Progress (2026-10-23):

Lingering is on for jacob: loginctl show-user jacob shows Linger=yes.
Token saved: the token is made, but no release can save it yet. Setup's question comes from A credentials section for Claude's setup token #1010, which merged into Spec: Experiments, which measure a change before it reaches production #977's Spec branch (draft PR Spec: Experiments, which measure a change before it reaches production #1122), not main. 0.14.3 refuses unknown Credentials sections, so the token can't be added by hand either. Once a release with Spec: Experiments, which measure a change before it reaches production #977 is installed on the thirdshift host, run thirdshift setup again to save it.

Done (2026-10-23):

Lingering is on for jacob: loginctl show-user jacob shows Linger=yes.
The token is saved in the credentials file, through thirdshift setup on 0.14.5, which carries Save Claude setup tokens in Credentials #1125 by way of Save Claude setup tokens in Credentials on main #1170.
