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.
MIT-0

Contract
- unix.Uname populates Utsname with non-empty Sysname and Machine strings
- unix.Getpagesize returns a positive page size in bytes that is a power of two
- unix.Getpid and unix.Getppid return positive process identifiers
- unix.Sysinfo populates Sysinfo_t with non-zero total RAM and uptime
