Slugs are now trimmed before the emptiness test. A
  blank body correctly falls through to the legacy alias rather than DROPPING the
  lane, which would have been worse than the blank slug.
- KNOWN_REVIEWER_SLUGS is computed at require() time, so an uncaught throw there
  breaks import for EVERY consumer rather than degrading selection. It is now
  guarded, yielding an empty roster on a malformed registry. That is a visible
  degradation, not a silent one: under D4 an explicitly requested reviewer that
  is unavailable is an ERROR, so /gsd:review --claude against an empty roster
  fails loudly. This also removes an asymmetry -- the sibling capability-trust
  module documents its collectors as TOTAL and wraps them for exactly this reason.

Also records three findings that previously existed ONLY in squash-merged PR
bodies, which is not a durable record:

- ADR-2782 D5 gains an implementation note explaining why the resolved host is
  deliberately EXCLUDED from the disclosure signature. Rule 1 says consent binds
  the resolved host; the loader has no config resolver, so folding it in would
  make the loader and lifecycle compute different signatures for one manifest and
  re-prompt forever. The binding is split: signature covers the SHA-pinned
  manifest fields, the consent record stores the resolved host, and Phase 5b
  re-resolves at invocation -- which is where rule 4 already puts the check. A
  reader comparing rule 1 to the code would otherwise conclude it is unimplemented.
- CONTEXT.md's capability-trust entry still described THREE executable surfaces.
  Phase 3 added the fourth and made that false; corrected here, since it is drift
  this epic introduced rather than Phase 6's new-glossary-term work.
- stableJson documents the NaN/Infinity/undefined -> null signature collision and
  why it is unreachable (JSON grammar has no such literal, so JSON.parse throws
  first). Reachability rests entirely on the ingest path staying JSON.parse-only,
  so the note lives where someone would break it.

46e84d5e39 chore(#2795): reviewer manifest body + registry harvest, validation, forward-compat (#2823)
* chore(#2795): reviewer manifest body + registry harvest, validation, forward-compat

Phase 2 of epic #2782 under ADR-2782. Delivers D1, D2, D3, D7, D8 and the four
Phase-1 vocabulary amendments (A1-A4).

- VALID_ROLES gains "reviewer"; the reviewer body is admissible on role:runtime
  (a host that is also a reviewer keeps one manifest) and on the new
  role:reviewer (a lane that is not an install target). A reviewer body on
  role:feature is an error: declaring one is an assertion of lane-ness.
- validateReviewerBody + validateLaneProbe + validateLaneInvoke: nine closed
  enums, a transport discriminator selecting mutually-exclusive invoke
  sub-shapes, bounded probes (D7), and outputArg required-iff outputChannel is
  file-arg and forbidden otherwise.
- Absent-safe (D4.1): only `undefined` is absent. null/{}/[]/false/0 are
  malformed assertions and error. 39 of 39 shipped capabilities depend on this.
- collectReviewerWarnings: an unknown field inside the body warns, never errors,
  so a forward-built manifest degrades visibly instead of failing the build.
- D8 uniqueness (slug / flags / reviewsSection) lives in validateCrossCapability,
  so it is enforced at build time over first-party AND at load time over the
  merged first-party union overlay set, with first-party-wins falling out of the
  loader's existing ordering rather than a new provenance check.
- Config harvest widened past the role==="feature" branch in both the generator
  and the ownership loop. The often-cited cause of the stranded reviewer config
  keys -- the runtime body forbidding feature-only fields -- is not the
  mechanism: `config` is not in FEATURE_FIELDS_FORBIDDEN_ON_RUNTIME. The cause is
  two harvest sites that never read it. Verified inert: no shipped capability
  declares config on a non-feature role, and the generated registry is unchanged.

Three ADR corrections are folded in (Phase 1 set the precedent of amending
in-phase): the misattributed config-stranding cause, D3's inverted
profile-membership claim, and the specified capability folder names for
lm_studio / llama_cpp, which would have failed the id kebab-case invariant.

Closes #2795

* chore(#2795): collapse nine enum checks into one validateEnumField helper

Standards-axis review findings, both applied:

- Duplicated Code: the enum-membership + enumerate-the-members error shape
  repeated near-verbatim at nine call sites. Routing them through one helper
  makes "the error names its valid members" structural rather than a
  convention repeated nine times, where it would drift. That property is
  load-bearing until Phase 6 ships the prose reference, because these errors
  are currently the only documentation of the vocabulary.

