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
- x executes a process and returns stdout, stderr, and exitCode upon completion
- x supports command options including custom environment variables
- x returns non-zero exit codes when throwOnError is disabled
- x throws NonZeroExitError on non-zero exit code when throwOnError is enabled
- x pipes stdout to another process via the pipe method
- x yields stdout and stderr lines via async iteration
- x aborts a running process and sets aborted and killed flags when AbortSignal triggers
- x terminates a running process when kill method is invoked
- exec function alias behaves identically to x
