--[[
	diag_editstate.luau -- read CarManager in the EDIT datamodel.

	This is the datamodel that PERSISTS (unlike Play, which is a sandbox that
	is discarded on stop -- the thing that silently ate every previous push).

	Purpose: capture a BEFORE snapshot so that after Rojo connects we can prove
	the sync actually replaced the source, rather than assuming it did. Records
	length and the two markers unique to the current fixes:

	  SHELL_YAW_OVERRIDE -> facing fix for hatch_junk / hyper_x   (NEW, x3 in src)
	  bestVol            -> pre-existing var, NOT a freshness signal (x6 in src)

	Note bestVol existed in the old code too (git HEAD line 479), so it proves
	nothing on its own -- SHELL_YAW_OVERRIDE is the real discriminator.
	Disk source is 41650 bytes; anything at 30631 is the old pre-fix version.
