+# Supervisor Overview
+
+The Supervisor is the job dispatcher layer in Horus. It receives jobs, verifies signatures, and routes them to appropriate runners.
+
+## Architecture
+
+```
+Client → Supervisor → Redis Queue → Runner
+```
+
+## Responsibilities
+
+### 1. **Job Admission**
+- Receive jobs via OpenRPC interface
+- Validate job structure and required fields
+- Verify cryptographic signatures
+
+### 2. **Authentication & Authorization**
+- Verify job signatures using public keys
+- Ensure jobs are from authorized sources
+- Reject unsigned or invalid jobs
+
+### 3. **Job Routing**
+- Route jobs to appropriate runner queues
+- Maintain runner registry
+- Load balance across available runners
+
+### 4. **Job Management**
+- Track job status and lifecycle
+- Provide job query and listing APIs
+- Store job results and logs
+
+### 5. **Runner Management**
+- Register and track available runners
+- Monitor runner health and availability
+- Handle runner disconnections
+
+## OpenRPC Interface
+
+The Supervisor exposes an OpenRPC API for job management:
+
+### Job Operations
+- `create_job`: Submit a new job
+- `get_job`: Retrieve job details
+- `list_jobs`: List all jobs
+- `delete_job`: Remove a job
+- `get_job_logs`: Retrieve job execution logs
+
+### Runner Operations
+- `register_runner`: Register a new runner
+- `list_runners`: List available runners
+- `get_runner_status`: Check runner health
+
+## Job Lifecycle
+
+1. **Submission**: Client submits job via OpenRPC
+2. **Validation**: Supervisor validates structure and signature
+3. **Queueing**: Job pushed to runner's Redis queue
+4. **Execution**: Runner processes job
+5. **Completion**: Result stored in Redis
+6. **Retrieval**: Client retrieves result via OpenRPC
+
+## Transport Options
+
+The Supervisor supports multiple transport layers:
+
+- **HTTP**: Standard HTTP/HTTPS transport
+- **Mycelium**: Peer-to-peer encrypted transport
+
+## Configuration
+
+```bash
+# Start supervisor
+supervisor --port 8080 --redis-url redis://localhost:6379
+
+# With Mycelium
+supervisor --port 8080 --mycelium --redis-url redis://localhost:6379
+```
+
+## Security
+
+- All jobs must be cryptographically signed
+- Signatures verified before job admission
+- Public key infrastructure for identity
+- Optional TLS for HTTP transport
+- End-to-end encryption via Mycelium
