/// The row is written through <see cref="ISecretStore.ApplyReplicatedAsync"/>, not
/// <see cref="ISecretStore.UpsertAsync"/> — the hub must record the row <em>verbatim</em>, keeping
/// the originating node's revision and <c>updated_utc</c>. An upsert would stamp the hub's own
/// revision and timestamp, and the row would then look newer than the writer's own copy, so it
/// would bounce straight back on the next sync.
