Logan CusanoandClaude Sonnet 5 ca1d8fbdae correlator: gate LLM-orphan against rules-new instead of escalating to tiebreak (#115)
CORRELATION_REVIEW_0907b.md measured that radio housekeeping (unit
check-ins, roll call, 10-8/10-98 clearings) is being promoted to
incidents. Every case reads corr_llm_action=orphan, corr_rules_action=new,
corr_consensus=tiebreak -> new: the cheap LLM correctly reads "not an
incident", the rules engine says `new` only because there is no incident to
link to, and the smart tiebreaker then sides with rules ~21/21. Reframing
the tiebreaker prompt (#116) did nothing. The fix is a consensus-logic gate,
not another prompt.

Fix 1 (routers/upload.py) - LLM-orphan gate in _correlate_with_consensus:
when the cheap LLM says `orphan` and the rules engine says `new` with NO
positive event signal, resolve to `orphan` and skip the tiebreak call
entirely. "No positive signal" = the rules corr_debug carries neither a
positive corr_path (unit-continuity / location / fast/disambig / fast/single)
nor a positive corr_fit_signal (unit_overlap / location_proximity). When it
does carry one, the existing escalation-to-tiebreak is kept so a genuine
event the LLM misreads as orphan still gets the second look. The resolved
outcome records corr_consensus="llm_orphan_gate" (greppable, distinct from
"tiebreak") and keeps corr_llm_reasoning / corr_rules_action /
corr_llm_action populated.

Fix 2 (incident_correlator.py) - tighten corr_path=location: the location
path linked on a bare sub-location_proximity_km (0.5 km) distance with no
unit or content check, which stitched a vehicle lockout to a station-restroom
slip and merged two different churches an hour apart. A location link now
requires unit overlap with the candidate OR a distance under a tighter bar
(_LOCATION_TIGHT_PROXIMITY_KM = 0.2 km). Pursuit incidents keep their
movement-speed-validated wide radius. A surviving location link now also
writes corr_fit_signal (unit_overlap | location_proximity), consistent with
Fix 1's positive-signal set.

Tests: new tests/test_consensus_gate.py (13 cases) - the gate resolves to
orphan without calling tiebreak on a no-signal disagreement; a unit_overlap /
location_proximity / unit-continuity / fast-disambig rules signal still
escalates; llm=link vs rules=new still escalates; the location path drops a
shared-area candidate with neither unit overlap nor tight proximity, links on
unit overlap, and links on tight proximity alone. Full c2-core suite
309 -> 322 passing.
