The counter rode on the first chip, whichever state it happened to be in. It now shows on every chip that is working and on no other: how long a session has been at it is the thing that decides whether to wait for it, where the age of an idle one only says how long ago you stopped looking. The setting keeps its key and changes its name to "Show working time". CLAUDE.md is new, and its first rule is the one broken twice: writing to dconf from a shell attached to the live session bus wipes settings that cannot be recovered.
