The 2026-08-26 downgrade rested on two numbers, and grouping the CollisionSet names by prefix dissolves both: - The 447 km "largest object" is rob_f002_cmesh, one of only FOUR rob_ meshes (44k-448k). That family is not hull size: rob_f001_bdy_cmesh measures 50179 and f001 is the player's own Delta Saber, whose disc record gives Size_Radius 10.0. A 50 km player fighter is impossible under every unit convention, so rob_ spans something else entirely and is not evidence about the world unit. - The "small" 133 m craft is small: rou_e010_cmesh = 133.2 is the 7th smallest of 78 rou_ meshes (median 636.2, max 9534.9). Against its own family, the game calling e010 small AGREES with the metre. Measured this run: the 500 km box is a cube of exactly 500000.0 units on every axis (+-250000), and the second box mesh is exactly 100000.0 -- the same ruler. Independent dynamic confirmation already in the corpus (flight-speed-law.md): 443.6 world units per wall-second, mission clock 1.26x wall, so 352 units per game-second against a HUD reading of 350.
