export_permission_history
Documentation for eth_defi.hyperliquid.permission.export_permission_history function.
- export_permission_history(database_paths, destination, *, observations=None)
Export separate source observations from closed scanner databases.
Repeated backup copies deduplicate only identical observation IDs. A reused ID with different contents is a hard error instead of silent precedence.
- Parameters
database_paths (list[pathlib.Path]) – Existing daily/HF scanner files opened read-only.
destination (pathlib.Path) – Sidecar Parquet path; replaced atomically.
observations (Optional[pandas.DataFrame]) – Already-read observations from active scanner owners; avoids reopening with a different DuckDB configuration.
- Returns
Combined exact observation frame, including explicit uncertainty.
- Return type
