Summary

• stream Microsoft Entra and Intune device enumeration while buffering only normalized output
• retain a compact Entra correlation cache instead of full Graph SDK objects
• add an additive Get-MyDeviceIntune PropertySet contract with Full as the compatible default and Lifecycle for cleanup consumers
• request only inventory fields used by the Autopilot correlation layer
• keep Graph pagination failures fail-closed without partial output

Compatibility

Existing Get-MyDeviceIntune callers retain the default full Graph query and output shape. Lifecycle is opt-in and is available to CleanupMonster in the published GraphEssentials 0.0.57 release.

Scale evidence

A synthetic 100,000-device Get-MyDevice run retained all 100,000 output/cache records while reducing managed memory by 27.6% and peak working set by 23.5%.

PowerShell 7 and Windows PowerShell 5.1 regression suites pass.
