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
- Bind grant to resource and allowed operation.
- Enforce expiry and unique grant identity.
- Prevent the caller from widening scope.
Implementation constraints
- Grant fields derive from authorized server state.
Verification to include
- Write the intended synthetic export.
- Reject a different resource or operation under the same grant.
Deliverables
- Scoped grant issuer.
Rollout and recovery
Start with one export path; retain no broad fallback credential.
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.
