/// store call (and pushed callers onto an OOM-prone CLI fallback). The
/// alias must route to the same handler as `/drawers`.
/// What: Creates a real palace via the registry, then GETs the `/memories`
/// alias and asserts a 200 with a JSON array body (the list-drawers shape).
/// Uses GET, not POST, so the test stays embedder-free (no ONNX load).
