Write a restore handoff with promotion and abandonment criteria
An operator needs to decide whether a long-running restore is safe to promote.

Project context
A fictional reporting service has successful backup jobs but no recent restore rehearsal. Database rows reference objects with different retention schedules.
Setup prerequisites
- Create disposable local database and object-store fixtures with synthetic reports; author backup and corruption examples.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
- BRESTORE-101 · Inventory the data required to restore one report
- BRESTORE-102 · Define a consistent backup manifest across stores
- BRESTORE-103 · Guard restore commands against non-scratch targets
- BRESTORE-104 · Verify backup bytes before applying restored data
- BRESTORE-105 · Restore database references before enabling object reads
- BRESTORE-106 · Rebuild derived indexes from restored authoritative records
- BRESTORE-107 · Check application compatibility against restored schema versions
- BRESTORE-108 · Measure recovery time and recoverable data loss separately
- BRESTORE-109 · Rehearse recovery when the newest backup is unusable
Acceptance criteria
- List required integrity and compatibility checks.
- Document promotion authority and target identity.
- Explain how to abandon the scratch restore safely.
Implementation constraints
- Avoid destructive cleanup commands outside the named scratch directory.
Verification to include
- Follow the handoff to promote a valid fixture.
- Keep a restore with missing objects unpromoted.
Deliverables
- Restore runbook.
Rollout and recovery
Store the runbook with backup manifests and compatible build references.
Value of the work
For the engineer: Practice recovery consistency, integrity validation, and honest recovery objectives.
For the team: Replace backup-job optimism with a repeatable restoration assessment.
Evidence boundaries
Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.
Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
