Portable signed proof for agent, API, and MCP interactions

PEAC is an open standard for portable signed interaction records across APIs, MCP servers, x402 payment flows, and cross-runtime systems. It enables offline verification and survives organizational boundaries. Use it when local logs are insufficient and external verification is needed.
