+# Gate B Results — 2026-09-07 pass 6
+
+Evidence collected on gate-b @ `2586fdb` (cutout-on-checkerboard fix `83171fa`). LIVE run against `https://100.64.0.9/`.
+
+Ty SoT for mask preview: slab cutout on checkerboard. Green overlay / avgAlpha is not a pass. Pass5 UI-MASK-1 (green wash metrics) is superseded for that claim.
+
+Proxy and API cases were not re-run (local vitest and pytest env missing). This table is the UI-MASK correction only.
+
+| Case | What this proves (mill-owner) | Evidence class | Result | Evidence | Blocker |
+|---|---|---|---|---|---|
+| UI-MASK-1 | The slab stays visible as a cutout. Removed background is checkerboard, not a green wash. | e2e | pass | `test-results/gate-b-2026-09-07-pass6/live-mask-bvt.txt:4,7` + `live-mask-ux/mask-overlay-live.png` (slab=1200, checker=4800, greenTint=0) | |
+| UI-MASK-2 | Knobs respond without a multi-second lag | e2e | pass | `test-results/gate-b-2026-09-07-pass6/live-mask-bvt.txt:8-10` (sensitivity 36ms, edge offset 17ms) | |
+| UI-MASK-3 | Sheet mode does not mark the whole frame as slab | e2e | pass | `test-results/gate-b-2026-09-07-pass6/live-mask-bvt.txt:11-13` (slab fraction 0.200) | |
+| UI-MASK-LAN | Phone/iPad mask fundamentals on the LAN host | human-walk | blocked | — | Ty walk. No LAN device evidence. |
+| OPS-1 | HTTPS health on the deployed host | deploy | blocked | `test-results/gate-b-2026-09-07-pass6/health.txt` | curl to `https://100.64.0.9/api/health` timed out this pass. Not scored as app fail. Not a pass. |
+
+**Counts:** pass = 3, fail = 0, blocked = 2. Total rows = 5.
+
+**Gate B is not green.** LAN/iPad human-walk is still open. TV product-state still needs real PNGs. Full UAT is unproven. A live-host cutout check on Tailscale is not Gate ready.
