The campaign clusterer worker mirrors the identity-side worker shell (bus connect, heartbeat, control listener, slow-tick fallback) but wakes on identity.> instead of attacker.> — campaign-level work is gated on identity-layer changes, not raw observations. The connected-components implementation reads identities via list_identities_for_clustering, projects them with from_identity_row, runs union-find over combined_campaign_weight, writes campaigns rows, sets attacker_identities.campaign_id, and runs the same revocable- merge pass as the identity layer (a merged-out campaign whose identities no longer co-cluster with the winner gets revoked). Bus: adds campaign.> family (formed / identity.assigned / merged / unmerged) plus the cross-family identity.campaign.assigned so existing identity-stream subscribers see the badge update without having to subscribe to campaign.>. Wiki Service-Bus.md updated in wiki-checkout in the same wave per the project's bus-signals discipline. CLI: decnet campaign-clusterer registered as master-only via MASTER_ONLY_COMMANDS; --poll-interval / --daemon mirror the identity clusterer command surface.
