The tower's twelve ROUTE_10 rows are `gabled_block_6x6` tile for tile --
the artist drew the top of the tower as an ordinary six-cell block -- so
that template matched at (24,132) and stood a whole second building
behind it. Templates were matched and stamped independently, with
nothing stopping two grids claiming one drawing.
Placement is now first-claim-wins: a template never stamps into cells
another already claimed, which makes the list order the priority order.
The tower's own two templates move to the front so they take those
cells first.
Also corrects the split: the Route 10 half is TWELVE rows, not eight --
the 64px purple roof band plus two window courses -- so topRows and the
claimOnly twin now carry all of it, and the model is the complete
twenty-row drawing (96px facade under a real 64px roof). Both templates
verified to place exactly once world-wide.
The mound probe gains a MOUND_LEVEL knob; the low rungs are where this
was visible.
The tower's drawing straddles the map boundary -- roof band and top
window courses in Route 10's last rows, the rest in Lavender -- so each
map folded its half upright alone: two half-buildings, Lavender's under
a fabricated yellow cap.
Buildings templates gain `topRows`: drawing rows composited ABOVE the
matched grid, for a drawing no single map holds. The model is built
from the complete 16-row artwork (96px facade under the real 32px
purple band) while placement still matches only the on-map rows; depth
now derives from the matched footprint rather than sprite height,
identical for every whole-drawing template. A `claimOnly` twin template
claims Route 10's roof rows and stamps nothing, so the top half no
longer also stands as its own building. Both templates verified to
place exactly once, world-wide, at the intended coordinates.
A body-anchored building's eave juts frontEave voxels past the map
boundary; the neighbour-body mask read that overhang as a ring scrap
and opened the roof rim into the sky from across the seam. Building
placements only scan the body, so their quads now carry an `own` flag
the edge keep-rules never touch.
