* feat(#3274): make reviewer-lane timeout configurable via timeoutConfigKey Add an optional `timeoutConfigKey` field to the reviewer lane descriptor, resolved in `resolveLanePlan` at invocation time and falling back to the frozen `timeoutFloorMs` when unset or invalid, in the same spirit as the existing `promptBudgetKey`/`modelConfigKey` fields. All 12 shipped lanes declare `review.timeouts.<slug>` on both surfaces (the descriptor and their capability.json manifest), validated by capability-validator.cjs. For the antigravity lane, the native `agy --print-timeout` flag — previously a second hardcoded literal (`540s`) independent of the outer cap — is now derived from the same resolved outer timeout in `antigravityArgv`, preserving the existing 60-second buffer relationship (ADR-2782 D6: the outer bound is declared data, the inner one is handler-owned). The antigravity default timeoutFloorMs stays at 600s per the maintainer's disposition; users raise it through the new config key instead. * docs(#3274): document review.timeouts.* and extract resolveTimeoutMs helper Address code-review findings on the timeoutConfigKey change: extract the inline timeout-resolution logic into a named, exported, directly-tested resolveTimeoutMs helper (matching the file's existing configString/ normalizeHost convention); document the new review.timeouts.* federated config keys in docs/CONFIGURATION.md, docs/reference/capability-manifest.md, and docs/how-to/ship-a-reviewer-lane.md; add the changeset fragment. * fix(#3274): resolve native antigravity timeout in resolveLanePlan, not the runner gsd-test caught two design mistakes in the prior commits: 1. SpawnPlan.argv is documented and tested as fully resolved by resolveLanePlan (model/effort/output/prompt already folded in) — leaving the antigravity '{{nativeTimeout}}' marker unresolved until the runner's antigravityArgv violated that contract and broke tests that read plan.argv directly (tests/antigravity-reviewer.test.cjs, tests/review-default-reviewers-workflow.test.cjs). Fix: '{{nativeTimeout}}' is now a fifth ARGV_PLACEHOLDER member, resolved by resolveLanePlan itself via the new nativeTimeoutToken() helper, exactly like the other four. antigravityArgv reverts to its pre-#3274 four-argument form. Also missed updating capabilities/antigravity/capability.json's invoke.args to match the descriptor, which broke the manifest/descriptor parity test. 2. tests/reviewer-config-federation.test.cjs enforces a deliberate, narrow invariant (#3691 narrows #2797): qwen, cursor, and coderabbit — the three lanes with neither a model flag nor a host — may own no config key beyond their own prompt-budget key. Adding review.timeouts.<slug> to all 12 lanes violated it. Fix: those three keep timeoutConfigKey: null and own no review.timeouts.* key, matching their existing modelConfigKey: null. The other 9 lanes are unaffected. * chore(#3274): backfill changeset PR number (pr:0 -> 4083) --------- Co-authored-by: sim <sim@local>
Changeset Fragments
This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.
Why
Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.
See #2975 for the full rationale.
Adding a fragment
node scripts/changeset/new.cjs \
--type Fixed \
--pr 1234 \
--body "fix the thing — explain the user-visible change in one sentence"
This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.
Format

**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.
Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.
Opting out
PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.
At release time
Promotion is automatic. The release workflow's finalize job runs:
node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty
This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.
Archived fragments
.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
