L1: memoized space model + open pairs (structural fingerprint key, epoch bumped synchronously at mutation time, not inside the debounce); hoisted per-room geometry out of the render loop; smoke asserts zero recomputation across state pushes. L4: openings get the 3 px drag threshold used by every other pipeline and only write when the geometry actually changed — taps open the dialog again. G2: interiorPoint() replaces the vertex mean, so island rooms inside concave (U/L) parents are accepted and their evenodd holes render; traced duplicates still are not containment. G3: segKey rounds before ordering — one shared wall, one key. B2: _check_write fails closed when the entry is unavailable. B3: layout/set honours expected_rev and returns the new rev. B4: config/set without expected_rev over a non-empty store logs a warning. B5: coordinates reject NaN/Infinity; spaces/rooms/markers/decor/layout capped. +2 unit tests (118), +2 backend tests (14), smoke_render_perf; docs same-commit
