01
Evidence and provenance
Nothing is asserted that cannot be opened and read.
Every assertion carries five things: document, location, date, custodian and hash. Opposing counsel can check it. So can the tribunal.

02
The provenance record
Five things, carried by every assertion.
The record is not a footnote. It is generated with the assertion and travels with it into the report.
03
