What is wrong with this data

AG6 is missing hours, and a few of the markets that traded.

• It holds 136 of the 333 hours in its span. 2026-08-01T13 to 2026-08-15T09, 41% hour density. The 197 hours it does not hold are absent outright. The hours it does hold are as full as their neighbours. hour census over the served AG6 objects, 2026-08-31
• Traded coverage is nearly whole. Ratio 0.9977 across the six AG6 hours picked in advance for the audit, 47 traded markets missed in total. On the hour read in depth, four markets traded with no book, with fill counts of 171, 5, 4 and 2, and no phantom fills at all. the audit's check against on-chain fills, 2026-08-31
• Its market universe is broader than pmxt/v2's. On the seven hours they share, AG6 lacks 0.55% of the markets v2 holds, and v2 lacks 3.09% of the markets AG6 holds. the audit's comparison of the market sets on the seven shared hours, 2026-08-31
• On the hours they share, AG6 is more complete than pmxt/v2 on the markets that traded. Both corpora measured against the same set of on-chain fills across all seven shared hours: AG6 0.9972, pmxt/v2 0.9896. The split behind that: markets present in v2 and absent from AG6 are 47 traded and 4,298 untraded; markets present in AG6 and absent from v2 are 246 traded and 24,688 untraded. So most of what AG6 lacks never traded, and only 47 markets that did trade in those seven hours are in v2 and absent from AG6. That is a different count from the 47 traded markets missed in the six drawn hours above, though the two happen to match. No phantom fills appear in any of the seven hours. That is expected: phantom fills ended on 2026-06-19 and these hours are all in August. It is a consistency check passing, not evidence that the column is never true. on-chain fills for the 7 shared hours, joined to both corpora, 2026-08-31

Measured against the chain

Every figure here is measured against on-chain fills for the same hour, by a program that reads the chain and never reads this archive. Six hours were drawn, and which six was written down before anything was measured. Six hours is a floor, not a sample large enough to describe a corpus, so nothing here is a population rate.

Our own capture scored 1.0000 on the same check. This corpus is at 0.9977. Both round to 100%. In whole markets, 47 of the 20,601 that traded have no book here. See all four side by side.

Markets held, against markets traded

A corpus holds books for many markets that nobody traded in a given hour. Those books are what let you ask about a quiet market, not only a busy one. This counts both sides for each drawn hour.

Median 38.8 markets held for every one that traded, across 6 drawn hours spanning 33.5x to 43.2x.

Our own capture holds about 52 books for every market that traded; this one holds about 39, roughly 1.3 times fewer. What it holds can still be trusted: this is a statement about how much of the market it watched, not about whether what it recorded is right. See all four side by side.

Breadth is not completeness. This number says nothing about whether the markets that did trade have books; the coverage ratio above measures that. The two are computed from different counts and rank the four corpora in the same order.
