Pin the exposure
Click any point on the map. The pending marker captures lat/lon to four decimals — good to ~11 m at Korean latitudes.
Ingest the signal
One action call fetches five years of daily precipitation, max temp, and min temp from Open-Meteo's ERA5 archive and writes it to Convex.
Design the trigger
Jump to the Trigger Designer and point its inputs at the new dataset. The DSL is the same serialized object the backtest worker consumes.
