The prior localization (step-up CLIMB) was disproven by an ITestOutputHelper
capture. Records the real root cause (A6.P4 near-miss missing retail's
num_sphere>1 gate, fixed in abbd761), that the door blocks faithfully with a
real floor, and that the remaining red tests are separate (apparatus
synthetic-floor artifact, LiveCompare buggy-captures, D4 airborne) — not
simple "flip to green" targets. Next is the user visual gate.

P1 membership is DONE (proven to already match retail; the 0/11 was a cdb capture artifact;
merged + pushed). P2 root cause localized to BSP Path 5 grounded step-up: the Path 5 wrappers
(DoStepUp=retail step_up, DoStepDown=retail step_down) are verified faithful + reached; the
divergence is in the step-up CLIMB (find_walkable/step_sphere_down up-adjust when sp.StepUp=true).
- docs/research/2026-06-03-p2-door-stepup-handoff.md: canonical P2 pickup + fresh-session prompt +
DO-NOT-RETRY (the wrappers) + the tooling note (xunit swallows Console.WriteLine).
- master-plan §3: P1 marked DONE + the (a)-(d) deletes/unifications re-scoped to approval-gated
refactors of working code; P2 localization recorded.
- CLAUDE.md M1.5: dated 2026-06-03 pointer (P1 done, P2 active, render seam in P3/P4, pickup doc).
