10200 — discontinuity

Resume could not fill a hole in the realtime history — events between the last cursor and now are missing. Not terminal.

At a glance — no HTTP status · the SDK emits a discontinuity event and jumps the cursor forward.

What to do

• If the UI must be exact, reload message history from REST instead of patching the gap in place.
• Otherwise continue from the new cursor — the stream is live again after the jump.
• Occasional discontinuities after long offline periods are expected; treat frequent ones as a signal, not noise.
