@ -343,6 +343,15 @@ GPU/frame-time and ordinary-process memory comparison remains a physical-
display measurement, not a Slice-I correctness blocker. Evidence:
[`../research/2026-07-25-slice-i7-closeout.md`](../research/2026-07-25-slice-i7-closeout.md).
**Corrective gate 2026-07-26.** Later connected house/dungeon testing exposed
one I7 consumer omission: `CEnvCell::find_transit_cells` still required the
deleted parsed portal-polygon dictionary, even though the prepared topology
and polygon table retained the exact same plane. The production consumer now
uses that direct prepared index. Synthetic graph-free tests and the captured
Holtburg cottage camera path prove identical graph/prepared results; no
package rebake or parsed-graph restoration is needed. Evidence:
[`../research/2026-07-26-prepared-indoor-transit-regression.md`](../research/2026-07-26-prepared-indoor-transit-regression.md).
