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.
