- HuggingFace Spaces deployment must treat `PORT` as runtime-configurable and wire both `HEALTHCHECK` and `uvicorn` startup to `${PORT:-8000}` for local/HF parity *(F007)*
- Training notebooks should include an explicit `SQLEnvClient` connect/reset/step smoke test before GRPO runs to fail fast when environment connectivity is broken *(F007)*
- OpenEnv builds that depend on `ghcr.io/meta-pytorch/openenv-base` should assume GHCR authentication is a prerequisite in CI or local locked-down environments before `uv run openenv build` *(F007)*
- Deployment readiness for OpenEnv Spaces is only complete after a successful authenticated `uv run openenv push` to the target HuggingFace Space, not just a local Docker build *(F007)*
