Where are the timeframe conditions for sending an SLA breach warning notification defined?

The SLA Definition record defines the schedule, conditions, and duration for the SLA, but it does not contain the notification timeframe conditions - those live in the associated flow.

The Default SLA Flow, built on Flow Designer, contains the logic and trigger stages for SLA notifications including the percentage-of-time-elapsed conditions that determine when warning, breached, and other notification alerts are sent. Editing the flow stages within this flow is where timeframe thresholds for warnings are defined and modified.

SLA Properties is a system properties page that controls global SLA application behavior and settings, not a location for per-notification timeframe conditions.

SLA trigger conditions refer to the conditions that start or stop an SLA timer on a record, not the timeframe thresholds for sending breach warning notifications.
