Lifecycle & Contract Repair Toolkit
Repair the hidden lifecycle and contract mismatches that create inconsistent behavior across modern applications. This bundle covers audit-event contracts, cache invalidation, cart merging, environment drift, feature-flag lifecycles, invitation flows, money-amount handling, and optimistic-lock behavior. Use it when individual components appear correct but failures emerge at boundaries, retries, stale state, concurrent updates, configuration changes, or incomplete lifecycle transitions.
Works with every agent that reads SKILL.md — Claude Code, Cursor, Codex CLI, Gemini CLI, GitHub Copilot, Windsurf, OpenClaw, and more.

Align the audit event contract between the UserMutation service and the transactional outbox to ensure actor IDs are consistent and failed attempts are captured.
Your agent does
I have updated UserMutation.ts to use the AuditedAction interface and modified the OutboxWorker to include the actor_guid. Added a test case in audit_contract_test.ts to verify failure recording.
