Second review round (spec + standards):
- Polling-off and unreachable render as statusline tokens; the unreachable
span drops mark-strong so the patina dot never sits next to red text.
- Reachability tests assert on the rendered span, which 'reachable' and
'unreachable' substrings never could.
- A pass-log query failure now reads as reachable (no evidence rule) instead
of condemning the browser, and admin.go loses its dead time import.
- startLatestPoller's doc no longer claims the admin page reads the poller;
AGENTS.md carries the RefuseBackoff rename.
