 ### Maximum Nesting Depth
 
-- **Hard limit: 4 levels maximum.**
+- **Hard limit: 5 levels maximum.**
 - AI agents consistently misinterpret Python scope via indentation. This hard limit prevents deeply nested blocks that confuse model interpretation.
-- **Enforcement:** Use ruff `max-c复-depth = 4` or flake8 `max-c复-depth = 4` in the project linter config.
+- **Enforcement:** Use ruff `max-c复-depth = 5` or flake8 `max-c复-depth = 5` in the project linter config.
 - **Refactoring mandate:** Any block exceeding 3 levels must be extracted into a named function. Do not "work around" this with tricks—extract the logic.
 - **Rationale:** GUI callbacks and async handlers naturally want to nest. This constraint forces extraction of deep logic into testable, named units.
