Summary

Adds a GitHub Actions workflow that posts a retro checklist comment when bug-labeled issues are closed.

What it does

• Triggers on issues.closed events for bug-labeled issues
• Posts a structured retro checklist as a comment
• Helps the team systematically learn from bugs

Workflow details

• Uses actions/github-script@v7 with minimal issues: write permission
• Follows existing squad-* workflow naming convention
• Includes concurrency group to prevent duplicate runs
• No changeset needed — CI-only change, no product source code modified

Closes #819

🧪 FIDO — Quality Review

Verdict: ⚠️ COMMENT

Test Coverage

• No tests. Workflow-only PR — acceptable for CI automation, but the workflow logic (label filtering, comment body) is untestable without a workflow test harness.

Edge Cases / Risks

• Missing timeout-minutes on the post-retro-checklist job. If actions/github-script hangs (GitHub API outage), this job runs until the 6-hour GitHub default. Add timeout-minutes: 5.
• No bot guard. If a bot closes a bug-labeled issue, the retro checklist still fires. Consider if: contains(github.event.issue.labels.*.name, 'bug') && github.event.sender.type != 'Bot'.
• Encoding issue. The emoji in the checklist body (🔍) appears as mojibake in the diff (🔄). Verify the file is saved as UTF-8.
• No duplicate prevention. If a bug issue is closed, reopened, and closed again, a second retro checklist comment is posted. Consider checking for an existing checklist comment before posting.
• actions/github-script@v7 is tag-pinned, not SHA-pinned. Per hardening conventions (PR feat(test): CI template hardening tests — 20 structural assertions [ON HOLD] #915), this should use a SHA pin.

CI Impact

• New workflow, no impact on existing CI. contents: read is missing from permissions (implicit default) — only issues: write is declared, which is correct.

Recommendation

Add timeout-minutes: 5, add duplicate-comment prevention, and consider bot guard.

🔒 RETRO — Security Review

Verdict: ✅ APPROVE

Security Findings

• No injection vectors. The comment body is a static markdown string — no user-controlled input is interpolated into it.
• \�ctions/github-script@v7\ is tag-pinned, not SHA-pinned. Acceptable for Phase 1, but tracked by the hardening roadmap (PR feat(test): CI template hardening tests — 20 structural assertions [ON HOLD] #915 A2).

Credential / PII Check

• No secrets or PII introduced. Uses the default \GITHUB_TOKEN\ for issue comments.

Workflow Permissions

• \permissions: issues: write\ — correctly scoped to minimum required (issue comments only).
• Concurrency block present with \cancel-in-progress: true.
• Bot guard: relies on \if: contains(github.event.issue.labels.*.name, 'bug')\ — label filter is sufficient; bots creating bug-labeled issues would trigger this, but the impact is a benign checklist comment.

Recommendation

Clean merge. Well-scoped permissions, static content, no dynamic input.

🏗️ Flight — Architecture Review

Verdict: ⚠️ COMMENT

Findings

• New workflow squad-bug-retro.yml is well-scoped: minimal permissions (issues: write only), concurrency block present, bot-label-filtered (�ug label).
• Uses �ctions/github-script@v7 with tag reference (not SHA-pinned). Acceptable for Phase 1 but should be tracked for SHA pinning per the hardening roadmap (PRD: CI Template Testing Infrastructure — Structural Tests & Pre-Release Validation #888 / PR feat(test): CI template hardening tests — 20 structural assertions [ON HOLD] #915).
• The workflow lives only in .github/workflows/ — NOT synced to .squad-templates/workflows/ or the other 3 template locations. This is the right call if this is a repo-specific workflow that shouldn't ship to users via squad init. However, if this is intended as a Squad feature that all squadified repos get, it needs template sync.

Module Boundary Check

• No boundary violations. Pure workflow addition, no package code touched.

Recommendation

Clarify intent: is this a Squad platform feature (needs template sync) or a repo-specific workflow (current placement is correct)? The workflow itself is clean.
