code-review.md states (line 144) "Skip SUMMARY/git scoping entirely when --files is provided." Tier 2 honors this via `if [ -z "$FILES_OVERRIDE" ]`, but Tier 3's #2666 SUMMARY/diff cross-check had no FILES_OVERRIDE reference at all -- reached via `elif [ -n "$DIFF_BASE" ]` whenever REVIEW_FILES was already non-empty (true under --files, since Tier 1 fills it), so it silently appended the whole phase's changed files onto an explicit user-supplied file list. --files is documented as the highest-precedence scoping tier (D-08) and is the flag Tier 3's own fail-closed path recommends when no reliable diff base is found; a user narrowing a review to two files silently got the whole phase instead, and the reviewer agent spent its budget on files nobody asked about. Gated the elif on the same condition Tier 2 already uses: elif [ -z "$FILES_OVERRIDE" ] && [ -n "$DIFF_BASE" ]; then The issue's own narrowest suggested form, reasoned through against two alternatives (wrapping the whole Tier-3 fence, or changing the stated invariant instead) -- both explicitly rejected there for good reasons concurred with after reading the surrounding code. Added tests/code-review-tier3-files-override-scoping.test.cjs, mirroring the issue's own verified reproduction methodology: extracts the Tier 1/2/3 fences VERBATIM from code-review.md (never reimplemented) and runs them against a real constructed git fixture matching the issue's own scenario exactly (5 files, a SUMMARY listing only 1). Confirms --files stays scoped to exactly the requested file, and separately confirms the #2666 cross-check still widens a genuinely partial SUMMARY scope when --files is absent (proving this is a gate, not a blanket disable). Emitted-Drift-Ack-Growth: code-review.md — #4460 gates the Tier-3 #2666 cross-check on FILES_OVERRIDE, matching Tier 2's own guard, net +453 bytes Co-Authored-By: Claude Sonnet 5 <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.
