Summary

  • The pr-gate linked-issue regex required # to immediately follow the closing keyword, so PR bodies writing Fixes (#5315) parsed no linked issue and the gate auto-closed otherwise approved work (bit PRs Click and hold nukes #5374 and Click and hold nukes #5375).
  • Allow an optional parenthesis on either side of the reference: \s+\(?#(\d+)\)?\b.
  • Kept the trailing \b (unlike the raw suggestion in the discussion) so fixes #5315abc still links nothing — regex backtracking off the optional \)? makes this compatible with Fixes (#5315).
  • Added tests for Fixes (#5315), multiple parenthesized references, and lone-paren variants fixes (#7 / fixes #8).

Test plan

  • npx vitest tests/PrGateRules.test.ts --run — 40/40 pass (4 new cases).

The linked-issue regex required "#" to immediately follow the closing
keyword, so PR bodies writing "Fixes (#5315)" parsed no linked issue and
the gate auto-closed otherwise approved work (PRs #5374, #5375). Allow
an optional parenthesis on either side of the reference, keeping the
trailing word boundary so "fixes #5315abc" still does not link.

🤖 Claude Code Review

Verdict: Approve — no issues found. Findings: 0 critical, 0 major, 0 minor.

Summary

This PR fixes the pr-gate linked-issue regex in scripts/pr-gate/rules.ts to accept parenthesized issue references like Fixes (#5315), changing the pattern from \s+#(\d+)\b to \s+\(?#(\d+)\)?\b. Four new test cases were added to tests/PrGateRules.test.ts covering parenthesized and unbalanced-paren references.

Checks performed

  • CLAUDE.md compliance (2 independent reviewers): No violations. Neither changed file is under src/core (no test-mandate or determinism concerns), no user-visible text is involved (no i18n concerns), and the new tests follow the existing plain-Vitest style already used in tests/PrGateRules.test.ts (the setup() helper convention applies to core simulation tests, not this script-level test file).
  • Bug scan (2 independent reviewers, diff-only and introduced-code focus): No significant bugs. The regex change was traced through all four new test cases by hand — capture groups, backtracking behavior, and boundary (\b) interactions all produce the expected results, with no ReDoS risk (no nested/overlapping unbounded quantifiers) and no regressions to previously-guarded false-positive cases (cross-repo refs, keyword-only mentions, substring keyword matches).
  • One reviewer noted (as a non-issue, informational only) that the trailing \)? is effectively inert in practice since \b cannot hold immediately after ), so the regex behaves equivalently to \s+\(?#(\d+)\b — this doesn't change correctness and isn't flagged as a defect.

No inline comments posted — nothing met the bar for a finding.

The parser can treat malformed issue text as a valid link, and the new parser test violates the repository’s required test pattern. Both are narrow issues, so merge risk is low but they should be corrected.

Reject word suffixes after issue references

LINKED_ISSUE_RE can parse both fixes (#5315)abc and fixes #5315)abc as issue 5315. checkApprovedWork can then pass the PR when issue 5315 is approved and assigned to the author. This is outside the documented Closes #N / `Fixes `#N / Resolves #N`` reference format.

Guard the boundary before the optional ) (for example, (\d+)(?!\)\w)\)?\b) and add both malformed forms to tests/PrGateRules.test.ts with an empty result.

Resolve the test-path rule for parser tests.

This file matches tests/**/*.ts, but the added test does not call setup() from tests/util/Setup.ts or exercise the core simulation. Move PR-gate parser tests to an exempt path, or add a documented exception for non-simulation tests. Do not create a game instance only to satisfy this rule.

As per coding guidelines, tests/**/*.ts tests use a setup() helper from tests/util/Setup.ts and exercise the core simulation directly, not mocks.

…frontio#5315)" (openfrontio#5394)

## Summary

- The pr-gate linked-issue regex required `#` to immediately follow the
closing keyword, so PR bodies writing `Fixes (openfrontio#5315)` parsed no linked
issue and the gate auto-closed otherwise approved work (bit PRs openfrontio#5374
and openfrontio#5375).
- Allow an optional parenthesis on either side of the reference:
`\s+\(?#(\d+)\)?\b`.
- Kept the trailing `\b` (unlike the raw suggestion in the discussion)
so `fixes #5315abc` still links nothing — regex backtracking off the
optional `\)?` makes this compatible with `Fixes (openfrontio#5315)`.
- Added tests for `Fixes (openfrontio#5315)`, multiple parenthesized references,
and lone-paren variants `fixes (openfrontio#7` / `fixes openfrontio#8)`.

## Test plan

- `npx vitest tests/PrGateRules.test.ts --run` — 40/40 pass (4 new
cases).
