+  - **pi — DONE.** Enabled the existing real `createSession('pi')` headless
+    suite in default core Vitest coverage and unskipped the upstream Pi SDK bash
+    tool path. The suite proves initialization over the native sidecar
+    transport plus real ACP write-tool and bash-tool flows inside the VM. Proof:
