The R13 backline plant sat down-stage (stage.z + 0.15), 0.29 m from the bass rig — it interpenetrated the bassist (C's R14 audit caught it). Move it up-stage-right to C's blessed pose (stage.x + w*0.36, deckY, stage.z - d*0.22): 0.75 m clear of the bass, behind the front line, flanking C's primitive ampStacks. Pose-only. Verified: draw/tri delta 0 (same GLB moved — pub 50 draws / ~183k tris, <=350); ?noassets unaffected (amp is fleet-gated dressing → 0 props, band placeholders, no crash). No other code — continuity + the ratified sit-clip deferral are closed. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

// PROCITY Lane D — the gig band + crowd (v3.0-beta, behind ?gigs=1).
|
||
//
|
||
// A Friday night at the venue: a 4-piece band on Lane C's stage (guitar / vocal / bass across the
|
||
// front, a seated drummer on the up-stage riser) and a mixed crowd at C's watch points — some
|
||
// standing, some dancing (John's "a bit of both"). Built on the gate-protected rig path
|
||
// (spawnRig → buildFigure, so no giants), with a placeholder fallback when the fleet is absent
|
||
// (?noassets — a gig with no GLBs is still a gig).
|
||
//
|
||
// Instruments: primitives show immediately (asset law), then E's manifest GLBs swap in async where
|
||
// present (placeholder-persists, like interiors/glb.js). guitar/bass held at the chest, mic stand +
|
||
// drum kit planted, an amp as backline dressing. Gated on fleet.ready so ?noassets never fetches.
|
||
//
|
||
// Seam: F builds one GigCrew per venue interior and calls spawn() when the gig state is doors/on,
|
||
// update(dt) each interior frame, disposeAll() on gig-off / room exit. C owns the stage + watch
|
