Adds Roads511Adapter.to_event(), wiring the state 511 road-events adapter
into the notification EventBus following the Phase 2.7 traffic pattern.
to_event() design:
- Category: fixed "road_closure".
- Severity: passed through unchanged from the adapter's existing
_parse_event logic (priority on closure, else routine).
- Summary enriched with closure status, roadway, and description.
- group_key: the stored event_id (already the stable "511_{id}" key), so
re-polls of the same incident coalesce.
- inhibit_keys: a single key equal to group_key. Severity tiering is
delegated to the pipeline Inhibitor (ranks routine<priority<immediate
per shared key, suppressing lower-severity re-emissions of the same
incident within the Inhibitor TTL). No severity encoded into the key.
- Defensive: missing lat/lon or missing event_id returns None; whole body
is try/except-guarded (returns None on corruption).
Store wiring: no change. EnvironmentalStore._ingest()'s generic "else"
branch already emits any adapter exposing to_event() (live since 2.6.5).
Rule 17: to_event introduces no new tunable. (The state base_url / bbox /
api_key already exist in Roads511Config and env_feeds.yaml; secrets go in
/data/secrets/.env via ${VAR}, never git.)
Tests: tests/test_adapter_roads511.py (14 tests) mirrors
test_adapter_traffic.py -- category, severity pass-through,
group_key/inhibit_keys, field population, defensive cases. Full suite:
161 passed.
live smoke test SKIPPED: Idaho 511 v2 (511.idaho.gov/api/v2) requires an
API key ("Invalid Key" response) and none is available in .ref/credentials
(cannot self-register). Per the standing key-less-adapter policy, the code
+ unit tests are committed and Gate D is skipped; roads511 is left disabled
in prod (enabling it keyless would only emit HTTP 400 errors). The
to_event() path is fully unit-validated and structurally identical to the
live traffic/FIRMS wiring (same EnvironmentalStore->EventBus path); live
validation will run if/when an Idaho 511 key is provided.
