Evidence & Method

A finding should show its basis.

BlueLedger's method asks three questions: what should we expect from the sourced baseline, what do the available records show, and what still needs an explanation?

Expected. Detected. Gap.

Expected: establish the baseline. Identify the source, instrument, relationship and effective date. A baseline is a reference for comparison, not a guarantee that one source answers every question.

Detected: inspect the observation. Record what was observed, where it came from and when it was captured. A source's statement and its underlying accuracy are not the same thing.

Gap: explain the comparison. Describe the difference, its possible explanations and the evidence needed to resolve it. Where the information is insufficient or not comparable, say so.

A review has more than one useful outcome.

Aligned - the comparable records agree within the stated scope.

Explained difference - the difference has a supported explanation.

Unresolved discrepancy - the records differ and the explanation remains open.

Insufficient coverage - available information is not enough to assess the question.

Not comparable - the records describe different instruments, periods or relationships.

A simple example.

Illustrative example. Not an actual issuer finding.

Expected

A sample issuer record shows a name change effective on 1 June.

Detected

A sample venue record captured on 8 June still displays the earlier name, but does not state its effective date.

Gap

The displayed names differ. This mismatch does not establish an unauthorized listing or misconduct. A dated venue history may explain whether the record reflects an earlier period or needs correction.

Review status: Unresolved discrepancy

What would help: the venue record's effective date and the documented relationship between both records and the same instrument.

Dates and source relationships matter.

A record's effective date, publication date and the date you observed it can differ. Two agreeing records may also rely on the same upstream source. More records do not automatically mean independent corroboration.

What “evidence-grade” means in our product direction.

It means designing for inspectable sources, clear chronology, documented comparisons, visible limitations and a review history. Each release must show which controls are implemented. The term does not certify legal admissibility or guarantee a regulatory outcome.

Keep observation and interpretation separate.

An observation describes the available record. An inference offers an interpretation. An unresolved issue remains open. AI-generated explanations must not turn uncertainty into certainty or substitute for professional judgment.
