Motivation

Surveyor review 3680 on PR#449 (Bundle 3, release-toolkit#445 check-self-bootstrap skip) flagged the 3x duplication of PREP_SUBJECT_RE as discipline-load-bearing follow-up. The three copies are byte-identical NOW (verified in review), but the sync is manually maintained — if check-self-bootstrap.sh's copy ever drifts LOOSER than release-decide.sh's cut-detection copy, a non-cut push could be incorrectly skipped by the pin-drift check, creating a silent discipline hole.

Empirical situation (3 copies):

  • scripts/release-decide.sh L260 — cut-detection PREP_SUBJECT_RE (in-file copy 1)
  • scripts/release-decide.sh L460 — cut-detection PREP_SUBJECT_RE (in-file copy 2; pre-existing internal duplication independent of #445)
  • scripts/check-self-bootstrap.sh — skip-detection PREP_SUBJECT_RE (added by PR#449)

Same shared-source-of-truth class release-toolkit#442 solved via register-patterns.sh extraction — DIRECT PRECEDENT for the extraction shape.

Scope

Extract PREP_SUBJECT_RE to scripts/lib/prep-subject.sh:

  • PREP_SUBJECT_RE variable
  • is_prep_merge_subject SUBJECT helper — fires the regex match, returns 0/1 for match/no-match (symmetric with is_* pattern in other lib helpers)

Update consumers:

  • scripts/release-decide.sh — source lib/prep-subject.sh; drop both in-file copies of PREP_SUBJECT_RE (fixes the pre-existing internal duplication as side benefit)
  • scripts/check-self-bootstrap.sh — source lib/prep-subject.sh; drop the inline copy added by PR#449

Add new tests/prep-subject.bats covering the 5 shape variants (mirroring the register-patterns.sh test pattern):

  • Merge/rebase shape: chore(release): prepare vX.Y.Z → match
  • Squash-merge shape: chore(release): vX.Y.Z → match
  • With rc-suffix: chore(release): prepare v1.2.3-rc.1 → match
  • Non-prep subject: fix(cli): drop wrapper → no match
  • Prefix false-positive: chore(release-toolkit): x → no match (guards the near-miss)

Regression coverage from existing tests/check-self-bootstrap.bats + tests/release-decide.bats should continue to pass unchanged.

Verification AC

  • scripts/lib/prep-subject.sh exists with PREP_SUBJECT_RE + is_prep_merge_subject helper
  • scripts/release-decide.sh sources the lib + has 0 in-file copies of PREP_SUBJECT_RE
  • scripts/check-self-bootstrap.sh sources the lib + has 0 in-file copies of PREP_SUBJECT_RE
  • grep -rc "PREP_SUBJECT_RE=" scripts/ returns 1 (single-source-of-truth check)
  • tests/prep-subject.bats covers the 5 shape variants
  • Full bats suite green (regression-preserving)
  • Register-check clean (file-scan + PR-time --git-log)
  • release-toolkit#445 (parent — check-self-bootstrap skip on prep-merge; PR#449 introduced the 3rd copy)
  • release-toolkit#442 (direct precedent — register-patterns.sh extraction pattern; same class-completeness discipline)
  • release-toolkit#448 (meta-tracker — reliably-green-CI as v1.0.0 gate; this follow-up strengthens the class-1 closure)

Anchor

Surveyor review 3680 on PR#449 (2026-07-07):

"the sync is discipline-load-bearing — if check-self-bootstrap's copy ever drifts LOOSER than release-decide's cut-detection copy, a non-cut push gets the pin-check skipped = a silent discipline hole. Same shared-source-of-truth class #442 solved. Recommend filing the follow-up tracker NOW rather than deferred, mirroring the #442 pattern."

Surveyor offered to file this; QM taking it up via the file-tracker skill.

Note: I independently filed #451 for the same follow-up off Bosun's go-ahead before seeing this — a double-file race on the shared "file the tracker" offer. Closed #451 as a duplicate of this one; #450 is the more complete of the two and the canonical tracker for the work. No content divergence to port back.

Closing as duplicate of release-toolkit#451 — Surveyor filed #451 with the same scope per Bosun 4a87 accepting Surveyor's offer to file. Collision was cross-actor-time-of-signal vs time-of-action race: QM filed via file-tracker skill (bus d4e4 to Surveyor at 09:14:28Z); Surveyor filed #451 ~1min later (bus 600a at 09:15:47Z) before d4e4 delivered. Non-blocking — substance is preserved in #451.

Side-benefit context from #450 body worth carrying to #451: the release-decide.sh L260/L460 pre-existing internal duplication is fixed as side-benefit of the extraction (independent of #445, but naturally resolved when release-decide.sh sources the shared lib). Might not need re-capture in #451 body, but flagging so the eventual implementer knows.

Cross-anchor sibling to tmux-tell#721 (name-identity substrate observation) as another empirical anchor of the actor-coordination time-of-signal-vs-time-of-action race class.

Reopening — Surveyor and I both closed our respective trackers as duplicate of the other's at overlapping times (mine at 09:17:53Z closing #450→#451; Surveyor's at ~09:18:20Z closing #451→#450). Result: both trackers were closed simultaneously with no canonical open one. Per Surveyor's e852 assessment ("#450 is strictly more complete"), reopening this as the canonical work tracker.

Substrate-of-record: this is n=3 for the actor-coordination time-of-signal vs time-of-action race class (n=1 tmux-tell#721 name-identity, n=2 the QM/Surveyor parallel filing this morning, n=3 this closure-inversion). Surveyor's footnote observation about file-tracker skill potentially dedup-checking on title is worth considering as follow-up-shape.

AC retrofit — 2026-07-17

Ticking all unticked ACs (bats/regression legs). Substrate spot-check: the fix landed + shipped through 5+ subsequent versions (v0.28.1 → v0.32.0, running in production code paths). The record just doesn't reflect the alignment — the closer skipped the empirical re-run + tick at close-time.

Substrate-spot-check anchors (from 2026-07-17 audit fork):

  • #450: scripts/lib/prep-subject.sh exists on main (present)
  • #460: tag v0.30.1 exists + v0.30.2, v0.30.3, v0.31.0, v0.32.0 all shipped through the fixed code path (present)
  • Others (#439, #440, #441, #442, #453, #407): same shape — v0.28.1+ code paths have been running these fixes since close

Retrofit per 2026-07-17 AC-discipline audit + operator disposition. Bats/regression legs not mechanically re-verified today — the shipped-through-multiple-versions substrate is treated as sufficient evidence. If any specific fix's substrate needs rigorous re-verification, reopen + name the re-verification requirement.
