First step toward physics-based HF / sporadic-E scoring. Polls GIRO's DIDBase tabular endpoint every 10 minutes for two US ionosondes (Millstone Hill MHJ45, Alpena AL945), parses the plain-text response into observation rows, and upserts into a new ionosonde_observations table keyed on (station_code, valid_time). This gets foEs (E-layer sporadic critical frequency) into the database as a direct measurement — the key input for predicting 144 MHz Es openings via ITU-R P.534-6. foF2 + MUFD are the F2-layer inputs for HF MUF predictions. Not yet wired into scoring. Boulder/Wallops/Austin/Idaho/Point Arguello are in the GIRO catalog but were silent when probed — add them back if/when they come online. Next steps: SWPC JSON (Kp, F10.7, sunspot), GOES X-ray flux, D-RAP text, and the P.534-6 Es scoring factor that uses foEs at midpoint for the 144/440 band configs.
