about

nx_dr_research_fetch.nx -- SOVEREIGN multi-source web-fetch to STUDY the S-CLASS "disaster recovery / backup / archiving" category, so nx_dr_census grades our DR archive (nx_dr_archive/nx_dr_tree/nx_aw_fetch + verify + receipt) against a REAL sovereign-banked corpus, not hearsay. Same proven pattern as nx_mirror_research_fetch: own TLS-1.3 (nx_https_fetch_follow) + Mozilla CA store, each source -> knowledge/fetched/dr_*.raw (compounds + greppable to CITE). 100% sovereign (own TLS, nx_cc->nxasm, NO curl/wget/gcc). Idempotent have-skip + 4MB cap. Research axes: A STRATEGY/RULES (3-2-1, RPO/RTO, DR) B METHODS (incremental/snapshot/CDP) C TOOLS+APIs (rsync/rclone/bacula/S3-Glacier/Time-Machine) D INTEGRITY/VERIFY (scrub/checksum/bit-rot) E IMMUTABILITY/SECURITY (WORM/air-gap/ransomware/encryption) F DEDUP/EFFICIENCY (dedup/compress/CAS) G CATALOG/RETENTION (rotation/GFS/ZFS/Btrfs snapshots) expect_exit: 0 license_tier: ORIGINAL
