Before it, a lane was declared across three unrelated surfaces — the roster in `src/review-reviewer-selection.cts`, ~640 lines of hand-authored per-CLI bash in the `invoke_reviewers` step of `gsd-core/workflows/review.md`, and the hardcoded section headings in `write_reviews` — so cross-cutting fixes landed per-leg (#2494 and #2605 were the same empty-output defect filed twice; #2475/#2295/#2272 are the same shape). Interface: `REVIEWER_LANES` (frozen table of the 11 shipped lanes, each declaring `slug`, `flags`, `probe`, `invoke`, `timeoutFloorMs`, `emptyOutput`, `reviewsSection`, `evidenceClass`, `requiresBinaries`, `promptBudgetKey`, `handler`), `PARITY_VIOLATION` (frozen reason enum — adding a reason is three coordinated changes: enum + emitting site + the test locking `Object.keys(...).sort()`), and `checkReviewerLaneParity({descriptor, roster, workflowText}) → {ok, violations[]}`. **The module DECLARES; it does not execute** — `invoke_reviewers` still runs hand-authored legs until Phase 5b (#2799) makes it iterate; what Phase 1 guarantees is that a leg cannot be added, removed, or renamed without the table and the `REVIEWS.md` section moving with it. Field names, **nesting**, and enum members track ADR-2782 D1/D2/D6/D7 so Phase 2 (#2795) harvests the shape into the capability manifest with no translation layer — including `transport` at the **lane level** (a sibling of `probe`/`invoke`, as D1's manifest example places it) rather than nested inside `invoke`, which would read more naturally as a TS discriminated union and is exactly the convenience Phase 2 would have to translate away. **Four** vocabulary widenings were forced by surveying the eleven shipped legs, all additive widenings of closed enums, each forced by a lane that exists today — and **ADR-2782 was amended in the same PR** (its Amendments section, 2026-07-29) rather than left diverging, so Phase 2 implements the validator against the amended vocabulary: `promptChannel: 'none'` (CodeRabbit is fed no prompt — it reviews the working-tree diff), `outputChannel: 'file-arg'` (Codex captures the review through its own `-o/--output-last-message` and discards stdout, #1698), `outputArg` (its companion — knowing the review lands in a file is useless without the argument naming the file), and `flags: string[]` where D1 shows a singular `flag` (Antigravity is selected by both `--antigravity` and `--agy`, which one field cannot express; this also widens D8's uniqueness invariant, enforced here over the flattened flag set). `LANE_SLUG_RE` (`^[a-z0-9][a-z0-9_-]*$`) pins the slug grammar because `LEG_MARKER_RE` can only capture `[a-z0-9_-]`: a slug outside that class is **unmatchable** — its marker can be present and correct and the scan still never sees it — so a violating slug is reported `INVALID_SLUG` rather than reported missing forever. A loud named violation beats a silent miss. The descriptor deliberately does **not** promise uniformity — lane divergence is real and frequently correct (three lanes are HTTP endpoints with no binary; timeout floors genuinely differ; Antigravity needs a three-layer fallback for an upstream stdout bug) — so behavior data cannot express is delegated to a named `handler` (closed first-party enum: `null` | `antigravity` | `openai-compatible`), never to conditionals inside the table. `checkReviewerLaneParity` is the `RULESET.GENERATIVE-FIX` assertion the roster has never had, and it is **bidirectional**: a forward-only check misses the failure it exists to catch (#2718 added a lane leg, #2781 was the drift that followed), so an undeclared leg fails too. Legs are identified by an explicit `` marker rather than inferred from prose shape, because five non-lane bold labels in `invoke_reviewers` share the bold-then-fence shape a heuristic would key on. Section matching is anchored at h2 with an exact ` Review` suffix and no parenthetical, so ADR-1517 reviewer-instance headings (`## OpenCode Review (opencode-deepseek)`) are exempt — ADR-2782 D8: instances are not lanes. Pure and total: no filesystem access, CRLF-insensitive, and **never throws on any input** — every field is validated before use (`MALFORMED_LANE` / `INVALID_SLUG`) rather than trusted, because Phase 2 feeds this same function manifest-derived data from third-party overlays, and a parity gate that crashes on bad input is indistinguishable from one that was never run. Empty input degrades to violations so a read failure is never mistaken for a clean bill of health. Totality, determinism (no leaked regex `lastIndex`), and the invalid-slug contract are `fast-check` property-tested with a pinned seed. Phase 6 (#2800) adds a SECOND, deliberately separate pure gate in the same module — `checkReviewerDocsParity({descriptor, docs}) → {ok, violations, skipped}` with its own frozen `DOCS_PARITY_VIOLATION` enum — answering *what is documented* rather than *what runs*, so a stale doc can never make the runtime checker look red and the seven dependents of `checkReviewerLaneParity` never move. It is the `RULESET.GENERATIVE-FIX` parity assertion this roster had always required and never had (only the Cursor lane ever carried one). Three independent arms: declared flags appear delimited (backticked or bracketed, so a bare flag in a fenced example cannot satisfy the gate) in `docs/COMMANDS.md`, `docs/FEATURES.md` and their four locale mirrors; a `Command:` signature line is held to the full roster and rejects undeclared bracketed lane flags; and the Purpose paragraph beneath it must name every declared `reviewsSection` — the arm that catches the class where a `Command:` line is updated and the line below it is not. Section titles are matched LITERALLY (`llama.cpp` would otherwise let `llamaXcpp` pass). A mirror carrying no `/gsd:review` surface is reported in `skipped`, never failed, so a partial translation is not misread as drift. Its totality is property-tested too, which is how the