Pulls verified RF hops from aprs.me's 24h packet retention, computes factor vectors at each hop's midpoint via the existing Recalibrator, and runs gradient descent against random-baseline negatives. Dry-run: prints proposed weights but does NOT mutate band_config.ex. Refuses to fit on <50 positive or negative samples.

Smoke test for the APRS-144 calibration mix task. The task is mostly

orchestration: Aprs query + PathParser + Recalibrator. Each piece has

its own unit tests, so this only confirms the wiring holds together
|

and that the empty-corpus path exits via the "refusing to fit" branch
|

rather than crashing.
