1// nx_ecosysdesign_gate.nx -- EXECUTABLE evidence for the ecosysdesign compare domain (honesty ratchet 2// 2026-07-16: move a claim-only domain to evidence-backed). Re-measures the LIVE dependency graph and 3// asserts the matrix's load-bearing claims -- NOT a stored number: the store is loaded + queried every run, 4// so if the design erodes the gate goes RED and the compare page fails. Proves: (1) the graph loads at scale, 5// (2) nx_syscalls IS the libc-pattern universal base (max fan-in, huge reach, tiny own-imports), (3) nx_tier 6// is a true gen-0 root (imports nothing), (4) the base's blast radius is the >90% "everything descends" 7// property.
