v3.0-alpha band room. New pub recipe (venue:true): stage + PA + amps at the back wall (new stage/paSpeaker/ampStack fittings, GLB slots stage/pa_speaker/amp for E), bar counter (keeper), sticky carpet, blocked back door = green room.
buildInterior returns for venues: room.watchPoints[] (6-8 seeded audience poses {x,z,ry,dance} facing the stage, dance ~1/3, counter.stand ry convention); room.stage {x,z,w,d,deckY,frontZ,bandPoses[3]} for Lane D's band; room.audio.gigKey ('gig-'+genreKey) set when Lane F passes opts.gig.
Flags-off byte-identical: venue code runs only for recipe.venue on its own seed sub-streams; non-pub rooms have watchPoints:[], stage:null, unchanged placement/audio.
Verified: 40-seed pub sweep (0 throws/carves/path-fails, 8 watchPoints, dance 0.38) + 60-room mixed soak (0 det/path fails, leak geo0/tex0, worst 19ms). Non-pub unchanged. Interface for D/F: docs/LANES/LANE_C_PUB.md. scaffold + manifest green.

// PROCITY Lane C — the placer. Turns a recipe + room shell into a believable, non-overlapping,
|
||
// walkable arrangement of fittings + wall decor, seeded from shop.seed.
|
||
//
|
||
// Guarantees (LANE_C acceptance):
|
||
// • nothing overlaps — every fitting reserves cells in an occupancy grid before placing
|
||
// • wall art/signs don't clash — the thriftgod shuffled wall-slot system draws from one pool
|
||
// • door → counter is walkable — flood-fill verifies connectivity; blockers are pulled until it is
|
||
// • density varies by shop — count per fitting scales by recipe.clutter × area × seed
|
||
//
|
||
// Coordinates match shell.js: +Z = door/street side, −Z = back. Origin = room centre, floor y=0.
