Results

Costs: 10 basis points for buying and selling (0.10%), taken off every result. The benchmark is S&P 500 (SPY), measured from the same entry close to the same later closes. Bad calls stay in the record like every other, and a result that can't be measured counts against the Truth Scores as a miss.

What this proves

That each entry matches its hash and follows the entry logged right before it, and, once its day is over, that it's part of that day's checkpoint, whose digest fixes everything logged up to then. It doesn't prove on its own that the whole log was never rewritten: only a copy of a checkpoint kept outside this site can. No copy is kept outside this site yet, so these checks show the log is consistent, not that it was never rewritten.
