Struct IceCommands 

pub struct IceCommands<'a> { /* private fields */ }

Break-glass operator surface. Constructed via DeckClient::ice; each method returns an IceProposal that must be simulate()d before commit() per the plan’s locked decision #4 (blast-radius simulation is mandatory before any ICE commit).

Implementations

impl<'a> IceCommands<'a>

pub fn freeze_cluster(&self, ttl: Duration) -> IceProposal<'a>

Propose a cluster-wide freeze. The returned IceProposal must be simulated then committed.

pub fn flush_avoid_lists(&self, scope: AvoidScope) -> IceProposal<'a>

Propose flushing avoid-list entries under scope. See super::meshos::ice::IceActionProposal::FlushAvoidLists for the three scope semantics.

pub fn force_evict_replica( &self, chain: ChainId, victim: NodeId, ) -> IceProposal<'a>

Propose force-evicting victim from chain bypassing the scheduler’s rebalance cooldown. Only the chain’s elected leader emits the resulting RequestEviction action; non-leader nodes fold the admin event silently.

pub fn force_restart_daemon(&self, daemon: DaemonRef) -> IceProposal<'a>

Propose force-restarting daemon by resetting its supervisor backoff gate so reconcile fires StartDaemon on the next tick. No-op if the daemon is already in Idle backoff state.

pub fn force_cutover(&self, chain: ChainId, target: NodeId) -> IceProposal<'a>

Propose force-placing chain on target, bypassing the placement scorer. Only the chain’s elected leader emits the resulting RequestPlacement action with target: Some(target); non-leader nodes fold silently. No-op if target is already a holder.

pub fn kill_migration(&self, migration: MigrationId) -> IceProposal<'a>

Propose aborting an in-flight migration. The wire-form substrate plumbing records the commit on the audit ring; the dispatcher hookup that finds the running migration and stops it is future substrate work, so until that lands the proposal commits without actually halting the migration. The audit trail tracks the operator’s intent regardless.

pub fn thaw_cluster(&self) -> IceProposal<'a>

Propose cancelling an in-effect cluster freeze.
