The #182 CSphere port (96ae2740) failed its visual gate and introduced an
airborne "stuck in the falling animation" regression. A player-attributed retail
cdb trace (tools/cdb/retail-crowd-jump3.cdb) proved retail's LOCAL client fully
runs player-vs-creature collision (76 land_on_sphere, 188 COLLIDED, 130 SLID,
~78% OK, glides across) -- NOT server-authoritative (an earlier unfiltered
land_on_sphere=0 read was a false lead the attributed trace refuted).
acdream's same-repro capture: 50.9% OK, 22.4% stuck, 115 airborne-stuck. Root
divergence: retail CPhysicsObj::UpdateObjectInternal (0x005156b0, pc:283688) sets
cached_velocity = (resolved - old)/dt -- velocity from ACTUAL movement, so a
blocked jump collapses to ~0 -> gravity -> the player falls/glides. acdream
integrates velocity + reflects on collision (PlayerMovementController ~:1008-1069),
so the jump velocity (~18) persists against the creature -> hang.
Fix = verbatim rebuild of the per-frame player-physics loop (UpdateObjectInternal
chain), velocity model first, transition internals kept. Full design +
retail function inventory + the capture apparatus + retail target numbers:
docs/superpowers/specs/2026-07-07-player-physics-update-verbatim-rebuild-design.md.
Implementation deferred to a fresh session (user decision). Also files #183
(floating distant scenery, observed during testing). #182 stays as the base.
