CAD and Fabrication Workflow
Route a part, assembly, drawing, robot description, simulation model, or fabrication handoff through explicit units, editable source, geometry/semantic validation, visual inspection, and a separate physical-action authority gate. Source: pinned

Contract
The input must identify the intended artifact, units, critical dimensions or constraints, assumptions, and whether the job ends at a digital artifact, vendor preflight, upload, or physical execution. The workflow routes by deliverable rather than loading all CAD skills into every context.
| Stage | Output |
|---|---|
| Frame | Frozen brief, units, tolerances, intended use, and authority ceiling |
| Route | Smallest required skill subset and dependency preflight |
| Build | Editable source plus primary artifact; STEP-first unless the format contract says otherwise |
| Validate | Machine checks for geometry, frames, collisions, semantics, slicing, or vendor constraints |
| Inspect | CAD Viewer snapshots/live review and explicit unresolved assumptions |
| Handoff | Digital deliverable, conservative vendor report, or dry-run physical plan |
| Record | Artifact hashes, commands, proof, limitations, and reusable corrections |
Authority boundary
Generating and inspecting local files is allowed within the task's write scope. Network downloads, vendor uploads, purchases, machine motion, and printer execution are separate effects. bambu-labs stays dry-run unless the user authorizes the exact target; upload requires --execute, and print start additionally requires --confirm-start-print. A plausible render is not manufacturing proof.
Completion proof
Completion requires the editable source, primary output, deterministic validation results, visual inspection, units/assumptions, and hashes or stable paths. Robot work also needs topology/frame/limits/collision semantics; fabrication work needs the named material/profile/process constraints. If dependencies are missing, the workflow returns a specific preflight blocker rather than claiming a partial artifact is ready to manufacture.
