A throw in a later command, or an error with -ErrorAction Stop, reaches a cmdlet through its Write call as an ordinary exception. The catch for the failures of an item reported it as the error of that item and went on, so that Remove-Item2 -PassThru removed the next item after a throw, and the caller never saw the exception. The earlier check found only the end of the pipeline and a break or continue. BaseCmdlet now notes the exception that its WriteObject, WriteVerbose, and WriteDebug raised, and every catch that can enclose a write passes it on; Get-DiskSpace writes outside its try. Set-NTFSSecurityDescriptor and Get-FileHash2 also caught it at a verbose message.
Get-ChildItem2 -Filter *.* returns every item, as Get-ChildItem does. The cmdlet compared each name with the pattern again and dropped the items without a dot, most folders among them; the dot stays an ordinary character in other patterns.
The failed lookup of InheritedFrom frees its native buffer. The help paragraph of -Filter has no pair of asterisks, which platyPS turns into emphasis, and the page has an example for *.*.
Review of the independent pass: the restored-owner test asserts that a plain write is denied, the drive-mapping helper has guard tests and takes letters that the no-volume tests do not, and the pipeline tests cover a throw, an error with -ErrorAction Stop, and the verbose and debug streams for every cmdlet that can reach the code.

A catch for the failures of an item wrapped the write of its object. When a later command ended the pipeline, a break or continue in a script block or Select-Object -First, the exception passed through that catch, which reported it as an error of the item and went on with the next one. Remove-Item2, Copy-Item2, and Move-Item2 with -PassThru then removed, copied, or moved every item although the caller had ended the pipeline, and Set-NTFSOwner and Set-NTFSSecurityDescriptor changed every item. Get-NTFSSecurityDescriptor, Get-NTFSSimpleAccess, and Get-DiskSpace ignored the break, and Get-ChildItem2 ignored it for items below the first folder.
A helper recognizes the end of the pipeline and the control-flow exceptions of PowerShell by their base type, and these catches pass them on. The new table-driven tests run every cmdlet that writes objects: 26 cases for the nine cmdlets fail without the fix in all four configurations and the 64 cases of the others pass.
