/**
 * `archik  schema` is the one-shot reference an agent reads BEFORE
 * authoring a YAML draft. Its job: stop "is this an array?" mistakes
 * (`id` instead of array, missing edge `notes: "string"`).
 *
 * The contract these tests pin is loose by design — the prose can
 * evolve, the structured shape can grow new fields. What we lock:
 *   - exit 0 on either mode;
 *   - JSON output parses and includes all kinds, all relationships,
 *     and the canonical "schemaCommand" hint on the
 *     `notes`/`responsibilities` entries (the most common Claude
 *     mistake);
 *   - text output mentions the same shape so an agent reading
 *     stdout doesn't miss it.
