Lean 4 applied to max-plus (tropical) algebra to resource-aware type systems for compositional worst-case bounds. Provides a reusable resource-grade axis with parametric transport, a no-go theorem refuting universal protocol interoperability (hub_ceiling); separation proofs distinguishing tropical instances from finite {0,1,ω} reifications & Echosh
