+## 2026-08-09 - Explicit AI-assisted reviewedexp6 AOI ledger
+
+### Reviewed
+
+- Inspected the existing checksum-bound 64-tile contact sheet at original
+  resolution. It covers 28 AOIs, 21,611 rendered labels, dense urban, sparse
+  building context and pure-background examples.
+- Recorded a per-AOI machine-readable decision ledger with reviewer type
+  `ai_assistant`, `human=false`, the contact-sheet hash, sampled tile/label
+  counts, split roles and explicit roof-versus-GRB limitations.
+- Classified 26 represented training AOIs as experimental-training eligible;
+  kept Grobbendonk and Vosselaar validation-only. No AOI was represented as
+  human accepted or production release eligible.
+
+### Gate behavior
+
+- Confirmed that the governed training wrapper still requires accepted human
+  review and therefore does not accept this AI ledger as release evidence.
+- Did not add an override, fixture claim or synthetic reviewer identity. No
+  model training, activation or production redeploy followed from this review.
