Audit-trail & transaction consistency (spec §11 "one transition, one row"):
- Action types: returnSalary/returnSelection/declineInterviewWaiver no longer
mislabel a backward decision as its forward action. New CrewActionType members
SALARY_RETURNED / SELECTION_RETURNED / WAIVER_DECLINED; added RECORD_DELETED;
dropped the unused GATE_FAILED (migration recreates the enum).
- Deletions are audited: deleteDocument / deleteNextOfKin now write a
RECORD_DELETED CrewAction (PII removals are traceable).
- Atomicity: autoRaiseRequisition takes an optional tx so the leave-clash and
sign-off backfills are created INSIDE the approval/sign-off transaction; the
office notification (notifyAutoRaised) fires after commit. An approved leave or
a sign-off can no longer commit without its backfill requisition.
Tests assert the corrected action types (crewing-gates, crew-records) and the
existing clash/sign-off suites still pass with the in-transaction backfill.
