Inputs
Replay sessions or calibrated planar state streams representing tracked workcell assets.
Technical scope
Observe-only physical observability for bounded workcells.
Metriplane works with replayed or calibrated planar workcell state. It turns state into events, incidents, reports, bundles, verification targets, and generated regression checks. The software is camera-compatible for calibrated input, while the public reproduction path is camera-free and replay-based.

Components
Major technical surfaces.
Domain packs
Assembly-cell assets, process steps, contracts, work orders, and workspace configuration.
Event ledger
Physical events and process deviations generated from the replayed state and domain pack.
Incident model
INC-0001 captures the missing required asset, related events, timing, severity, and limitations.
Evidence bundle
Manifest, checksums, incident JSON, event timeline, report, replay command, and scoped excerpts.
Generated regression check
A generated YAML check replays the bounded expectation that the missing tool caused the delay.
Boundaries
Non-claims are part of the design.
The project is research software for evidence review. Its credibility comes from bounded claims, local reproduction, and explicit limits.
Observe-only Planar/tagged-asset scoped Camera-free replay path No robot or machine controlNo safety certificationNo quality-release approvalNo people recognitionNo marker-free tracking claimNo full 3D reconstruction claimNo arbitrary anomaly-detection claimNo successful-remediation claimNo production-factory validationNo factory-wide deployment readinessNo complete external-validation claimNo SoftwareX acceptance or peer-reviewed publication claim
Integration posture
Adapters exist, but runtime claims stay bounded.
The Metriplane repository includes integration surfaces for ROS 2, Omniverse, dashboards, exporters, and local operator review. The public release evidence claim stays centered on the camera-free, local, assembly-cell reproduction path unless separate runtime evidence is linked.
Next step
Point technical questions at the boundaries.
Questions about exact scope, data assumptions, and verification behavior are the best way to harden the artifact.
