Follow-up to d0c5461's .backgrounds/ folder: generating, pasting, or
choosing solid now trims the app's own prior file in .backgrounds/ as
part of the same write when it repoints or unsets background.image
away from it — silent, best-effort, never blocking the gesture that
triggered it. A scheduled heal at every board open sweeps whatever
that trim declined or missed: any .backgrounds/ file the board's
current background.image no longer names, announced with a loss-row
notice in the loose-file relocation's own voice. Legacy root-level
references are untouched by both paths — the tidy scopes to
.backgrounds/ only, since that is the one folder the app can prove it
wrote into.
Removal is via FileManager.trashItem, matching the attachment-removal
precedent (recoverable, never a hard delete).
Supersedes applySolidBackground's earlier "facets.png survives on
disk" contract for the settled case: the ruling reads "unsets" as one
more shape of "repoints away from a .backgrounds/ file", so a settled
solid choice now trims the generated picture it displaces, same as
switching producers does. The superseded test and doc comment are
updated to the new behavior; the echo-window (no-reload-yet) case is
unaffected and still leaves the file in place.

New app-written background images (Theme tab ▸ Pattern, and Edit ▸ Paste
as Board Background) now land in a hidden `.backgrounds/` folder at
board root instead of beside index.md, matching the `.trash/` app-managed
pattern. `background.image` stores the qualified relative reference
(`.backgrounds/facets.png`); the resolver needed no change at all, since
it already accepted any relative path inside the board root — the same
mechanism that already resolved `art/backdrops/sunset.png` resolves the
new location for free. `BoardWriter.writeBoardImage` now creates its
destination folder if missing, since `.backgrounds/` won't exist until a
board's first generated or pasted background.
The Finder collision-ladder (`BoardStore.boardImageName`) is rescoped to
`.backgrounds/`'s own contents, and its overwrite-in-place check now
recognizes only the qualified form as "ours" — a legacy bare
`background.image: facets.png` from before this change is read as a
foreign reference rather than migrated, so a regeneration writes a fresh
`.backgrounds/` file and orphans the old one in place, per the no-migration
ruling. The Theme tab's Pattern/Solid mode-detection was updated to
recognize both the legacy and current spellings as the generator's own
output.
The board loader needed no change: `.backgrounds/` is a hidden,
non-UUID-shaped name, and `.skipsHiddenFiles` already keeps every hidden
entry off the lane walk before any name-based exclusion is consulted —
pinned with a new loader test. Deliberately did not add `.backgrounds` to
IntegrityRules' claimed-name/squatter-displacement table: that table
mirrors a specific existing DESIGN ruling this card doesn't amend.

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.
