Respawn – an undo button for AI agents (Rust, local-first, no cloud)

respawn is a beta tool that versions a directory tree as a content-addressed snapshot graph, letting you revert any file state with atomic writes and BLAKE3-verified integrity. Built for the "agent era," it wraps autonomous processes with snapshot-before, revert-on-failure semantics, supports encrypted LAN sync via Noise protocol, and maintains a tamper-evident audit log with ed25519-signed anchors — all with no central server.
