+// check-doc-authoring.mjs — guard the docs/skills corpus against the bare
+// metadata-literal anti-pattern (#2035 / ADR-0059).
+//
+// The example apps are kept on the `defineX` factories by an ESLint rule, but
+// TypeScript code blocks inside Markdown/MDX are not type-checked or linted by
+// anything — which is exactly how skills/ and content/docs/ drifted back to
+// teaching `: Page = {}` while the examples stayed clean. Skills are the corpus
+// AI authors from, so a bad sample there is worse than one in app code.
+//
+// This scans ```ts|typescript|tsx fenced blocks for an exported metadata literal
+// annotated with one of the 16 factory domains (or its `Input` alias) instead of
+// being wrapped in the `defineX(...)` factory, and fails if it finds one.
+//
