Mechanism-resolved, calibration-pending. The full spatial immune scene at the reduced-scale side-30 patch, coupled bidirectionally to the hybrid 10-species Price-2015 global ODE (integrated once per MCS). Epithelial H/I cells, the macrophage/NK/CD8 clusters, and the ▨ dormant recruit-reserve pool (parked in the medium margins, activated by ODE-driven inflow) all share one lattice. At this scale (η≈1.4e-04) the coupling MAGNITUDES are uncalibrated — dynamic sig_1 collapses ~1e-6 vs the retired stub (2.44) and recruitment stays too weak to engage naturally. Mechanisms wired correctly; unit-scale calibration deferred to Increment 9.
