+# Quick Task 260317-l9s: CI/CD Tag-Only Trigger Summary
+
+**Restricted CI/CD workflow to trigger exclusively on v* tag pushes, removing branch push and PR triggers with simplified job conditions**
+
+## Performance
+
+- **Duration:** 1 min
+- **Started:** 2026-03-17T14:20:56Z
+- **Completed:** 2026-03-17T14:22:16Z
+- **Tasks:** 1
+- **Files modified:** 1
+
+## Accomplishments
+- Removed `branches: [main, develop]` from `on.push` trigger
+- Removed `pull_request` trigger entirely
+- Simplified 6 job `if` conditions by removing redundant ref/event checks
+- Updated stale comments to reflect tag-only trigger model
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Restrict workflow trigger to tag push only and simplify job conditions** - `cac601d` (chore)
+
+## Files Created/Modified
+- `.github/workflows/ci-deploy.yml` - CI/CD workflow now triggers only on tag push matching `v*`
+
+## Decisions Made
+- Simplified all job `if` conditions: since workflow only triggers on tag push, checks for `github.ref == 'refs/heads/main'` and `github.event_name == 'push'` are redundant and were removed
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- CI/CD will no longer trigger on pushes to main/develop or on pull requests
+- Deployments will only occur when a version tag (e.g., `v3.3`) is pushed
+
+## Self-Check: PASSED
+
+- [x] `.github/workflows/ci-deploy.yml` exists
+- [x] `260317-l9s-SUMMARY.md` exists
+- [x] Commit `cac601d` exists
