The scraper folded traefik_service_requests_total{code} into two shares and
dropped the code, so a problem couldn't say whether it was scanners (404), a
login wall (401/403) or the app down (502/503/504). Each scrape now stores the
responses per router and code that occurred (traefik_status_codes, migration
traefik_006), pruned with the router metrics and left out of backups (System
180 ruling: Traefik history is not backed up). A problem card lists its codes
over the last 15 minutes, most first, or says none occurred, or that codes
aren't recorded yet.
A counter series new since the previous scrape now counts from 0 instead of
being skipped: Traefik creates a router's 502 series at its first 502, so a
first burst of 5xx read as 0% until it happened again.

The Traefik page now reads state first: a verdict naming each router that
needs a look, why, and when it started (from its history buckets over the
page's range), then the request chart following the page's time range, then
the problem cards (which say since when too), the proxy's own figures, and
the healthy rest. The verdict is filled out of band by /rows each poll; the
"Needs attention" and "Healthy routers" tiles it replaces are gone.
The request chart takes ?range= from the page; past a day its times carry the
day, and its clock is 24-hour (hourCycle h23).
