MLIR
MLIR matters because EngineeringOS may eventually need more than one lowering stage between authored engineering language and target-ready compiled outputs.
How EngineeringOS Uses It
EngineeringOS should study MLIR for multi-level IR design, staged lowering, dialect boundaries, and extensible transformation pipelines. Those ideas are useful if the platform grows beyond one canonical IR layer into richer domain-specific intermediate forms.
Boundary
MLIR should remain an inspiration unless the implementation genuinely benefits from its complexity. The draft's method is to borrow the architecture where needed, not import complexity prematurely.
