* test(#3257: full-line frontmatter comments survive the parse→reconstruct pair AND a mutating state verb parseYamlRegion dropped column-0 # comments and reconstructFrontmatter rebuilt from Object.entries alone, so full-line comments were silently destroyed on every mutating STATE verb. Add failing-first regressions: 3 unit tests for the public pair (comment between keys, leading+trailing, consecutive) and an e2e test running a state verb (state update) on a commented STATE.md — the e2e exercises syncStateFrontmatter's fresh-derivedFm rebuild path, which is the actual loss site the issue is filed against. RED — fails on next; fix follows. * fix(#3257: preserve full-line frontmatter comments through parse→reconstruct AND syncStateFrontmatter Carry column-0 # comments through the frontmatter pair via a Symbol-keyed channel (FULL_LINE_COMMENTS): parseYamlRegion captures ^# lines and attaches them to the next top-level key (leading) or a trailing slot; reconstructFrontmatter re-emits them in place. The Symbol is invisible to Object.entries/keys/JSON, so every existing reader is unchanged; the channel is created only when a comment is seen, so comment-less frontmatter is byte-identical. CRITICAL (isolated review): syncStateFrontmatter rebuilds its target via buildStateFrontmatter (fresh object) + an Object.keys carry-forward, both of which skip the Symbol — so the pair-preserving channel was lost on the very STATE verbs the issue names. Export propagateCommentChannel(source, target) from frontmatter.cts and call it in syncStateFrontmatter before reconstruct, copying the channel onto derivedFm (leading filtered to keys still present so a deleted key's annotation drops with it, trailing preserved).

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.
