Project context
A fictional export worker shares a long-lived object-store credential across environments. The team needs a provider-neutral identity boundary with safe expiry and revocation.
Setup prerequisites
- Create a local identity issuer and object-store double using generated test-only keys; no cloud account or production secret.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Validate issuer and exact audience.
- Bind workload and environment identity.
- Reject unknown signing keys and algorithms.
Implementation constraints
- Use generated local test keys only.
Verification to include
- Accept a matching assertion.
- Reject wrong audience, environment, and algorithm fixtures.
Deliverables
- Assertion verifier.
Rollout and recovery
Fail closed on unresolved trust configuration.
Value of the work
For the engineer: Practice workload identity, audience restrictions, and credential lifecycle failures.
For the team: Produce a migration path that narrows credential scope and makes revocation observable.
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.
