      # from a bad textual migration) shows up as a parse error right here and stops the run.

      # STEP 2 runs the shipped tests. Import-Module (step 1) is the required gate: it
      # catches the class of bug that broke Windows twice this session (invalid regex compiled
      # by -match, a mangled Save-TcpkJson pipeline from a bad migration). Pester runs as an
      # INFORMATIONAL step until the pre-existing 156-failure population is triaged one file
      # at a time. The results XML is uploaded as an artifact for anyone who wants to look.
      # This is deliberate: a step that reports 156 failures every push and blocks every merge
      # is noise, not signal, and would be turned off. Make it green when the count is down.
