From the source SKILL.md

Classification decides everything, and it decides it in an order most teams get backwards. The sequence is: prohibited first, then role, then risk tier, then duties. A team that starts at "what documentation do we need for a high-risk system" has skipped the two questions that could have ended the project or moved the entire obligation set onto someone else.

1. Art. 5   prohibited practice?  ──yes──► BLOCKER. No compliant version exists.
        │ no
  2. role     provider · deployer · importer · distributor
        │            (Art. 25 can turn a deployer into a provider)
  3. tier     Annex I / Annex III high-risk?  ──► Art. 6(3) derogation available?
        │                                          (not if it profiles people)
