narrativetrace-tooling

The free-tier tooling library, standard library only and zero network:

• The doctor — every check narrativetrace doctor runs, as pure functions over one read-only snapshot of a project (narrativetrace_tooling.doctor). The snapshot is built by the narrativetrace distribution, which owns the console script; the checks, the report and both renderings live here.
• The installer — the carrier reader, the project snapshot, the pure planners, the one writer and the renderers behind narrativetrace init / narrativetrace uninstall (narrativetrace_tooling.init).

Nothing here links against the runtime it diagnoses. This library never imports narrativetrace: it reads a project's configuration, source tree and rendered output as text, and it reads a skills carrier through importlib.metadata, which resolves an installed distribution's own files without importing it. The narrativetrace console script therefore sits above this library and depends on it, exactly as the Java port's CLI and Gradle plugin both embed narrativetrace-tooling and neither depends on the other.

Reached through the narrativetrace console script, not imported by consumers.
