+# MusicMouse — repo overview
+
+Orientation doc for AI agents (or humans) working on this repo for the first time. Written from what's actually in the repo — no roadmap speculation beyond `esp-firmware/todo.md`.
+
+## What this is
+
+MusicMouse is a DIY, Toniebox-style physical music player for kids, shaped like a mouse and living on a shelf. Small 3D-printed animal figurines (fox, owl, dog, elephant, squirrel, crocodile, rabbit, snowman, puppy — see `hardware/3dprints/figures/`) each carry an RFID tag. Placing a figurine on the mouse triggers an RFID read, which starts that figure's music playlist. The mouse also has a rotary encoder + touch buttons (ears/feet) for volume/skip control, addressable RGBW LED rings with animated effects, and MQTT/Home Assistant integration so a "shelf light" shows up as a smart-home device.
+
+## Repo layout
+
+| Path | What it is |
+|---|---|
+| `python-backend/` | Python host application — the main runtime. Reads RFID/button/encoder events from the ESP32 over serial, drives playback via VLC, sends LED effect commands, bridges to MQTT/Home Assistant. Start here for backend work. |
+| `esp-firmware/` | ESP32 firmware (C++, Arduino framework via PlatformIO). Reads the RFID reader and buttons, drives the LED strips, talks to `python-backend` over serial. |
+| `hardware/` | 3D-print models for the figurines and enclosure (FreeCAD/Blender/OBJ/STL), a Fritzing electronics sketch, datasheets, and `pinout.md` (RFID reader + button-board wiring). |
+| `claude-design/` | An unrelated exploratory web-UI mockup ("Dolphin Beats Music Player" / rebrand concept). Not integrated with the rest of the repo — no build system ties it in. Don't assume it reflects current product direction. |
+| `.vscode/` | Editor settings (C++ header associations). |
+
+There is no top-level README elsewhere in the repo; this file plus `esp-firmware/todo.md` and `hardware/pinout.md` are the only prose docs.
+
+## How the pieces talk to each other
+
+- **ESP32 firmware ↔ `python-backend`**: a length-prefixed binary protocol over serial (`pyserial-asyncio`), implemented in `python-backend/host_driver.py`. Messages are framed with magic tokens (`MAGIC_TOKEN_HOST_TO_FW`/`MAGIC_TOKEN_FW_TO_HOST`) and a `struct`-packed header. The message-ID maps and struct formats in `host_driver.py` must stay byte-for-byte in sync with the firmware's `esp-firmware/src/Messages.h` — there's no shared schema or test verifying this cross-language contract, so a firmware protocol change can silently desync the Python side.
+- **`python-backend` ↔ MQTT/Home Assistant**: `python-backend/mqtt_json.py` exposes the shelf LED strip as a Home-Assistant-discoverable JSON-schema MQTT light (`ShelveLightMqtt`), and `main.py` also calls Home Assistant services directly (e.g. toggling room lights) via `hass-client`.
+
+## Running it
+
+```
+python python-backend/main.py <config_dir>
+```
+
+`main.py` expects `<config_dir>/config.yml` (schema documented in the new `python-backend/config.yml.example` — no real config was previously checked in or documented). In production this is deployed as a systemd service reading music from `/media/musicmouse/`; see `esp-firmware/musicmouse.service` for the unit template — **note its `ExecStart` path (`.../espmusicmouse/host_driver/main.py`) is stale**, referencing the pre-reorg directory layout from before the `bd8925a "Cleaned up repository"` commit moved things to `python-backend/`. Update that path before relying on the service file.
+
+## Config schema (see `python-backend/config.yml.example`)
+
+- `general.{alsa_device, serial_port, hass_url, hass_token, mqtt.{server,user,password}, min_volume, max_volume, volume_increment, button_leds_brightness}`
+- `figures.<name>.{id, colors, media_files}` — `id` is a hex RFID tag id, `colors` is a list of 4 colors (`primary, secondary, background, accent`, each `"#rrggbb"` or `"wNN"`), `media_files` is optional (auto-globbed from the config dir by figure name if omitted).
+
+## Known gaps / notes for agents
+
+- **No automated tests, no lint/formatter config, no CI** anywhere in the repo (neither `python-backend/` nor `esp-firmware/`, aside from a PlatformIO `native` build env for firmware unit testing).
+- `python-backend/audio_analysis.py` and the three chord-recognition notebooks (`C5S2_ChordRec_Templates.ipynb`, `C5S3_ChordRec_HMM.ipynb`, `C5S3_HiddenMarkovModel.ipynb`) are university-course exploratory material (chroma/chord-recognition DSP), **not imported by `main.py`** and not part of the running app. They reference stale personal absolute paths.

-  - thicker top of inner ring, but cutouts for reader [ok]
-  - adjust reader stands position [ok]
-  - bottom for led ring snap-in [ok]
-  - bottom for inner ring [ok]
-    - stands for own "pcb" [ok]
-  - 2 cutouts for cables  [ok]
-  - checks, compared to existing print
-    - same diameter, very slightly smaller
-    - larger overlap of LED ring
-    - minimal wall thickness for led ring top and side
-    - check total height - compare to existing
