A domain level alone is not evidence that each criterion holds. This is a rubric-based discussion checklist, not a verified gap analysis or a customer implementation roadmap. Lower-level criteria must continue to hold. D L1 means Data at Level 1; criterion D1 means “Ownership and contract”.

Bring evidence, not just a higher number.
For this landmark: Meaning tests, entity matches, permission-aware retrieval and index freshness.
Identify an owner for each capability; compare present practice to the criteria; record unknowns; implement and test missing controls; then reassess using the full questionnaire. These are general discovery steps, not a claim that purchasing a specific tool achieves a level.
All criteria shown for each dependency domain matter; this landmark is a way into the framework, not a shortcut around the rest of the assessment. Level 4 still requires ongoing review and evidence.
