Project context
A fictional operations platform lets customers connect automation clients. Broad API keys and inconsistent tenant checks make delegated access difficult to review.
Setup prerequisites
- Create a local authorization service and synthetic partner clients for two organizations; generate disposable test credentials only.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
- BAPIAUTH-101 · Define partner scopes from concrete API operations
- BAPIAUTH-102 · Bind delegated credentials to organization and client identity
- BAPIAUTH-103 · Return non-enumerating errors for unauthorized partner resources
- BAPIAUTH-104 · Enforce authorization in nested and batch partner operations
- BAPIAUTH-105 · Rotate partner credentials without indefinite dual-key access
- BAPIAUTH-106 · Revoke partner access across cached authorization decisions
Acceptance criteria
- Apply both client and organization budgets.
- Return documented retry guidance.
- Keep denied requests from consuming unrelated client authority.
Implementation constraints
- Use deterministic local counters and no customer profiling.
Verification to include
- Exercise separate clients within the organization ceiling.
- Create multiple clients and verify the shared cap holds.
Deliverables
- Delegated rate-limit contract.
Rollout and recovery
Start with published conservative limits and inspect false rejection cases.
Value of the work
For the engineer: Practice delegated authorization, resource scoping, and secure public API ergonomics.
For the team: Provide usable partner access that remains least-privilege and revocable.
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.
