"Watch the cleanup side of retention" applies one level up too. On Azure the managed disks that back PVCs have a `diskState` worth reading before trusting a count: `Unattached` is the real orphan; `Reserved` means the disk belongs to a stopped-deallocated VM and comes back on Start; `ActiveSAS` means someone ran `az disk grant-access` and is exporting the VHD. The portal-style check "managedBy is null" lists the last two as free to delete; `az disk list --query "[?diskState=='Unattached'].[name,diskSizeGb,lastOwnershipUpdateTime]" -o table` does not. Same pattern as your snapshots: the object that "works" for days is the one whose delete path nobody exercised, so the inventory is the test.
