LinkedOutputExpired
The window has closed; restart the flow with fresh state
The provider record's expires_at is in the past, so the output is no longer drawable. Compare LinkedOutputs.expires_at with the chain Timestamp; unused records can be pruned with prune_linked_output.
Declared by the LimitOrders pallet; it classifies to the semantic code expired.
Declared at pallets/limit-orders/src/lib.rs#L456.
