- Merge: click a room, then a neighbour. Adjacency is decided by the RESULT, not a heuristic: mergeRooms unions the outlines and accepts only when they collapse into one hole-free outline (corner touch / apart / hole => refused). A dialog picks the surviving name+area; the kept room keeps its id so its label and devices stay put. - Split: click the room, then two wall points; the chord cuts it, live ruler on the cut. The bigger part stays the room (name/area/devices), the smaller opens the new-room dialog. The cut is applied only on confirm — Cancel leaves the room whole. - Boolean geometry via polyclip-ts (proper ESM + native types; polygon-clipping ships named types but a default-only ESM build, breaking either tsc or the runtime). Verified on the real plan, where neighbouring walls overlap collinearly rather than match exactly — the case a hand-rolled union gets wrong. Bundle 151->202 KB. +5 tests (72). Verified live: merge of Сауна+с/у -> 4-vertex outline, non-adjacent refused, split preserves area (26667 -> 13333+13333), cancel leaves the room whole.
