 Normalized DeFi liquidation events decoded from public on-chain logs.
 
+## Current Scope
+
+- **Coverage:** Ethereum Aave liquidation events captured from public logs.
+- **Best for:** Liquidation-pressure monitoring, stress-event labeling, and cross-checking DeFi liquidation bursts against perp market data.
+- **Cadence:** append-only partitions, normally refreshed by the Chainticks nightly publisher.
+- **Timestamps:** UTC ISO-8601 strings when available. Null timestamp fields mean the source event did not include a timestamp at collection time.

 Rows must have `source_kind` in `['on_chain_event']`. Chainticks does not publish venue REST/API resale data in this dataset.
 
+## Known Limitations
+
+This is a sparse bootstrap feed. Absence of rows should not be treated as proof that no DeFi liquidations occurred globally.
+
 ## Agent Prompt Snippet
 
 Use this dataset as append-only market context. Read `LATEST_DATE.txt`, inspect `_schema.json`, then load the relevant Parquet partition. Treat timestamps as UTC and preserve `source_kind` in downstream analysis.
