1. WZDx work zones: replace per-event broadcasting with a once-a-day
per-region count summary. Coalesce the upstream per-direction /
per-schedule-day fan-out into one row per physical zone
(road + lat3 + lon3 + sub_type); work zones are stored in
traffic_events but no longer per-event broadcast, while 511 crash /
closure / hazard incidents still broadcast live. A WZDxSummaryScheduler
emits one count line per coverage region once a day (default 07:00
America/Boise), routed via the region_routes 'roads' cells; work-zone
details are DM-queryable (build_work_zones_detail). New config:
wzdx.summary_enabled / summary_time / summary_tz.
2. FIRMS cold-start is now restart-safe: gate the silent-seed on the
persisted firms_pixels baseline being empty (first-ever run) instead of
an in-memory per-boot flag, so a restart no longer silently absorbs a
genuinely-new hotspot cluster.

Two bugs found running native adapters against real upstreams:
- env/wzdx.py: _select_feeds() called .strip() on the registry url field,
but Socrata "URL"-column values arrive as {"url": "..."} — crashed ALL
native WZDx discovery with AttributeError. Added _unwrap_url() (dict/str/
None-robust), applied to url/apiurl/feed_url.
- composer._context_segment: appended optional fields by key presence, so
cause: None (set by native road adapters) leaked literal "None" onto the
wire. Guard on value (cause/expires_at truthiness; containment_pct is-not-
None so 0% still renders). Legacy Mode-B path — golden tests unchanged.
+3 regression tests; golden/composer suites pass; full suite 10-failure
baseline (1685 passed).

New env/wzdx.py native adapter so meshai has a LOCAL source for the
work_zone category instead of Central-only. Keyless: discovers per-state
WZDx feeds from the FHWA registry (datahub.transportation.gov), filtered to
configured states (default [ID]), fetches each WZDx v4 GeoJSON feed, and
parses road_events into canonical work_zone Event.data.
- reuses central_normalizer._parse_wzdx_federal for identical field mapping
→ renders through the existing Phase-2 formatters/gating incident path
(no new formatter/gating); verified end-to-end to a valid work-zone wire
- stable external_id = {data_source_id}:{feature_id} for incident dedup
- registry cached 6h; per-feed failures logged + skipped (never crash)
- WZDxConfig extended (registry_url, registry_ttl, states); registered in
env/store.py; enabled=false + feed_source=native default (dormant until
turned on at the coordinated flip)
19 new tests; suite at the 10-failure baseline (1640 passed). Only env/wzdx.py
(new), env/store.py, config.py, tests/test_adapter_wzdx.py touched.
