+The executable derives its action context from `SIGINT` and `SIGTERM` and
+passes it to `Runner.Run`. Signal cancellation therefore uses the same action,
+summary, and error paths as other context cancellation.

 For each `generate` or `run` action, `Runner` constructs one project-owned Promptkit executor after configuration loads. It captures an absolute working directory, resolves only a relative explicit output override against it, and passes the working directory, loaded configuration, resolved override, and any `--llm-debug-dir` request to the app. The raw configured fallback remains in the configuration for app-owned destination selection. `run` uses the same explicit-resolution rule for `--out-dir`.
 
 The CLI dispatches only generation and batch actions. It has no persisted-run or inspection dispatch. Summaries include report identity, status, output path, effective profile/backend/model, source warnings, validation, requested debug path, and notification result when available. They intentionally exclude prompt input, raw generated text, render context, endpoints, credentials, and full Distributor payloads. A failed action with a partial result still emits its safe summary before its error is returned.
