Retail's OBJECTINFO::validate_walkable @0x0050d010 initializes its return slot to OK (0x0050d025) and assigns ADJUSTED only inside the below-plane guard, immediately after the push executes (0x0050d249). The guard-fail path — grounded, OnWalkable, plane too steep — jumps past the contact write, the push, and the assignment (0x0050d1b9 -> 0x0050d251): retail deliberately IGNORES the steep plane at primary validation so the insert proceeds, the step-down phase fails on the steep landing, and the edge family produces the per-tick lateral glide. ACE flattened this into an unconditional return Adjusted (ObjectInfo.cs:169) and we inherited it; our TransitionalInsert then retried the byte-identical Adjusted forever — the user's stop-instead-of-slide. Evidence chain: the user's retail observation (the axiom), the live cdb glide profile (edge_slide/cliff_slide 594 each in lockstep, step_up 0), the D0 implementer's correct STOP (fixtures reproduced the stuck fingerprint while faithfully executing the ACE-shaped reading — refuting the reading, not the code), and the capstone byte-decode both Opus reviewers re-derived independently, including the stack-slot frame arithmetic and every ret site's eax. The conformance fixture is the live topology: flat and steep terrain triangles sharing ONE cell's diagonal (a cell-boundary face does NOT reproduce the loop — the cell-scoped primary sample never validates a neighbour's triangle — and is pinned as supplementary). Sabotage: restoring the unconditional Adjusted reds the discriminator with the exact stuck position (0.325 m lateral, 28/30 stuck ticks vs 2.602 m / 14/30 fixed; reviewer B's independent five-angle table is monotone 10-85 degrees). Stuck ticks are counted from positions so the assertion survives the eventual probe strip. In-game glide gate PASSED 2026-08-08: "Well it works, we are sliding. I cant detect any speed change from retail." Filed alongside: #347 + AD-70 (our glide alternates arm/move at half retail's per-tick rate — retail redirects within the tick; next up by user direction), AD-71 (the guard's mutable WalkableAllowance operand vs retail's fixed is_valid_walkable global — now return-value-bearing), and the reviewers' named residuals in the #345 closure entry (placement-arm flip, other-cell coverage gap, EdgeSlide-less projectiles, ACE's server-side shared misport predicting remote drift-then-snap on steep terrain). The unported IsViewer arm of validate_walkable is noted in the D0 doc. Suite: clean-room complete solution 11,271 passed / 4 skipped / 0 failed; Core assembly re-run green after the review-driven test hardening. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |
