about

nx_galx_viewadd_lib.nx -- prepend a cid to the gallery's VIEW index. ONE implementation. This is a library, not a copy: nx_galx_viewadd (the CLI) and nx_gen_ingest (the pipeline) both call it. Two writers of a FIXED-WIDTH file that disagreed by one byte would shift every record after the insertion point and scramble 226,576 images -- and it would look like the gallery had been shuffled, not like a write bug. ★ WHEN TWO CALLERS MUST AGREE ON A BYTE LAYOUT, THEY MUST SHARE THE CODE, NOT THE COMMENT. Format (measured): 70-byte records = 69-char cid + '\n', NEWEST-FIRST, so a new gen PREPENDS. Returns 1 = added, 0 = already present, negative = refused/error. license_tier: ORIGINAL
