Tom Boucher b431ae9f0d fix(#3898): a separator-shaped line in ## Gaps is skipped, not made an entry (#4057)
* test(#3898): a spaced-hyphen thematic break in ## Gaps is not an entry (failing first)

* fix(#3898): a separator-shaped line in ## Gaps is skipped, not made an entry

splitGapsEntriesCore's opener regex (/^(\s*)-\s/) matched a spaced
hyphen thematic break, fabricating a gap named '- -' with result
'unknown' — surfaced by audit-uat as an outstanding finding that
cannot be cleared by editing any entry, because there is no entry,
only the separator the author wrote for readability. Five shapes were
affected (- - -, -, and wider/indented variants); the unaffected ones
(---, ----, * * *, ___) were safe only by accident — the path never
matched them, not because it understood breaks.

A line whose content after the opening marker is solely hyphens and
whitespace (with at least one further hyphen) is now skipped entirely —
neither an opener nor a continuation. Deliberately option 2 from the
issue, not a full thematic-break concept: a break does not close the
Gaps list, entries after it keep parsing, and the deliberately-frozen
byte-for-byte Gaps behavior changes ONLY for documents carrying such a
separator (which previously produced a phantom). A real entry whose
truth begins with a hyphen (- truth: "-5 error budget...") is untouched
— its remainder contains non-hyphen characters.

* fix(#3898): review fold-ins — span-contiguous skip, property coverage

The skip is narrowed to where the phantom came from: a separator-shaped
line BETWEEN entries (nothing open, or it would open a top-level entry).
One landing strictly inside a live entry (indent > baseIndent) folds
back as a continuation line, so entry lines and the GapsEntrySpan agree
byte-for-byte — the span invariant and the #3805 ack writer's identity
re-verification both hold (the review traced the unconditional skip to
a match_verification_failed refusal in that corner). Adds the parser-
convention property test (arbitrary hyphen counts/indents/spacings) and
a span-contiguity pin.

* chore(#3898): changeset fragment (pr number backfilled after PR creation)

* chore(#3898): backfill changeset PR number (4057)

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.
