+# Python Worker
+
+This is the first, compatibility-preserving ownership migration of the shared
+FastAPI worker from the n8n Compose project into Infra.
+
+The service deliberately keeps the existing container name, port, local image,
+source/state mounts, files mount, and `n8n_default` network. Therefore n8n and
+the OGame Agent continue to use `http://python_worker:8000` without workflow
+changes. The absent `playwright_chrome` runtime is not migrated; current OGame
+automation uses the existing CDP browser endpoint.
+
+Host-specific, non-secret runtime values are captured during cutover in the
+ignored `python-worker/runtime.env` file with mode `0600`. The 921 MB source and
+state directory remains at `/volume2/docker/n8n/python_worker` for this phase so
+rollback does not require a data copy.
+
+The local `n8n-python_worker` image is transitional. A later reviewed change
+must add a pinned production Dockerfile and remove boot-time package installs
+before the old image can be considered reproducible.
