# ci_cd_automation - Functional Specification

**Version**: v1.1.9 | **Status**: Active | **Last Updated**: March 2026

## Purpose

Automates the deployment, pipeline management, and rollback capabilities of the platform.

## Design Principles

- **Idempotency**: Pipelines can be re-run safely.
- **Observability**: Every step emits metrics to `pipeline_monitor.py`.
- **Modularity**: Components for building, generating, executing, and deploying are decoupled.

## Functional Requirements

1. **Pipeline Construction**: Programmatic building of CI/CD pipelines via `PipelineBuilder`.
2. **Workflow Generation**: Automatic generation of GitHub/GitLab CI/CD configs via `WorkflowGenerator`.
3. **Execution**: Local execution of pipelines with dependency management and parallelization.
4. **Deployment**: Orchestrate rollout to target environments (dev, staging, production).
5. **Artifact Management**: Versioned storage and retrieval of build artifacts.
6. **Rollback**: Automated reversion on failure thresholds.
7. **Optimization**: Performance analysis and optimization suggestions.

## Interface Contracts

- `PipelineBuilder`: Main entry point for programmatic pipeline definition.
- `WorkflowGenerator`: Interface for platform-specific workflow generation.
- `PipelineManager`: Execution engine for local pipeline runs.
- `DeploymentOrchestrator`: Handles environment state changes and deployments.
- `ArtifactManager`: Interface for build artifact versioning.

## Data Contracts

### Pipeline Configuration Schema

The YAML/JSON schema for pipelines includes `name`, `stages`, `variables`, and `triggers`.
Each stage contains `name`, `jobs`, `dependencies`, and `environment`.
Each job contains `name`, `commands`, `artifacts`, `timeout`, and `retry_count`.

### BuildResult Output

Execution returns a `Pipeline` object with updated `status`, `duration`, and results for each stage/job.
