# pipeline_setup_v4

`pipeline_setup_v4` is a component-level test harness built on top of the `v3` ideas.

Differences from `v3`:

- each YAML case targets a single isolated component;
- results are written next to the suite in `cases/.../test_runs/...`;
- the first supported component is `process_v2_intent_router`.

## Run

```bash
PYTHONPATH=. python -m tests.pipeline_setup_v4.run \
  --cases-dir tests/pipeline_setup_v4/cases/suite_01/process_v2_intent_router/router_only_docs_v2_matrix.yaml \
  --run-name smoke_v4
```

LLM-first router suite:

```bash
PYTHONPATH=. python -m tests.pipeline_setup_v4.run \
  --cases-dir tests/pipeline_setup_v4/cases/suite_02/process_v2_intent_router/router_llm_first_v3.yaml \
  --run-name llm_first_v3
```
