Tom Boucher 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.

Capability matrix reference

Generated file — do not edit by hand. This matrix is generated from the capability registry by scripts/gen-capability-matrix.cjs and kept honest by a drift guard (tests/capability-matrix-sync.test.cjs runs --check). Any manual edit is overwritten on the next generation run. To change a capability's declared metadata, edit the corresponding capabilities/<id>/capability.json and run node scripts/gen-capability-matrix.cjs --write.

Column definitions

Column Description
id Canonical capability identifier; unique across first- and third-party capabilities. Reserved prefixes: gsd-, gsd-core-, anthropic-.
role feature — extends what the loop does; runtime — adapts GSD to a specific AI runtime/IDE.
tier core — always active; standard — active when the runtime supports it; full — opt-in or runtime-specific.
engines.gsd Semver RANGE expressing host-version compatibility. A hard gate at install and at load. — means the capability declares no range.
extension points The loop points this capability registers hooks into (from the registry's byLoopPoint index). — means it registers none (typical for runtime capabilities, whose job is surface emission).
hook kinds Which of step, contribution, gate the capability's hooks use. — means none.
source first-party — ships with GSD Core; third-party — installed from an external source via gsd capability install.

On versions. This matrix intentionally omits a per-capability version column. First-party capabilities are versioned in lockstep with the GSD Core package (their capability.json version always equals the GSD release version), so a per-row version would simply repeat the package version and churn the committed file on every release. The stable host-compatibility signal — engines.gsd — is shown instead. A third-party capability's exact version is recorded in the per-runtime ledger (.gsd-capabilities.json) at install time.


Native (first-party) capabilities

First-party capabilities are implicitly trusted: they ship as part of the GSD Core package and are stamped with the package version at release (per ADR-1244 D6). They are not subject to the consent or integrity-pin flow applied to third-party capabilities.

Feature capabilities (role: feature) — 20

Feature capabilities extend what the loop does — contributing research, planning, execution, verification, or ship artefacts at the loop extension points.

Runtime capabilities (role: runtime) — 19

Runtime capabilities adapt GSD to a specific AI runtime or IDE — emitting skills, agents, hooks configuration, and surface files for that host. They typically register no loop hooks (their primary responsibility is surface emission), so their extension-point and hook-kind cells are —.

zcode runtime core >=1.6.0 — — first-party

Reviewer capabilities (role: reviewer) — 5

Reviewer capabilities declare a cross-AI reviewer lane — one external CLI or model endpoint /gsd:review hands a plan to (ADR-2782 D3). They are not install targets: they emit no skills, agents, hooks or surface files, so their extension-point and hook-kind cells are —. A host that is also a reviewer (Claude, Codex, Cursor, OpenCode, Qwen, Antigravity) keeps one manifest and appears under runtime above, carrying its lane alongside its runtime body; only lanes that GSD never installs into appear here.

Because a lane receives the plan text, requirements, research findings and CONTEXT.md decisions, it is a disclosed executable surface and is consent-gated at install like any other — see the trust model.

coderabbit reviewer full >=1.8.0 — — first-party
gemini reviewer full >=1.8.0 — — first-party

Third-party capabilities

This matrix is the first-party catalogue: it is generated from the committed registry and therefore lists only the capabilities that ship with GSD Core. Installed third-party capabilities are NOT written into this committed file. Once a user installs one via gsd capability install <spec> it enters the runtime registry overlay (ADR-1244 D2); the overlay-aware view of what is installed on a given machine is gsd capability list (see the gsd capability command reference), which reports first-party and installed third-party capabilities together using the same column fields described below, with source = third-party.

Column values for third-party rows

Column Value
id As declared in capability.json. Must not use reserved prefixes (gsd-, gsd-core-, anthropic-).
role feature or runtime, as declared.
tier core, standard, or full, as declared.
engines.gsd Range from capability.json; verified at install and at each load.
extension points The loop points the capability registers into, validated against the known 12 identifiers.
hook kinds step, contribution, and/or gate as declared. Disclosed in the consent summary at install.
source third-party

Community registry

Whether GSD operates or advertises a central community registry of third-party capabilities is TBD/TBA (PRD). The matrix mechanic and all manifest fields ship regardless of that decision; URL/git/npm/tarball import does not depend on a central registry.


Manifest field reference

The fields below are defined in capability.json and govern how a capability appears in this matrix. For the full schema, see ADR-1244 D1 and the capability manifest reference.

Field Required Type Purpose
version Yes semver string Capability version. The registry rejects manifests without it.
engines.gsd Recommended semver range Host-version compatibility gate. Enforced at install and load.
compatVersions No object: cap-version → gsd-range Graceful-downgrade table for sources that enumerate versions (git tags, registry, npm).
integrity No sha512-<base64> SHA-512 digest of the fetched bundle. Verified before extraction when present; mismatch aborts.
provenance No { sourceRepo, commit } Source provenance; populated in CI for first-party/curated capabilities.
