jinzijian/EvoTrace was created 2026-08-19 (Apache-2.0, 101 stars, pushed 2026-08-21) and treats local coding-agent trajectories as an asset class. It imports sessions already stored on your machine, picks the ones worth keeping, and compiles them into evidence-backed preference data, replayable coding tasks, RL environments and execution-reward candidates, all local-first with the source data staying under your control. Generated tasks and verifiers stay candidates until they clear documented evidence and Docker validation gates. It is built on DeepSeek Harness and self-describes as early alpha on a developer preview.
