Daily duty log shift accountability

What was done this shift (auto-compiled from the audit log above), the routine checks completed, and anything outstanding — submitted to the supervisor and kept as an immutable record.

“On duty” is the signed-in user for now — a duty roster is open decision D-1.

Routine checks

The read-only steps of the daily round — tick to attest each was done. The action steps in the table above are already in the audit log.

• Outstanding items reviewed on sign-in (alert ribbon + notifications) — step 2
• Alert queue worked to empty or explicitly handed over — step 3
• Every data source confirmed refreshed on schedule; Delayed/Failed noted — step 4
• Multi-hazard picture read for priority areas, at each hazard's cadence — step 5
• Each hazard's forecast read at its own horizon; multi-source hazards compared — step 6
• Slow-onset section checked separately — step 9
• Reference layers (exposure, vulnerability, risk baseline) checked; out-of-date flagged — step 10 · 1 flagged
• Historical events catalogue reviewed; past no-alert events completed — step 11
• Verification calibration notes reviewed — step 12
• Pending community / incident reports verified or carried forward — step 13 · 1 pending

Source health at end of shift

Submitting writes an immutable append-only record (actor, shift, timestamp), notifies the supervisor, and adds it to Duty logs below. It cannot be edited after submission — a correction is a follow-up entry.

Duty logs append-only

Shift	On duty	Submitted	Supervisor ack
2026-07-20 · 06:00–18:00	Rakoto · Analyst	2026-07-20 18:12	Acknowledged — Hery (Admin)	Open
2026-07-19 · 18:00–06:00	Naina · Analyst	2026-07-20 06:04	Pending ack	Open

The supervisor acknowledges each log; one left unacknowledged past 24h is flagged. Retained indefinitely for audit — the same append-only rule as the audit log above.
