CLAUDE.md 925 -> 165. 789 of those lines were a verbatim paste of upstream's
flutter/flutter rules.md -- 85% of an always-loaded file given over to a
document nobody edits. It moves to five topic files under docs/, linked
rather than @-imported: inlining it back would pass the cap while keeping it
in context on every turn, which is the cost the cap exists to remove.
Every `###`/`####` heading in the upstream block survives the split; the two
that do not are its own wrapper headings, replaced by the per-file titles
(verified by diffing the sorted heading lists).
desktop-performance-findings.md 278 -> 73 + 216. It was already narratively
two-part; the author signposted "Part 2" explicitly at the seam.
Also updates two things that had drifted: the suite is 313 tests at 100%
coverage (not 238), and Conventions now documents the cap, where the gate
lives, and the two patterns used to split without breaking callers
(re-export barrels, and `part` files where a private State must stay in one
library).
`bash ~/utils/scripts/check_file_length.sh --all` now exits 0.
