xrpl.sidechain.freshness_walker_based

Freshness pill tracks walker_health.last_success_at (not the table's written_at) — SignerListSet rotations are rare, so written_at would misread as 'months ago' when the walker is working

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.

What this claim says

label: Freshness pill tracks walker_health.last_success_at (not the table's written_at) — SignerListSet rotations are rare, so written_at would misread as 'months ago' when the walker is working
page: /sidechain
claim id (yaml): sidechain_freshness_walker_based
behavior: MANUAL_CURATION
Layer 3 source: self-attested-only

Risk note

This is the correct freshness semantic for a rare-event table but a footgun if copied to a high-write table without thought — copying the same pattern to /whales would hide data-write staleness because both walker and table update frequently. Rare-event tables only.
