nx_ecomat_trend.nx -- "are we actually advancing, or just declaring more frontiers?" Reads the durable maturity ledger and splits its movement into ADVANCEMENT (an existing domain climbed a rung -- measured exactly across spans where the cohort was stable) and EXPANSION (new domains declared, which raise the bar and therefore DEPRESS the sum_cur/sum_bar headline). Why this organ exists: the headline alone is directionally misleading by construction. The same ledger that reads "460 -> 434 permil, we regressed" also says sum_cur rose 47 -> 53. Both are true; only the decomposition tells you which one is capability. argv[1] = ledger path (default knowledge/status/ecosystem_maturity.log) verdict=GREEN/RED reports the INSTRUMENT. The ecosystem's own state is the separate `finding=` field -- a truthful FLAT must never be reportable as a broken gauge. license_tier: ORIGINAL No hw writes (Rule 26).
