test-fault-replay

name	test-fault-replay
description	Design and execute fault-injection, interruption, idempotency, migration, or replay tests for the runtime, persistence, provider and bundle boundaries.

Test fault and replay behavior

Workflow

1. List side-effect boundaries and commit points.
2. Add deterministic fault hooks before/after each boundary.
3. Execute crash/cancel/timeout at each hook.
4. Restart from persisted workspace.
5. Verify state machine, evidence completeness and no duplicate committed action.
6. Compare event/projection checksums against expected fixture.
7. Test duplicate command and finalize idempotency.
8. Test migration/upcaster before replay when relevant.
9. Test missing/corrupt artifact behavior without silently healing evidence.
10. Record operational envelope and untested fault classes.

Boundaries to prioritize

• CAS temp/write/rename;
• SQL transaction commit;
• provider request send/response receive;
• UCI process start/read/timeout;
• Parquet/bundle finalization;
• signal cancellation;
• budget reservation/release.
