Use the decision guides
Learn the shared shape behind Cogitave's database-selection, infrastructure-selection, and model-selection guides - a default, a decision tree, and an ADR-gated deviation rule - and walk a real workload to a justified, recorded choice.

By the end of this module, you'll be able to:
- Explain the three-layer guidance model from ADR-0021 - selection, radar, domain - and where the decision guides sit in it.
- State the shared shape every decision guide follows: a default, a walkable decision tree, and a deviation rule gated on a measured need and an ADR.
- Walk the database-selection and infrastructure-selection decision trees for a real workload to the guide's prescribed answer.
- Explain the model-selection guide's "most capable first, optimize down with evidence" posture and when escalating or descending a tier needs an eval or an ADR.
- Recognize when a choice is the ratified default and needs nothing recorded, versus when it is a deviation that must cite a measured ceiling in an ADR.
