# Gate 4 Checklist (Pilot Hardening)

- [x] Load test target reached (100 voice + 100 digital)
- [x] Backup and restore verified
- [x] Security checklist completed
- [ ] UAT signed with real operators/supervisors
- [ ] P1/P2 defects closed
- [x] v1 release notes and runbooks delivered

Verification run (2026-02-26):
- `python scripts/gate4_check.py`
- `pytest -q`

Pilot scope freeze:
- `docs/gates/mvp-pilot-baseline.md`
- `docs/roadmap/05-wave2-backlog.md`

Required manual evidence bundle before closing the last two checklist items:
- preflight report from `docs/uat/evidence/`
- completed session protocol from `docs/uat/session-template.md`
- filled defect log from `docs/uat/defect-log-template.csv`
- signed sheet from `docs/uat/signoff-template.md`
- updated `docs/gates/p1-p2-defects.md`

Manual close-out sequence:
1. Run preflight and automated dry-run to prepare the evidence pack.
2. Execute real UAT with operators and supervisor on the frozen MVP scope.
3. Fix only `P1` and `P2` issues, then rerun regression checks.
4. Capture sign-off and only then mark the final two checklist items as done.

Notes:
- UAT sign-off must be completed on pilot site with real operators and supervisor.
- P1/P2 closure is finalized after pilot UAT defect intake.
- UAT package location: `docs/uat/`.
- Automated dry-run command: `python scripts/uat_dry_run.py --auto-start --update-defect-register`.
