Public impact record / measured conservatively
Reach is visible.
Impact must be earned.
EPSILON separates anonymous browser signals from server-verified research use and independently reviewable contribution. A page view is unverified reach. A historical evidence run is counted only after the server completes it. A substantive external challenge becomes impact only when it remains publicly inspectable.
Unique real-data evidence configurations completed and recorded by the server.

Evidence hierarchy
Not every number means the same thing.
- 01 / Reach
Someone encountered the work.
Visits, impressions, and video views are useful distribution diagnostics. They are not counted as adoption or educational impact.
- 02 / Use
The server completed a research action.
Only completed historical-data evidence runs are shown as verified product use. Browser openings and link clicks remain explicitly unverified signals.
- 03 / External challenge
Someone tested the method itself.
A review counts only when a real person identifies a specific assumption, evidence gap, interpretation risk, or product weakness in a publicly linkable record.
- 04 / Change
The criticism altered the work.
Accepted challenges link to the resulting experiment, issue, correction, or product change. Unfavorable findings remain visible.
Falsification challenge / open
Find the assumption
we failed to expose.
Start with a question about a backtest conclusion. Describe the claim, the assumption you distrust, and an optional public example. A code contribution is not required. Completed experiments and feedback-led changes need their own records.
Participation requires no stars or endorsements. No investment claims. No account identifiers in the measurement ledger; coarse source categories only; rolling 90-day measurement window. Unavailable measurements display a dash, not zero.
