XDMOD — Cross-Domain MODeling

XDMOD is a method and toolset for model-based systems engineering across domains (systems, software, electrical, mechanical, integration), with traceability from stakeholder needs to verification evidence. It is used through a west workspace that has this repo as a project (D66). The robot arm (robarm-* repos) is its worked example.

Folder	What
curatrix/	the workspace command layer and checker, curatrix (README)
needs/needs_config.toml	need types, link types per owning type, fields, schema rules (shared by every document)
sysml/	SysML v2 library: trace metadata (NeedRef, Trace), view metadata (XdView)

launch/CLAUDE.md	workspace rules for agents; copied to the workspace root by the bootstrap (D69)
workflows/	caller templates for the reusable workflow in .github/workflows/curatrix-check.yml
tools.yaml, requirements.txt	pinned tools and pip packages for xdmod's tooling and every doc build (D19)

Quick start (in a workspace whose manifest lists xdmod):

robarm-manifest/scripts/bootstrap.sh --role ee      # .venv, west, curatrix, then `curatrix bootstrap`
curatrix doctor
curatrix check robarm-ee --stage local
