Casys Digital Thread
Local first engineering control plane that lets AI agents take a design from brief toward checked evidence, using registered deterministic engineering operations and a read only workbench.
What it does and how it connects
Casys Digital Thread is an experimental, local first engineering control plane. It turns reviewed project intent into traceable technical artifacts and bounded evidence through registered operations: deterministic engineering tools compute, humans retain consequential decisions, and the Workbench projects persisted state read only. The README marks it active research and alpha, with partial coverage, and states a successful tool run is not by itself a whole product, manufacturing, conformity, release, or certification verdict.
The engineering loop runs from human intent and consequential decisions, to agent proposed registered operations, to server selected parsing, lowering, provider, runtime, and recovery, to exact artifacts, persisted evidence, and a bounded verdict, projected in the read only Workbench. The project supports idea first, CAD first, and reverse engineering entry paths, and keeps SysML, geometry, simulation, measurement, evaluation, and manufacturing evidence as distinct records.
Local first means project state, the control plane, the Workbench, and registered local execution paths are designed to live on the operator machine, though agent providers, ERP systems, container registries, or other reviewed integrations may still use the network. The README names an optional ERPNext bridge and states agents must start with the repo AGENTS.md and the agent workspace reference.
