How freshness is graded

We classify Polymarket as Exchange / order book which means we expect a new observation within 10s under healthy operation. Observations between 10s and 30s are flagged "degraded". Between 30s and 120s we mark "breach" and page an operator. Beyond 120s the source is "stale" and we typically pause comparisons against it until it recovers.
