-**Status:** OPEN — **WORKAROUND in place (sphere-overlap stickiness, commit `4ca3596`). M1.5 scope (A6.P4) — workaround removal after underlying push-back fix.** User-visible symptom resolved 2026-05-20; root cause still to investigate.
+**Status:** DONE — the `4ca3596` sphere-overlap stickiness workaround was
+REMOVED in T6/BR-7: it had become dead code (its only caller path was the
+cache-null test fallback in `ResolveCellId`), and the retail mechanism that
+owns doorway hysteresis is the ordered-pick (current cell at CELLARRAY
+index 0, interior-wins-break — `BuildCellSetAndPickContaining`, the
+collide-then-pick advance), which production has used since the membership
+rewrite. The ping-pong's original harm (outdoor ticks bypassing indoor BSP)
+is structurally gone under the per-cell query: both classifications collide
+the same per-cell lists at the threshold.
 **Severity:** HIGH (workaround unblocks indoor visibility for M1.5 baseline; M1.5 acceptance requires the proper fix)

+tick-22760 (outdoor block invariant), the flipped door apparatus, and the
