Instead of shelling out to https://gridmap.org/locate/:callsign for callsign → lat/lon lookups, ports the resolver pipeline from gridmap-web into this project so the whole flow runs in-process. New modules: - Microwaveprop.Qrz — cache facade over the QRZ.com XML callsign API. Looks up from qrz_callsigns first, falls back to a live fetch, and upserts the result with a configurable cache_ttl_hours (default 168h / 7 days). - Microwaveprop.Qrz.Client — HTTP/XML client against https://xmldata.qrz.com/xml/current/. Holds the session key in an Agent, transparently re-logs-in on :session_expired, and parses responses via xmerl. - Microwaveprop.Qrz.Callsign — Ecto schema for the qrz_callsigns cache table, binary_id primary key per project convention. - Microwaveprop.Qrz.Record — slim struct with only the 11 fields we actually consume (identity, name, grid, address, lat/lon). The full XML payload stays in the raw :data jsonb column for anyone who wants the other ~40 QRZ fields. - Microwaveprop.Geocoder — Req-based client against the Google Maps Geocoding API. Only called as a fallback when QRZ has no explicit <lat>/<lon> for the callsign. - Microwaveprop.CallsignLocation — orchestrator. Reads the callsign_locations cache, on miss calls Qrz then either uses QRZ's coords directly or geocodes the formatted address, snaps to an 8-char Maidenhead grid via Microwaveprop.Radio.Maidenhead, and upserts the result. Microwaveprop.Radio.CallsignClient.locate/1 is rewritten to delegate to CallsignLocation.lookup/1 and shape the response back to the existing {:ok, %{callsign, gridsquare, lat, lon}} contract so the callers in PathLive and RoverLive don't change. Wiring: - priv/repo/migrations/20260413000000_create_qrz_callsigns_and_callsign_locations.exs creates qrz_callsigns and callsign_locations with unique indexes on :callsign. - Microwaveprop.Qrz.Client added to the application supervision tree so the session Agent is started. - :xmerl added to extra_applications so the release bundles it. - config/test.exs wires Req.Test plugs for Microwaveprop.Qrz.Client and Microwaveprop.Geocoder, forces cache_ttl_hours: 0 so the cache never short-circuits test-level stubs, and supplies dummy QRZ credentials. - config/runtime.exs pulls QRZ_USERNAME / QRZ_PASSWORD / QRZ_AGENT and GOOGLE_API_KEY from the environment so prod and dev can configure both upstream keys out of band. Tests (ported verbatim from gridmap-web): - test/microwaveprop/qrz/callsign_test.exs — schema/changeset - test/microwaveprop/qrz_test.exs — cache hit, cache miss, TTL behavior, upsert on stale, error passthrough, case-insensitive input - test/microwaveprop/geocoder_test.exs — success, zero results, request denied, transport error - test/microwaveprop/callsign_location_test.exs — end-to-end flow including the QRZ-lat/lon shortcut and the missing-address error path All 1294 tests still pass. Credo strict clean.
