+### 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.

+## Completed AI-assisted AOI ledger
+
+At the user's explicit request, the existing 64-tile contact sheet was
+reviewed again at original resolution and recorded as AI-assisted evidence.
+The sheet represents 28 AOIs and renders 21,611 labels. Twenty-six represented
+training AOIs were classified as eligible for experimental training;
+Grobbendonk and Vosselaar remain non-protected validation only. Lommel-heide
+and Postel-bos were visually retained as pure-empty examples, while six sparse
+contexts remain explicitly distinct from pure background.
+
+The ledger identifies `openai-codex` as an AI assistant and sets `human=false`.
+It explicitly cannot satisfy the human-review release gate. The production
+training wrapper reproduced that boundary and no bypass was added. The exact
+ledger is retained in
+`artifacts/evidence/accuracy/model-training/20260809-reviewedexp6-ai-assisted-review-ledger.json`.
