/**
 * hosting/wireOps — the ONE list of operations a request body's `op` may name.
 *
 * A hosting request is ordinarily a MESSAGE. Some are not: since 9.23 a body
 * carrying `{ op: 'artifact-head' | 'artifact-get', ref }` redeems a claim
 * ticket, and since 9.26 one carrying `{ op: 'session-list' }` or
 * `{ op: 'session-transcript', sessionId }` asks the verified caller's own
 * conversation history. Two DOMAINS now share one field. (`answer-account`
 * belongs to the artifact domain: it names a claim ticket, and its reader is
 * `readArtifactWireOp`.)
 *
 * That is exactly the shape where a grammar quietly forks. Each domain has its
 * own reader (`readArtifactWireOp`, `readSessionWireOp`), each reader must
 * decline the other domain's ops without claiming them — and somebody has to
 * own "this is not an op anybody speaks", which is the refusal that keeps a
 * typo from becoming a conversation turn with a ref as its input.
 *
 * So the names live here, once, and both readers ask this module the two
 * questions they cannot answer alone: *is this somebody's op?* and *what do we
 * say when it is nobody's?* Either reader produces the same refusal, listing
 * the same operations, in the same words — so the answer never depends on which
 * dialect happened to call which reader first.
 */
