You are a principal Python software engineer resolving a repository issue in `/workspace`.
Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run.

## Critical Environment & Grader Rules
1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`.
2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files.
3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`.
4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks:
   `pytest path/to/test_file.py -k pattern -q --tb=short --no-header`
   If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off.
5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission.

## Execution Protocol

### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls)
- The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories.
- Run a single compound `run_command` with `grep -rn --include="*.py"` to locate:
  (a) the exact symbols, error strings, or functions from the problem description,
  (b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and
  (c) the closest existing unit test files under `tests/`.

### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls)
- Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests.
- Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types.

### Phase 3 — Reproduce Bug in One Call (1 tool call)
- Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts.

### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls)
- Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`.
- Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests.
- **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`.

### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls)
- Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`.
- Run `git status --short && git diff` via `run_command`. Confirm:
  - ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately),
  - ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched),
  - Minimal, clean diff with valid imports and indentation.
- Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.

When trying to use the `validate_arguments` decorator, I face the issue of getting validation errors for an extra attribute for a TypedDict as below:

```py
from typing_extensions import TypedDict

from pydantic import validate_arguments, Extra


class TypedTest(TypedDict):
    y: str


@validate_arguments(config={'extra': Extra.allow})
def test(other: TypedTest):
    pass


test(other={'y': 'b', 'z': 'a'})

```

Output:
```
pydantic.error_wrappers.ValidationError: 1 validation error for Test
other -> z
  extra fields not permitted (type=value_error.extra)
```

Expected: No errors

Anything I have missed that would let this validation pass for extra attributes in the TypedDict?

Thanks very much!

## Task Budget (Session terminates when any budget is exhausted)
- Time allowance: 7.5 minutes
- Tool calls allowance: 30 calls
- Max loop iterations: 40 turns

## Execution Environment Rules
- Single command timeout: 90 seconds (commands exceeding this fail without ending the session)
- Command output limit: 5000 characters
- File view limit: 150 lines per read_file call
- File character limit: 10000 characters per read_file call
- Environment is offline (no network/PyPI access). All repository and test dependencies are ALREADY pre-installed. Do NOT attempt to run pip install or download packages.

## Instructions:
0. All source code is under `/workspace`. Do NOT search outside `/workspace` (e.g. `/usr/`, `/wheels/`, system site-packages). If imports fail, the issue is in the source code under `/workspace`, not in missing system packages.
1. Analyze the problem statement and any provided hints carefully to identify all requested script paths, CLI subcommands, or Python modules.
2. Inspect existing codebase conventions and test files before making edits.
3. Verify your implementation using targeted tests or inline assertions before submitting.
4. Call submit_patch only after your implementation is complete and verified.
5. As your final action, you must return a text-only response reporting your completion to terminate the session.

The user is reporting a bug where the `extra` config in `validate_arguments` is not respected when the argument type is a `TypedDict`.

Example provided:
```python
from typing_extensions import TypedDict
from pydantic import validate_arguments, Extra

class TypedTest(TypedDict):
    y: str

@validate_arguments(config={'extra': Extra.allow})
def test(other: TypedTest):
    pass

test(other={'y': 'b', 'z': 'a'})
```
Expected: No errors.
Actual: `pydantic.error_wrappers.ValidationError: 1 validation error for Test\nother -> z\n  extra fields not permitted (type=value_error.extra)`

This looks like `validate_arguments` creating a model (or something similar) to validate the arguments, and the configuration for `extra` is not being passed down correctly when validating a `TypedDict`.

Let's start by reproducing the bug.

The reproduction script confirms the bug. The `extra` config is ignored and it defaults to (presumably) `Extra.forbid` or `Extra.ignore` is not working as expected, actually it says "extra fields not permitted", which means it thinks it's `Extra.forbid`.

Wait, let's check what the default `extra` is. Usually it's `Extra.ignore`.

If I change `Extra.allow` to `Extra.forbid`, it should still fail.
If I don't provide `extra` config, what happens?

Let's investigate how `validate_arguments` is implemented. It's likely in `pydantic/decorator.py`.

I need to see the rest of `pydantic/decorator.py`, especially the `create_model` method. <channel|><|tool_call>call:read_file{filepath:<|"|>pydantic/decorator.py<|"|>,start_line:151}<tool_call|><|tool_response>

In `create_model`, I see:

```python
        class DecoratorBaseModel(BaseModel):
            # ... validators ...

            class Config(CustomConfig):
                extra = Extra.forbid
```

Wait, the `DecoratorBaseModel` has a nested `Config` class that sets `extra = Extra.forbid`.
`CustomConfig` is created from the `config` argument passed to `validate_arguments`.

If `config={'extra': Extra.allow}` is passed, `CustomConfig` will have `extra = Extra.allow`.
But `class Config(CustomConfig): extra = Extra.forbid` will override it to `Extra.forbid`.

Wait, let's check:
If `config` is `{'extra': Extra.allow}`, then `CustomConfig` is a class with `extra = Extra.allow`.
Then `class Config(CustomConfig): extra = Extra.forbid` will indeed set `extra` to `Extra.forbid`.

