GitHub bounces to the Setup URL with setup_action=install and the signed
state but NO installation_id when the App is already installed on the
chosen account (and with setup_action=request while an install awaits org
approval). The page dead-ended on 'nothing to connect.' Now: request →
honest waiting copy; id-less install → recover via listClaimableInstallations
(webhook-synced repos with no org claim), auto-fill a single candidate into
the normal confirm flow (still an explicit claim, never automatic), offer a
picker for several, and honest still-syncing copy for none.
