+## TEESimulator-RS v4.8.1: StrongBox Op Rejection Fix
+
+- **StrongBox op limit gate fix** — `trackAndEnforceOpLimit` was only called in the `Domain.KEY_ID` not-found path, so software-generated keys (found via `Domain.APP`) bypassed `STRONGBOX_MAX_CONCURRENT_OPS=4` entirely. DuckDetector's concurrent signing handles test created 24+ operations that all succeeded via LRU pruning instead of being rejected with `TOO_MANY_OPERATIONS (-29)`. Now enforced for all StrongBox createOperation paths.
