NorskManager.getNodeIdleExpiry() method
What idle expiry applies to a node: idleExpiryMs is the override as set (0 = none), effectiveIdleExpiryMs is what the reaper will actually apply — the override when one is set, otherwise the daemon-wide value.
Signature:
getNodeIdleExpiry(nodeId: NodeId): Promise<{
idleExpiryMs: number;
effectiveIdleExpiryMs: number;
}>;
