* test(#3849): phase allocation must skip numbers held by sibling worktrees (failing first) * fix(#3849): phase allocation counts numbers held by sibling git worktrees Both allocators (cmdPhaseAdd, cmdPhaseAddBatch) chose max+1 over numbers gathered from ONE checkout — headers, bullets (add only), on-disk dirs. Every sibling git worktree carries its own .planning/ on its own branch, so a phase minted there was invisible and the same number was allocated twice (the reported incident: two Phase 441s, one with six written plans, surfaced a day late by human memory). New shared horizon collectSiblingWorktreePhaseNums: one git worktree list --porcelain, then per sibling — phase-dir names (the cheap scan that would have caught the incident) and the WHOLE sibling ROADMAP.md headers (a row can predate its dir; milestone-scoping would be wrong — a number used under any milestone on another branch is taken). Widen, never refuse: unreadable sibling / no .planning / not a git repo / git unavailable each contribute nothing and allocation is unchanged. Reuses isSentinelPhaseId and the allocators' own patterns. Secondary (#1229 never reached batch): cmdPhaseAddBatch now also scans roadmap bullets — a bullet-only 'Phase N' row was invisible to batch allocation, exactly the condition #1229 was filed for. Also fixes the two new tests' result-key access (output.phases, not output.results). * fix(#3849): review fold-ins — subprocess band, bounded test git, linked-worktree fixture - execFileSync options now match the repo's git band (10s window, windowsHide, 4MiB maxBuffer) — a spurious 4s timeout silently reverted to the pre-fix collision. - test git helper bounded (15s) per local/no-unbounded-spawn. - new fixture: allocation FROM a linked worktree counts the main checkout — the incident's actual topology direction. - fixture-setup rmSync carries the sanctioned lint-disable (setup, not teardown; cleanup() still owns directory removal). * fix(#3849): exempt the sibling-worktree scan from the enumeration-drift guard collectSiblingWorktreePhaseNums reads a SIBLING checkout's phases dir — a different question from the cwd-scoped listMilestonePhaseDirs the guard routes everything to (which cannot see another worktree's .planning at all). Function-scoped, per ADR-3180 Decision 4(a): any other re-derivation in phase.cts is still caught. The GREEN bench caught the omission. * chore(#3849): changeset fragment (pr number backfilled after PR creation) * chore(#3849): backfill changeset PR number (4042) --------- Co-authored-by: sim <sim@local>
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.
