Rework the PA junction to match the reference drawing: yellow = PA -> highway (entry), red = highway -> PA (exit). Entry and exit swap sides (entry now EAST, exit WEST) and both trunks hug the PA perimeter instead of running concentric spirals. The simplification: both carriageways sit at the same deck level, adjacent, so the median opening IS the far-side access path. The under-deck crossing and merge runs are deleted outright -- 8 runs collapse to 4, and the girder-soffit ceiling logic that constrained the crossing goes with them. Part count 24,210 -> 21,691. The median opening is now load-bearing rather than cosmetic (it is the only route from the far carriageway to the ramps), so it widens from 6 to 9 samples per junction. Orientation is a single flip-able constant (ORIENT) so a mirrored result is a one-line correction, not a rewrite. Measured on the built map (not asserted): - 600 entry + 600 exit ramp parts - max grade 8.00% / 8.27%, under the 9% limit - 0 collisions with piers/masts/girders (558 structural parts) - segment continuity <= 2.5 studs; trunk->merge handoff <= 1.7 studs - merge lands at dY 0.0 (exact deck level), 33 studs lateral - median open at junctions: 0 parts vs. control ~7 on plain mainline Two traps worth recording, both caught by controls: 1. Studio's require() cache silently rebuilt STALE code. The first "passing" build reported 17,575 parts and zero ramps, and the map contained PAOffRamp/PAOnRamp parts whose names exist nowhere in the current source. Every measurement taken before this was describing an old map. Added tools/rebuild_fresh.luau, which clones the module to bust the cache; use it rather than requiring MapBuilder directly. 2. A reported "median never opens" bug was a bad probe, not a defect. It counted `Barrier` (the outer edge parapet, which must NEVER open) instead of `Median_<i>`. Re-run against the right name: control 7, junctions 0. Both were only visible because the probes carry controls -- a 0-hit result with no control is vacuous. The verification harnesses are kept in tools/ with their controls built in.
