nx_doc_census_real_audit_test.nx

nx_doc_census_real_audit_test.nx -- SUBSTRATE-WIDE V2 audit binary. Walks the REAL nxc2/docs/ filesystem (not a synthetic fixture) and reports current V2 compliance state across the substrate's own ~278 .md docs. This is the substrate's FIRST honest verdict on whether the V2 doctrine the substrate spec'd is being followed. Per [[feedback-never-trust-just-written-until-real-world-harsh- tested]] cardinal: the smoke fixture results (42% on 4 synthetic docs) tell us the LOGIC works; this binary reports what's TRUE across the ACTUAL substrate. Path: hardcoded /mnt/c/Users/elder/nishi-core/nxc2/docs because nx_dir_list requires a path + qemu running under WSL has /mnt/c passthrough. Brittle to other machines; documented limitation. Future: argv-driven root path (queued; nxc2 main() doesn't yet expose argv). Verifies: walk_dir succeeded (rc == 0) n_total > 100 (substrate has ~278 .md; if walk gets <100 the filesystem path is wrong or the walk capped) attestation emits a valid NxEtgEntry Does NOT assert specific compliance % because that changes as docs evolve over time -- the audit reports the CURRENT verdict, not a frozen-in-time gate.
