fix: recover eligible model GPU routes

README.md

@@ -451,11 +451,24 @@ routes per model, preserving successful-route and queue ordering without
 discarding capacity on lower-ranked GPUs when the preferred tranche cannot run
 the model.
 
+Version `2026.09.20.1` corrects the community verification precheck: an exact
+model/GPU route marked `未验证` with no records is eligible, while `已验证`, `验证中`,
+and unknown states stay blocked. A `验证失败` route may use a different framework
+only when every previous record explicitly failed and names its framework; the
+fresh check before submission rejects any framework that has already failed on
+that GPU. The official framework evidence and deterministic preflight gates
+still apply. When recent-update discovery is exhausted, a bounded 500-model
+download-ranked ModelScope scan checks a rotating 200-row window of older
+popular models without exceeding the platform's 3,000-row pagination ceiling.
+Architecture history backfill now
+sends the date format accepted by ModelHub. The full-repository-size OOM rule is
+unchanged because ModelHub's own preflight uses that size.
