## 📡 Core Nilor Services

Worker Consumer Service

The `worker_consumer.py` script is a background service that runs on each ComfyUI worker. It is responsible for pulling jobs from the central ElasticMQ `jobs_to_process` queue and submitting them to its local ComfyUI instance for processing. This service is essential for the distributed architecture of the system. **Key Responsibilities:** - Continuously polls the `jobs_to_process` queue for new jobs using long polling. - When a job is received, it extracts the workflow data and submits it to the local ComfyUI server. - Normalizes OS-sensitive path formatting in the ComfyUI `prompt` graph (e.g. converts `Flux1/ae.safetensors` ↔ `Flux1\ae.safetensors`) so workflows authored on Linux/Windows run on the current worker OS. - Deletes the job message from the queue upon successful submission to prevent reprocessing. - If submission fails, the message remains on the queue to be picked up by another worker. **Workflow normalization toggle:** - Set `NILOR_WORKFLOW_OS_NORMALIZATION_ENABLED=false` (via environment or `config/config.json5`) to disable this behavior (default: enabled).

## ⚙️ Configuration and Runtime Model The sidecar uses a small, typed configuration loader with JSON5 defaults and optional environment overrides. - **Precedence**: environment variables > `config/config.json5` (controlled by `allow_env_override: true`). - **No hot‑reload**: configuration is loaded once at process start and passed to components. - **Paths/keys**: JSON5 at `ComfyUI/custom_nodes/nilor-nodes/config/config.json5` with `NILOR_*` keys (e.g., `NILOR_COMFYUI_API_URL`, `NILOR_SQS_ENDPOINT_URL`). Secrets (AWS secret) must be set via `.env`. - **Typed object**: loader returns a `NilorNodesConfig` with `comfy`, `worker`, and `hygiene` sections. Pseudocode usage: ```pseudo cfg = load_nilor_nodes_config() # Comfy endpoints http_url = cfg.comfy.api_url + "/prompt" ws_url = cfg.comfy.ws_url + "/ws" # SQS client params endpoint = cfg.worker.sqs_endpoint_url region = cfg.worker.aws_region access_key = cfg.worker.aws_access_key_id secret_key = cfg.worker.aws_secret_access_key client_id = cfg.worker.worker_client_id ``` Current integrations: - `worker_consumer.py`: loads config at startup, reuses a single HTTP session, and uses `cfg.comfy`/`cfg.worker` exclusively. - `media_stream.py`: uses `cfg.worker` for SQS completion notifications.

Environment Variables

The `nilor-nodes` require a `.env` file to be present in the `ComfyUI` directory to configure the connection to the core services (MinIO, ElasticMQ, and the Brain API). To set it up, create a file named `.env` in the root of your `ComfyUI` directory by copying the `.env.example` template. **Instructions:** 1. Create a new file named `.env` in the `ComfyUI` directory. 2. Copy the contents of the `.env.example` file into your new `.env` file. 3. Replace the placeholder values with your actual credentials and endpoint URLs for your local or production environment.
