- Set or clear a per-(strand, actor) watch subscription. Writes a current-value projection typed current result keyed by (strand_id, watcher_actor_id). Payload carries level in {mentions_only, participating, all, muted} (or null to clear, equivalent to mentions_only). Default invariant: payload.watcher_actor_id MUST equal envelope actor_id, unless writer holds ak.strand.watch.set.others. Cross-actor writes MUST be paired with a same-batch ak.audit.accessed event with access_kind=watch_set_others; the audit event carries semantic_refs[role=audit_pair] plus the suite-bearing paired_event_id pointing at the write, and derives its digest from that ID. The write MUST NOT reference the audit event (encoding.md §3.1 forbids mutual preimages). The watches Relation (actor --watches--> strand) is a derived projection of this typed current result, not a separate truth source — direct ak.relation.create relation_kind=watches MUST schema_violation. See models/strand-and-message.md §8.
