Jukebox-OS gives AI agents ACID transactions and millisecond time-travel replay

Jukebox-OS: Deterministic time-travel replay and ACID tool sandbox for AI agents

Jukebox-OS is a Rust runtime with Python bindings that records every LLM prompt, token stream, MCP tool call, and filesystem mutation into a cryptographic .jbx tape. It wraps agent side effects in a copy-on-write ACID sandbox, so writes only commit after a verifier passes, and rollbacks leave zero residue. Failed runs can be replayed offline in 0.4ms at zero API cost, or forked at any frame with a different model or prompt. A circuit breaker trips on runaway loops.
