* chore(#2143): bounded-mutation seam (withSection/withPhaseSection) + phase.cts migration — Phase 2 Phase 2 of epic #2143 (ADR-2143 §4): add a bounded-mutation primitive so a per-phase ROADMAP edit is structurally confined to that phase's own section, and migrate the phase-scoped mutation sites in `phase.cts` onto it. - `src/markdown-sectionizer.cts`: `withSection(content, target, edit, opts?)` — resolves a section via `collectSection` and applies `edit` to ONLY that section's body, re-serialising via `replaceSection`. The edit callback sees only the section body, so any regex it runs is physically confined. - `src/roadmap-parser.cts`: `withPhaseSection(content, phaseId, edit)` — resolves a phase's `### Phase N` detail-section heading via the #2121 phase-id source and delegates to `withSection`. Heading match is anchored to the heading start (a sibling phase whose title mentions the number is not hijacked) and bounds at the next ATX heading of any level (`levelBounded:false`). - `src/phase.cts`: `mutateMilestonePhase`'s plan-count and per-plan-checkbox writes now route through `withPhaseSection` — structurally retiring the #2130 / #2067 / #2080 boundary-crossing class for these sites. The phase-LIST checkbox is intentionally left milestone-slice-scoped (it lives outside any `### Phase N` detail section). Cross-phase renumbering is untouched. - Property test (fast-check): editing phase k leaves every sibling section byte-identical; regression tests for title-collision + mixed heading depth. Behaviour-preserving (verified by old-vs-new differential runs on real fixtures). Extend-never-mutate (ADR-2143 §2). Registration: CONTEXT.md + docs/INVENTORY.md export lists.

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.
