GammaDepositSpenderMismatch
The deposit already names another spender (`btcli gamma show`); mint without `--spender` or `--service-hotkey`, or change it with `btcli gamma set-spender` first
A mint named a spender, but the gamma deposit it credits already names another. A named spender opens a new deposit and must match an existing one. Mint without naming one, or change the deposit's spender with set_gamma_deposit_spender first.
Declared by the SubtensorModule pallet; it classifies to the semantic code invalid_argument.
Declared at pallets/subtensor/src/macros/errors.rs#L481.
