LinkedOutputSignerMismatch
Check the argument values against the operation schema
The linked order's signer is not the signer who recorded the named provider output. Only the same account can draw against a record; re-sign the consumer with that key.
Declared by the LimitOrders pallet; it classifies to the semantic code invalid_argument.
Declared at pallets/limit-orders/src/lib.rs#L452.