This explains why `extra` fields are not permitted for the function arguments in general.
But the user is talking about `TypedDict` inside the function arguments.

Wait, if `DecoratorBaseModel` has `extra = Extra.forbid`, it means any argument not defined in the function signature will be rejected.
In the user example:
```python
@validate_arguments(config={'extra': Extra.allow})
def test(other: TypedTest):
    pass

test(other={'y': 'b', 'z': 'a'})
```
Here, `other` is a defined argument. The value passed to `other` is `{'y': 'b', 'z': 'a'}`.
The validation for `other` should use the type `TypedTest`.
`TypedTest` is a `TypedDict`.

Pydantic's handling of `TypedDict` usually involves creating a model or using a specific validator.

If `other` is validated as a `TypedDict`, does it use the model's config?
Typically, when Pydantic validates a `TypedDict`, it might create a temporary model or use some internal logic.

Let's look at how `TypedDict` is handled in pydantic.
I'll search for `TypedDict` in the codebase.

In `make_typeddict_validator`:

```python
def make_typeddict_validator(
    typeddict_cls: Type['TypedDict'], config: Type['BaseConfig']  # type: ignore[valid-type]
) -> Callable[[Any], Dict[str, Any]]:
    from .annotated_types import create_model_from_typeddict

    TypedDictModel = create_model_from_typeddict(
        typeddict_cls,
        __config__=config,
        __module__=typeddict_cls.__module__,
    )
    typeddict_cls.__pydantic_model__ = TypedDictModel  # type: ignore[attr-defined]

    def typeddict_validator(values: 'TypedDict') -> Dict[str, Any]:  # type: ignore[valid-type]
        return TypedDictModel.parse_obj(values).dict(exclude_unset=True)

    return typeddict_validator
```

It passes the `config` to `create_model_from_typeddict`, which then passes it to `create_model` as `__config__`.

Now let's see how `validate_arguments` uses this.
`validate_arguments` creates a `DecoratorBaseModel` and then calls `create_model`.

```python
        class DecoratorBaseModel(BaseModel):
            # ...
            class Config(CustomConfig):
                extra = Extra.forbid

        self.model = create_model(to_camel(self.raw_function.__name__), __base__=DecoratorBaseModel, **fields)
```

The `DecoratorBaseModel`'s `Config` is set to `Extra.forbid`.
When `create_model` is called, `self.model` (the model for the function arguments) will have `Extra.forbid`.

When `self.model` is instantiated (which happens in `init_model_instance` via `self.model(**values)`), Pydantic validates the fields. One of those fields is `other` which has type `TypedTest` (a `TypedDict`).

Pydantic's internal validation logic for `TypedDict` will use `make_typeddict_validator`.
Wait, where is `make_typeddict_validator` called?

I'll search for who calls `make_typeddict_validator` (or rather, where it's used).
It's not called directly in `pydantic/main.py` or `pydantic/validators.py`'s `_VALIDATORS` list?
Actually, `_VALIDATORS` is a list of `(Type, [validators])`. `TypedDict` is not in that list.

Pydantic probably handles `TypedDict` specially during model field creation.

Let's look at `pydantic/main.py` to see how models are created and how they handle `TypedDict`.

It's inside some generator function (likely `get_validators`).

```python
    if is_typeddict(type_):
        yield make_typeddict_validator(type_, config)
        return
```

The `config` passed to `make_typeddict_validator` is the current model's config.
In the case of `@validate_arguments`, the current model is `self.model`, which is a `DecoratorBaseModel`.
And `DecoratorBaseModel` has `Config.extra = Extra.forbid`.

If the user provides `@validate_arguments(config={'extra': Extra.allow})`, the `DecoratorBaseModel` is created with that config!

Wait, let's look at `pydantic/decorator.py` again.

```python
        class DecoratorBaseModel(BaseModel):
            # ...
            class Config(CustomConfig):
                extra = Extra.forbid
```

If `CustomConfig` is `BaseModel.Config` updated with user config, then `DecoratorBaseModel.Config`'s `extra = Extra.forbid` will OVERRIDE the user's `extra` if `CustomConfig` is just used as a base class.

Wait, `class Config(CustomConfig): extra = Extra.forbid` means `extra` is ALWAYS `Extra.forbid` for `DecoratorBaseModel`, regardless of what `CustomConfig` has.

It's inside some generator function (likely `get_validators`). ```python if is_typeddict(type_): yield make_typeddict_validator(type_, config) return ``` The `config` passed to `make_typeddict_validator` is the current model's config. In the case of `@validate_arguments`, the current model is `self.model`, which is a `DecoratorBaseModel`. And `DecoratorBaseModel` has `Config.extra = Extra.forbid`. If the user provides `@validate_arguments(config={'extra': Extra.allow})`, the `DecoratorBaseModel` is created with that config! Wait, let's look at `pydantic/decorator.py` again. ```python class DecoratorBaseModel(BaseModel): # ... class Config(CustomConfig): extra = Extra.forbid ``` If `CustomConfig` is `BaseModel.Config` updated with user config, then `DecoratorBaseModel.Config`'s `extra = Extra.forbid` will OVERRIDE the user's `extra` if `CustomConfig` is just used as a base class. Wait, `class Config(CustomConfig): extra = Extra.forbid` means `extra` is ALWAYS `Extra.forbid` for `DecoratorBaseModel`, regardless of what `CustomConfig` has. Let's re-read `pydantic/decorator.py`. <channel|><|tool_call>call:read_file{filepath:<|"|>pydantic/decorator.py<|"|>}<tool_call|><|tool_response>

Found it:

```python
            class Config(CustomConfig):
                extra = Extra.forbid
```

This is exactly what I suspected. Even if `CustomConfig` (which comes from the user's `config` parameter) has `extra = Extra.allow`, it is overwritten here.

