Separate market and store history
Without store, the response describes aggregate price intelligence. Add store when you need one seller’s observed history and keep that narrower context visible in charts and reports.
Do not invent values for missing observations
A gap means no usable observation was available for that point. Keep gaps visible or explain interpolation explicitly instead of implying uninterrupted source coverage.
