Eight geometric assertions against the built map, runnable from Linux over
the Studio MCP bridge. Each check tests the world that exists rather than
trusting that a build reported success.
Check 1 is the important one: it fresh-requires Circuit and asserts
823/200/474. Studio caches ModuleScripts, so a stale Circuit will happily
build a plausible-looking map of the wrong circuit -- which is exactly what
happened before. The shape checks are meaningless without it.
Found and fixed while writing this: a Sound with a doubled rbxassetid://
prefix in the imported CarLibrary chassis.
Probe note: pillar tops are flush with the deck by design (0.00 clearance),
so the car-envelope probe must ride fully above the road surface or it
reports its own supports as intrusions.
