/** Slice 0.9 — TypeScript-backed closure-classifier adapter (Node/codegen side).
 *
 *  This module is the ONLY place where the browser-safe closure-classifier seam
 *  is wired to the TypeScript-AST gate in `closure-eligibility.ts`. Because it
 *  statically imports `closure-eligibility.ts` (which imports `typescript`), it
 *  is reachable ONLY by direct module/subpath import — it is intentionally NOT
 *  re-exported from the `@kernlang/core` barrel, so importing the barrel or the
 *  parser never drags in `typescript` (R1 barrel-isolation).
 *
 *  Codegen and any caller that needs to parse block-bodied arrows imports
 *  `typescriptClosureClassifier` from here and injects it via
 *  `parseExpression(input, { closureClassifier: typescriptClosureClassifier })`. */

/** The full-fidelity closure classifier: the TypeScript-AST gate that has

 *  accept/reject behavior (`closure-this`, `closure-nested-function`, …). */