Wait, but `@validate_arguments` is for validating the function arguments. The `DecoratorBaseModel` (and its child `self.model`) should indeed forbid extra arguments to the function call. If you call `foo(a=1)` and it only takes `b`, it should be an error.

But the bug report says:
"When `@validate_arguments(config={'extra': Extra.allow})` is used, providing extra fields to a `TypedDict` argument still results in a `ValidationError` stating 'extra fields not permitted.'"

Ah! The `TypedDict` argument is a FIELD of `self.model`.
When `self.model` is instantiated, Pydantic validates its fields.
If one field is a `TypedDict`, Pydantic creates a model for that `TypedDict` (via `make_typeddict_validator`).

`make_typeddict_validator` is called with `config`, which is the config of the model being validated (i.e., `self.model`).
Since `self.model`'s `config.extra` is `Extra.forbid` (because of `DecoratorBaseModel.Config.extra = Extra.forbid`), the `TypedDict` model also gets `extra = Extra.forbid`.

So, the `extra = Extra.forbid` in `DecoratorBaseModel` is too aggressive. It affects not only the function arguments (the fields of `self.model`) but also any `TypedDict` arguments (the fields of the `TypedDict` model).

Wait, but if `extra = Extra.allow` is passed to `@validate_arguments`, it SHOULD allow extra arguments to the function.

If the user wants to allow extra arguments to the function, `self.model` should have `extra = Extra.allow`.

But if the user DOES NOT provide `config={'extra': ...}`, the default behavior of `@validate_arguments` seems to be forbidding extra arguments.

Let's look at `DecoratorBaseModel`'s `Config` again.

```python
            class Config(CustomConfig):
                extra = Extra.forbid
```

This means it ALWAYS forbids extra arguments, even if `CustomConfig` allows them. This looks like a bug in general for `@validate_arguments` if you wanted to allow extra arguments to the function itself.

But the specific issue is about `TypedDict` arguments.

If `CustomConfig` has `extra = Extra.allow`, and `DecoratorBaseModel.Config` has `extra = Extra.forbid`, then `self.model` (which inherits from `DecoratorBaseModel`) will have `extra = Extra.forbid`.

When `make_typeddict_validator(type_, config)` is called, `config` is `self.model.__config__` (which has `extra = Extra.forbid`).

If we want to respect the user's `extra` config for both the function arguments AND the `TypedDict` arguments, we should not hardcode `extra = Extra.forbid` if the user provided a different value.

However, we probably still want `extra = Extra.forbid` by default for `@validate_arguments` if no config was provided.

Wait, if I change:
```python
            class Config(CustomConfig):
                extra = Extra.forbid
```
to something that respects `CustomConfig.extra`?

Actually, if `CustomConfig` is `BaseConfig` by default, `BaseConfig.extra` is `Extra.ignore` (usually).

Let's check `pydantic/config.py`.

If the user wants to allow extra arguments to the function, `self.model` should have `extra = Extra.allow`. But if the user DOES NOT provide `config={'extra': ...}`, the default behavior of `@validate_arguments` seems to be forbidding extra arguments. Let's look at `DecoratorBaseModel`'s `Config` again. ```python class Config(CustomConfig): extra = Extra.forbid ``` This means it ALWAYS forbids extra arguments, even if `CustomConfig` allows them. This looks like a bug in general for `@validate_arguments` if you wanted to allow extra arguments to the function itself. But the specific issue is about `TypedDict` arguments. If `CustomConfig` has `extra = Extra.allow`, and `DecoratorBaseModel.Config` has `extra = Extra.forbid`, then `self.model` (which inherits from `DecoratorBaseModel`) will have `extra = Extra.forbid`. When `make_typeddict_validator(type_, config)` is called, `config` is `self.model.__config__` (which has `extra = Extra.forbid`). If we want to respect the user's `extra` config for both the function arguments AND the `TypedDict` arguments, we should not hardcode `extra = Extra.forbid` if the user provided a different value. However, we probably still want `extra = Extra.forbid` by default for `@validate_arguments` if no config was provided. Wait, if I change: ```python class Config(CustomConfig): extra = Extra.forbid ``` to something that respects `CustomConfig.extra`? Actually, if `CustomConfig` is `BaseConfig` by default, `BaseConfig.extra` is `Extra.ignore` (usually). Let's check `pydantic/config.py`. <channel|><|tool_call>call:read_file{filepath:<|"|>pydantic/config.py<|"|>}<tool_call|><|tool_response>
