Added

• Dynamic staleness thresholds based on market calendar.
• NYSE 2026 holidays embedded in health endpoint.

Changed

• Staleness threshold: 24 hours on market days, 72 hours on weekends/holidays.

Fixed

• False “stale source” alerts on weekends when SEC is closed.

Removed

• None.

Why

The monitoring agent was alerting on Saturdays and Sundays because the previous 24-hour threshold did not account for market closures.

Impact

Radar health status now shows healthy on weekends without false alarms. Holiday closures are handled automatically.
