Errors/Chain errors
StorageOverflow
A chain-side invariant failed; nothing to fix client-side — report it if it persists
Template leftover in the drand pallet for a counter increment overflowing u32::MAX; no current code path raises it. If seen, inspect the drand pallet's stored counters for values near the u32 limit.
Declared by the Drand pallet; it classifies to the semantic code internal.
