A reset relay restarts its ids at pty-1, so an id alone can name somebody else's shell: a pane still bound to pty-1 could attach to a shell another pane was already driving, and the two would share keystrokes and output. The guard that used to catch this compared the paneKey and tabId frozen at spawn. It was removed for good reason — a pane moved to another tab was refused its own live shell, and refused as "not found", which read as death and resumed the agent a second time. So it traded a cross-attach for a double resume. The incarnation is the shell's OWN identity, so it discriminates a recycled id without caring where the pane lives: both failures close at once. The relay refuses a mismatch and is deliberately not worded "not found" — that phrasing is what the client maps to an expired session, and expiry authorizes a respawn onto a shell this branch just proved is alive. Only a host-attested expectation is sent. The locally synthesized stand-in is not stable across reconnects and would refuse a pane its own shell. An older relay ignores the field and an older client sends none, so both stay permissive. The tab-keyed comparator is deleted rather than left dormant, and its suite is inverted onto the new identity: a recycled id is still refused, and a pane that moved tabs now attaches instead of being told its shell is gone.
