Gate 4 Checklist (Pilot Hardening)

• Load test target reached (100 voice + 100 digital)
• Backup and restore verified
• Security checklist completed
• UAT signed with real operators/supervisors
• P1/P2 defects closed
• 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.
