• BREAKING: Bump peer dependency @metamask/bridge-controller from ^54.0.0 to ^55.0.0 (#6923)

@metamask/core-backend 3.0.0

Added

• Add forceReconnection() method to BackendWebSocketService for controlled subscription state cleanup (#6861)
  • Performs a controlled disconnect-then-reconnect sequence with exponential backoff
  • Useful for recovering from subscription/unsubscription issues and cleaning up orphaned subscriptions
  • Add BackendWebSocketService:forceReconnection messenger action
• Add stable connection timer to prevent rapid reconnection loops (#6861)
  • Connection must stay stable for 10 seconds before resetting reconnect attempts
  • Prevents issues when server accepts connection then immediately closes it

Changed

• Bump @metamask/base-controller from ^8.4.1 to ^8.4.2 (#6917)
• Update AccountActivityService to use new forceReconnection() method instead of manually calling disconnect/connect (#6861)
• BREAKING: Update allowed actions for AccountActivityService messenger: remove BackendWebSocketService:disconnect, add BackendWebSocketService:forceReconnection (#6861)
• Improve reconnection scheduling in BackendWebSocketService to be idempotent (#6861)
  • Prevents duplicate reconnection timers and inflated attempt counters
  • Scheduler checks if reconnect is already scheduled before creating new timer
• Improve error handling in BackendWebSocketService.connect() (#6861)
  • Always schedule reconnect on connection failure (exponential backoff prevents aggressive retries)
  • Remove redundant schedule calls from error paths
• Update BackendWebSocketService.disconnect() to reset reconnect attempts counter (#6861)
• Update BackendWebSocketService.disconnect() return type from Promise<void> to void (#6861)
• Improve logging throughout BackendWebSocketService for better debugging (#6861)

Fixed

• Fix potential race condition in BackendWebSocketService.connect() that could bypass exponential backoff when reconnect is already scheduled (#6861)
• Fix memory leak from orphaned timers when multiple reconnects are scheduled (#6861)
• Fix issue where reconnect attempts counter could grow unnecessarily with duplicate scheduled reconnects (#6861)
