One file (AGENTS.md) that bootstraps the rest: rules, the file map to create,
what belongs in each file, the first-session interview order, and the list of
anti-patterns that killed the previous map (1,308-line guide, 63 task files,
narrative history inline, sessions skimming 56k tokens of context).
Separates four kinds of content by read frequency:
rules/invariants -> AGENTS.md (every session)
subsystem truth -> docs/ai/<topic>.md (only the matching one)
lookups -> environment.md (grepped, never read)
retired decisions -> decisions.md (only when re-opening one)
Caps are enforced, not promised: scripts/verify.sh checks doc budgets before
the build, so a commit that pads a capped file fails. Proven both ways — it
passes clean and exits 1 on an over-cap file.
scripts/scope-check.sh blocks edits outside the declared file list.
templates/ holds fill-in skeletons for the seven files a project must create.
CC0: copy it, rename it, sell it, no attribution needed.
