# US02-02 — Persist and Coordinate Durable Jobs
|
|
|
|
Epic: [E02](../E02-unified-workflow-shell.md)
|
|
|
|
As an operator, I want jobs and item progress stored durably so work can resume after
|
|
browser, API, or worker interruption.
|
|
|
|
## Acceptance criteria
|
|
|
|
- Job, item, event, attempt, progress, cancellation, and terminal states are persisted.
|
|
- Commands support idempotency keys and atomic state transitions.
|
|
- Prerequisites and one-mutating-job policy produce explicit blockers.
|
|
- Progress derives from durable item state rather than browser memory.
|
|
|
|
## Automated tests
|
|
|
|
- State-machine/property tests reject invalid transitions and duplicate terminal state.
|
|
- Repository tests cover concurrent idempotent submission and restart persistence.
|
|
