* fix(#4220): terminate the temp-sweep ancestor walk with a fixed-point check scripts/run-tests.cjs's sweepProtectSet block walked each selected test file's ancestor directories, stopping on `cur !== runTempRoot && cur.length > 1` — a POSIX-only sentinel. path.posix.dirname('/') === '/' (length 1) correctly stops, but path.win32.dirname('C:\\') === 'C:\\' (length 3) never satisfies the length check, so the walk spun forever on Windows whenever a selected file lived outside runTempRoot (the common case). This has hung every Windows CI shard since #4207. Extract the walk into a pure, exported computeSweepProtectSet(selected, runTempRoot, dirnameImpl) helper and replace the length sentinel with a fixed-point check (stop when dirnameImpl(cur) === cur), which terminates correctly on POSIX, Windows drive roots, and UNC roots alike with no platform branch. * fix(#4220): repoint TEMP/TMP alongside TMPDIR in run-tests-temp-root test child env Node's os.tmpdir() on Windows never reads TMPDIR, only TEMP/TMP. The test's runNode child-process env override only set TMPDIR, so on a real Windows runner nested inside a run-tests invocation the child inherited the outer process's already-repointed TEMP/TMP and its mkdtempSync(os.tmpdir()) landed under the outer run's temp root instead of the test's intended `outer` directory. This was masked on gsd-test's benches and locally because Windows CI always died in the #4220 infinite loop before reaching this test. * fix(#4220): stop the ancestor walk from protecting the filesystem root itself computeSweepProtectSet added `cur` to the protect set before checking whether dirname(cur) === cur, so on the terminating iteration it protected the filesystem root (posix `/`, and analogously a win32 drive root) instead of stopping before adding it. Caught by the existing posix-parity regression assertion (`!protectSet.has('/')`) on the linux-node24 gsd-test bench. Reorder to compute the parent and check the fixed point before adding. * fix(#4220): backfill changeset pr number to 4245 --------- 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.
