CommitPayloadTooLarge

Ciphertext exceeds the subnet consensus limit (floor(32 KiB / mechanism_count) for Null, 5,000 bytes for Yuma); reduce the row or check epoch_consensus

The encrypted weight commit exceeds the subnet's consensus payload limit. Yuma accepts at most 5,000 bytes; Null accepts at most floor(32 KiB / mechanism_count). Reduce the submitted weight row or check the subnet's epoch_consensus setting.

Declared by the SubtensorModule pallet; it classifies to the semantic code limit_exceeded.

Declared at pallets/subtensor/src/macros/errors.rs#L414.
