Connection reliability
- Signed-in Macs stay reachable. ADE now coordinates rotating account credentials across the desktop app and its background runtime, rejects invalid saved sessions cleanly, and retries directory authorization without leaving a machine in a misleading signed-in-but-offline state.
- A stale presence flag no longer hides a working Mac. If ADE still has a verified secure route, mobile, web, desktop, and ADE Code can try it instead of treating an old cloud “offline” value as final.
- Relay connections become usable before ADE reports success. Readiness, authorization renewal, reconnect fallback, and socket replacement now share one consistent boundary, preventing the brief-connect-then-disconnect behavior seen in the web client.
- One slow request no longer resets everything. Terminal snapshot timeouts and delayed acknowledgements recover their own stream instead of tearing down the entire phone or browser connection.
Chats and state sync
- Chats cannot starve the rest of the app. Chat traffic still gets priority, but machine state is guaranteed regular bandwidth. New shells, sessions, and other changes now continue reaching a phone even on a slow relay connection.
- Slow peers catch up instead of reconnecting forever. ADE re-windows overdue change batches while preserving the socket and cursor, and accepts late acknowledgements safely.
- Large relay messages are handled within Cloudflare’s limits. The relay enforces the real WebSocket frame ceiling and uses hibernation-friendly socket handling without requiring a more expensive Cloudflare plan.
Long-running terminals
- Terminal history no longer freezes at 16 MB. ADE rolls old transcript bytes into a retained tail while keeping logical offsets moving forward, so live output remains resumable instead of becoming permanently blank on mobile.
- Missing output repairs itself. Web and iOS clients detect gaps, deduplicate overlap, and request an authoritative bounded snapshot before resuming live output.
- Rollover is crash-safe. Transaction journals and recovery metadata keep the retained terminal window consistent if ADE exits during transcript maintenance.
iOS and web
- iOS bounds database catch-up work, retries terminal recovery without disconnecting the sync socket, refreshes expired directory authorization, and reports the transport the host actually observed.
- The web client uses a fresh socket for legacy fallback and preserves terminal watermarks through reconnects so a recovered session cannot silently hydrate with zero bytes.
