- Implement priority queueing in request-queue to prioritize user prompts, question form replies, permissions, commands, and aborts ahead of background sync. - Scale requestQueueLimit to 12 and increase priority request timeout to 180s. - Add retry logic with exponential backoff to question dock mutations. - Increase SQLite busy_timeout to 30s and enable 2GB mmap_size to prevent database lock contention under multi-agent load. - Increase SSE connect timeout to 10s and idle watchdog timeout to 90s to avoid false-positive reconnect storms.
