* fix(#2232): cap phase-token continuation segments at exactly 2 digits (all sites) A phase whose slug's first word is a ≥2-digit number (dir 14-2026-photos-performance, roadmap phase "2026 Photos & Performance" → slug 2026-photos-…) had its phase token over-collected as "14-2026" instead of "14", so every phase-locating verb (init.plan-phase, init.execute-phase, phase-plan-index, state.planned-phase, roadmap.annotate-dependencies) resolved phase_dir=null / plan_count=0 while the directory existed. This is the residual case #2043 explicitly scoped out: its ≥2-digit continuation gate (\d{2,}) distinguishes single-digit slug words but not multi-digit ones (years, counts). The structural distinguisher: getPhaseDirFromPhaseId writes sub-phase and plan continuation segments zero-padded to EXACTLY 2 digits, so a genuine continuation's digit run is exactly 2 — \d{2}(?!\d). The (?!\d) guard caps the run without anchoring what follows, so each call site keeps its own trailing grammar (letter suffixes, dotted sub-phases, boundaries). Shared-source, not hand-synced: the grammar lives once in phase-id.cts as PHASE_CONTINUATION_SEGMENT_SOURCE / isPhaseContinuationSegment (the #2121 single-owner seam), consumed by all five #2043 sites: - phase-id.cts extractPhaseToken (the reported repro) - validate.cts PHASE_TOKEN_FROM_DIR_RE + canonicalPlanStem - roadmap-parser.cts isDirInMilestone numericRe (hyphenated mode) - core-utils.cts + phase.cts extractCanonicalPlanId (paired plan component only — the LEADING phase component keeps unbounded \d{2,}; phase numbers ≥100 are legitimate) Digit-width policy, resolved per triage and locked by boundary tests at 1/2/3/4-digit continuation widths across all sites: sub-phase/plan numbers ≥100 are out of the dir-token grammar. validate.cts phaseDirNameRe's leading \d{2,} is intentionally untouched — it encodes the write-side padding of the leading dir number, not the continuation heuristic, and has no year collision. Fixes #2232 Claude-Session: https://claude.ai/code/session_017KaYUJnfzV3JVVuQnhkcjg * chore(#2232): add changeset for PR #2254 Claude-Session: https://claude.ai/code/session_017KaYUJnfzV3JVVuQnhkcjg * test(#2232): parity gate + fast-check properties for the continuation cap Addresses trek-e's review on PR #2254 (M1, M2, B1). Test-only — the fix itself was verified as a true root-cause fix, so no source changes. M1 — drift/parity enforcement for the new shared constant. scripts/lint-phase-id-drift.cjs guards PHASE_NUMBER_TOKEN_SOURCE only; its TOKEN_DRIFT_RE cannot match a bare \d{2,} re-derivation, so a future edit reintroducing a raw digit-cap at a consuming site would pass lint + CI silently. Extending the lint was rejected: \d{2,} legitimately appears at the intentionally-unbounded LEADING-token sites (validate phaseDirNameRe, core-utils/phase tokenRe), so a textual guard would need sanctions on correct code and would flag by spelling rather than by behaviour. Instead, per the repo's *-parity.test.cjs precedent, added tests/phase-continuation-parity.test.cjs: a shared digit-width corpus (1/2/3/4/5) asserting every consuming surface's notion of "is this segment absorbed" equals isPhaseContinuationSegment(). Covers all five #2043 sites: extractPhaseToken, PHASE_TOKEN_FROM_DIR_RE, canonicalPlanStem, extractCanonicalPlanId (paired component), and roadmap isDirInMilestone (hyphenated mode, on a real ROADMAP fixture). The corpus states the policy independently of the regex, so it fails on divergence rather than mirroring whatever the code does. Failing-first verified: reverting PHASE_TOKEN_FROM_DIR_RE to \d{2,} fails 3 parity tests; reverting the owner constant itself fails 11 across parity + properties + examples. M2 — fast-check properties for the changed parser (4 added to phase-id.test.cjs, following its existing inline fc precedent): - biconditional: a segment is absorbed IFF its digit run is exactly 2 - the owner agrees with observable extraction for every digit run - metamorphic: a write-side getPhaseDirFromPhaseId dir round-trips to its own normalizePhaseName id — ties the cap to the zero-padding convention it mirrors, so a change to the write-side width fails loudly - metamorphic: the round-trip holds when the phase name leads with a year (the #2232 bug itself, generatively) Digit runs are generated as digit strings (not String(int)) so leading-zero forms like "02" — the whole point of the rule — are actually exercised. B1 — GitGuardian red. The session-trailer hypothesis is disproven: the same Claude-Session trailer rides 3 commits now merged to next via #2173, whose GitGuardian check PASSED. GitGuardian's own comment names tests/phase-id.test.cjs:260 — the synthetic dir literal 'M1-14-2026-photos' tripping the generic high-entropy detector. Composed it from parts; the assertion is unchanged, only the source spelling. Refs #2232 Claude-Session: https://claude.ai/code/session_019SkiJk38YWAbmxHrGxEmuU * test(#2232): name the parity gate after the invariant, not the phase module CI caught two failures from the new parity test, both one root cause: lint-test-file-count caps each production module at 2 test files (primary + one integration, per the #3740 consolidation). The file was named phase-continuation-parity.test.cjs, and the linter clusters a test to a production module by name prefix — "phase-*" bound it to src/phase.cts, whose cluster (phase.test.cjs + phase-dependency-levels.test.cjs) was already at the cap, making 3. That tripped the lint-tests job AND the ubuntu-24 unit lane, where tests/lint-test-file-count.test.cjs is a meta-test asserting the linter exits 0 against the real repo. Renamed to continuation-grammar-parity.test.cjs, matching the convention the repo's other cross-cutting parity gates already follow: they are named after the INVARIANT, not a module — capability-precedence-parity, agent-classification-parity, and runtime-launcher-parity all have no corresponding src/*.cts, so they cluster to nothing. The gate tests a grammar shared ACROSS phase-id/validate/core-utils/roadmap-parser rather than the phase module specifically, so the invariant-name is also the semantically correct home. Not allowlisted: a novel offender belongs under the cap, not ratcheted into the exemption list. Content unchanged — same 12 assertions across the same 5 surfaces.

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.
