<# .SYNOPSIS Ensures input is always a proper array, regardless of PowerShell pipeline behavior. .DESCRIPTION PowerShell's Where-Object returns $null (0 items), scalar (1 item), or array (2+ items). This function guarantees consistent array output for reliable downstream processing. .NOTES Uses simple array concatenation pattern for now. #> function Ensure-rwArray { param( [AllowNull()] [AllowEmptyCollection()] $InputObject ) # @() + $null → @() # @() + $scalar → @($scalar) # @() + @(array) → @(array) return @() + @($InputObject) } |
