The paper agrees with the code — guide v11, README, DESIGN re-rulings, and the adjudicated sweep

Step 7 of strategy/01-git-excision.md, the companions. The agent guide bumps to v11: the Git section teaches repo-resident etiquette alone (stage only your own paths, commit your own changes, leave app-maintained files to the app) — existing boards heal to the new text on next open. README re-anchors: the four git feature bullets out, tiers say the complete Mac experience is free, and one bullet states the format's git-friendliness promise. The changelog drops the never-shipped git entries. DESIGN re-rules: 06 retired with Undo routing migrated to 13 (now the sole substrate's doc, seam kept open), 07 retired as written pending the ops-service workstream, 14 retired as superseded record, 12 carries the second pivot note, the index reflects all of it; the charter gets a pointer note (the anchors' full re-ruling stays with the user). InertGitTests renames to GitAgnosticStorageTests — the excision restores its original claim app-wide. And the sweep: ~70 comment sites across 36 files adjudicated against the keeper list, every present-tense description of the excised machinery made past tense or repointed, keepers untouched. 2,707 tests green.
