Tonight's slice 6 session attempted 6 variations of placement-insert
bypass in Transition.FindEnvCollisions + Transition.DoStepUp. None
unstuck the player at the cellar ramp top despite mechanically firing
the bypass up to 72 times per session. Reverted all variants; nothing
shipped tonight beyond this handoff.
The hard finding: the placement-insert path is a SYMPTOM, not the
cause. Bypassing it (in 6 ways) doesn't make the sphere climb the
cellar ramp. The first-order question — why doesn't the sphere
progress UP the ramp via normal slope-walking? — wasn't addressed.
User's most actionable clue (not yet investigated): "outside ground
covers only the open path down into the cellar" → suggests a missing
hole in the outdoor terrain mesh over the cellar entry. That's a
terrain-generation bug, completely separate from BSPQuery.FindCollisions.
Handoff doc captures:
- The 3-session diagnosis evolution (each previous session's
confident diagnosis was wrong)
- All 6 slice-6 bypass variants tried and why each failed
- What we KNOW (data-confirmed) vs what we DON'T KNOW (open
questions)
- Specific next-step investigation order with terrain-mesh as #1
- Pickup prompt with strong "don't re-attempt placement-insert
bypass" guard
