 * Outbound half of the two-way platform sync (COR-1174). Inbound needs no seam:

 * Echo prevention is three layers: `source_key` idempotency, the fan-out
 * skipping a comment's own platform, and the host's bot-sender check for the
 * window between a publish and its `attachExternalSource` write-back.
