Tests added: - physics_materials.rs: 15 tests (fire, smoke, steam, grass, dirt, bone, wood, stone, lava temp) - physics_interactions.rs: 12 tests (lava+water, fire spread, acid interactions, sand+water) - player_controls.rs: 12 tests (move L/R, jump, double jump, rapid input, wait, continuous) - collision_robust.rs: 10 tests (walls, ceiling, sliding, corridor, slope, dirt wall, unstick) - ragdoll_death.rs: 7 tests (death transition, ragdoll fall, progressive damage, corpse) - determinism.rs: 8 tests (same seed, replay exact, replay partial, recording, 100-tick) - edge_cases.rs: 19 tests (boundary, stress 20 goblins, fill/clear/paint, gravity, camera) - 6 new JSON scenarios (fire chain, lava pool, sand bury, entity fall, steam, acid wall) Fixes: - AABB resolve_aabb_y: add vertical overlap check (was pushing player down when jumping) - AABB resolve_aabb_x: velocity-aware resolution (player was stuck against walls) - check_on_ground: use fractional position check (was always true) - jump_force 1.5 (was 0.8) for 27-body entity - Gravity read from self.verlet (was from clone, SetGravity didn't work) - u8 overflow in lava color (saturating_add) 109 Rust tests, 14 JSON scenarios, 0 warnings, 0 failures
