What it means

Error "Failed to capture workflow source from ${sourceRoot}: ${(error as Error).message}" thrown in coleam00/Archon.

  // THAT checkout's `.archon`, not the parent checkout's bytes captured on entry — the
  // branch may carry a different workflow YAML, and executing one against the other is
  // exactly the mixed-vintage defect (#2660/#2747). Re-freeze the source and re-discover
  // from the lane path once the lane resolves it.
