Explanation

A position can change size, reverse or close while a user signs a stop-loss or take-profit update.

Check expectedPosition, when provided, before updating protection on either provider. Return confirmed child order IDs and leave uncertain submissions unresolved. If a Hyperliquid replacement fails, attempt to restore the original protection and report any loss.

Refused removals preserve surviving protection instead of resuming cancellation during recovery.

Package tests, build and static checks pass. Final Mobile integration and testnet validation are pending.

Requesting changes because a rejected Lighter removal can resume through background recovery and cancel the remaining protection after the position changes. The new dispatch guard stops the foreground cancellation, but that decision must also constrain the durable journal. Please retain reconciliation of already dispatched attempts without allowing recovery to issue the rejected cancellation.
