- * Convergence is not a static config invariant: provider generation caps can be

- * of unpredictable size. The backend instead enforces convergence dynamically:
- * each committed summary must be smaller than the content it shadows, and

  * @param config - the raw, unresolved backend config.
  * @returns the validated config with `auto` and `charsPerToken` defaulted.
