Annex A, Notes on terms and concepts
Annex A has 5 sections in the published contents of ISO/IEC/IEEE DIS 42024. The public preview gives the titles but not the body text, so each page states what the section covers, the definitions it builds on, the evidence to keep and the gaps it exposes, and says plainly where the text is not public.
An annex is read after the clauses, and these two are notes and guidance rather than a clause requirement. The pages here label the status as not stated in the public preview, because the preview does not state it.

How to use the annexes
Annex A connects the terms; Annex B applies the judgement of architectural significance. Use Annex A when the practice argues about what a word means, and Annex B when it argues about whether a decision belongs at architecture level. Both are better read with the clause 3 definitions open.
