🏆 Why B wins

Round 2 puts B ahead, 23 to 22; in round 1, Greg's purpose broke the tie: booth accuracy and the right shapes
B's geometry agrees with the spec and the 2024 plan
B read the plan over the brief: west wall within 2 in of the spec
B's booth matches the photos, and the room is lit so it reads

🤖 Did Opus beat Fable at 3D? No

A (Opus) built the better application shell
B (Fable + Opus) modeled more accurately where judgment mattered
A's tools are now in B: plan with dimensions, schedule panel, collision, a fourth scene

✅ 12 fixes applied to build B in pass 10

✓ Collision
✓ Orthographic plan with dimensions
✓ Walls, grille, camera and downlights in the schedule
✓ Schedule panel
✓ Charcoal sectional: done, reads brown under session light
✓ Piano detail
✓ Booth oak floor
✓ Ceiling inset cleanup
✓ Keys rig on the south wall x 37..90, player facing north
✓ 29 in booth vestibule from the plan
✓ Swivel clearance
✓ 10 vertical guitars at 88 in

Later, cosmetic: near-wall frames dark, wall inset being raised in pass 11 · sectional reads brown under session light · phone plan labels clip at 390 px, pass 11 · a reflected-ceiling plan toggle would help the electrician · first load 16 s on a cold cache
