Summary
Addresses #454
Problem
Stream actions (pause/resume/cancel) waited for the full simulate -> sign -> submit -> poll cycle before updating the UI. Users saw a spinner for 10+ seconds with no visual feedback.
Solution
lib/optimistic-updates.ts(new)Four helper functions:
optimisticStreamStatusUpdate(qc, address, newStatus)— updates the stream's cached info and list entry with the new status. Returns a snapshot for rollback.rollbackStreamStatus(qc, address, snapshot)— restores the previous cached value on error.optimisticWithdrawUpdate(qc, address, amount)— reduces the displayed withdrawable balance. Returns snapshot.rollbackWithdraw(qc, address, snapshot)— restores the previous balance on error.components/stream/StreamActions.tsxrun()now accepts an optionaloptimisticStatusparameter'paused', resume passes'active', cancel passes'cancelled'Behavior
