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.

- unix.NsecToTimespec and unix.TimespecToNsec convert between nanoseconds and Timespec structs
- unix.Fstat retrieves file status metadata for an open file descriptor
- unix.Dup duplicates an open file descriptor returning a valid new descriptor
- unix.Umask sets and returns file mode creation mask
