Refusing the attach stopped the freeze but told the user to throw the session away (`x` to close, `n` for new), which loses the conversation. tmux's own dead-pane screen already says what to do instead: `claude --resume "<name>"`. The Error card now offers `r` when the row can actually be resumed (claude, with a conversation id and a working directory), and the footer says so. One press resumes into a fresh pane and attaches to it, so a dead end becomes recovery. ⚠️ Three things keep this from becoming the resume runaway that once spawned 35 sessions in 40 seconds. The offer holds a session ID, not a row, and is re-resolved from the model when the key is pressed: a row captured when the card opened is stale by then. It disarms BEFORE anything async, so a second `r` cannot start a second resume. And it routes through resumeSelected(), which owns the `resuming` flag and ends in attachToSession() rather than the group dispatch. ⚠️ The `r` branch has to run BEFORE the generic dismiss, because a message overlay is dismissed by ANY key: without that ordering the offer is consumed as "some key was pressed" and the card merely closes. `help` keeps the any-key behaviour, so the two modes no longer share a case. Verified end to end against a genuinely dead claude pane: card, footer, one press, one new session, and F12 back to the dashboard.
