Warp.
On a loom, the warp is the set of vertical threads held under tension — the frame everything else crosses. In Weft, the warp is your plan: sprints, priorities, the goal of the week.
What the warp holds
- The active sprint — a single named thread stretched across the week. It has a goal, a start, and an end.
- Priorities on tasks —
urgent,high,medium,low, and no-priority. They tell you which thread is under the most tension. - Due dates — hard stops that make the plan real.
Why the warp matters
Without it, your board is a pile of cards — you can work anything, so you work nothing urgent. The warp creates tension. “This sprint is about launching the landing.” is a warp statement; it turns Backlog items into Not-This-Sprint items, and that subtraction is what makes the sprint end.
For solo founders, the warp is the missing product manager. You will not hold a weekly planning meeting with yourself, so the sprint is the meeting — it asks you to commit out loud, once.
Changing the warp mid-sprint
Short answer: you can, Weft will not stop you. Longer answer: you probably shouldn't. A sprint you edit daily is a Backlog with a deadline. When the warp moves, the weft (your daily work) loses its frame.
