RMP.5:5.3 - A directive date and an earlier practice

A historical claim says that a practice first began after Directive-D and was caused by it. Inspected authenticated records establish the directive’s date, but an earlier workshop series is inaccessible. The current answer establishes the inspected chronology and retains the unresolved earlier-practice possibility. The catalogue’s description is not an examination of the missing records, and the gap is not evidence that the practice was absent.

An authenticated earlier ledger later becomes available and records the practice before the directive. It defeats the chronology in which the practice first began after issuance. It does not, by itself, establish what caused the earlier practice or exclude an effect of the directive on later adoption. The revised answer keeps those different claims separate.
