Logan CusanoandClaude Sonnet 5 dd426572fc correlator: fix consensus orphan-gate to test call substance, not empty corr_debug (#115)
The gate added in ca1d8fb checked rules_decision["corr_debug"] for a positive
signal, but that dict is empty at preview time for action=="new" (corr_path is
written at apply time). The check was always False, so the gate fired on real
events — replayed against corr_dump_9-7_pm.json it dropped ~36 linked calls
including a major "extinguishing fire", a moderate fire-alarm, geocoded calls
and pursuit updates.

Gate now runs against ctx (fully populated at preview time). It fires ONLY when
the call is substanceless: routine severity, no vehicle/geocode/tag, and no
incident already running on the same talkgroup. Any of those escalates to the
tiebreak instead. The substance predicate (has_event_substance) is factored out
of incident_correlator's creation gate and shared, so the two cannot diverge.

recorrelation_sweep: a call the gate parked gets a longer link-only retry budget
(10 vs 3) — the gate fires before any incident for the job exists, so the
substantive call that justifies linking can land after the standard ~6 min.
Still create_if_new=False.

incident_correlator location path: evaluate every in-radius candidate and link
the nearest that carries corroboration, instead of the first in an unsorted
`recent`. A unit-overlap location link is now tagged "location_unit_overlap" so
it stops merging into the fast path's bucket in the admin fit-signal histogram.

tests/test_consensus_gate.py: replaced the corr_debug-signal cases with ctx
substance cases (severity, coords, tags, vehicles, same-tg incident); added a
nearest-wins location test; the two location guard tests now assert they reach
the new guard. Full drb-c2-core suite 322 -> 325.
