Runs all unit tests securely without secrets (`persist-credentials: false`). 2. Cleans up execution states and isolates failure markers to runner temp. 3. Obtains standard PR git diff using the base SHA. 4. Generates a fully batched, labeled AI code review using the OpenRouter `cohere/north-mini-code:free` model from a trusted base branch checkout. 5. Employs prompt injection security notices. 6. Posts and automatically updates/deduplicates CodeRabbit-style reviews on the Pull Request. 7.
