Project context
A fictional logistics platform sends shipment events to partner endpoints. Partners need stable schemas and recovery semantics despite duplicate delivery, failures, and subscription changes.
Setup prerequisites
- Create a local webhook sender and receiver doubles with synthetic shipment events and disposable signing keys.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Derive organization scope from authenticated authority.
- Validate permitted event types.
- Recheck subscription authority before delivery.
Implementation constraints
- Endpoint ownership does not grant access to event data.
Verification to include
- Create a scoped synthetic subscription.
- Reject foreign-organization event scope and unauthorized event types.
Deliverables
- Subscription authorization boundary.
Rollout and recovery
Enable subscriptions only after cross-tenant denial checks pass.
Value of the work
For the engineer: Practice public event contracts, delivery guarantees, and partner recovery workflows.
For the team: Provide inspectable asynchronous integration behavior with controlled retries and clear compatibility.
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.
