$$ Retail cdb trace — does the cottage door block sphere at off-center inside-out approach?
$$ 2026-05-25
$$
$$ Three breakpoints with counters; auto-detach at 30K total events to avoid
$$ retail-session-lag → ACE timeout. Pattern from a6-probe.cdb (proven).
$$
$$ Question: when player walks from inside cottage to outside, off-center ~50cm,
$$ does retail's collision system FIRE (set_collide) at the corner where
$$ alcove east wall meets cottage north exterior wall? Or does it walk through
$$ silently like acdream does?
$$
$$ BP1: CPhysicsObj::FindObjCollisions — per-object collision test entry.
$$ BP2: CCylSphere::collides_with_sphere — cylinder shape hit test.
$$ BP3: SPHEREPATH::set_collide — collision RECORDED (the smoking gun).
$$    If BP3 fires often during inside-out walk: retail blocks.
$$    If BP3 silent: retail walks through too (= retail-faithful behavior).
