about

nx_dr_incremental.nx -- CAP-DR-INCREMENTAL: only re-copy CHANGED files (incremental backup, rsync/restic-style). Reads the prior ARCHIVE_RECEIPT.tsv (name<TAB>sha256), and for each manifest source computes sha256; if the receipt already has that name with the SAME hash -> SKIP (unchanged); else copy + verify + record. Writes a fresh receipt covering all current files. Turns an O(all-bytes) re-archive into O(changed-bytes) -- the difference between backing up 957 B and backing up 40 GB of galx every run. argv: [1]=manifest [2]=archive-dir. Additive-safe (reads sources, writes only the archive dir). license_tier: ORIGINAL
