🔴 HIGH src/main.rs:642 — The environment variable key in the CI workflow is set to __SECRET__ instead of the actual secret name (e.g., OPENAI_API_KEY), causing the API call to fail due to a missing/unresolved secret.
🟡 MED src/main.rs:646 — The run crev review step in the CI workflow uses __MODEL__ as a literal string instead of the dynamically injected model name, preventing the model configuration from taking effect.
