## Summary
- Treat the sidebar temp-channel icon as a fallback behind working,
mute, numeric unread, and thread-unread indicators.
- Keep the header affordance and the sidebar temp icon when it is the
only row status.
- Extend the ephemeral-channel browser scenario across working, idle,
collapsed-sidebar, and unread states.
## Before / After
| Before: five temp icons compete with duration and unread states |
After: all five duration and unread states remain clear |
