+## 35. S5-c5 landing, review closeout, and lead graphical smoke — 2026-09-05
+
+**CLOSED AND LANDED; GRAPHICAL PASS IS PROVISIONAL PENDING OWNER
+INSPECTION.** The reviewed implementation stack in `s5-c5-openai-impl` is
+`36bea55f337c010683263a2eb315514c47121e9f` ->
+`2886091aa92f62ceec8c16d4fd5b2dd6056eb5b8` ->
+`158656f0df3edd5e28ac3a9ed743f4c435e321f9`. It maps to the campaign stack
+`bf53e2ad6` -> `e625dc4e6` -> `1b7ee4e58` on top of contract
+`b77989c32`. The final campaign commit is
+`1b7ee4e58100b27a55063e0bd462f54c589b1d7e`.
+
+The deletion removes the callerless portal-BFS research graph and its tests,
+the complete Facility-stair instrumentation family, the obsolete renderer
+probe/output branches and hidden scratch, and the raw-GL diagnostic reader.
+The live `RetailFrameWalk`/`WalkFrameDriver`, `BeginWalkFrame`, outside-view
+reassembly, two FIFO lists/router/material/shader paths, typed walk transcript,
+frame profiler, terrain diagnostics, and
+`UnregisteredRenderMembershipCount` remain. Architecture and inventory now
+state one production graph; AP-19 is retired, AD-116 is amended, and
+AP-238--AP-243 remain active.
+
+Sequential review closed in three passes. Retail/deletion pass 1/10 returned
+PASS with no finding after independently rechecking the named functions and
+the paired binary/PDB identity. Production/gate-honesty pass 2/10 found one
+MINOR test-only non-vacuity hole: the unique-owner reflection scan omitted
+static fields. Fix round 1 added `BindingFlags.Static`. The lead reproduced
+both required static-owner mutations and their intended first failures, then
+restored them exactly. Production re-review pass 3/10 returned PASS with no
+remaining finding; the production source tree was unchanged by the fix.
+
+Exact reviewed-tip evidence is hermetic 16,921 passed / 0 failed / 0 skipped,
+canonical InstalledDat 368 passed / the accepted nine failures / one accepted
+look-in skip, and both manifests 30/30. Fresh campaign-tip verification passed
+Release at 0 warnings / 0 errors, App focused 146/146, and Core focused 8/8.
+The campaign tree was clean before the graphical gate.
+
+The first smoke attempt is excluded as environment preflight evidence. It
+opened the default machine-local `acdream.pak`, rejected recipe 8 against the
+recipe-10 client, emitted no PNG, exited with the .NET unhandled-exception code,
+and left no client. Log:
+`logs/selfgate-20260905-051948-s5-c5-landed`. No renderer assertion was
+reached. The lead then ran the repository's validated transactional bake to a
+new path, leaving the recipe-8 package untouched. Recipe-10 output:
+2,237,865 keys, zero failures, 597,482,264 bytes, SHA-256
+`4E0FA6C589ECE12E13099A56385077964961EC52F888BC9161C6F5D34829B59B`.
+
+The one corrected smoke run began with ACE listening on UDP 9000, zero client
+processes, a clean campaign tree, and the already-green Release binary. It ran
+`tools/overhaul-selfgate/route.txt` once against the new package, exited 0,
+confirmed graceful logout, and left zero client processes. The log contains no
+crash, invariant failure, device-loss/screenshot failure, or deleted probe
+prefix. Exact evidence root:
+`logs/selfgate-20260905-052130-s5-c5-landed-v10`. PNGs:
+
+- `artifacts/screenshots/00-login.png`;
+- `artifacts/screenshots/01-cathedral-stairs.png`;
+- `artifacts/screenshots/02-facility-stairs.png`;
+- `artifacts/screenshots/03-holtburg-house.png`; and
+- `artifacts/screenshots/04-holtburg-terrain-leak.png`.
+
+Lead original-resolution inspection and comparison with
+`logs/selfgate-20260905-020703-s5c4-onepass-detail` found the same intact
+cathedral, Facility, house-portal, and outdoor-terrain geometry; only authored
+time/weather changed. Verdict: **PASS, provisional until the owner inspects
+the PNGs.** S5-c5 is closed. S5 automated/performance closeout and G4 remain;
+never merge to `main` before G4.
