Live retail cdb trace (tools/cdb/cellar-corner-escape.cdb) of the Holtburg cottage cellar-top corner decodes the ground truth: retail escapes by step_sphere_up->step_up (196x vs 38 near-misses), transitioning the contact plane from the ramp (N.z=0.78) onto the flat cottage floor (N.z=1.0, 76 landings). acdream slides at the lip and never makes that ramp->floor transition -> the intermittent cellar wedge. So the remaining cellar bug is the #98-core step-up-onto-cottage-floor (DoStepDown / step_sphere_down / find_walkable), which the shipped B1 (abbd761) + slide_sphere (0935a31) fixes got close to but didn't finish. Door still blocks; generic step-up climbs; cellar went always-stuck -> works-mostly. Next (handoff doc): instrument acdream's OWN corner path (does step_up fire at the lip and fail to land on the cottage floor?) before porting the lip-climb -- no guessing (#98 saga rule).

$$ Cellar-top corner-escape capture — 2026-06-04 (P2 cellar wedge)
|
|
$$
|
|
$$ Q: at the cellar-top corner, the acdream player (on the ramp, pushing +Y)
|
|
$$ wedges against a -Y wall (head-sphere near-miss -> slide, oscillates, no
|
|
$$ net +Y). Does RETAIL escape by STEPPING UP over the lip, or by SLIDING,
|
|
$$ and is the near-miss a HEAD (neg_step_up=0) or FOOT (neg_step_up=1) hit?
|
|
$$ That decides whether the fix is slide-convergence vs step-up-at-the-lip.
|
|
$$
|
|
$$ Unique (non-overloaded) symbols only -> robust counts + key args:
|
|
$$ BPA CTransition::step_up(this, Vector3* normal) step-up ATTEMPT
|
|
$$ BPB BSPTREE::step_sphere_up(this@ecx, CTransition*, V3*) step-up DISPATCH
|
|
$$ BPC SPHEREPATH::set_neg_poly_hit(this, int negStepUp, V3* n)
|
|
$$ negStepUp 0=head(slide) 1=foot(step-up); also logs n
|
|
$$ BPD COLLISIONINFO::set_contact_plane(this, Plane*, isWater)
|
|
$$ landing signal: N.z ~1 = cottage floor (escaped), ~0.7 = ramp
|
|
$$
|
|
$$ thiscall: ecx=this; args [esp+4],[esp+8],... CSphere center: x+0 y+4 z+8 r+0xc
|
|
$$ Plane (set_contact_plane arg): N.x+0 N.y+4 N.z+8 d+0xc
|
|
$$ Floats logged as 32-bit hex (dwo + %08X); decode with tools/cdb/decode_retail_hex.py
|
|
$$
|
|
$$ Threshold 30000 hits across A+B+C (auto-detach via qd). BPD unbounded.
|
|
$$ Walk up the cellar stairs into the corner and let it wedge once or twice;
|
|
$$ the wedge generates the hits, so 30K auto-detaches within an attempt or two.
