about

nx_archive_viewer.nx -- make the time-machine VISIBLE. Pulls page3.com's real Wayback CDX, browses as-of-1997, fetches the actual archived page, and EMITS a viewable web artifact under web_assets/archive/: page.html = the reconstructed page (its <img src> rewritten to the archive's image endpoint so it renders) index.html = a dashboard: provenance (bytes/CID/dates), the capture timeline, the rendered page in an iframe, and the raw archived HTML (exactly what we grabbed). Sovereign TLS-1.3. Status-aware retry (handles transient 503 rate-limits) + a DISK CACHE so we fetch each artifact once and never re-hammer the archive. Read-only except the cache + the two output files. license_tier: ORIGINAL
