A rota of three, and a handover note

A third person on the rota, and the artefact that makes a weekly rotation work.

## Handover, week of 2025-01-13

**Open**
- supplier B's webhook has been retrying since Friday.
  their support ticket: SUP-4182. no action needed
  unless it is still failing Wednesday.

**Changed this week**
- the queue alert threshold is 60s, was 30s. deliberate.

**Watch**
- the monthly invoicing run is Thursday 02:00. it has
  never failed. if it does, runbook 6.

Three sections and a five-minute write-up is the whole mechanism, and it is what turns a rotation from a handover of a pager into a handover of context. The “watch” section is the one that matters — knowing that something unusual is scheduled is the difference between a considered response and a cold start.
