* fix(#706): skip rescueSummaryArtifacts when SUMMARY is already committed rescueSummaryArtifacts now probes `git cat-file -e HEAD:<path>` before copying a SUMMARY.md into the main checkout. When the file is already committed on the worktree branch, copying it as an untracked file causes `git merge --no-ff` to abort with "untracked working tree files would be overwritten by merge" — a permanent merge_failed cleanup-wave failure. Fail-closed on timeout: if cat-file is unreliable we skip rescue (the merge will surface the collision as it did before, which is recoverable). Adds 4 new test cases in worktree-safety.test.cjs covering: - committed SUMMARY skipped, merge succeeds (#706 regression case) - committed SUMMARY skipped even when timeout (fail-closed) - uncommitted SUMMARY still rescued (existing contract preserved) - rescue failure on ENOSPC still propagates (unchanged) Closes #706 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * chore: add changeset for #706 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#706): treat cat-file exit 128 as uncertain — skip rescue (fail-closed) The previous guard skipped rescue only when `exitCode === 0` (committed) or `timedOut`. Any other non-zero exit, including `128` (fatal git error: corrupt object store, unborn HEAD, missing repo), fell through and PROCEEDED with rescue — potentially re-creating the #706 untracked-file merge collision. Fix: rescue ONLY when `exitCode === 1` (cat-file definitively reports the object absent). All other outcomes — 0 (committed), 128 (fatal), null/SIGTERM (timeout), or any other code — are treated as "uncertain → skip rescue". Also corrects the JSDoc bullet that still referenced `git ls-files --error-unmatch` (the old mechanism); updated to `git cat-file -e HEAD:<relPath>`. Regression test added: asserts rescue is SKIPPED when cat-file returns exit 128, leaving the merge to surface the issue safely rather than silently copying an already-committed file.

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.
