Revision and schema helpers preserve the distinction between a scientific revision and endpoint health.

Important limitations

• humidity: Choose maximum or minimum relative humidity explicitly.
• precipitation: Recent gridMET assets can be provisional and later replaced.
• radiation: Surface downward shortwave radiation, not net radiation.
• temperature: No native daily mean temperature variable; choose maximum or minimum.
• vpd: PRISM VPD is not registered until its daily NcSS path is validated.
• wind: Represents gridMET 10 m wind velocity, not gust speed.
