A zap answered by two tabs no longer reports as failed.

Every open tab of the same wallet sees every wallet-connect request. Two hidden tabs on one laptop both tried to pay the same zap: the ASP refused the second with "payment already in progress", and that error reached Amethyst half a second before the first tab's preimage. A Web Lock per request now lets one tab (or the worker) answer while the rest stay quiet, and a device that does meet "already in progress" waits for the sibling payment's outcome — relaying its preimage only if the payer never speaks — instead of shouting a failure over sats that went through. The losing side also stops writing a failed row into history for it. Co-Authored-By: Claude Fable 5.1 Claude-Session: https://claude.ai/code/session_01QYJfZ4A1TDCEY4Foq3CApR
