Project context
A fictional messaging service builds a read model from database changes. Restarts and schema changes can re-enable preferences that customers disabled.
Setup prerequisites
- Create synthetic preference records and a replayable local change log.
- Use adapters or fixtures without provisioning a production broker.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Log source position, safe record token and reason code.
- Exclude contact details and raw payload bodies.
- Retain restricted diagnostic access only through a scoped fixture store.
Implementation constraints
- Use synthetic contact data in disclosure tests.
Verification to include
- Locate a rejected envelope through its safe identifiers.
- Inject contact fields and assert they never appear in generic logs.
Deliverables
- Sanitized diagnostics and disclosure checks
Rollout and recovery
Deploy redaction before replay; restrict access to older diagnostic output.
Value of the work
For the engineer: Practice change-feed ordering, snapshots and privacy-preserving deletion.
For the team: Review whether replicated customer preferences remain correct during recovery.
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.
