Each successful JARM / HASSH / TCPfp probe fans out an
attacker.fingerprinted event; the probe family goes in event.type so a
single subscription covers all three. Payload carries the attacker IP,
port, and probe-specific hash — enough for the MazeNET live map to
render fingerprint info on observed attackers.
Lifts the thread-safe publisher helper out of the sniffer worker into
decnet/bus/publish.py so the prober (and every future worker with a
to_thread hot path) can reuse it without copy-pasting the
run_coroutine_threadsafe dance. Sniffer rewires onto the shared helper
in passing.
Adds ATTACKER_FINGERPRINTED as a new leaf — distinct from
ATTACKER_OBSERVED (correlator's first-sight signal) because an active
probe result is additional evidence about an already-observed attacker.
Note: the plan's decky.{id}.state realism-probe publish path is
deferred — the current prober fingerprints attackers, not decky
realism. Will revisit when realism probes exist.
Shared publish_safely helper at decnet/bus/publish.py so the nine
workers about to be wired into the bus don't each copy-paste the
"never raise back at the caller" contract. Mutator drops its private
copy and imports the canonical one.
topics.py gains the attacker.* hierarchy (observed, scored,
session.started, session.ended) and a system_health(worker) builder
for per-worker health heartbeats — both prerequisites for the worker
rollout under DEBT-031.
