A reconnected TUI came back as fragments of a frame — Claude Code showed a few rules and its cost line until a resize made it repaint itself. Relay replay is a byte TAIL. It can begin mid-escape and it misses the alt-screen enter, the clears and the absolute positioning that built the frame, so replaying it into the fresh xterm a remount just created paints whatever fragments survive. Main already keeps the thing that does restore a frame: a real @xterm/headless grid, alt-screen aware, fed unconditionally for SSH. Local terminals already repaint from it; SSH was the only path that did not. So this routes an SSH reconnect into the painter that already exists, at the one expression that chooses model over tail. No new call site, no second lifecycle, and every existing gate still applies — a null, renderer-sourced or empty snapshot still degrades to the tail, so it cannot paint blank. ONLY ON THE ALTERNATE SCREEN, and that is the whole design. The reconnect replay reaches the renderer without passing through main's model — forwardReattachReplay and the inline attach replay both bypass onPtyData — so at that moment the model is stale by exactly the outage. For a full-screen app that trade is right: a tail cannot rebuild a frame it no longer contains, a grid can, and the SIGWINCH the restore already sends makes the app redraw the delta. For a scrolling shell it would be wrong: the tail holds output the model never saw, and preferring the grid would drop it for good. A park has no such hole, so it keeps using the model either way. Derived from the PENDING retry, not directSshRetryAttempt. That also matches the live binding, which is written at the same tab generation once a reconnect succeeds and then outlives it — so it stays truthy for every later remount of that generation. Reading it directly is what made my first attempt fire on mounts that were not reconnects. Consumed alongside mountFollowsTerminalPark for the same reason. Verified live against the reported app: Claude Code restores identical to its pre-disconnect frame, top restores coherent and live, and a plain shell still shows output written before the disconnect. 5,470 tests pass across the touched suites. Not the whole story, and the remaining half is already written down: the model's gap exists because the SSH reattach asks for a tail instead of participating in the checkpointed resume the relay already implements. Close that and this paint is not merely coherent but exactly correct, for shells too.
