Engineering benchmarks are turned into implementation-ready CAD plans by drafting `engineering_plan.md` and `assembly_definition.yaml` from approved handoffs. This process validates cost, weight, and motion contracts while maintaining strict consistency with read-only benchmark context.

Trajectory and motion contracts are validated during assembly drafting by applying formula-backed geometry and supporting render inspection. The system derives trajectory data and evaluates simulation evidence to determine overall mechanical feasibility.

Consistency between benchmark definitions and assembly files is maintained by treating benchmark context as read-only input. The planner generates explicit inventory labels and formula-backed geometry to ensure executable artifacts match the original benchmark parameters.

Yes, this engineering planning workflow supports simulation evidence for feasibility checks. It exposes render previews and trajectory derivations alongside formula-backed geometry to validate cost, weight, and motion constraints before finalizing the plan.

You need to draft an `assembly_definition.yaml` when converting an approved benchmark handoff into executable engineering plans. It acts as a drafting contract that defines explicit inventory labels and validates motion constraints for the assembly.

Yes, you can use formula-backed geometry to validate cost and weight contracts. The planner applies these formulas during the revision of engineering plans to ensure internal consistency across drafting contracts and executable artifacts.
