From eb47efdec9e0edceab45510ff63ce621192668ca Mon Sep 17 00:00:00 2001 From: Fr0zka Date: Sat, 5 Sep 2026 12:33:58 +0200 Subject: [PATCH] feat(measure): a player does not fit. The law was passing impossible routes. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Jahni walked composed strates for the first time: "'maze' is way too tight tunnel radius wise, i can't enter nor anything". The candidates he could not enter were the ones our metrics ranked BEST -- Maze had the highest walkable fraction (.285) and highest connected surface (.99) of all eight. ⭐ THE HEADLINE, AND IT IS BAD NEWS WORTH HAVING: old arrival->departure law passing on 7 of 8 candidates player-fit-restricted law CONNECTED ON 0 OF 8 **The primordial law has been passing on routes no player fits through.** Every "the world is traversable" claim in this project measured air, not passage. Player-fit fraction across the eight showcase candidates ranges .0000 (FloatingIslands -- literally zero) to .0117. The season composer now returns 0 survivors for 6 required slots, and the showcase gate rejects 8 of 8. That is the correct outcome. The gate is not tuned to a threshold; it requires a resolved player-fit volume and a connected player-fit route. Capsule confirmed by Jahni as the base ACharacter: 34 cm radius, 88 cm half-height = 1.36 voxels radius, 7.04 tall. Named constant with the derivation beside it. Two traps avoided, both of which would have produced confident nonsense: - THE COARSE GRID CANNOT RESOLVE A PLAYER. SampleStep 4 makes a cell 4 voxels, ~3x the player's radius, so fit is below the resolution of every metric built so far -- which is exactly why nothing flagged an impassable maze. Fit runs on step 1 and REFUSES (bPlayerFitResolved=false + reason) when the step is too coarse. - Manhattan distance >= Euclidean, so reusing the existing transform for clearance would OVERESTIMATE free space and report fits that do not exist. Clearance uses a separate Chebyshev transform; Manhattan stays only on the legacy feature-scale metric. ⚠️ MY ROUGHNESS HYPOTHESIS WAS WRONG, and Codex disproved it rather than confirming it. Forcing SurfaceRoughness=0 on the Maze moved PlayerFit .0105 -> .0138 and the restricted law stayed NotConnected. Minimum corridor clearance is 1.00 voxel (25 cm) with or without roughness -- the corridors are simply too tight for a 34 cm capsule, full stop. Roughness IS still a real pinch risk where reach exceeds corridor radius: Underwater 2.21x, FlatPlain 2.31x, CrystalChamber 1.81x, TunnelNetwork 1.44x on corridors, VerticalShafts 1.30x on connectors. The 5.625-voxel default bound stays dangerous. Islands measured, not changed (feel is Jahni's call): 0/2 touch either seal, median clear gap 47.8 above / 9.0 below -- but effective radius spans 27-258 voxels at H=128 with ThicknessRatio .546, so the worst case has zero guaranteed separation. Recommendation recorded: radius back to 18-42, StrateHeightInChunks 4 -> 6, ThicknessRatio <= .40. Build clean, 30 succeeded / 0 failed, verified in the namespace log.
