MEASURED FIRST (pipeline/arcade_measure.mjs, over 5 seeds, off Lane A's own generatePlan):
the arcade is ONE 42.00 m x 5 m edge, 2 blocks, 16-17 shops (17 at the default seed), frontage
3.00-4.94 m (mean 3.87-4.05), depth 5.1-8.0 m, 4-11 of them two-storey. Walkable 5.00 m between
lot faces. AWNING_DEPTH 2.2 from each face means the two slabs already meet 0.60 m apart over the
centreline — the arcade IS roofed, and the roof is an accident.
⚠ AND THE POSTS ARE IN THE WRONG PLACE: buildings.js:643 puts them 2.00 m out from each lot face,
i.e. +/-0.50 m from the centreline — two rows of posts 1.00 m apart down a 5.00 m lane. No
collider, so it walks; it just reads as a colonnade planted in its own doorway. Lane B ask filed.
SHIPPED (all riding existing shared materials or stating their draw):
facade-shuttered 768x595 (the 1.29:1 arcade lot aspect, not the pool's 1.78:1) — the dead
tenant. +0 draws, +0 tris, 1 of the 14 FREE facade-atlas slots (22 of 36 used).
ground-arcade-floor 512^2 terrazzo — +1 draw TOWN-WIDE, +0 tris (the 504 m2 lane quad moves out
of footGeos). use:'arcade-floor' names a slot that does not exist yet, on purpose.
ground-arcade-roof 512^2 pressed-metal + wired glass — +1 draw in the 1-2 arcade chunks, +2 tris.
pipeline/seamless_tile.py: cut a regular-pattern skin to a whole number of its own periods instead
of feathering the joint. It has a guard, because on this pair the naive version made things WORSE:
the roof's x seam went 26.7 -> 8.3 (kept), the diffusion-drawn terrazzo floor is not periodic enough
to cut on (autocorr r=0.26) and 27.9 -> 31.9 was rejected and passed through. Recorded, not hidden.
manifest: facades 48->49, grounds 14->16. validate_manifest.py 0 errors, 0 warnings.
