-# IPM native integration (app.ipm)
-
-This folder contains the Python wrapper that calls the native refifc libraries.
-
-Goals
-- Centralize the Python wrapper under `app/ipm` so application code can import `app.ipm.simple_refrig_api`.
-- Provide a clear location for native binaries (DLLs for Windows, .so for Linux).
-
-Where to place native binaries
-- Windows (local/dev): place DLL files in `app/ipm/lib/windows/`.
-- Linux (container/production): place .so files in `app/ipm/lib/linux/`.
-
-The wrapper `app/ipm/simple_refrig_api.py` will look first in `app/ipm/lib/<platform>` (`windows` or `linux`) and fall back to the package directory if nothing is found.
-
-Do NOT commit native binaries
---------------------------------
-Native binaries should not be committed to the repo (size, licensing, portability). The repo contains a `.gitignore` rule excluding `app/ipm/lib/windows/*.dll` and `app/ipm/lib/linux/*.so`.
-
-CI/CD
-- Store binaries in a secure artifact repository (releases, internal storage, S3, etc.).
-- During CI, download them and copy into `app/ipm/lib/<platform>` before building the image or deploying.
-
-Quick local test
-1. Copy the binaries into the correct folder (e.g. `app/ipm/lib/windows/refifc.dll`).
-2. Test locally:
-
-```powershell
-.venv\Scripts\python -c "import app.ipm.simple_refrig_api as s; r=s.Refifc('R290'); print('hsl_px exists', hasattr(r,'hsl_px'))"
-```
-
-Best practices
-- Avoid committing binaries in Git.
-- Record the exact origin and version of native binaries in release notes.
-- Provide small helper scripts (`scripts/copy-ipm-libs.*`) to automate copying binaries into build environments.
-
-For French documentation see: [README_fr.md](README_fr.md)
