 44// Parameters:
 45//   - _: Noncrossing implementation-call discriminator; pass 0.
 46//   - rlm: Current realm context forwarded unchanged by the governance proxy; validated before external calls.
 47//   - votingStartDelay: delay in seconds from proposal creation until voting starts
 48//   - votingPeriod: duration in seconds for which voting remains open
 49//   - votingWeightSmoothingDuration: duration in seconds used to smooth voting weight snapshots
 50//   - quorum: quorum percentage applied to the proposal's quorum-weight base
 51//   - proposalCreationThreshold: minimum voting weight required to create a proposal
 52//   - executionDelay: delay in seconds from voting end until execution becomes available
 53//   - executionWindow: duration in seconds during which an executable proposal may run
 54//
 55// Returns:
 56//   - int64: newly stored governance configuration version
