Project context
A fictional support console can reveal protected account settings and run repairs. The team needs bounded elevation, clear reasons and durable records of what happened.
Setup prerequisites
- Create synthetic support actors and organizations.
- Implement a local authorization boundary and append-only audit store.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
- AAUDIT-101 · List support actions with required permission and disclosure level
- AAUDIT-102 · Require a bounded purpose record before support elevation
- AAUDIT-103 · Remove sensitive account fields from ordinary support search
- AAUDIT-104 · Reauthorize elevation immediately before a support repair commits
- AAUDIT-105 · Commit privileged repair state and its audit fact together
- AAUDIT-106 · Make support repair commands replay-safe without repeating side effects
Acceptance criteria
- Every privileged authorization checks the stored expiry.
- Cleanup only archives derived state and cannot extend authority.
- Use one documented exact-expiry boundary.
Implementation constraints
- Use an injected UTC clock at the service boundary.
Verification to include
- Authorize a matching action immediately before expiry.
- Advance to expiry while cleanup is paused and deny the action.
Deliverables
- Expiry enforcement and paused-cleanup test
Rollout and recovery
Enable boundary checks before cleanup changes; revoke grants if clock assumptions are violated.
Value of the work
For the engineer: Practice privileged workflows, denial paths and audit integrity.
For the team: Review accountable support operations without unnecessary access to customer data.
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.
