Follow-up to #1919 (archive-then-remove core). Closes the remaining #1871 acceptance criteria so phase history is preserved across the full milestone lifecycle, not just at phases.clear: - #2 src/milestone.cts + src/phases-command-router.cts: extract shared archivePhaseDirectories() helper; add cmdPhasesArchive (the previously half-wired phases.archive alias now routes instead of erroring Unknown). - #4 gsd-tools.cjs + src/milestone.cts: milestone complete archives phase dirs by default (--no-archive-phases opts out; --archive-phases is now a harmless no-op). complete-milestone.md updated to drop the redundant manual Yes/Skip archive prompt. - #3 gsd-core/workflows/new-milestone.md: §6 stages the archive move + source removal (git add .planning/milestones/ .planning/phases/) in the same commit as the milestone start, so the archive lands atomically — no orphaned uncommitted deletions, no un-archived dirs inherited. - docs/CLI-TOOLS.md (+ ja/zh/ko/pt) + help/modes/full.md: flag accuracy. - tests: phases archive command (#2) + milestone complete default archive / --no-archive-phases opt-out (#4). Goldens + workflow size baseline refreshed. Closes #1871
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.
