The users final broken-state session (user-session-capture2.log,
standing in front of broken stairs) reports meshMissing=0 and
entSeen==entDrawn: the staircase is DRAWN WRONG, not missing. The
handoff records the 8 verified fixes shipped today (none was this bug),
the ranked hypothesis space (H-A hydration-time MeshRef corruption via
SetupMesh.Flatten identity fallback - predicts the barrel IS the
collapsed staircase; H-B Tier-1 partial-batch cache; H-C draw compose),
the decisive one-launch probe design, the polyClipFinish/cdstW port
spec for the climb strobes + top flap (read done, constant pinned), the
apparatus inventory, and the paste-ready pickup prompt.
