+ * Source-path Loader smoke through the package's own bin, covering initialize, session/new, and
+ * session/load across the `unwrapExports` path implicated by postmortem 0001. Session creation and
+ * unknown-id loading reach factories but not the model, so a dummy key is sufficient. The temp cwd
+ * is also the session workspace, and an explicit root tsconfig keeps unbuilt path aliases resolvable
+ * when the child starts outside the repository.
