We open-sourced the TLA+ and Fizzbee verified spec behind Ursa's storage engine. Verification across ~200K states caught a design bug that years of production missed. We then handed the spec to Claude Code — it produced a working Rust implementation (concurrent producers, compaction, fencing) without back-and-forth. We think verified specs are the best harness for coding agents: open-source the spec, let anyone implement it.

Could you build this?
No Designing and verifying distributed consensus protocols using TLA+ and building crash-resilient Kafka-compatible storage engines requires deep distributed systems research expertise.
What it would actually take: The core system involves formal specification and model checking via TLA+/Fizzbee, coupled with high-performance systems programming in Rust (zero-copy I/O, io_uring, custom page cache/compaction, log-structured storage). The hard parts are proving safety/liveness under network partitions and disk failures, handling concurrency races, and matching Kafka wire-protocol semantics. This demands world-class distributed storage systems and formal verification expertise.
