@jakemas Thanks for pushing on this. Can you add a short description of the approach to the PR and also adjust the documentation? What is the (statement of) the main theorem? I don't see it on first look through the proof files.

Marking as Draft until ready. Please also review and adjust as per your judgement the AI generated top-level documentation in the proof script.

Thank you for taking a look! Ok I've updated the README, and reformatted the statement of the main SUBROUTINE_SAFE theorem so that it's more readable and consistant with others. e.g.:

let MLDSA_REJ_UNIFORM_ETA2_SUBROUTINE_SAFE = time prove
 (`?f_events:int64->int64->int64->int64->num->int64->int64->
             (bool list)->(uarch_event)list.

      8 <= val buflen /\
      LENGTH inlist = val buflen /\
      ALL (nonoverlapping (word_sub stackpointer (word 576),576))
          [(word pc,LENGTH mldsa_rej_uniform_eta2_mc);
           (buf,val buflen); (table,4096)] /\
      ALL (nonoverlapping (res,1024))
          [(word pc,LENGTH mldsa_rej_uniform_eta2_mc);
           (word_sub stackpointer (word 576),576)]

@jakemas Great! I think there's more documentation to update, though, can you check the toplevel docs as well please?

@jakemas Can you also check the other docs?

@hanno-becker yes I did. I don’t see any more that specifically mention this gap. Are you aware of any?

hanno-becker · 2026-08-20T18:57:31Z

I think SOUNDNESS.md needs updating.

hanno-becker · 2026-08-20T18:58:04Z

The spec looks great, it's exactly what I had in mind.
