Implement Contract Monitoring and Self-Healing Pipelines

[digitalrisedorset]

Self-Healing Widget Platform

Problem

ReactEdge currently provides widget deployment, validation, testing, and observability capabilities.

When a widget contract becomes invalid, incomplete, inaccessible, or inconsistent with the widget's expectations, the widget may fail to render correctly and human intervention is required to identify and resolve the issue.

As the platform grows, manually monitoring and maintaining widget contracts becomes increasingly costly and difficult.

Goal

Introduce a self-healing capability that continuously monitors widget contracts, detects failures and anomalies, and automatically executes remediation workflows whenever possible.

The objective is to allow widgets to recover from common issues without requiring human intervention.

Vision

Build a platform capable of:

• Observing widget behaviour
• Detecting contract issues
• Diagnosing likely root causes
• Executing remediation actions
• Verifying successful recovery
• Escalating only when automated recovery is not possible

Initial Scope

The first implementation will focus on contract health.

The platform will:

1. Validate widget contracts
2. Detect broken validation rules
3. Generate structured incidents
4. Execute remediation pipelines
5. Re-validate contracts after remediation
6. Record all actions through OpenTelemetry traces

Example Use Cases

Missing Required Field

Contract:

{
  "data": {}
}

Detection:

• Zod validation fails

Remediation:

• Restore last known valid contract
• Request regeneration from source system

Verification:

• Contract passes validation

---

Broken Asset Reference

Contract:

{
  "image": {
    "src": "https://example.com/missing.jpg"
  }
}

Detection:

• Asset unreachable

Remediation:

• Restore previous asset
• Re-fetch source asset
• Replace with fallback asset

Verification:

• Asset returns HTTP 200

---

Invalid Contract Metadata

Detection:

• Unexpected structure
• Missing required metadata

Remediation:

• Regenerate metadata
• Reconcile against schema

Verification:

• Contract passes validation

Acceptance Criteria

• Widget validation failures create incidents
• Incidents are observable through OpenTelemetry
• Remediation pipelines can be registered per widget
• Remediation pipelines can be registered per validation rule
• Platform automatically retries validation after remediation
• Successful recoveries are logged
• Failed recoveries are escalated for manual review

Future Enhancements

• AI-assisted diagnosis
• AI-generated remediation plans
• Runtime self-healing
• Deployment self-healing
• SSR self-healing
• Infrastructure self-healing
• Autonomous recovery agents
