Phase 1: Implement Audit & Event Log

[monthop-gmail]

Objective

Implement the audit and event log schema for observability and trust (RFC-0003).

Scope

• Define core event types: JOB_CREATED, STATE_TRANSITION, GOVERNANCE_DECISION, TASK_ASSIGNED, EXECUTION_STARTED, EXECUTION_FAILED, JOB_COMPLETED
• Required fields: event_id, job_id, event_type, timestamp, source
• Events are append-only (no mutation, no deletion)
• No silent state change — every transition emits an event
• In-memory event store for v0.1
• Unit tests for event creation and immutability

Out of Scope

• Metrics backend selection
• Dashboard UI
• Correlation IDs (future work)
