What changed
Programs backlog recovery is bounded so collecting a delayed window does not hold the rest of the telemetry cycle.
Before
Large or interrupted Programs backlogs could delay collection progress and compete with other telemetry work.
After
Pending Programs windows use bounded work, and confirmed collection progress survives restart and retry.
Compatibility
Existing Programs records remain readable; catch-up coverage still depends on SAP availability and collected history.
What to do
After upgrade, allow pending windows to catch up before assessing coverage.
