Verifies the mastery_gate_events audit log (REQ-NFR-MAST-02) is queryable by
learner, by path, and by date range, and that the evidence (scenarios_passed,
rubric_scores) is persisted and reconstructable as structured JSON.
Three events are inserted across two learners and two paths; queries verify:

- list_gate_events(learner_id, path) filters by path
- raw SQL date-range query filters by recorded_at

"""Key-rotation operational drill (SLICE-09 TASK-09-08, grill Axis 3 MUST #2).
End-to-end operational drill:
1. issue 3 VCs with key A
2. rotate to key B (archive A as superseded)
3. issue 2 VCs with key B
4. verify all 5 VCs (3 from A verify against archived A public key,
2 from B verify against active B)
5. revoke one from each key
6. verify revoked ones fail
This is the one crypto procedure that, if broken, silently invalidates
every credential ever issued.
