ar vs cockpit

ar: Agent Receipts is an open protocol for generating cryptographically signed audit trails for AI agent actions. It provides SDKs in Go, TypeScript, and Python, plus an MCP proxy that intercepts and signs agent tool calls using Ed25519 signatures. The receipts can be verified independently, enabling accountability and traceability in agentic systems.; cockpit: Cockpit runs Claude Code as a server you can reach from any browser. You get Claude Code on your phone, many sessions at once that survive closing the browser, and scheduled cron-style runs.
