* test(#4355): assert test:coverage:unit:raw carries --merge-async tests/c8-merge-async-flag.test.cjs asserted the opposite based on a disproven assumption that `--reporter none` skips c8's merge phase -- it does not (Report.run() computes the merge unconditionally before consulting the reporter list). This is the failing-first assertion for the fix in the next commit. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#4355): add --merge-async to test:coverage:unit:raw c8's Report.run() computes the full coverage merge unconditionally, even with --reporter none -- it only skips the final text/json output, not the merge dispatch (verified against node_modules/c8/lib/report.js). Without --merge-async this used the synchronous _getMergedProcessCov(), loading every raw per-process V8 coverage dump into memory at once and OOM-crashing release.yml's finalize-test job (run 33997057100) with a silent exit 1 and no diagnostic ~21s after the test suite itself finished cleanly ("# fail 0"). Same class already fixed on the other three coverage scripts via #4068/#4172.

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.
