What this claim says

label: Backfill coverage window: ledger 103,252,853 (2026-04-01) → current head
page: /nfts
claim id (yaml): nfts_historical_backfill_range
behavior: MONOTONIC_GROW
Layer 3 source: ripple_public_clio_archive

Risk note

Historical backfill was read from Ripple's public Clio archive (s2-clio.ripple.com) — a third-party pipe. Under SELLABLE_REQUIRES_SOVEREIGN_SOURCE (Fence #2 / Fence #8 in X402_RAILS_DARK_SCOPING.md) this data is filtered OFF the paid tier and stays free forever, disclosed with an amber source-pill at point of display. Re-derivation from our own full-history node is the path to clean title (attorney question 6(d)).
