* enhance(#4095): checkpoint:decision auto-selection is opt-in via auto_select Auto-mode used to auto-select a checkpoint:decision's first <option> unconditionally, making a decision checkpoint's safety depend on option presentation order rather than an authored choice. Add an optional auto_select="<option-id>" attribute on the <task> tag: absent, auto-mode now escalates to a human exactly like gate="blocking-human" does; present, it names the option auto-mode selects; naming an id with no matching <option id> is a hard structural-validation error at plan-parse time rather than a silent fallback to the first option. gate="blocking-human" continues to win over everything, unchanged. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#4095): anchor auto_select/id attribute regexes past hyphenated decoys An isolated adversarial review of the auto_select work found that both new attribute regexes used \b as their left anchor, which is a word boundary, not a "start of attribute name" boundary. A decoy attribute ending in the same word (e.g. data-id="...") sitting before the real id="..." on the same <option> tag matched first, silently corrupting the extracted option id. Anchor on (?:^|\s) instead so only the real attribute name can match. Adds a regression test reproducing the exact decoy-attribute shape, plus a Unicode option-id test from the same review pass. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * test(#4095): register auto-select-attribute.test.cjs in the docs-guard lane lint-docs-guard-registration failed: the new test reads docs/reference/ plan-md.md but was not registered, so a future edit to that doc could silently desync from the test without the guard catching it on the PR that changed the doc. Registered alongside its direct precedents (precondition-element.test.cjs, reversibility-tagging.test.cjs), which read the same file for the same reason. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#4095): fit the decision bullet under execute-phase.md's frozen byte ceiling The remote gsd-test run caught what local checks missed: execute-phase.md carries a frozen ADR-857 Phase-6 byte ceiling (93600) with only 36 bytes of headroom before this change, and the original checkpoint:decision wording pushed it to 93772 (over the ceiling). Cascaded into failures in phase6-capstone-conformance, execute-phase-completion-reconciliation, claude-orchestration, and the compact-content drift-report test. Also caught: tests/package-legitimacy-gate.test.cjs anchors a "decision is conditional, not unconditional" safety check on the literal phrase "first option" in the decision bullet — which #4095 deliberately removes, since there is no more unconditional first-option pick. The test was asserting an assumption this change intentionally makes obsolete; re-anchored on tokens that still identify the bullet ('decision', 'auto-spawn') without weakening what the test actually verifies (the bullet must still carry a blocking-human carve-out). Also fixed a word-order mismatch between my own new test's regex and the actual doc text it was asserting against (tests/auto-select-attribute.test.cjs). Regenerated the compact-content benchmark baseline (tests/fixtures/compact-content-benchmark-baseline.json) to match the new byte counts. Emitted-Drift-Ack-Growth: gsd-executor.md — +7 bytes (49138 -> 49145), from the auto_select carve-out added to the checkpoint:decision auto-mode bullet; already trimmed once to fit the 49152 hard cap. Emitted-Drift-Ack-Growth: execute-phase.md — +12 bytes (93564 -> 93576), from the same carve-out in the orchestrator's decision bullet; kept 24 bytes under the frozen 93600 ADR-857 ceiling after two rounds of trimming for clarity vs. margin.

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.
