Animated counter = latest exact permanent-sink balance + trailing-24h verified direct-sink pace between chain refreshes. The stored burn metric remains the exact wallet balance; the projection re-anchors on every new chain observation.
Rolling complete 24h native-burn windows. The curve remains blank for periods whose fee history is still reconstructing.
The permanent-sink balance is read directly from the network-recognised burn address (Songbird includes both documented burn addresses). It stays on the last verified chain balance until the next one-minute refresh; it is never interpolated. The 24h, 7d and 30d direct-sink figures are only shown when an exact chain block checkpoint exists for that lookback. Transaction-fee destruction is reconstructed independently from every indexed block below.
