 ## Important Rules
 
+- **NEVER create new Forgejo issues for progress reports.** In Pool
+  Supervisor Mode, create ONE tracking issue at startup and post ALL
+  progress updates as comments on that single issue. Creating separate
+  issues for each progress report pollutes the issue tracker.
 - **NEVER work in /app.** Always use your isolated clone (Worker Mode) or
   Forgejo API only (Pool Supervisor Mode).
 - **NEVER modify code.** You are a tester, not a fixer. File issues only.
