about

nx_zip_extract1.nx -- sovereign single-entry ZIP extractor (STORED or DEFLATE). Reads a .zip whose FIRST local file entry is the payload (the shape HF ships for small single-file dataset archives, e.g. whyen-wang/coco_keypoints/data/ keypoints_validation.zip -> keypoints_validation.json), inflates it with the shipped sovereign nx_deflate_inflate, and writes the decompressed bytes out. This is the "eat the debt" companion to the main-API dataset fetch: the HF datasets-server (datasets-server.huggingface.co) 503s our client for EVERY route (its own /healthcheck 503s -> HF-side/edge, not a fetcher bug), so dataset CONTENT is reached via the WORKING main API (tree -> LFS resolve -> file) and decompressed here. 100% sovereign: own TLS fetch (upstream) + own DEFLATE (here); the only non-Nishi input is the fetched archive bytes. Config (relative to nxc2 cwd; the build/run launcher does not forward argv): data/mp_zip_in.txt -- path to the .zip on disk data/mp_zip_out.txt -- path to write the decompressed entry nx_safety_envelope: intended_use: decompress a fetched dataset archive (offline, local file) sil_target: SIL1 verdict: NOT_YET_EVALUATED genealogy_id: pkware/appnote + ietf/rfc_1951 lineage_id: nx_zip_extract1_v1
