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

The Big Picture
A powerful root-only call that directly modifies the total supply counter. Used for protocol-level corrections when actual token distribution does not match the recorded TotalIssuance.
Use Cases
- Correcting accounting discrepancies
- Protocol-level supply adjustments
- Emergency fixes
From Chain Metadata
Adjust the total issuance in a saturating way. Can only be called by root and always needs a positive `delta`.
