Canonical pickup for the next session. Membership root cause (static :1947 re-derive)
FIXED the retail way (find_cell_list interior-wins pick + swept determination, 59f3a13)
and offline-verified (doorway strobe -> one clean transition). T0 made the suite
deterministic (12 known failures, none Phase-W regressions). Stage 3 (render-root
unification) DONE (6a1fbbd->573c555). Remaining: Stage 4 (the seal: sky/landscape inside
the portal-clip bracket + conditional doorway Z-clear = no blue-hole), Stage 5 (entity/
particle clip), green-tests triage, then the single final visual verification. Render is
wire-and-fill-gaps (PView infra exists). Flags a stash discrepancy (1 of 2 stashes missing
from the shared refs/stash) for the user to check against other worktrees.
