This diagram shows the call execution flow: starting with force_transfer, passing through validation
(signature, nonce, mortality, fee payment), then pre-dispatch checks, followed by dispatch which emits events: Transfer and modifies storage: Account, and finally post-dispatch where ExtrinsicSuccess is emitted and fees are settled.

The Big Picture
Like transfer_allow_death, but callable only by root and allows specifying the source account. Used when funds need to be moved without the source account signing the transaction.
Use Cases
- Emergency fund recovery
- Protocol-level transfers
- Correcting stuck balances
From Chain Metadata
Exactly as `transfer`, except the origin must be root and the source account may be specified. ## Complexity Same as transfer, but additional read and write because the source account is not assumed to be in the overlay.
