- * Keyless Loader-path smoke for the Code Mode overlay: boot the REAL
- * example through the `@deepseek-ai/dsh-stdio-agent` bin against
- * `code-mode.cordis.yml` (the cordis Loader, `unwrapExports`, the include
- * patches over ./cordis.yml, the worker-thread code runtime, and the
- * registry in `mode: code`), then close stdin with no prompt and assert
- * the Code Mode banner + a clean exit.
- *
- * No prompt is ever sent, so the model is NEVER called and no `run_code`
- * turn happens — a dummy key lets `llm-deepseek`'s key-PRESENT check boot
- * the tree. This is the export-shape guard (postmortem 0001) for the Code
- * Mode composition; the with-key proof lives in `code-mode.e2e.ts`.
+ * Keyless Loader-path smoke for the Code Mode overlay: boot the real include
+ * tree through stdio-agent and `code-mode.cordis.yml`, then close stdin without
