+# Preexisting Issues
+
+Never ignore problems you encounter in the codebase, even if they are outside the current task scope.
+
+## Rules
+
+- When you encounter a bug, lint error, type error, broken test, or code smell while working on a task, do not skip it.
+- If the fix is straightforward (under ~15 minutes of work), fix it in a separate commit with a clear message explaining what was wrong.
+- If the fix is complex (large refactor, architectural change, risk of regression), stop and inform the user: describe the issue, its severity, where it lives, and propose a plan to fix it. Do not attempt complex fixes without approval.
+- Never suppress warnings, disable lint rules, or add `// @ts-ignore` to hide preexisting issues. Surface them.
+- When fixing a preexisting issue, add a test that would have caught it if one does not already exist.
+- Track issues you cannot fix immediately: flag them to the user and, if Memora is available, create an issue memory.
