Go Backend Rollback Drill Final Closeout Delivery Retention

Go Backend Rollback Drill Final Closeout Delivery Retention

Status: complete for the current public-safe closeout delivery and retention review slice.

Completed implementation:

• Added final closeout summary connector delivery events.
• Added retention review request and approval metadata.
• Added downloadable closeout artifact bundles containing the closeout summary, readiness bundle, and signed archive manifest.
• Added Evidence Console controls for Deliver Closeout, Retention Review, Approve Retention, and Download Closeout Bundle.
• Added dashboard metrics for closeout delivery, retention review approvals, and artifact bundle generation.

API:

• POST /runtime/go-pilot/rollback-drill-notifications/acknowledgements/audit-delivery/final-reporting-release-closeout-summary/deliver
• POST /runtime/go-pilot/rollback-drill-notifications/acknowledgements/audit-delivery/final-reporting-closeout-retention-review
• POST /runtime/go-pilot/rollback-drill-notifications/acknowledgements/audit-delivery/final-reporting-closeout-retention-review/{review_id}/decisions
• POST /runtime/go-pilot/rollback-drill-notifications/acknowledgements/audit-delivery/final-reporting-closeout-artifact-bundle

Security boundary:

• Closeout delivery stores public-safe event and redacted connector metadata only.
• Retention review records approval state without implementing private retention policy enforcement.
• The downloadable bundle excludes private signing keys, archive credentials, customer data, and connector secrets.
