  "source": "You now know that Cogitave answers \"which database, which infrastructure,\nwhich model\" the same way every time: a stated default, a real decision tree,\nand a deviation rule gated on a measured need and an ADR - never per-team\ntaste, and never guessed from memory.\n\nIn this module, you:\n\n- Learned the **three-layer guidance model** from ADR-0021: selection guides\n  say *which* family for *which* workload, the technology radar says *what*\n  is adopted, and the domain standards say *how* to build with the choice.\n- Learned the **shared shape** every decision guide follows - a default, a\n  walkable decision tree, a machine-readable matrix an agent can query, and a\n  deviation rule that requires a measured ceiling recorded in an ADR (or, for\n  model selection, an eval).\n- Walked the database selection tree to Cogitave Core's query layer for a\n  full-text search need, the infrastructure selection tree to a container on\n  managed Kubernetes for a long-running service, and the model selection\n  posture to the most capable tier for a new, correctness-critical task.\n- Learned that landing on the default needs **nothing recorded**; only leaving\n  it does, and you now know exactly what that record must state.\n\nThat completes the four modules of the \"Patterns and golden paths\" path:\nreuse-first engineering, navigating the patterns catalog, inheriting the\nproject baseline, and now using the decision guides to make a justified\ntechnology choice.\n\n## Next steps\n\n- @cogitave.learn.paths.patterns-golden-paths - return to the path to claim\n  your trophy.\n- **ADR-0021** is the full decision that governs all three guides, worth a\n  re-read.\n- The **model selection** standard, in the estate's standards repository, has\n  the cost levers and the eval-gated routing rule; revisit it before your\n  next production model choice.\n",