non-callable-`toString` coercion crash was found before it shipped. Source of truth: `src/review-lane-descriptor.cts`. Test anchors: `tests/review-lane-descriptor.test.cjs`, `tests/reviewer-docs-parity.test.cjs`. See `docs/adr/2782-reviewer-lane-capability-surface.md`. ### Reviewer Lane Invocation Module -Module owning the projection from a **declared reviewer lane** plus resolved configuration to a concrete **invocation plan** — the value a lane is actually run from (ADR-2782 Phase 5b, #2799). Pure: no filesystem, network, subprocess or clock; configuration arrives through a `configGet` seam. Interface: `resolveLanePlan({lane, configGet, runDir, repoRoot, effortArgs}) → {ok, plan} | {ok:false, reason, detail}`, `LANE_UNAVAILABLE` (frozen reason enum — a lane that will not run reports WHY, because the ambiguity between "failed" and "ran cleanly with nothing to report" is the defect class this epic closes), plus `isEmptyReview`, `normalizeHost` and `fileRefPrompt`. TOTAL — a malformed lane yields an unavailable result, never a throw, because third-party overlay manifests reach this seam. `invoke.args` is an **argv template** over a closed four-member placeholder vocabulary (`{{model}}`, `{{effort}}`, `{{output}}`, `{{prompt}}`), not a prefix: the injected pieces do not all go in the same place — `codex` injects the model after its `exec` subcommand and the output file later still, while five lanes end with a bare `-` that must stay last. Each lane's plan was derived FROM its former bash leg, and a golden table asserts all twelve; that table is the strangler-fig substitute for a parallel run. +Module owning the projection from a **declared reviewer lane** plus resolved configuration to a concrete **invocation plan** — the value a lane is actually run from (ADR-2782 Phase 5b, #2799).

The banner arm is gated on `outputTarget.kind === 'file'`, because a stdout lane's own review text would otherwise be scanned as its banner. `antigravityWatermark` now snapshots BOTH transcripts — `lines` for `transcript.jsonl`, `fullLines` for `transcript_full.jsonl` — since they are different files with different counts and one cannot offset the other. The model arm's staleness rule is deliberately looser than the review body's: a matching conv-id means the same `agy` session, whose model is this run's. Every arm is total and degrades to `unknown` — it may never fail a lane (#2295). ### Resolution Provenance Cross-seam principle (ADR-1411, epic #1411): context resolution — config loading, project-root anchoring, workstream resolution — must report its provenance, not fall open silently to defaults. A resolver anchors deterministically to the project root (one walk-up module, no dependence on an arbitrary descendant cwd), returns *what* it resolved **and** *where it came from* (`source`/`degraded`), and surfaces a diagnostic when a *configured* input resolves empty (`not configured` and `configured-but-empty` are distinguishable). The resolution-side analog of ADR-227 (input-validation shape). Target seams: Config Loader Module (`loadConfig` → `ConfigResolution { config, source, degraded }`), Project-Root Resolution Module (single nearest-`.planning/` walk-up, retiring ad-hoc resolvers like `resolvePlanningCwd`), I/O Module (`Resolution { value, configured, reason, warnings }` output envelope). A configured input resolving empty without a reason is a CI-guarded regression. **P1 (nearest-.planning/ heuristic) shipped in #1413; P2 (loadConfigResolved + agent-skills diagnostic) shipped in #1415 / closes #1366**: `loadConfigResolved` now implements the Config Loader seam target; `cmdAgentSkills` uses `findProjectRoot` + `loadConfigResolved` and emits `configured`/`reason`/`source`/`degraded` in its `--json` IR. **Corrupt is not absent (ADR-1411 amendment 2026-07-26, epic #1879 Phase 0 / #2674):** the principle above governs a resolution *miss*; input that is present but *not usable* (a `SyntaxError`, an errno such as `EACCES`/`EIO`, or a malformed structure with no exception at all) is a distinct class that must stay distinguishable from genuine absence. The defect in that class is not the fallback — ADR-227 requires malformed input to be coerced rather than propagated, and this ADR already permits a fallback — it is that the fallback is **invisible**. So every current return value is preserved and the cause is made visible by one of two mechanisms: **in-band**, where the result already carries a provenance envelope, name the cause in it (`ConfigResolution` gains a `reason`; `Resolution`'s four documented values all describe a miss, so new unusable-input values are introduced with the first adopter) and also expose it on the surface callers actually use, since a `reason` no caller reads is an unreachable field; **out-of-band**, where the read returns a bare sentinel or a plausible default it cannot extend, keep that value and emit a deduplicated `stderr` diagnostic keyed on resolved-path + errno, reusing the `_warnedUnknownConfigKeys` guard pattern. The diagnostic is unconditional — a deliberate divergence from ADR-227's never-implemented `GSD_DEBUG` opt-in, since an opt-in nobody sets is the same silence. Throwing is **not** the cluster's answer — it stays confined to ADR-227's genuinely-fatal carve-out, decided per call, never inferred from the return shape. diff --git a/docs/COMMANDS.md b/docs/COMMANDS.md index df575c905..8cf46106f 100644 --- a/docs/COMMANDS.md +++ b/docs/COMMANDS.md @@ -1614,6 +1614,8 @@ Reviewers reached through `--all` or `review.default_reviewers` behave different **Produces:** `{phase}-REVIEWS.md` — consumable by `/gsd-plan-phase --reviews` +Its frontmatter records the model each reviewer resolved to, as `models:` (the model id, or `unknown`, with a `(reasoning=)` suffix when GSD applied a reasoning effort to that lane) and `model_sources:` (how each value was determined — `pinned`, `served`, `requested`, `banner`, `transcript`, or `unknown`).
