PRACTICE GUIDE · 28 OCTOBER 2026

Make room.
Keep the ground rules.

Reflow is a single-day scheduling prototype. It lets you explore what can move, explain the trade-offs and role-play the people affected. It does not send messages or change anyone’s real calendar.

Three kinds of time

Try the example day

  1. Open “A busy workday” and request a 60-minute event.
  2. Keep equal and higher priorities protected for the first attempt.
  3. Compare the proposed calendar with the unchanged current plan.
  4. Preview notifications and act as each fictional participant.
  5. Try a counter-request, then review and approve the new revision before applying it.

What a no-fit result means

The requested event may not fit within the day’s fixed events, durations, windows and protected priorities. Change only the rules you are actually willing to change. A search-limit message means the search stopped before proving the lowest-cost answer.

Know the limits

The current engine uses a 09:00–18:00 day, a 15-minute grid, at most 12 total events and a 250,000-node search limit. Its movement score is a comparison rule, not money or a measured human burden.

Keep a copy

The planner saves locally in the current browser. Export JSON before clearing storage or moving devices. Notification previews and role-play approvals are session state. Cloudflare measures page visits and performance; the planner does not send your event contents.
