about

nx_dr_archive.nx -- CAP-DR-ARCHIVE: sovereign disaster-recovery archiving. Copies critical NAS state to a SEPARATE device (a local drive that is NOT the NAS) + verifies BYTE-IDENTITY + records a sha256 receipt -- killing the DATA SPOF without a failover host. Data-driven: a manifest (source-path <TAB> archive-name) is the SSOT of what to protect. Composes rep_in_sync (byte-identity proof), nx_sha256 (integrity fingerprint), slk_* (manifest parse). Idempotent (each run = a fresh, verified snapshot). Additive-safe: READS the NAS, WRITES only the archive dir. argv: [1]=manifest-path [2]=archive-dir (on a separate drive, e.g. /mnt/d/nishi-archive) license_tier: ORIGINAL
