Interface surface 2 partial [cli] --help documents every option (at least 90% of options have help text).
Can another program use it through a documented, machine-readable surface?

- next: [library] L2 The public API is delimited (__all__, an exports map, exported identifiers). (no __all__/exports defining the public API)

Events n/a Not applicable: no service and no long-running CLI mode (batch CLIs, libraries and desktop apps have no events).
Can others react to state changes without polling?
Identity n/a Not applicable: uses no credentials and has no service surface.
Can a machine act with its own revocable, least-privilege identity?
Data portability n/a Not applicable: owns no persistent data.
Can its data get in and out, in bulk, in open formats, with an explicit schema?
Agent ergonomics 1 ad hoc [cli] Never blocks on a prompt when stdin is not a TTY.
Can an automated caller use it without guessing, and recover from failure?
- next: [cli] L2 Data on stdout, diagnostics on stderr, non-zero exit on failure. (diagnostics aren't written to stderr)
- next: [library] L1 Errors are specific exception types, and library code never calls sys.exit. (no exception classes)
