First official-state-DOT-API pattern landing. Two adapters in one PR:
- itd_511 (event-class): polls Events (60s) + Advisories (300s) from
https://511.idaho.gov/api/v2/get/{event,alerts}. Decodes EncodedPolyline
to LineString via the polyline lib (bookend LineString or Point fallback);
ITD Severity string mapped None->1 / Minor->2 / Major->3 with
IsFullClosure=true forcing 3 regardless; RecurrenceSchedules /
Restrictions / DetourPolyline pass through unmodified. Advisories ship
as structural pass-through under data.advisory since the upstream
/alerts endpoint currently returns []; per-record try/except keeps a
surprise shape from sinking the cycle when ITD posts its first one.
- itd_511_cameras (telemetry-class): polls Cameras (600s). One event per
camera per UTC day; image URL passes straight through to <img src>.
Region uniform US-ID with data.source_jurisdiction preserving the raw
upstream Source field for the ~1.2% cross-DOT border-region mirrors
(UDOT / ODOT / WYDOT / WSDOT / NDot / MTD / DriveBC / Lemhi County).
Subject convention (v0.9.20 forward): central.traffic.<event_type>.us.id
and central.traffic_cameras.us.id.<camera_id>. Castle Rock state_511_atis
keeps its bare-state subject; consumers stay on central.traffic.>
wildcards during the A/B comparison window.
Retry predicate tightened from the Castle Rock / TomTom precedent: 5xx +
connection / timeout retry; 4xx other than 429 skip-with-warn (don't
burn quota on permanent errors); 429 honors Retry-After once then
retries. API key (alias 'idaho_511') travels in the ?key= query string,
so every error log path runs through self._redact() to scrub the URL.
Both adapters ship disabled; operator enables via GUI after registering
the API key with 'python -m set_api_key idaho_511'. Reuses existing
CENTRAL_TRAFFIC and CENTRAL_TRAFFIC_CAMERAS streams -- no archive
restart needed.
Scope-cap exception: this PR is ~1.5k lines vs. the standard 500-line
cap, authorized as a one-time exception for the first
official-state-DOT-API pattern landing. Two adapters + their tests +
real-API fixtures naturally exceed the v0.9.x adapter-cap budget.
