The direct-copy bypass added earlier was never firing - Get-ChildItem -Filter
uses Win32 filename filtering and does NOT honor PowerShell wildcards or
character classes. The previous detection filter '*[0-9] _*.txt' matched
literal bracket-zero-through-nine text, which never appears in any
filename. $hasBrokenFilenames was therefore always False, and every
218-378-13 series cal apply fell through to the vendor setup.exe which
crashes with System.ArgumentException (exit -532462766).
Confirmed via debug-waxtrace-cal.ps1 log on WJF00159: section 6 reports
the on-disk script has the direct-copy fix, section 7 shows the actual
runtime log line 'running cal Setup.exe' followed by exit -532462766.
The "fix" was never executing because the gate was broken.
Replace -Filter with Get-ChildItem -File + Where-Object regex match on
' _\d+\.txt$' which catches the actual buggy filename pattern (space-
underscore-digits-.txt at end of name) regardless of probe series.
