No polls yet. Start collecting responses to evaluate SWR behavior.
Browser cache is disabled with Cache-Control: no-store, no-cache, max-age=0, must-revalidate.
CDN cache uses CDN-Cache-Control: public, s-maxage=10, stale-while-revalidate=86400.
s-maxage controls when revalidation starts, while stale-while-revalidate controls how long stale content can still be served.
Polling runs every 2-4s (jittered), using /api/time.json?session=<SESSION_ID>.
The endpoint has an artificial response delay jitter of 2-6s.
Expected behavior: most polls are fast from edge, and payload updates usually land around 12-20s after the previous change.

How to read this
- state: warming up means cache is still being populated.
- state: running means warm-up signals were seen and steady-state checks apply.
- confirmed SWR poll means payload changed and no slow poll happened since the previous payload change.
- slow poll means request duration ≥4.2s.
- suspicious row means this poll matched one or more warning rules (shown in-row).
- MISS is expected during warm-up only; MISS while running should be treated as a cache issue.
Expected policy: no browser cache + public, s-maxage=10, stale-while-revalidate=86400
