AXIOM MCP

A transactional write gate for coding agents that sits between the agent and the repository. It judges every write and shell command before execution, compiles changes into a canonical manifest, and applies them atomically with digest confirmation. It supports session undo, explainable decision journals, and DSSE signatures for provable integrity.
