 ## Decision points
 
+- **Tempted to look at a page yourself** although the harness has subagents - because the report
+  seems thin, or to check a label before writing it down? Do not. Send the subagent back with the
+  specific question, or write the statement as uncertain (step 4). Reading in this session is
+  for a harness without subagents only; doing it anyway is exactly what fills this context.
 - **The user chose "none"?** Step 5 only. The pages stay listed with that reason, so the next
   pass does not renegotiate them.
 - **Hundreds of selected pages (a handbook)?** The threshold applies as it is: stop at step 2
