Coinbase returned 289 rows because the end-boundary bucket was included; after filtering starts to [2026-09-20T23:00:00Z, 2026-09-21T23:00:00Z), there were 288 unique, consecutive 300-second buckets from 2026-09-20T23:00:00Z through 2026-09-21T22:55:00Z, with no gaps. Exact-decimal interval low=80837.42 at 2026-09-21T01:55:00Z and high=87397.00 at 2026-09-21T20:25:00Z. A retained bucket at 2026-09-21T09:35:00Z had low=84661.51 and high=85257.00, so 84661.51 <= 85000.00 <= 85257.00 and the boolean is true.
