Fahali's product is checkable claims. A wrong public number costs more than every honest number earns. So when we get something wrong, the fix is dated, disclosed, and linked — and the evidence itself is never silently edited.
Claims in public copy — marketing pages, articles, methodology text, metadata — are corrected the same way they were published: in place, but never silently. Every material correction carries its date and a note in the method & record changelog.
Measurements are never "corrected" into better numbers. When a measurement was wrong, the correction is the admission, the cause, and the fix — the recorded outcome stays what it was. The record's job is to be true to what happened, not to look good.
The signal-to-outcome ledger — millions of rows, each registered with its claim and horizon before the outcome existed — is never deleted, re-scored, or re-labeled to improve the record.
Judgment bugs found after the fact are handled by deterministic replay where possible, or voided to unresolved where not — both disclosed, never silent. Rows before 2026-07-02 12:00 UTC carried fabricated direction labels and win-only scoring; they are permanently excluded and never re-judged, because a claim that was never made cannot be recovered.
If you find a wrong number, a broken link, or a claim that does not match the record, tell us. Email [email protected] with the subject line "Correction" and include the URL and what you found.
We treat reports as a gift. A reader who checks us is the whole point of building a checkable product. Corrections raised by readers are recorded the same way as our own.
