 - Keep-clear zones: the door swing square and the 0.6 m strip inside the opening, the 0.3 m strip under a wall screen, and obstacles. `getBlockedRects(room)` returns them all and `isValidPlacement` reads it, so furniture can't overlap them (red outline, drop blocked). Doors/screens can't sit on furniture or obstacles or share wall length; obstacles can't overlap furniture, each other, or door/screen zones.
 - Export downloads `room.json` (width, height, doors, screens, obstacles; no furniture). Import validates with `parseRoom` (`roomSchema.ts`) and shows a clear error; if furniture is placed it asks for confirmation first, and if the placed furniture doesn't fit the imported room it clears all furniture and warns.

+**Rules and scoring (Phase 4)** - measures the layout only; there is NO optimizer and nothing moves automatically.
+- All scoring is pure TS in `src/scoring/` (no React/Konva): `scoreLayout(room, items, configs, rules, weights, {debug})` returns the five sub-scores (0..1 or `null` = n/a), the 0-100 overall (`overallScore`, weighted average of the non-null scores by the 0-10 priority weights), issues (text + item ids), rule violations and optional overlay data. Roughly 12 ms for a 10x8 room, 85 ms for 60x60 with 120 items.
+- `seats.ts` `getSeatPoints`: N points evenly around a table's perimeter (seatsOverride, else type default); standalone seating = its center, or `seats` points along its long side; a single chair within 0.8 m of a table edge is that table's seat and isn't counted again.
+- `occupancy.ts`: internal 0.1 m grid (never drawn, nothing snaps to it) from `getBlockedRects` + the true rotated furniture, with a chamfer clearance transform and a Dial's-algorithm `reachFrom`. Cached per variant and rebuilt only when the room or items arrays change. Door keep-clear zones are walkable for pathfinding.
+- loadingScore: paths from loading doors (any door if none is marked) through >= 0.9 m clear width; 0.6 * fraction of items reachable + 0.4 * (1 - normalized avg path length). screenScore: per seat, angle off the screen normal (ideal <= 45 deg), distance (ideal 1.5-6x screen width), obstacles block line of sight (furniture doesn't); null with no screen. accessScore: per table, fraction of perimeter with 0.6 m free clearance reachable from a door; null with no tables. comfortScore: seat spacing (0.9 m), door distance (1.5 m), not flush to obstacles, blended with crowding (> 0.9 seats/m2).
+- Rules mode (third tab): list editor for keepApart, keepNear, screenDistance, doorDistance, againstWall, each with a priority (Required, High 3, Medium 2, Low 1). `evaluateRules` returns violations (rule id, item ids, meters off); `rulesScore = 1 - weighted violated fraction` over non-required rules. Required violations outline items in orange and are listed in the score panel but never block dragging.
+- Score panel (top of the sidebar in Layout mode, collapsible): overall number, five labeled bars with priority wheels, required violations, top issues (click to highlight items), and overlay toggles (loading paths, sight lines, table clearance; off by default). Weights and rules live in the store. During a drag the score recomputes at most ~10x/s.
+- Tests: `npm test` (vitest) covers seat points, empty room, reachable vs walled-off table, blocked line of sight, comfort, rules and the weighted overall.
