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.
The signal taxonomy for the campaign clusterer (next commit). Mirror
of the identity-layer module but with edge families that don't
translate 1:1: phase-handoff (load-bearing for F5 multi_operator —
the signal the identity-side fingerprint-disagreement veto deliberately
isn't), shared-infra (vetoed at identity level, primary positive
signal here), temporal-overlap (pairwise-relative — F7 invariance
preserved), cohort (weak supporting weight only).
Tier weights tuned so phase-handoff alone crosses threshold (F5),
shared-infra + temporal-overlap together cross (canonical co-op
pattern), and shared-infra + cohort together do NOT (F1
shared_wordlist's failure mode). The F7 time-shift invariant is
explicitly tested on every time-bearing edge and on the combined
weight.
