+# Workflow Orchestration: Development and Deployment Guide
+
+## 1. Goal and Scope
+
+The purpose of this document is to provide a comprehensive guide for participants to create, manage, and update workflows within the Simpl-Open orchestration platform. 
+By following a *code-first approach*, developers ensure consistency, traceability, and reliability across all environments.
+
+## 2. Local Development
+Development must always begin in a local environment. This allows developers to rapidly iterate, test business logic, and validate DAG (Directed Acyclic Graph) structures without impacting production data.
+
+### 2.1 Project Layout
+To ensure compatibility with the Simpl-Open platform, every Dagster code location must adhere to the following directory structure:
+```text
+project-root/
+├── dagster_code_location/
+│   ├── jobs/           # Executable workflows
+│   ├── ops/            # Individual functional units (business logic)
+│   ├── resources/      # External connections (Object storage, APIs, etc...)
+│   └── repository.py   # Central entry point for the code location
+├── tests/              # Unit and integration tests
+├── Dockerfile          # Containerization instructions
+├── pyproject.toml      # Dependency management (Poetry/Pip/UV)
+└── README.md           # Documentation
+```
+
+### 2.2 Code Examples (Ops, Jobs, and Definitions)
+The orchestration logic should be modular. Here is a practical example of how to construct a workflow.
+
+**1. Defining Ops (ops.py)**  
+Ops are the core units of computation. Keep them focused on a single task.
+```python
+from dagster import op
+
+@op
+def fetch_raw_data() -> list:
+    """Fetches raw data from an external source."""
+    return [{"id": 1, "value": "A"}, {"id": 2, "value": "B"}]
+
+@op
+def process_data(data: list) -> dict:
+    """Transforms raw data into an aggregated format."""
+    return {"processed_count": len(data), "status": "success"}
+```
+**2. Assembling Jobs (jobs.py)**  
+Jobs link ops together to form a dependency graph (workflow).
+```python
+from dagster import job
+from .ops import fetch_raw_data, process_data
+
+@job
+def data_processing_job():
+    """A workflow that fetches and processes data."""
+    raw_data = fetch_raw_data()
+    process_data(raw_data)
+```
+**3. Registering Definitions (repository.py)**  
+This file acts as the entry point for the Simpl-Open orchestration platform to discover your code.
+```python
+from dagster import Definitions
+from .jobs import data_processing_job
+
+# The platform will load this Definitions object
+defs = Definitions(
+    jobs=[data_processing_job]
+    # You can also declare schedules, sensors, and resources here
+)
+```
+
+### 2.3 Best Practices & Constraints
+- **Separation of Concerns**: Keep orchestration logic (how ops connect) strictly separate from heavy business logic (which should ideally live in separate Python modules/classes).
+- **Naming Conventions**: Use snake_case for jobs and ops. Code locations should be named based on the domain they represent (e.g., inventory_sync_service).
+- **Dependency Management**: All dependencies must be explicitly declared in pyproject.toml or requirements.txt.
+- **Environment Agnosticism**: Avoid hardcoding credentials. Use environment variables to handle configuration.
+
+## 3. Publishing to Production (Gitea)
+
+Once the local validation is complete, the code must be published to the centralized Gitea repository.
+
+1. **Repository Hosting**: All workflows are stored in Gitea instances within the agent environment.
+2. **Versioning**: Workflows are versioned using Git. Each version of a workflow must correspond to a specific Git commit.
+3. **Artifact Generation**: Workflows are packaged as Docker container images.
+    - Images must be pushed to the Gitea Integrated Container Registry.
+    - **Tagging Policy**: Use semantic versioning or Git commit SHAs. Avoid using the latest tag in production to ensure idempotency and easy rollbacks.
+
+## 4. Review and Approval Process
+
+To maintain high-quality standards and security, no code is deployed directly to the main branch.
+
+1. **Feature Branching**: Developers must push their changes to a dedicated feature branch.
+2. **Pull Request (PR)**: Open a Pull Request in Gitea from the feature branch to the main branch.
+3. **Peer Review**: At least one developer (other than the author) must review the code.
+    - Reviewers check for logic errors, security vulnerabilities, and adherence to the standards defined in Section 2.
+4. **Approval**: Once comments are addressed and the reviewer provides an "Approve" status, the PR can be merged.
+
+## 5. Production Deployment
+
+After the code is merged and the artifact is published, the final step is deploying to the orchestration platform.
+
+### 5.1 Deployment Pipeline
+
+The deployment follows these automated steps:
+
+1. **CI/CD Trigger**: A merge to the main branch triggers the CI pipeline.
+2. **Image Build**: The pipeline builds the Docker image and pushes it to the Gitea Registry.
+3. **Manifest Update**: The deployment configuration (e.g., Helm values or Kubernetes manifests) is updated to reference the new image tag.
+4. **Platform Reload**: The Simpl-Open orchestration platform (Dagster) is notified of the change.
+
+### 5.2 Verification
+
+To confirm a successful deployment:
+
+- **Dagster UI**: Navigate to the "Deployment" or "Code Locations" tab. Verify that the loaded image tag matches the latest Git commit.
+- **Health Check**: Trigger a "Test Run" of the job in the production environment using a limited data slice.
+- **Logs**: Monitor the initialization logs in the Dagster daemon to ensure the code location was loaded without schema or dependency errors.
