nx_ecomat_domtrend_live_gate.nx

nx_ecomat_domtrend_live_gate.nx -- runs the EXACT per-name attribution against the REAL per-domain ledger and proves its invariants on live data. The fixture gate (nx_ecomat_domtrend_gate 17/17) proves the logic. This proves it on the artifact that actually exists -- because a decomposition only ever exercised on synthetic input is the "gate passes on synthetic data" calibration failure already filed at sev8. T4 is load-bearing: CONSERVATION. Every level of movement must land in exactly one bucket, so advance + declared + retired must reconcile with the endpoint delta. If attribution ever double-counts or drops a domain, that identity breaks and this goes RED. license_tier: ORIGINAL No hw writes (Rule 26).
