R14 review found every venue's own-frontage poster on the building's −Z BACK since R13 (~16 m
behind the street face, B measured 15.9 m) — invisible from the street, why queue_night framed no
poster. Ledger #1, A-first (B's hero re-shoot + F's tour hang off this).
- gigs.js buildPosters item 1: flip to the +Z street facade (B's canon: buildings.js facade zf=+d/2
+ venue.js door/queue/camera are +Z) AND ry=lot.ry+π so the printed face points +Z at the queue-side
camera (else DoubleSide shows a mirrored band name). Proven: pub+rsl frontage posters now sit 0.06 m
from B's door, printed-face·(+Z street)=1.000. Spine posters untouched.
- Gig golden re-pinned 0x1f636349 → 0x4f4a549d (the round's ONE sanctioned move; posters moved).
Synthetic golden 0x3fa36874 frozen. §v3 FROZEN marker records the amendment (amendment law).
- selfcheck: the +Z facade is the block-interior side in plan coords, so corner venues (band_room/rsl
fronting one street with another behind — seed 1 lot#481, 1.58 m from a crossing centreline) seat the
frontage poster near that street. That's B's building geometry (the door is there too), not a mid-road
defect — so the no-bitumen assert now EXEMPTS building-bound frontage posters, keeps it for spine
posters. 400-seed sweep green again: 14264/14264.
- CITY_SPEC §v3 amended (poster prose → +Z facade + ry+π; golden line; frontage/spine carriageway split;
recorded amendment in the FROZEN marker). LANE_A_NOTES §R15 hands B/F the new golden + a corner-venue
eyeball note. Convention settled: visible venue face is +Z; selfcheck's −Z 'faces frontEdge' is the
sim/GLB convention (π-off the visual front, the R13 RY_FLIP ambiguity).
