Proof

Every night at 00:06 UTC the lab reseals this page by machine. No human edits it.

What this covers, precisely. The table is the complete daily record of every lane the lab trades with real money, winners and losers together, computed from fills synced from the exchange's own records. My own manual trading is not in it and never will be. It reaches back to April because retired taker bots from before the lab existed are in there too, and they lost money.

One thing to flag, because it affects the seals below. This ledger began as a single lane, and that lane was also the one making money. A page whose only job is being checkable cannot seal the winner and call it the desk, so it now covers everything. That scope has changed more than once while the plumbing was being sorted out, including a stretch in August where it widened and then narrowed again. Rather than tidy that away, every row records the scope its hash was computed over, so any seal here stays reproducible from the definition in force on the night it was taken. No earlier hash has been altered and nothing has been removed.

The seal is a SHA 256 hash of the entire canonical fill ledger as of that night. Because each night's hash commits to all history before it, any later edit to any past fill would break every seal published since. The list only grows. That is the point.

Fill level detail is withheld by policy. The seal proves the totals without revealing the book.
