xrpl.price_data.never_touches_node

Route never touches the XRPL node — snapshot-based read only, so a stalled node does not slow /price-data

yellow Public-infrastructure dependent OR no independent cross-check path yet. Free-tier only until Batch B walker migration lands (post-soak, ~2026-08-31) and/or an independent verification walker is wired for this series.

Machine-readable status: /claims/xrpl.price_data.never_touches_node.json or send Accept: application/json on this URL. URI is permanent — safe to cite.

What this claim says

label: Route never touches the XRPL node — snapshot-based read only, so a stalled node does not slow /price-data
page: /price-data
claim id (yaml): price_data_never_touches_node
behavior: MANUAL_CURATION
Layer 3 source: self-attested-only

Risk note

Load-bearing perf property. If the route ever falls back to a live RPC read on cache-miss, page-load-under-node-load becomes possible — same class of failure that pushed /whales toward the warmer pattern. Cache-miss must resolve to snapshot-null, not to RPC.

Evidence — code paths that back this claim

app.py:price_data() — fetch_oracle_snapshot_cached() only
oracle_snapshot.py — no rippled RPC in cached read path
