"""Tests for meshai.central.incident_handler (v0.5.9).
Coverage:
Tomtom parsing + rendering (a/b/c/d):
(a) jam, accident, road_closed, lane_closed, road_works each render with
correct emoji + phrase + delay segment
(b) magnitude_of_delay == 0 events filtered at entrance
(c) delay == null events render WITHOUT the delay segment
(d) time_validity past/future events filtered
Per-incident change-detection (e-i):
(e) republish with no change -> drop silently, no new audit
(f) magnitude bump up -> Update
(g) delay double (>=2x) -> Update
(h) icon change -> Update
state_511 / itd_511 EventType branching (j-m):
(j) state_511_atis incident parses
(k) state_511_atis closure parses
(l) state_511_atis special_event parses (synthetic)
(m) itd_511 incident parses
Decoupled callback (n) and traffic_events UPSERT (o):
(n) cold-start scenario -- handler runs but callback never fires;
second pass still emits New: (not Update:)
(o) existing traffic_events row gets UPSERTed across passes
