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

The Big Picture
Ensures some subnet slots are always competitive (not immune). Prevents full subnet immunity lock.
Use Cases
- Ensuring competitive slots exist
- Limiting immunity impact
From Chain Metadata
Sets the minimum number of non-immortal & non-immune UIDs that must remain in a subnet
