Adds TomTomTrafficAdapter.to_event(), wiring the traffic adapter into
the notification EventBus following the FIRMS pattern (Phase 2.6).
to_event() design:
- Category: fixed "traffic_congestion" (a road closure raises severity,
not category).
- Severity: passed through unchanged from the adapter's existing
_fetch_point logic (priority on closure / heavy congestion, else
routine). No threshold is re-derived or introduced in to_event.
- Summary enriched with current/free-flow speed, % free flow, closure,
and confidence.
- Defensive: missing lat/lon or missing corridor identity returns None;
the whole body is try/except-guarded (returns None on corruption).
Inhibit-key composition:
- A single stable per-corridor key, "traffic_{corridor}" (lowercased,
spaces->_), is used as BOTH group_key and the sole inhibit_key. This
matches the adapter's own event_id, so re-polls of a corridor coalesce.
- Severity tiering is delegated to the pipeline Inhibitor, which ranks
routine<priority<immediate per shared inhibit_key: a higher-severity
emission for a corridor suppresses lower-severity re-emissions of the
same corridor within the Inhibitor TTL window. No severity is encoded
into the key (mirrors FIRMS's spatial-key approach).
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 api_key is injected via
the secrets channel ($TOMTOM_API_KEY in /data/secrets/.env, referenced
as ${TOMTOM_API_KEY} in env_feeds.yaml) -- the GUI-editable reference
stays in config while the secret never enters git. The only other knob
in play is the pipeline-level Inhibitor TTL (1800s, set in
build_pipeline), which is pipeline infrastructure, not traffic-owned;
left out of scope.
Tests: tests/test_adapter_traffic.py (15 tests) mirrors
test_adapter_firms.py -- category, severity pass-through,
group_key/inhibit_keys, field population, defensive cases. Full suite:
147 passed.
Smoke test (prod, Magic Valley corridors I-84 @ Jerome, US-93 Perrine
Bridge, US-30 Twin Falls): clean startup, 6 env adapters loaded, no
traceback. "TomTom traffic updated: 3 corridors" (no auth/DNS error),
then 3 Events emitted to the pipeline bus with traffic_congestion
category -- the full store->bus->pipeline path observed live. Emission
count stable at 3 (one per corridor, is_new-gated).
