about

nx_archive_capture_demo.nx -- R4 LIVE end-to-end: browse page3.com AS IT EXISTED in 1997, with its media list. Pipeline: fetch page3.com's REAL Wayback CDX -> cdx_parse -> nx_temporal_index -> query as-of-1997 -> build the raw archived-content URL (web.archive.org/web/<ts14>id_/<original>) -> fetch the ACTUAL 1997 page -> content-address it (CID = polynomial hash, the seg_store key) -> scan its HTML for media references (the per-page media shopping-list). Composes the VERIFIED nx_cdx_parse + nx_temporal_index + our sovereign TLS-1.3 fetch, with retry-on-failure (graceful degradation -- web.archive.org occasionally drops a connection). Live, read-only. license_tier: ORIGINAL
