Reconcile restored database references with external artifacts
Case attachments point to objects created after the backup cutoff, and some objects referenced by restored rows are missing.

Project context
A fictional case-management team has nightly backup files but has never tested application behavior after restore. Missing roles and external artifact references may make a successful database restore unusable.
Setup prerequisites
- Create a disposable synthetic database and local backup directory.
- Never connect these drills to production or overwrite a shared database.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
- ARESTORE-101 · Inventory database recovery inputs beyond the dump file
- ARESTORE-102 · Create a backup manifest that binds bytes to schema revision
- ARESTORE-103 · Validate that a restore target is isolated before running destructive steps
- ARESTORE-104 · Restore a verified backup into a new database generation
- ARESTORE-105 · Check relational invariants after restoration
Acceptance criteria
- Compare immutable object versions and hashes for referenced artifacts.
- Report missing, extra and mismatched objects separately.
- Do not replace missing artifacts with similarly named current objects.
Implementation constraints
- Use a local object-store fixture and explicit backup cutoff.
Verification to include
- Restore matching database and object manifests.
- Remove a referenced object and keep the application readiness result incomplete.
Deliverables
- Artifact reconciliation command
Rollout and recovery
Keep artifact-dependent routes unavailable until their references verify; preserve missing-reference reports.
Value of the work
For the engineer: Practice restore verification, provenance and operational recovery.
For the team: Review evidence that recovery produces coherent usable state under declared limits.
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.
