Hour audit: 2026-10-05T14

back to the files for this hour · how the archive is audited

Every number on this page is a stored measurement read from this hour's own records: its manifest.json, its witness statistics sidecar, and the corpus attestation. Nothing here is computed from the served bytes at the time you load the page, so no line below claims the bytes are correct. The digest and the one command that checks them are printed instead.

No findings

Every check that could be evaluated for this hour passed. That is not the same as the hour being perfect: it means the records this archive keeps about it agree with each other and with the corpus ledger.

UPSTREAM    status feed unobserved for this hour. Our incident register was last checked against the venue's feed at 2026-09-23T20:35Z, before this hour ended, so nothing has looked yet. This is a could-not-look and never an all-clear.

The words in this report

Each line in the CHECKS block states what was found, not what was hoped for: a check that passes is named for the thing that is true, and a check that does not is renamed to the thing that is wrong. So FINDING never sits beside a sentence asserting the opposite of the one below it.

The report above is fixed-width text, so nothing in it can be clicked. The same terms are linked here instead. Its verdict is a statement about minutes and nothing else. The row it reports comes from this hour's own manifest and its witness-statistics sidecar, and the completeness line comes from the corpus attestation. The gap between the joined and merged counts is deduplication, not loss, and the boundary drops are the duplicates discarded at the seam with the hour before. Where the history line names a supersession, this hour was rebuilt to a better state after it was first published. The precision is the timestamp resolution these files carry.

Detail

The same records, per product. A product holding no rows renders its zero rather than being dropped: dropped and empty are indistinguishable to a reader, and only one of them is a defect. A cell reading not meas. is one nothing published, which is a third thing again and never a zero.

The class column is the merger's own verdict for that product, and it is keyed to CONTRIBUTION rather than presence. FULL means every machine expected to be capturing this hour delivered rows for that product; PARTIAL means some did and some did not; SINGLE-BY-DESIGN means only one machine was ever expected, and SINGLE-BY-DEFECT means several were and one delivered. So PARTIAL here is a statement about the fleet, not about the product being damaged or truncated: the rows that are present are whole.

Captured and supplied are different numbers

Captured is how many rows each machine's own feed carried. Redundant capture means these OVERLAP, heavily and on purpose, so they do not partition the file and their sum is larger than it. Two machines each capturing nearly every event is the archive working, not double counting.

Supplied is how many rows of the merged file actually came from that machine. This one does partition: it sums to the file's row count exactly. But it is decided by the merge's tie-break, so a machine can capture almost everything and supply almost nothing. Read alone, either number tells a false story about the fleet, which is why both are printed and neither is called "the witness share".

What the skew columns mean

Arrival skew is the receipt timestamp minus the venue timestamp, in milliseconds. For six of the seven products the sidecar interprets it as transport latency, and marks that interpretation assumed: it rests on the venue timestamp being emit time, which we cannot verify from outside.

book is not latency and must not be read as latency. Its venue timestamp is the last time the book changed, so the sidecar interprets it as book staleness and warns in its own note that large values mean a quiet book rather than slow transport. Its maximum runs to weeks for that reason. This is why the table above gives a row per product per machine and never one figure for the hour: percentiles do not average, and these seven do not measure the same quantity.

Check it yourself

The digest above is a claim. This is how you refuse to take our word for it:

curl -O https://archive.pendulumflow.com/v3/2026-10-05/14/2026-10-05T14.parquet

# compare with the sha256 line in the report above

A range digest certifies bytes. That those bytes are the product the manifest names comes from the manifest, which is why both are published and both are checkable.