- Speculative Generality: the isReservedName() pre-check on every enum field
  was inert. A VALID_* set never contains __proto__/constructor/prototype, so
  membership alone already rejects them, and "must be one of: ..." is more
  actionable than "is a reserved name". The literal guards remain where they
  do real work -- the key-derived write sites in the registry generator and
  the claim() accumulator.

The reserved-name test now asserts all three reserved names are rejected via
enum membership, rather than one name via a branch that no longer exists.

* fix(#2795): align lane slug grammar with Phase 1 and wire the load-time diagnostic channel

Spec-axis review findings, both applied.

(1) The slug grammar had diverged from Phase 1's core descriptor. Phase 1 exports
LANE_SLUG_RE = /^[a-z0-9][a-z0-9_-]*$/ (leading digit permitted); the manifest
validator required a leading LETTER. A slug the core descriptor accepts -- a
model-named lane such as 4o-mini -- would have been rejected by the manifest
validator, which is exactly the translation layer ADR-2782 exists to delete. It
was inert only because all eleven shipped slugs begin with a letter, so nothing
else would have caught it until a third party shipped such a lane.

The grammar cannot be reduced to one definition: Phase 1's module compiles to
gitignored build output, and capability-validator.cjs is a committed plain .cjs
that must load on a fresh worktree before build:lib has ever run. That makes this
the repo's DEFECT.GENERATIVE-FIX class, so the duplication now carries a parity
assertion -- laneSlugGrammarMatchesPhase1Descriptor -- which compares both the
source grammar and the accept/reject verdict for a shared input set, and fails if
the two ever drift again.

(2) collectReviewerWarnings had exactly one caller: the build-time generator,
which only ever sees first-party in-repo manifests. The real third-party overlay
loader never called it and ValidatorModule did not declare it, so ADR-2782 D4.3
-- an unknown field inside a reviewer body is ignored WITH A WARNING -- surfaced
nowhere at runtime, which is precisely the case D4.3 exists for.

loadRegistry now collects those diagnostics on the accept path, behind a
typeof-guard (an older built validator without the function still loads) and a
try/catch (ADR-1244 D2's never-crash contract outranks a diagnostic). They land
in a NEW OverlayMeta.diagnostics field rather than OverlayMeta.warnings, because
warnings records capabilities that were SKIPPED and a consumer treating every
entry as inactive would mislabel a working lane.

Covered end-to-end by overlayLaneWithUnknownFieldIsAcceptedAndDiagnosed, which
drives a real global-scope overlay through loadRegistry and asserts the lane is
accepted, produces no skip warning, and yields a diagnostic naming the field.

* fix(#2795): make the reviewer validators honour their documented totality contract

Isolated adversarial review finding (MAJOR), reproduced by execution.

validateReviewerBody documents itself as "TOTAL: returns an array of error
strings for ANY input and never throws", and the overlay loader contracts every
validator to RETURN errors -- #1461 OVL-1 records a validator that THREW and
would have crashed every consumer of loadRegistry. The contract was false at ten
sites: JSON.stringify throws on a BigInt and on a circular structure, and every
enum/scalar rejection path interpolated the rejected value into its own rejection
message. Reading the value could throw too, before any message was built, via a
throwing getter or a Proxy get/ownKeys trap.

Not reachable through a capability.json today -- every ingestion path is a plain
JSON.parse of file text, which cannot express any of those shapes. Fixed anyway:
the contract is stated on an EXPORTED function, and a caller must not have to
re-derive today's reachability analysis to know whether it holds.

Two layers, because serialization safety alone is insufficient:
- describeValue() renders any value without throwing, so messages stay useful
  (a BigInt now reads "got: 10n" rather than degrading to a generic fallback).
- A structural try/catch around validateReviewerBody and collectReviewerWarnings
  makes the guarantee absolute rather than argued, covering read-time throws that
  fire before any message exists.

The same review found the property test guarding this contract was FALSE
CONFIDENCE, which is the more important half. fc.anything() at default
constraints emits no BigInt, no circular reference, no getter and no Proxy --
20,000 sampled draws produced zero of each -- so the test was named for a
contract its generator could not reach. Even withBigInt is insufficient under
whole-value fuzzing, because the defect needs an exotic value in a specifically
NAMED field and random key names never land on one.

