+# Strict MyPy Typing Standards
+
+This project uses a highly strict MyPy configuration (`strict = true`). When writing or refactoring Python code, you MUST adhere to the following rules to ensure the code passes type checking:
+
+## 1. Absolute Signature Completeness
+- EVERY function and method must have fully typed arguments and a return type (`disallow_untyped_defs`, `disallow_incomplete_defs`).
+- ALWAYS specify `-> None` for functions and methods that do not return a value.
+- NEVER leave type hints partially defined (e.g., typing only some arguments).
+- Decorators must be completely type-hinted using `typing.Callable` or `typing.ParamSpec` (`disallow_untyped_decorators`).
+
+## 2. No Implicit Optionals
+- `arg: str = None` is strictly forbidden.
+- You MUST explicitly union with None: `arg: str | None = None` (`no_implicit_optional`).
+
+## 3. Strict Generics
+- NEVER use bare collections as types.
+- ALWAYS specify the inner types: use `list[str]`, `dict[str, int]`, or `tuple[int, ...]` instead of bare `list`, `dict`, or `tuple` (`disallow_any_generics`).
+
+## 4. Restrictions on `Any` and Subclassing
+- Do not subclass from untyped external libraries or `Any` (`disallow_subclassing_any`).
+- Avoid using external types that have no stubs and resolve to `Any` (`disallow_any_unimported`).
+- Refrain from returning `Any` to avoid contaminating the type inference of calling functions (`warn_return_any`).
+
+## 5. Pydantic Strictness
+- `pydantic.mypy` is active with strict initialization.
+- When instantiating Pydantic models, ensure you are passing exactly the expected typed arguments, as extra or untyped arguments will fail type checks (`init_typed = true`, `init_forbid_extra = true`).
