nx_research_verify.nx

nx_research_verify.nx -- the RESEARCH-VERIFICATION STAGE: batch, autonomous, sovereign claim verification. Upgrades the researcher from "fetch + extract" to "fetch + extract + VERIFY against the cited source" -- the SOTA research behavior. Reads a claims TSV (a researcher's findings), FETCHES each cited source itself over the sovereign TLS-1.3 stack, extracts the real value, and banks a verdict ledger + a summary. Composes the proven single-claim primitive (nx_claim_verify) over a batch; the anti-gaming discipline made a pipeline stage: every claim is CONFIRMED/DISCREDITED against real fetched evidence, or UNVERIFIABLE (never fabricated). INPUT (argv[1] or default knowledge/index/rv_claims.tsv): lines of label<TAB>url<TAB>pattern<TAB>claim_tenths<TAB>tol_tenths OUTPUT knowledge/index/rv_verified.tsv: label<TAB>source<TAB>extracted<TAB>claim<TAB>verdict + a stdout summary. license_tier: ORIGINAL expect_exit: 0
