 *   aidlc spec show [capability]          list capabilities, or one capability's requirements
 *   aidlc spec fold <instance> [--dry-run] merge the instance's `## Spec delta` into the corpus
 *
 * `aidlc transition` runs the same fold at an instance's completion moment;
 * this command is the earlier check (`--dry-run`) and the manual route
 * (design D4: no new gate before completion).
 *
 * Requirements: living-spec-corpus/AC-2, living-spec-corpus/AC-3,
 * living-spec-corpus/AC-4, living-spec-corpus/AC-15, living-spec-corpus/AC-16
