* fix(#2914): never persist a spent emitted-drift ack on next tests/emitted-drift-ack.json held 34 spent #2834 entries merged via #2900. Every entry is scoped to the diff that introduced it (#2789), so once merged to next it is at the base by definition -- spent and inert. Its presence is still load-bearing though: each PR rewrites the paths map wholesale, making a persistent base copy a shared cell. Five of six conflicting PRs in the open queue collided on this file and nothing else. Deletes the stale document and adds a push-to-next guard asserting it stays absent. The guard is deliberately NOT wired into lint:ci -- a PR-lane check against the base is the #2768 shape #2789 exists to end. Closes #2914 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#2914): backfill changeset pr number Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2914): per-PR ack fragments instead of one shared mutable file The emitted-drift acknowledgment lived in a single tests/emitted-drift-ack.json whose paths map every PR rewrote wholesale. That is a shared mutable cell: any two PRs needing an ack edit the same lines and conflict. Five of six conflicting PRs in the open queue collided on this file and nothing else. Acks now live as per-PR fragments under tests/emitted-drift-acks/, the same shape .changeset/ already uses to solve this exact problem. Two PRs pick different filenames, so they cannot collide, and fragments lingering on next are harmless rather than toxic. The legacy file's 35 entries are MIGRATED into a fragment, not deleted. An earlier delete-only attempt failed verification twice: the ratchet lost the spec-phase.md acknowledgment from #2779 and reported a 10-byte growth with no ack. Relocating preserves every acknowledgment. The legacy single file is still READ (unioned with the fragments) because five open PRs carry it; dropping support would break all of them. A duplicate path key across sources is a hard error, never last-wins. The push-to-next guard is retargeted accordingly: it now asserts only that the legacy SHARED file never reappears on next. Fragments may persist harmlessly. Closes #2914 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com>
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.
