The artifact relay's route allowlist gains a subscriptions family, adding POST /subscribe/{slug} and POST /unsubscribe/{slug}. The artifact response schema now validates created_at against a strict ISO-8601 timestamp regex instead of accepting any non-empty string, and the summon-answer check returns a structured result that can carry a continuesReplyId.
