  "security_notes": "Static review only — reads C/Cython/PyO3 extension source and build configuration to assess reference-ownership, buffer-protocol, exception-translation, and ABI/thread-safety correctness; never compiles, links, or runs the extension. A claim about an actual crash, leak, or free-threaded behavior is flagged as needing confirmation by compiling and running the extension. Never requests credentials or customer data.",
