Two code-confirmed defects in `gsd-tools phase complete` (re-verified against next; the three severe corruption paths the issue filed are superseded by the ADR-1769 Transition Module migration + #2012, so this is the confirmed remainder). 1. Milestone-end mislabel (isLastPhase). The milestone-end determination only cleared isLastPhase when a HIGHER-numbered phase existed, so completing the numerically-highest phase out of order (e.g. Phase 10 before Phase 9) stamped STATE.md `Status: Milestone complete` while a lower phase was still outstanding. Added a lower-phase check: after the existing higher-phase scans, if any earlier phase in the current milestone has an unchecked roadmap checkbox (`[ ]`), isLastPhase becomes false AND next_phase/next_phase_name point at the LOWEST outstanding lower phase — so STATE.md advances to the real gap instead of parking on the just-completed phase. A completed phase always has `[x]` (phase.complete sets it), so all-lower-complete still reports milestone-end; heading-only roadmaps (no checkboxes) retain prior behavior. The checkbox regex mirrors the sibling phasePattern's anchoring (whitespace/bold + required `:`) so unrelated checklist lines mentioning "Phase N" don't match. 2. Workstream root-fallback (no guard). cmdPhaseComplete resolves every path via planningDir(cwd); with a `workstreams/` dir present but no active workstream and no --ws, that returns root `.planning`, so phase.complete wrote STATE.md/ ROADMAP.md (and the mislabel) into the shared root other workstreams read. Added the same #1912 fail-safe guard init.progress got: refuse (asking for `--ws`/active workstream) instead of silently writing root. Resolution itself was already wired globally (resolveActiveWorkstream: --ws > GSD_WORKSTREAM > pointer, set in bin/gsd-tools.cjs), so only the refusal guard was missing. The workstream-mode detection (`listAvailableWorkstreams`) is extracted into planning-workspace.cts as the single source of truth and consumed by BOTH init.progress and phase.complete, so the two fail-safe paths cannot drift. Tests (tests/phase.test.cjs, new #2028 describe): out-of-order completion becomes `Ready to plan` with is_last_phase=false, next_phase pointing at the outstanding phase and Current Phase advancing to it (not the completed phase); all-lower- complete still reports milestone-end; workstream-mode-no-active refuses with an `--ws` hint; `--ws` completes in the workstream leaving root untouched; flat mode unaffected. Fail-first verified locally via direct gsd-tools invocation. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.
