Research direction

Start by reproducing the issue with Invoke-ScriptAnalyzer using the PSUseProcessBlockForPipelineCommand rule and the supplied script definition. Trace how the rule handles pipeline input referenced through $input in an End block; done means the example produces no diagnostic while preserving the rule's behavior for genuinely missing process blocks.

Written by the indexing model from the issue text.

Description

Up-for-Grabs

Repost: Hoping to get some clarification, since this was mechanically closed based on a factually incorrect response to #1912 .

Steps to reproduce

Invoke-ScriptAnalyzer -IncludeRule PSUseProcessBlockForPipelineCommand `
	-ScriptDefinition 'Param([Parameter(ValueFromPipeline=$true)][psobject] $Item); End {$input |ConvertTo-Json}'

Expected behavior
