Supabase application-state RPCs have a 12-second UI timeout; sync cannot remain stuck forever in “Синхронизация…”.\n3. SUN_CONFLICT retries use exponential backoff and stop after four safe retries.\n4. Stability logging reports the real app version, deduplicates repeated identical errors for five minutes, prevents concurrent mirror/backup/error flush runs and backs off on network failures.\n5. Developer-admin checks are cached/throttled and protected by an 8-second timeout.\n6. Read-only support live refresh updates the company snapshot in place instead of clearing and re-entering the workspace every cycle.\n7. Operations boot polling is bounded, background maintenance is slower/cleanable, and image mutation scanning is batched.\n8.
