As discussed in Hagenberg, there is interest in having a UB/IFNDR Annex
as a first step towards issuing recommendations on how to mitigate
those.

We take Shafik's P3075 and his work on a LaTeX patch as a basis for that.
His work (plus fixes) has been migrated to the main github repository for the
Working Draft, represented in this pull request:

https://github.com/cplusplus/draft/pull/7826

A PDF rendering of the current state is available here:
https://github.com/cplusplus/draft/actions/runs/14405692379/artifacts/2928265136
but that link will become stale as updates are merged.
For those who can't access github, I've uploaded a PDF snapshot here:
https://wiki.edg.com/pub/Wg21telecons2025/SG12/std-ub-ifndr.pdf

An initial collection of editing instructions is here:
https://github.com/cplusplus/draft/wiki/UB-and-IFNDR-Annex

A sample pull request against the "working branch" is here:
https://github.com/cplusplus/draft/pull/7828

Going forward, all discussion should happen on the "sg12" reflector
(as agreed by Herb and JF).

Thanks,
Jens
