The team's `.env` and `docs/reference/watsonx_access.md` document
`WATSONX_API_KEY` / `WATSONX_PROJECT_ID` / `WATSONX_URL`, but newer
litellm WatsonX provider versions (≥ 1.81.x as observed in the team
`.venv-insomnia`) read `WX_API_KEY` / `WX_PROJECT_ID` / `WX_URL` and
fail with `"Watsonx project_id and space_id not set"` if only the
`WATSONX_*` names are set.
This helper copies `WATSONX_<NAME>` into `WX_<NAME>` when `WX_<NAME>`
is unset. Caller-provided `WX_*` values win (no clobber). It mirrors
the long-standing `WATSONX_API_KEY` ↔ `WATSONX_APIKEY` bridge in
`scripts/run_experiment.sh:290`.
Used by every Python entry point in this repo that drives a
`watsonx/...` LiteLLM model:
- scripts/generate_scenarios.py (PS B generator → litellm.completion)
- scripts/aat_runner.py (AaT runner → Agents SDK LitellmModel)
- scripts/judge_trajectory.py (judge → litellm.completion)
The bash wrapper `scripts/run_experiment.sh` does the same alias inline
so subprocess paths (replay loop, batch mode, etc.) inherit the WX_*
names without going through Python.
