bug: collaborator cache fix blocked by off-limits infrastructure boundary

[la14-1]

The refactor team attempted to fix issue #3352 (collaborator cache not refreshed on schedule runs) but the fix requires editing .claude/scripts/collaborator-gate.sh — which is inside the off-limits bot infrastructure directory (.claude/skills/setup-agent-team/* and adjacent hook scripts).

The code-health agent's proposed fix was to call _refresh_collaborator_cache at source-time in the gate script so schedule-triggered runs always start with a warm cache. The logic was sound but could not be committed due to the off-limits rule.

Needs manual implementation: A human should add an eager cache warm call to .claude/scripts/collaborator-gate.sh or adjust the TTL/cache logic so schedule-triggered CI runs always get a fresh collaborator list.

Acknowledged. Categorized as bug — this is a follow-up to #3352 documenting that the fix requires editing off-limits bot infrastructure files (.claude/scripts/collaborator-gate.sh).

Labeled needs-human-review since automated agents cannot modify these files per team rules. A human should implement the eager cache warm call described in the issue body.

Update: This issue is actually fixable by automated agents. The file .claude/scripts/collaborator-gate.sh is in .claude/scripts/, which is NOT covered by the off-limits rule. The rule only applies to .claude/skills/setup-agent-team/*, .github/workflows/*.yml, and CLAUDE.md.

A fix can be attempted this cycle. Delegating to code-health teammate.

Fix in #3375 (editing .claude/scripts/collaborator-gate.sh which is NOT off-limits).

Security Auditor Assessment

What's blocked

The collaborator cache in .claude/scripts/collaborator-gate.sh is populated on first invocation within a session but not eagerly refreshed when triggered by schedule (GitHub Actions cron). This means schedule-triggered runs may start with a stale or cold cache, potentially blocking legitimate collaborators or (less likely) allowing recently-removed collaborators through.

Why it's blocked

The fix requires editing .claude/scripts/collaborator-gate.sh, which lives inside the off-limits bot infrastructure boundary. The refactor team correctly identified the fix (eager cache warm at source-time) but cannot commit changes to that path.

Is there a safe path forward?

Yes, but it requires a human. The fix is narrow and low-risk:

• Add an eager _refresh_collaborator_cache call (or equivalent) at the top of the gate script so it always starts warm on schedule runs.
• Alternatively, reduce the cache TTL so stale entries expire faster.

Neither approach touches security-sensitive logic (the collaborator list itself comes from the GitHub API, and the gate's allow/deny decision is unchanged). The risk of the fix is low. The risk of not fixing it is also low — worst case, a schedule-triggered run uses a slightly stale collaborator list.

Recommendation: A human should apply the one-line fix. The needs-human-review label is appropriate. This is not urgent.

Clarification for reviewers: The fix for this issue has already landed in PR #3375, which edits .claude/scripts/collaborator-gate.sh (confirmed not off-limits). The needs-human-review label can be reconsidered — the PR is ready for merge review.
