A reconnect left every remote terminal blank. Measured on a live relay, not inferred: pty.attach returned no replay for every pane, taking the activation === 'existing' early return in the relay's attach. 'existing' means a source delivery is already open for this client, so it must already be receiving live output and cannot need its screen re-sent. That holds for a duplicate attach. It is false for a reconnect, for a reason neither side can see alone: the client keeps its id across the drop (detachClient refuses to detach the primary, and setWrite revives that same id) so the delivery outlives the dead transport, while the RENDERER has already thrown its terminal away. A reconnect bumps tab.generation, which is the pane's React key, so TerminalPane remounts and the old xterm is disposed with its buffer, and nothing on that path captures it first. Both halves are individually reasonable and together they guarantee a blank pane: the relay reports the client already has the screen, to a client holding a brand-new empty terminal, and nothing paints until new output happens to arrive. Resizing appeared to fix it only because a TUI redraws itself. So the client says which case it is. reattachSshPtySession is by definition painting into a new terminal, so it asks; nobody else does, and the early return keeps working for them. Optional on the wire, so an older relay ignores it and behaves exactly as it does today. Falling through rather than returning the replay inline is deliberate: the path below already drops the pending batched bytes that are also in the buffer, which is what stops the live delivery rendering them twice. Reproduced first as a test against the real dispatcher, source publication and PTY handler (the second attach for one client, which is what a reconnect is) and it fails on the exact symptom before the fix. A second test pins that a caller which does NOT ask still gets nothing, so this cannot become a double-render for the duplicate-attach case the early return exists for. Also updates four provider tests that assert the exact attach params. NOT yet verified in the running app; the log will show replay=true on reconnect.
