OpenResearch (orx) is alphaXiv's local-first research workspace: a single Rust binary that turns Claude Code, Codex, OpenCode, or Cursor into research agents that review literature, form hypotheses, run experiments, and produce artifacts. It organizes work as a git-native experiment tree under a fixed run contract, drives experiments through a repair/refill/promote/stop autoresearch loop, and treats run logs and manifests as the only evidence. Written from a close read of the v0.2.3 source and a hands-on run of the bundled nanochat demo.