The property is now field-targeted across all twelve reviewer fields, and a
companion test enumerates the shapes fast-check cannot generate at all
(BigInt, circular, throwing getter, symbol, function, null-prototype) across
scalar positions, array-element positions, and read-time traps.

Verified red-before-green: with the fix reverted both property tests fail; with
it restored all 119 pass.

8b44a0da43 chore(#2794): single-source the reviewer invocation contract + parity assertion (#2820)
* chore(#2794): single-source the reviewer invocation contract

Phase 1 of epic #2782 (ADR-2782). Introduces one core descriptor table as
the declared contract for all 11 cross-AI reviewer lanes, and the
DEFECT.GENERATIVE-FIX parity assertion the roster has never had.

The lane contract lived in three unrelated surfaces — the roster, ~640
lines of hand-authored per-CLI bash in invoke_reviewers, and the
write_reviews section headings — so cross-cutting fixes landed per-leg
(#2494 and #2605 were the same empty-output defect filed twice).

- src/review-lane-descriptor.cts: frozen table declaring per lane the
  slug, flags, probe, invoke shape, timeout floor, empty-output policy,
  REVIEWS.md section, evidence class, required binaries, prompt-budget
  key and handler. Field names track ADR-2782 D1/D2/D6/D7 verbatim so
  Phase 2 harvests the shape with no translation layer. It declares;
  it does not execute — invoke_reviewers iterates in Phase 5b.
- checkReviewerLaneParity: bidirectional parity across descriptor,
  roster, invoke_reviewers legs and write_reviews sections. Forward-only
  would miss the failure it exists to catch (#2718 added a leg, #2781
  was the drift). ADR-1517 instance headings are exempt per D8.
- Legs carry an explicit <!-- reviewer-lane: slug --> marker; five
  non-lane bold labels share the bold-then-fence shape a heuristic
  matcher would key on.
- ADR-2782 D4: an explicitly-flagged reviewer that cannot run is now an
  error in both the core module and the workflow prose that mirrors it.
  A code-only change would be unobservable — the module has no
  production caller; the workflow narrates the policy. Discovery paths
  (--all, review.default_reviewers) stay lenient.
- Fixes the qwen leg, the last one discarding stderr to /dev/null.

Two ADR-2782 D2 vocabulary widenings were forced by surveying the
shipped legs: promptChannel 'none' (CodeRabbit is fed no prompt) and
outputChannel 'file-arg' (Codex writes via -o and discards stdout,
#1698). Both are additive and closed; Phase 2 owns the validator.

Closes #2690

* fix(#2794): make the parity checker total and pin the lane slug grammar

Findings from the orthogonal review passes.

Spec axis — the module claimed its vocabulary tracked ADR-2782 D1/D2
"verbatim" while diverging in three undisclosed ways, which is the
translation layer Phase 2 was supposed to be spared:
- `transport` moves from `invoke.transport` to the LANE level, a sibling
  of `probe`/`invoke`, exactly as D1's manifest example places it. The
  nested form read better as a TS discriminated union; the union is now
  discriminated at the lane level instead, which costs nothing.
- The header and the CONTEXT.md glossary now enumerate all FOUR
  widenings (adding `outputArg` and `flags[]`), not two.

Standards axis — CLAUDE.md requires a fast-check property test for a
parser, and `checkReviewerLaneParity` parses markdown for markers and
headings. Adding one found two real defects that the hand-written
matrix missed:
- NOT TOTAL: a malformed descriptor entry threw on `lane.flags`
  iteration, contradicting the module's own "never throws" claim. Every
  field is now narrowed from `unknown` at the trust boundary and
  reported as MALFORMED_LANE / INVALID_SLUG. This matters because
  Phase 2 feeds this function third-party overlay data, and a parity
  gate that crashes is indistinguishable from one never run.
- SILENT GRAMMAR MISMATCH: LEG_MARKER_RE captures only [a-z0-9_-], so a
  slug outside that class was unmatchable — its marker could be present
  and correct and the scan would still report LEG_MARKER_MISSING
  forever. LANE_SLUG_RE now pins the grammar and a violating slug is
  reported INVALID_SLUG. A loud named violation beats a silent miss.

Generators are document-shaped, not writer-seeded (CONTRIBUTING #2371):
seeding from the module's own matchers could only produce documents
those matchers already recognize.

