How to read this page
Evidence is kept at record level
A source clause can contain several separately mapped Section 20 items and an explicit alert reference. One item may be read by an SRV, another updated by a different service, and another have only an Alert or local-HAN path. Accordingly, the clause summary does not collapse those distinctions into a single covered or uncovered result.
