APPLIED

status detail

Applied 3 November 2026, in answer to an external audit. Reversible: the mapping is recorded and the old identifiers are kept.

rule

Eight sources that shared an identifier with another source were renumbered, with the shared identifier kept as an alias, and one double registration was marked. Tested first: no count, rating, Outlook, independence determination or provenance computation reads the source identifier. The effect was limited to evidence attribution on four retrieval records.

scope

Source registry identifiers.
