Every geometry mutation previously bumped a monotonic geometry_epoch and each derived cache compared its stamp and, on a miss, re-walked the whole document — so drawing or moving one line rebuilt every hatch / image / mesh / wipeout model even though none of them changed. Add a per-mutation delta journal: bump_entities(&[(Handle, ChangeKind)]) records exactly which handles changed (Added / Removed / Modified), folding the memo drop and the epoch bump into one call a site cannot forget. A bounded ring keeps the recent deltas; replay_since(last_epoch) coalesces the changes past a consumer or returns None (full rebuild) when a spanned delta is `full` or the consumer fell off the ring. bump_geometry / bump_geometry_no_blocks push a `full` delta so the journal is never missing a step. Route the common single-entity ops through it: add (Added), update (Modified), erase (Removed), move/rotate/scale/mirror (Modified), copy (Added). Gate the four per-category model caches on category relevance — an edit whose handles are not in a category leaves that category cache warm; a removal is treated conservatively (the erased handle can no longer be classified), and the mesh cache also invalidates on any INSERT edit since it carries the instanced block meshes. Net: a plain-entity edit no longer rebuilds the hatch/image/mesh/wipeout model sets. The resident wire clone-all and the GPU re-upload are still whole-set — the journal is the groundwork for making those per-entity next. Adds 6 journal unit tests (replay, coalescing, full-fallback, ring overflow, category gate). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
