Second slice of Phase 4 (stacked on 4a crew records). Leave (site-applied,
Manager-decided) with clash auto-backfill, and the daily attendance calendar,
per Crewing-Implementation-Spec §5.3/§8.9–8.10. Behind NEXT_PUBLIC_CREWING_ENABLED.
What's in
- Schema (crewing_leave_attendance migration): LeaveRequest (LeaveType,
LeaveStatus) + Attendance (AttendanceStatus, unique per assignment+date) on
CrewAssignment; CrewActionType += LEAVE_APPLIED/LEAVE_DECIDED/ATTENDANCE_RECORDED.
- Leave (R1): site staff apply on behalf (apply_leave); Manager decides
(decide_leave) → assignment ON_LEAVE; MPO has no leave role. Leave approvals also
surface in the central /approvals queue (§8.13 Leave kind). Notification
LEAVE_FOR_APPROVAL.
- Clash auto-backfill (R6): lib/leave-clash.ts, required strength = 1 — approving a
leave that leaves the vessel with zero active same-rank cover auto-raises a LEAVE
requisition via the Phase-2 autoRaiseRequisition.
- Attendance (R5): daily month calendar; site staff record (record_attendance),
Manager views (view_attendance) but cannot edit, MPO neither. saveAttendance
bulk-upserts dirty cells.
- Screens: /crewing/leave (apply-on-behalf + Manager Approve/Decline) and
/crewing/attendance (tap-to-cycle calendar + Save). Leave + Attendance added to
the flag-gated nav (Manager + Site staff).
Tests & docs
- Integration: leave-attendance.test.ts (7) — apply/decide, clash auto-raise (and
no-raise when cover remains), MPO/Manager attendance lockout, permission gating.
type-check clean; full unit (240) + integration (182) green.
- CLAUDE.md updated with the Phase 4b surface.
Deferred: the 6-month leave-planner timeline (lightweight list for now); hours/
overtime attendance (A7).
