# Release Runbook (Atomic Cutover)
|
|
|
|
## Preconditions
|
|
|
|
- all prior phase gates complete
|
|
- signed release checklist
|
|
- rollback owner and communication owner assigned
|
|
|
|
## Cutover Sequence
|
|
|
|
1. freeze non-release writes and announce maintenance window
|
|
2. execute final backup snapshot
|
|
3. deploy release candidate build
|
|
4. run reset/reseed as planned for production state model
|
|
5. run post-deploy integrity and smoke checks
|
|
6. run mandatory critical-path E2E subset
|
|
7. publish completion and monitor
|
|
|
|
## Immediate Post-Cutover Checks
|
|
|
|
- auth and role gating paths
|
|
- transition mutation sanity
|
|
- assignment preview/execute path
|
|
- live cursor operations
|
|
- audience vote acceptance and dedupe
|
|
- reporting endpoint correctness
|
|
|
|
## Rollback Trigger Conditions
|
|
|
|
- integrity check failures
|
|
- critical mutation path failure
|
|
- unacceptable error-rate spike
|
|
|
|
## Rollback Plan (High Level)
|
|
|
|
- restore backup snapshot
|
|
- redeploy previous stable build
|
|
- validate critical-path smoke tests
|
|
- issue incident communication and postmortem schedule
