### Changed

- BUILDER.md's green ruled term now says which entry to read before it says
  what an entry means: a check's word at a head is its newest entry by start
  time, and a cancelled entry is not that word while the same check carries a
  non-cancelled one at that head (#276).
- A check whose every entry at the head is cancelled is unchanged — nothing
  survived to be its word, so it never reported and is not green — and the
  collapse mirrors `checks_state`'s carve-out rather than adding a class
  (#276).
docs(builder): a displaced predecessor is not the check's verdict Step 1 ruled what a rollup entry means and never said which entry to read. A job in a cancel-in-progress group displaces itself, so a head routinely carries a CANCELLED node beside the SUCCESS that replaced it, and read by class alone that head is not green while checks_state calls it SUCCESS. State the collapse ahead of the classes it feeds: newest entry by start time, and a CANCELLED entry is not the check's word while a non-cancelled sibling stands at the same head. All-cancelled and pending are untouched. Refs #276 2026-08-04 10:58:59 +00:00			`### Changed`
