Global Configuration Updates (Backbone Re-wiring)

Objective: To update the shared operational infrastructure (Billing, Logging, or Auth providers) for all services within the swarm simultaneously.

Prerequisites

• An established application with active Domain Services.
• The Master Private Key for authorization.

The Protocol Workflow

1. Configuration Selection: The developer determines a new backbone service URL (e.g., switching from old-billing.com to sovereign-pay.io).
2. The Backbone Update Request: The developer sends a signed PATCH request to the App Registry to update the Operational Context.
3. Registry Verification: The Registry validates the signature against the Master Public Key.
4. State Transition: The Registry updates the operational_context object for the app_id.
5. Propagation (The Signal): The Registry notifies all bound Domain Services that their configuration has changed. This is handled via:
   • Outbound Webhooks: The Registry pushes the new config to registered service endpoints.
   • Reactive Refresh: Services detect a “Config-Epoch” mismatch on their next interaction and fetch the update.

    "context": "backbone_update"
  },
  "signature": "d4e5f6a7b8c9..."
}

Service-Level Adoption

Once the App Registry updates the context, Domain Services perform the following logic:

• Handshake Verification: The service receives the new billing_provider_url.
• Re-Binding: The service may perform a “Mini-Handshake” with the new provider to establish a reporting channel.
• Cutover: The service begins routing all telemetry and billing data to the new URL immediately.
