(not persisted: {err})

Error message

 (not persisted: {err})

What it means

When a reasoning-effort choice is applied from the model picker, the session-level change always takes effect; if the blocking startup-defaults persistence fails, the suffix " (not persisted: {err})" is appended to the status message. This tells the user the selection is active now but will not survive restart — a non-fatal persistence degradation.

Solutions

1. Fix the underlying persist error (permissions, disk, config lock) shown after 'not persisted:'
2. Re-apply the reasoning effort via startup defaults once persistence works
3. Treat the session choice as valid; only restart durability is lost
