StakeUnavailable

Fund the signing account or reduce the amount; check with `btcli wallet balance`

An unstake or same-subnet stake transfer would dip into stake that is still reserved: the requested alpha exceeds the coldkey's free balance on that subnet after subtracting conviction Lock and any miner registration collateral locked against hotkeys the coldkey owns. Check Lock and MinerCollateral for the netuid; only total stake minus those reservations can move.

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