Use when adding or migrating a data Source into the v2 Effect-native slice (src/sources/<x>/ or src/kernel/**). The end-to-end gold-standard recipe — Schema.TaggedErrorClass taxonomy, Context.Service + Layer.effect, kernel http, bounded fan-out, classified retry, Match over switch — so the new slice passes the v2-strict static checks on the first try.

Use when adding or changing a rule in tooling/static-checks/check-declarative-errors.ts (the lint:errors gate). Covers the AST-walk model, the two-tier strictPrefixes contract, the shared helpers, and the iron rule that every new rule must be proven false-positive-clean against the six gold files before it lands.
