 ## ✨ Features
 
-  * **No deep learning dependencies**: The policy stays on the server. This side needs only `gymnasium`, `websockets` and `msgpack`, so environments pinned to old `mujoco-py` or `cython<3` can be used with a modern training stack.
+  * **No deep learning dependencies**: The policy stays on the server. The base
+    install declares nine runtime dependencies - `gymnasium`, `websockets` and
+    `msgpack` do the environment and wire work, next to `loguru`, `dm-tree`,
+    `tyro`, `plugrl-protocol`, `pandas` and `imageio[ffmpeg]` - and none of them
+    is a deep learning framework, so environments pinned to old `mujoco-py` or
+    `cython<3` can be used with a modern training stack. E1 measures that bare
+    install at 30 packages and 224M on Linux with no CUDA wheels
+    (`plugrl-server/experiments/e1-dependency-conflict/`, round 4). Correction:
+    this line previously said the client needs "only `gymnasium`, `websockets`
+    and `msgpack`", which named three of the nine declared dependencies.
+    `pandas` is declared but is not imported anywhere in `src/` today - it is
+    weight in the install, not a requirement of the runtime.
   * **Distributed communication**: `websockets` plus `msgpack` for asynchronous transfer between the server and any number of env clients, across machines.
   * **Modular design**: Separates the environment-side runtime (`plugrl-env-client`) from the shared protocol layer (`plugrl-protocol`).
   * **Command-line interface**: A `tyro`-powered CLI for starting and managing env clients.

-    Everything, with `uv`:
+    All six extras, with `uv`:
 
     ```bash
-    uv sync --extra mujoco --extra robomimic --extra atari --extra classic --extra libero
+    uv sync --extra mujoco --extra robomimic --extra atari --extra classic --extra libero --extra d4rl

+    pip install -e ".[mujoco, robomimic, atari, classic, libero, d4rl]"
     ```
 
+    Correction: these two lines were labelled "Everything" but listed only five
+    of the six extras `pyproject.toml` declares - `d4rl` was missing, while the
+    environment table below names it as the extra for `d4rl-v1`. Against the
+    committed `uv.lock`, all six resolve to 100 packages and the old five to 97
+    (`uv sync --frozen --dry-run`, uv 0.9.8): `robomimic` already carries `d4rl`
+    and `mujoco-py`, so the `d4rl` extra itself adds `gymnasium-robotics`,
+    `mujoco-py-cython3` and `pettingzoo`. Note that "all six" is not a light
+    install - E1 measures the env client with the `robomimic` extra at 7.2G with
+    16 CUDA wheels, because robomimic ships its own policy learning code.

     Note: `robomimic` and `libero` pull in `egl-probe`, whose legacy CMake build
     needs `CMAKE_POLICY_VERSION_MINIMUM=3.5` when using CMake 4+. `uv` is
     configured in this repository to apply that automatically. If you install
