Context packet
Current/recent weather, rainfall/humidity, temperature/wind, soil properties, elevation/slope/drainage proxies, irrigation zone, crop calendar, previous field cases/treatments, regional signals and approved satellite indicators.
Priority
Use departmental and Pakistan Meteorological Department data where accessible. NASA POWER, SoilGrids and Copernicus DEM are candidate gap-fill/baseline sources and must be validated locally.

Limitations
Global gridded data may be too coarse for a field. Record spatial resolution, observation time and uncertainty. Verified farmer/field observations can supersede coarse estimates.
Cache/failure
Cache terrain/soil by dataset version/grid; expire weather by update frequency. If unavailable, mark it unavailable—never infer current conditions from generic knowledge.