* fix(#2794): register the new bin/lib module in the ESLint ignore list

The remote runner caught this; lint:ci did not, because the invariant
lives in the test suite rather than the lint chain:

  tests/repo-invariants.test.cjs
  "each bin/lib/*.cjs is linted xor ignored according to migration state"
  -> tsc-generated bin/lib modules not yet added to ESLint ignore list:
     review-lane-descriptor.cjs

Adding a src/*.cts module ripples to six surfaces (.gitignore, the
ESLint ignore list, docs/INVENTORY-MANIFEST.json, the CONTEXT.md
glossary, the capability/inventory manifests, and any size baseline).
The other five were covered; this was the miss.

* docs(#2794): amend ADR-2782 D1/D2/D8 with the vocabulary Phase 1 surfaced

Building the Phase 1 descriptor table against all eleven shipped legs is
the first time every lane's contract was written in one place, and it
surfaced four cases the ADR's original survey did not cover. Amending
the design lock rather than diverging from it, so Phase 2 (#2795)
implements the manifest validator against the amended vocabulary instead
of rediscovering the gaps.

All four are additive widenings of closed enums; no decision reverses:

- D2 promptChannel gains `none` — coderabbit is fed no prompt at all, it
  reviews the working-tree diff.
- D2 outputChannel gains `file-arg` — the ADR called a file-writing lane
  a shape a real CLI *could* take; codex already is one, writing via
  -o/--output-last-message and discarding stdout (#1698).
- D2 gains `outputArg`, required iff file-arg — knowing the review lands
  in a file is useless without the argument naming it.
- D1 `flag` becomes `flags[]` and D8's uniqueness flattens across lanes —
  antigravity is selected by both --antigravity and --agy, which a
  single-valued field cannot express.

This is the same evidence path that produced the openai-http transport:
the vocabulary widens on a lane that exists, under review, never on
speculation.

7f13ee5373 enhance(#2793): ADR-2782 — reviewer lane becomes a declared capability surface (#2809)
* docs(#2793): add ADR-2782 — reviewer lane capability surface

Design lock for epic #2782. Declares a reviewer lane as capability data
rather than a core patch across three unrelated surfaces.

Key decisions:
- D2 transport discriminator (spawn | openai-http) — a survey of all
  twelve lanes found three that are HTTP endpoints with no binary, which
  invalidated the single-invoke-shape draft.
- D4 the reviewer body is optional and absent-safe at every layer.
- D5 a fourth executable-surface disclosure class covering the lane
  binary or host AND its egress payload classes.
- D6 handler is a closed first-party enum, upholding ADR-1016; the
  consequence — third-party lanes are data-only — is stated plainly.
- D7 probe kinds wider than existence, and every probe bounded.

Amends ADR-857, ADR-894, ADR-1016, ADR-1244. Also records the
D7/D8-extended-by-ADR-1244 marker on ADR-857 that ADR-1244 D8 promised
but never added.

Closes #2793

* docs(#2793): address orthogonal review findings on ADR-2782

Two blockers from the isolated adversarial pass:

- D5 disclosed the spawn binary but not its args, reopening the #1459
  bug class already fixed for MCP servers (binary python3 + args
  -c <program>). args are now disclosed and signature-bound.
- hostConfigKey resolves from .planning/config.json, which is mutable
  after consent with no integrity check, so a lane consented against
  localhost could be silently redirected to a remote host by an
  ordinary PR. The resolved host is now consent-bound and re-verified
  on the invocation path; a mismatch blocks the lane.

Majors and spec gaps:

- D4 gains an explicit-selection carve-out. Absent-safe governs
  discovery, never a lane the user named; the current selector records
  that as info, which Phase 1 now corrects.
- D4 gains a warning delivery channel.
- D6 enumerates the handler closed-enum members; a closed enum whose
  membership is left to the implementing phase is not closed.
- D6 records aider and plandex as concrete lanes the vocabulary cannot
  express, rather than claiming sufficiency it did not verify.
- D2 gains evidenceClass, requiresBinaries, promptBudgetKey for
  per-lane divergence that was only prose, and motivates the
  one-member outputChannel enum.
- reviewer.requires renamed requiresBinaries — it collided with the
  envelope requires (capability deps) at a different nesting depth.
- Antigravity two-level timeout: Context cited it then dropped it;
  now explicitly delegated to the handler.
- D9 gains a per-key ownership table, including three keys that stay
  central because they are policy across lanes, not lane properties.
- Phase table maps every decision D1-D9 to a delivering phase; D6
  handler modules and D5 invocation-time re-verification were
  previously unclaimed.
- American English per house style.
