MetriPlane v0.2.0: Open-Source Physical Observability for Workcell Evidence, Replay, and Regression Testing

MetriPlane v0.2.0 is open-source physical observability software for bounded planar workcells. It converts calibrated camera and replay data into metric object state, spatial events, incidents, evidence bundles, operator-review reports, and physical regression tests. The release extends the historical v0.1.3/v0.1.4 camera-to-coordinate and deterministic replay baseline into an observe-only workcell evidence workflow with named assets, trace summaries, spatial contracts, incident grouping, portable evidence bundles, read-only Command Center review, and generated regression tests. The software is local-first and observe-only. It does not control robots or machines, certify safety or quality, identify people, claim marker-free tracking, claim full 3D reconstruction, or claim measured production runtime behavior for Docker, Isaac Sim, ROS 2, or Omniverse unless separately evidenced. The v0.2.0 release includes a dedicated paper evidence package under evidence/paper_v2_0/, including test logs, deterministic replay output, an assembly-cell evidence run, a Cell Truth Report, event ledger, evidence bundle, generated physical regression test, distribution build logs, and checksum/manifest artifacts.
