+## Genuine CPU functional proofs
+
+The internal v3 worker SHA is
+`299c1b784eac46b31d228453a399e1378f327fc9ed5e34ab950c804da33e433a`;
+its inventory SHA is
+`4904995685a5e55e0a790d9cc409dc8458e39c30cda4097c5d70bf75cb5c976c`.
+English/German tests relocated the worker and real models to paths containing
+`München`, `測試` and `🚀`. Each repeated recognition returned stable bounded
+passages, and the second call reported zero additional model-load time. These
+checks selected `Auto` in the Rust client with `SEARCHI_FORCE_CPU=1`, so native
+execution was explicitly CPU. They do not validate dynamic acceleration loading.
+
+The actual service lifecycle test passed in 113.50 seconds. Adding recognition,
+an injected optional failure on policy upgrade, and a genuine retry all retained
+byte-identical raw Google vectors with zero additional raw-audio encodes.
+Recognized results, exact verified excerpts, stable policy/source retry identity
+and the retained Google query reader were checked. This uses a query derived
+from recognition to test the contract; it is not an independent relevance score.
+Raw log `.searchi/qa/service-speech-google-cpu-v3.log`: 1292 bytes, SHA
