OptionalfromInterval token, e.g. "1m", "5m", "1h", "D".
OptionalnoSkip the cached entry, fetch, and replace it with the fresh result.
OptionalsignalCancel this consumer's request. Existing feeds may ignore cancellation.

unit. Absent is the provider's default. A feed serves only what it
declares through dataVariants, and never derives one series from another.
