Connect starts the sign-in; the card that appears is the sign-in rather
than an offer of one; success advances to Review rather than reporting
itself. The two logins end in different places and the button says which:
Claude submits a code back here, so it spins on "Connecting"; OpenAI
finishes in another tab, so it stays a still, disabled Next until the
poll lands.
AdapterLoginPanel grows autoStart / onCancel / onConnected / chrome
rather than a second implementation — the session start, both polls, the
server deadline, the one-shot completion read and the unmount release are
the parts onboarding needs unchanged. Every prop is off by default, so
the agent form and the new-agent page render what they did before.
Claude's code auto-submits on the paste, not on every change:
isValidBrowserCode accepts any printable ASCII from one character up, so
a value-driven submit fired on the first keystroke of anyone who typed.
Also orders the OpenAI card and the settings displayed-code panel
code-above-link, with the instruction worded to match, and releases the
displayed-code session on unmount so an abandoned login stops holding the
one-per-owner reservation.
