 - Python **3.12+**. Version is computed from git tags via `setuptools_scm` — never edit a version string by hand. To cut a release, tag and push. Tags use **semantic versioning** (`MAJOR.MINOR.PATCH`, e.g. `1.6.0`, `1.6.0-rc.1`).
 - No Makefile, no pre-commit, no lint/format/type-check configured. If you reach for `black`/`ruff`/`mypy`, they aren't wired up here.
 - `dfu-util` binaries are vendored under `omotion/dfu-util/` and shipped with the wheel (see `pyproject.toml` `[tool.setuptools.package-data]`).
+- **libusb ships as exactly four DLLs, all libusb ≥ 1.0.30** (#305): `omotion/_vendor/libusb/windows/{x64,x86}` (VS2022 builds, loaded by pyusb) and `omotion/dfu-util/{win64,win32}` (MinGW builds, loaded by `dfu-util.exe` from its own directory). Source and update steps: `omotion/_vendor/libusb/README.txt`. `tests/test_vendored_libusb.py` fails on an older DLL or on any other libusb binary (static lib, `*-static` tool, dylib) in the package. The macOS `dfu-util` links Homebrew's libusb by absolute path.
 - The laser-driver register baseline (`LASER_PARAMS`, `LASER_PARAMS_FAULT`) and the FPGA register map (`FPGA_MODEL`) are **Python modules** under `omotion/data/`, not data files (#278: nothing editable ships next to the compiled app). `omotion.laser.load_laser_params()` / `FpgaMap()` return deep copies. Locked baseline — loop in the firmware/laser owners before changing a value.
