# Subscribes to attacker.observation.> and, for each event, ensures a
# stub AttackerIdentity row, runs the per-ValueKind merger over the
# full identity-keyed observation series, upserts the derived state in
# attribution_state, and publishes attribution.profile.state_changed
# only on transition. Periodic tick (default 60s) fires
# attribution.profile.multi_actor_suspected when >= 2 primitives flag
# the same identity. Closes DEBT-051.
