Execution Fabric & Hermes

Purpose

Perform approved work through reliable, observable, reconciled execution.

Flow

Intent
→ Capability
→ Immutable Execution Plan
→ Governance
→ Approval when required
→ Hermes
→ Tool / API / MCP / Workflow
→ Source System
→ Receipt
→ Reconciliation

Hermes

Hermes is the execution/orchestration runtime.

It is not the product's canonical memory.

It receives governed work and coordinates execution.

Execution requirements

• tenant isolation;
• idempotency;
• correlation;
• causation;
• retries only when safe;
• timeout handling;
• dead-letter handling;
• receipts;
• audit;
• reconciliation.

Ambiguous result

Unknown result
→ Stop automatic retry
→ Reconcile source state
→ Continue only after state is known

Outcome

Technical execution success is not sufficient. Business outcome must be verified/reconciled.
