* enhance(#2573): stamp STATE.md with its commit and surface a commit-age freshness hint Adds a `state_head` stamp to STATE.md and derives a tri-state commit-age freshness proxy (state_commits_behind / state_commit_stale) through state.cjs's readStateHeadFreshness, surfaced on smart-entry signals and as health W024. The proxy is advisory: classify() deliberately does NOT consume it (ADR-1787 locks the classification/routing boundary — a signal, not a route). Composes with #3099 and #1882 (both merged to next after this branch): the commit-age proxy reads `state_head` while the LAST_ACTIVITY_UNPARSEABLE diagnostic reads `last_activity` — two different fields, not "two staleness signals on one field." A new regression test asserts a STATE.md carrying both an unparseable last_activity AND a valid state_head resolves each independently (diagnostic fires once; freshness reads state_head, commits_behind 0). Rebased onto next (flattened): resolved the add/add conflicts in src/smart-entry.cts (kept both the #2573 freshness import/derivation and the #3099 diagnostic import/call) and tests/smart-entry.unit.test.cjs (kept both describe blocks). Drift-ack for health.md's W024 row is unchanged (12348 B). Tests: smart-entry 62, state/state-transition/health/verify 639, all pass. * chore(#2573): allowlist health-validation test in the prompt-injection scan The scanner's `exec('` code-execution pattern matches the benign `re.exec('<phase-id>')` RegExp method calls in the phase-ID grammar tests (pre-existing: 16 such calls on next, this PR adds none). The file entered the diff-mode scan's changed-file set only because #2573's W024 state_head assertions touch it. Allowlist it alongside the other test files that carry pattern-matching content as data (same DEFECT.PROMPT-INJECTION-SCAN-COLLISION class). Scanner self-test 38/0; diff scan 14 files, 0 findings.
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
---
type: Fixed
pr: 1234
---
**`/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.
