 - **Dependency Injection:** Module-level functions that require class state should accept the instance as their first argument (e.g., `def my_extracted_logic(controller: AppController, ...)`).
 - **Handler Maps:** Replace massive `if/elif` blocks (like those in event dispatchers) with dictionaries mapping keys to module-level handler functions.
 - **Inner Class Extraction:** Never define nested classes or functions within methods. Move them to the module level.

+## 16. See Also — Per-File Pattern Demonstrations
+
+The following per-source-file guides show these conventions applied in real code:
+
+- **[docs/guide_gui_2.md](../../../docs/guide_gui_2.md):** §"UI Delegation Pattern" — 90+ module-level `render_xxx(app)` functions in `src/gui_2.py`. Every panel uses the `App` instance as injected state, never `self`.
+- **[docs/guide_app_controller.md](../../../docs/guide_app_controller.md):** §"Hook API Surface" — `_predefined_callbacks` and `_gettable_fields` as handler maps, not if/elif chains. §"AppState" — dataclass with all-typed fields, no methods.
+- **[docs/guide_command_palette.md](../../../docs/guide_command_palette.md):** §"CommandRegistry" — decorator-based registration (`@registry.register`) instead of list-of-dicts. §"defensive try/except wrapping" — handler-map style error isolation.
+- **[docs/guide_mcp_client.md](../../../docs/guide_mcp_client.md):** §"3-Layer Security Model" — handler-map dispatch (`def dispatch(tool_name, ...)`) with one branch per tool, instead of polymorphism.
+- **[docs/guide_multi_agent_conductor.md](../../../docs/guide_multi_agent_conductor.md):** §"WorkerPool" — module-level `run_mma_worker` function, not a class method. The `WorkerPool` is justified (encapsulates semaphore + executor + active set).
+- **[docs/guide_models.md](../../../docs/guide_models.md):** §"Data Structures" — `dataclass(frozen=True)` and `pydantic` over OOP classes for data-only containers.
