From d7af2cab972d349c7f2cce39a7a9ced53e100b47 Mon Sep 17 00:00:00 2001 From: Fr0zka Date: Tue, 22 Sep 2026 16:23:20 +0200 Subject: [PATCH] fix(collision gate): hold the fall, not the player; add voxel.CollisionGate switch The owner could not do speed runs: the gate stopped the whole pawn whenever streaming fell behind. Measured at 6000 cm/s on 0dd45ca: one 18.9 ms hold followed by terminal non-resume, 4.522 m of a 120 m route. The gate now cancels only downward motion into unresolved ground, keeps horizontal velocity and player control, ignores air and out-of-layout tiles, and requests a blocking support tile at high priority. voxel.CollisionGate (default 1) disables the safeguard for stress runs; it is snapshotted at start-up. After: stress run PASS -- 4 holds, 1.881924 s total, full_stops=0, 139.947 m of 120 m. Strate crossing PASS with pending_floor_overlap=0 and the lower strate reached. Static perf sanity PASS. Verification budget kept small on purpose (no suite, no exports): the owner's complaint was that a one-line request triggered a thousand tests. Known, NOT fixed here: the surface-fall repro fails as surface_ground_timeout -- the pawn now lands, but on top of the authored (0,0) entry at Z=799.5 cm instead of dropping to its floor at -150 cm. The gate has released by then; this looks like the entry opening being capped, i.e. the owner's 'surface generation is bugged'. Next round.
