Every note here takes one part of the apparatus and works it out properly. Not the taste of it — the mechanics: what the constraint actually is, which numbers move and when, what the trade is when two requirements cannot both hold. The material is the part that is usually carried in somebody's head and discovered late.
The notes carry no dates. A run-sheet is the same problem in March as it is in September, and a seam allowance does not care what year it is. Where timing matters it is written as an interval — two weeks before collection, the caterer's cut-off, the twelve hours before the flowers are handled — rather than as a day on a calendar.
How each note is built
Every entry ends on the thing that actually governs it: the number, the constraint or the deadline. Where the material wants a table, a sequence or a list of failure modes, it is lifted out of the prose and set as its own panel, because that is the part people come back for.
We do not write about the legal or religious requirements of getting married. Those vary by jurisdiction and by congregation, and getting them slightly wrong in print is worse than not writing them at all.
