 * `ArtifactRefusalReason`, `ArtifactSweepReason`) into words a non-engineer
 * reads. Keeping them here means a new union member is one edit in one place —
 * and the exhaustive `Record<Union, string>` types below make the compiler,
 * not a reviewer, the thing that catches the omission. (`PermissionCapability`
 * taught the repo what two drifting copies of one union cost.)
 *
 * LAW, inherited from the artifact events themselves: META ONLY. These
 * sentences may say how BIG a payload was and what KIND it was; they never
 * carry the payload, a digest, or a raw refusal `detail` string. A ref is an
 * identifier, not prose — it belongs in DETAILS, so no phrase here prints one.
 *
 * Not exported from any barrel: this is prose plumbing for the commentary
 * engine, not public API.
