15-minute normal shutdown, triggered at 17:45: (1) 3 min—capture loose promises/tasks from today's notes into Jira with source and real due date; done when notes have capture marks, not when tasks are completed. Reply now only if a hard same-day commitment would otherwise be missed. (2) 3 min—update the current Jira item with status, next action, blocker, and file link; skip Slack handoff unless a named London owner has accepted it. (3) 2 min—name/save Figma draft and Drive note with project/date, close duplicates; done when both links reopen. (4) 2 min—check tomorrow's calendar and identify conflicts only. (5) 3 min—prepare the first action: open a comparison note with the three issue IDs and evidence-link slots; write “08:30 compare available evidence; at 08:50 proceed without new researcher notes if absent.” Do not treat 08:45 notes as promised. (6) 2 min—store paper notes, lock laptop, and say “workday closed.”
Two-minute emergency: photograph no sensitive paper; instead place all paper in the locked drawer, add one Jira note containing current task/next action/file link, check the first calendar event, lock laptop. Any uncaptured thought goes on a single permitted paper capture card for next morning.
Friday maintenance: 15 minutes to review stale Jira items, broken links, and whether steps still earn their time. One-week trial: record shutdown duration and next-morning open loops discovered that were known the prior evening; target median ≤15 minutes and fewer misses than baseline, which must be measured during week one rather than invented.
