* test(#4130): failing-first regression for phase-prefixed decision IDs Add the #4130 matrix: D4-01/D12-01 across all three bullet forms, tags, discretion, wrapped lead-ins, gate-level plan/verify end-to-end rows, and parity properties (well-formed digit-prefixed ids parse to their exact id; a non-digit injected into the prefix fails loud). Update the #2347 non-D-prefix fixture from D5-NN (now a legal grammar) to DEC-NN, and graduate the representative d5-prefix corpus fixture from could-not-parse to parsed-but-uncovered. All new rows are RED against origin/next; they go green with the parser fix in the next commit. * fix(#4130): parse phase-prefixed decision IDs (D4-01) The three declaration grammars, the parse-miss guard, the #3939 join regexes, and the token evidence all anchored on the literal 'D-' (or '**D-'), so an ID carrying a digit-run phase prefix between the leading letter and the hyphen matched nothing — while the #2347 shape detector correctly called those bullets decision-shaped, collapsing the whole CONTEXT.md to could-not-parse with 0 extracted instead of a coverage verdict. Derive the extractor ID grammar from one shared DECISION_ID_SOURCE ('D[0-9]*-' + the existing alnum tail, full id captured), widen the guard/join anchors to ID_ATTEMPT_SOURCE (bare 'D-' or a digit-initial prefix run, so a typo'd 'D4x-01' fails loud while letter-initial prose like 'Deferred-until' stays none-present), and align the bare-token evidence. Both gates and the gap-checker share the parser, so all three surfaces read phase-prefixed decisions now; the gate messages name the accepted forms including the phase-prefixed one. * docs(#4130): document the phase-prefixed decision identifier form The canonical CONTEXT.md reference said decisions carry 'a sequential D-NN identifier' with no mention of the optional phase-number prefix the parser now accepts (D4-01) or the alphanumeric tail it always accepted (D-INFRA-01). Name both in the Decision identifier format section, EN and ja-JP. * chore(#4130): changeset * chore(#4130): backfill PR number in changeset --------- 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

type: Fixed

**`/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.
