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

- unix.Gettid retrieves the caller thread ID matching a positive integer
- unix.Getpgrp retrieves process group identifier matching a positive integer
- unix.InotifyInit1 initializes an inotify instance returning a valid file descriptor
