USD-M metrics: two checksum mismatches and reproducible blank/timestamp defects
Observations: 2026-09-10 UTC.
Please investigate and publish corrected archives/checksums, and clarify the timestamp convention and blank-value semantics. Originals and HTTP receipts are preserved.
Across our frozen 190,399-key listing: 48,221 numeric/period-defective targets, 395 structurally defective targets, and two checksum inconsistencies remained after exact-source refresh. This is an observed collection scope, not a claim about all Binance datasets.

Reproduction: download each URL and its .CHECKSUM sibling, then run shasum -a 256 -c filename.zip.CHECKSUM in the download directory. Three observations including the initial recovery spanned at least one hour; both pairs remained inconsistent.

A local comparison of all 395 timestamp-defective archives with adjacent-day archives found zero exact same-timestamp duplicates, 14 conflicting comparisons, 789 same-timestamp absences and five unavailable/unverified neighboring comparisons. No timestamps were shifted and no blanks were imputed. Reordering is not a repair of absent values.
Please confirm whether blanks mean unavailable observations or a defined zero-denominator condition, and provide historical corrections where possible.
