-Shared subprocess harness for keyless example smokes that boot the real stdio-agent bin and a real `cordis.yml` through the Cordis Loader. A test supplies absolute bin/config/tsconfig paths, optional environment overrides, and stdin lines; `runLoaderSmoke` owns the isolated cwd, DSH homes, tsx path resolution, 30-second process deadline, captured diagnostics, forced kill, EOF, and cleanup.
+Shared subprocess harness for tests that boot an app and `cordis.yml` through the Cordis Loader. `resolveExampleLaunch` selects local `src` mode (tsx and root tsconfig paths) or CI `lib` mode (plain Node and package exports) from an explicit mode or `DSH_EXAMPLE_MODE`.
 
-Successful runs return stdout and stderr only after a zero exit. Non-zero exits and deadlines reject with both captured streams. `LOADER_SMOKE_TEST_TIMEOUT_MS` leaves Vitest enough room for the process-owned diagnostic timeout to fire first.

 ## Known Limitations and Deferred Work
 
-- **Only the unbuilt tsx/Loader path is exercised** — built-bin artifacts remain the responsibility of their separate e2e smokes.
+- **Built mode requires a prior build** — the config must also resolve every named package upward through `examples/node_modules`.
 - **Captured stdout and stderr are unbounded** — a runaway child can consume memory until the deadline kills it.
 - **Timeout kills only the direct child** — a process tree spawned by a faulty fixture can outlive the smoke and needs external cleanup.
