+### Genuine Google CPU package check
+
+The same harness optionally accepts `--model-dir` and `--embedding-worker`.
+It builds a new text-only semantic generation before starting hybrid MCP, with
+one CPU inference thread and `SEARCHI_FORCE_CPU=1`. The meaning query
+`ending a vendor relationship` must have no lexical matches, retrieve
+`contract.txt` as a semantic top result, and return the original cited passage.
+The report requires three actual document inference calls, not reused vectors.
+
+The normal archive worker and all 25 DLLs were extracted alongside its CLI.
+The Windows CPU check passed, including the optimized Python confirmation,
+2026-10-13. Generation 1 contains three chunks; the result reports hybrid mode
+and semantic availability. No test worker remained after completion; the
+installed desktop's independent query worker was retained.
+
+Ignored confirmed evidence:
+`.searchi/qa/agent-mcp-google-confirmed-20261013/report.json`, SHA-256
+`5d4bddbe73fdf9a30e19fece1622d0d3d9aefe4e2c19816d3df928ea78c3fde2`.
+This tiny document/code fixture proves real package inference and MCP citation
+integration. It does not establish broad relevance, media quality, GPU parity
+or native UI latency; semantic neighbours can still include irrelevant files.
