taste
Domain-first store/port design for any codebase: product-shaped APIs, swappable backends, schema at boundaries, one vocabulary catalog (derive don’t re-author), no infrastructure names on the domain surface. Use when adding or refactoring persistence, cache, policy resolve, registries, or anything that might leak Redis/SQL/HTTP/SDK names into shared contracts. Taste: one fact one place, HOF as shared ritual not twin wrappers, call-site clarity, dumb engines, challenge early / cut ruthlessly, DX (cascading IntelliSense) as correctness, policy resolve → push-down query plan (not load-all-then-filter), no hardcodes when dims/rows already name the filter.
