Three iterations of the Daikoku PA ramps never read as a real
interchange. Measured why, rather than tuning further:
* the entry and exit decks INTERSECTED -- 2547 sample pairs within
30 studs horizontally at <12 studs dY, worst case 0.5 studs apart
at dY=0.0. On screen that is the bowtie tangle of white rails.
* both real Daikoku ramps turn the SAME way (clockwise; the guide
video says "right, right"). This build mirrored them into each
other.
* the real arc wraps OUTSIDE the lot and forms its north/east
boundary. This build cut across the apron interior.
Gated behind BUILD_PA_RAMPS=false rather than deleted -- the radius
was already correct (470 studs vs an OSM-measured mean of 469) and
the merge lands tangent at 0.1-0.2 deg divergence. Both worth keeping.
Also removed two leftovers that would have outlived the ramps:
* rampOpen punched holes in the mainline's outer parapet, railing
and kill wall for ramps that no longer exist -- a barrier gap with
a drop behind it. Sealed via RAMP_EDGE_OPENINGS=false. Verified:
Barrier/EdgeRail/KillWall = 1646 each = 823 samples x 2 edges,
0 road samples without a guard within 90 studs.
* gore zebra hatching painted 1024 bars + 64 boundary lines marking
a junction that is not there. Sealed via RAMP_GORE_MARKINGS=false.
Verified after a cache-busting fresh rebuild (Studio's require() cache
otherwise serves the previous map and reports a false pass):
parts 22628 -> 15988
all ramp part classes = 0
Road = 823 (unchanged), spawn pad + PASpawn intact
clip probe TRUSTWORTHY (control +11/-0), CLIPPING=0
Research and rebuild spec kept for when this is revisited:
reference/ramps/BUILD_SPEC.md, INDEX.md (10 CC-licensed Commons
photos), docs/daikoku-reference-spec.md (OSM circle fits).
