      # Before lint: the type-aware ESLint config resolves vendor packages via
      # their built declarations (tsconfig.typecheck.json -> vendor/*/lib),

      # see unresolved types and erupt with no-unsafe-* errors.

      # Doc-sync gates (RFC 006). doc-typecheck compiles the fenced ts blocks in
      # the docs and resolves vendor packages via their built declarations, which
      # the typecheck step above emits — so it runs after typecheck. The event
      # taxonomy check only reads source. Same `doc-sync` script the pre-push
      # hook runs (ADR 0007: one source of truth).
