Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Contract
- libc.NewTLS initializes a valid thread-local storage context
- libc.CString creates a C-compatible null-terminated byte string and libc.GoString converts it back to a Go string
- libc.Xstrlen computes the string length of a C string correctly
- libc.Xstrcmp compares two C strings returning zero when identical and non-zero when differing
- libc.Xfree releases memory allocated by libc.CString
