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.

You are evaluating a software engineering task for repository callowayproject/bump-my-version.

Problem Statement:
Zero-padded version parts are not working
              It seems that this fix was removed with some refactoring happened in #112. Tried with version 0.20.1 and the following config parameters:
```
current_version = "5.06.0"
parse = "(?P<major>\\d+)\\.(?P<minor>\\d+)\\.(?P<patch>\\d+)"
serialize = ["{major}.{minor:02}.{patch}"]
search = "{current_version}"
replace = "{new_version}"
```
Increasing minor would result in version 5.70.0 which is obviously wrong. Any chances we get this functionality back? Or is there any other possibility to have fixed length version numbers?

## 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 zero-padded version parts are not working.
Specifically, with `serialize = ["{major}.{minor:02}.{patch}"]` and `current_version = "5.06.0"`, increasing the minor version results in `5.70.0` instead of `5.07.0` (or similar).
Wait, the issue says "Increasing minor would result in version 5.70.0 which is obviously wrong."
If `current_version` is `5.06.0` and we increment `minor`, it should become `5.07.0`.
If the output is `5.70.0`, it suggests that maybe the `06` is being interpreted as octal or something, or the formatting is weird.
Actually, if `minor` is `6`, then `{minor:02}` should be `06`.
If the increment happens: `6` becomes `7`. Then `{minor:02}` should be `07`.
Wait, "Increasing minor would result in version 5.70.0". Let me re-read.
If `current_version` is `5.06.0` and we increase `minor`, it should be `5.07.0`.
Why does the user say `5.70.0`?
Wait, maybe they meant `5.7.0`? No, they said `5.70.0`.
Wait, if the minor version is `06`, and it's treated as a string or handled incorrectly, and then incremented...
Actually, if the minor version is `6`, and it's formatted as `{minor:02}`, it should be `06`.
If it's incremented to `7`, it should be `07`.
If the result is `5.70.0`, that's very strange.
Maybe they meant `5.6.0` -> `5.7.0` and they wanted `5.06.0` -> `5.07.0` but they got something else?
Actually, read carefully: `current_version = "5.06.0"`. `serialize = ["{major}.{minor:02}.{patch}"]`.
If we increase minor, it should go from `6` to `7`. The serialized version should be `5.07.0`.
If they get `5.70.0`, maybe it's because they are using some other logic.

Let's investigate how the version is parsed and serialized.
The relevant files seem to be:
- `bumpversion/version_part.py`
- `bumpversion/versioning/serialization.py`
- `bumpversion/versioning/models.py`
- `bumpversion/versioning/functions.py`

I'll start by searching for "serialize" and formatting logic in the codebase.

Wait, look at `VersionComponent.__format__`:

```python
    def __format__(self, format_spec: str) -> str:
        try:
            val = int(self.value)
        except ValueError:
            return self.value
        else:
            return int.__format__(val, format_spec)
```

This seems to correctly handle formatting if `self.value` can be converted to an integer.
If `self.value` is `"06"`, `int("06")` is `6`. Then `int.__format__(6, "02")` should be `"06"`.

The issue is that "Increasing minor would result in version 5.70.0".
Wait, if `current_version` is `5.06.0` and it's bumped to `5.07.0`.
The formatted version should be `5.07.0`.
Why would they get `5.70.0`?

Let's try to reproduce this.
I need a reproduction script. I'll use the configuration provided in the issue.
`current_version = "5.06.0"`
`parse = "(?P<major>\\d+)\\.(?P<minor>\\d+)\\.(?P<patch>\\d+)"`
`serialize = ["{major}.{minor:02}.{patch}"]`
`search = "{current_version}"`
`replace = "{new_version}"`

I will write a script to simulate the bump and serialization process.

Wait, look at `Version.values()`:

```python
    def values(self) -> Dict[str, str]:
        \"\"\"Return the values of the parts.\"\"\"
        return {key: value.value for key, value in self.components.items()}
```

It returns `value.value`. And `VersionComponent.value` is:

```python
    @property
    def value(self) -> str:
        \"\"\"Return the value of the part.\"\"\"
        return self._value or self.func.optional_value
```

This is a `str`.
Now look back at `serialize` in `bumpversion/versioning/serialization.py`:

```python
    local_context = copy(context)
    local_context.update(version.values())
    # ...
    serialized = chosen_pattern.format(**local_context)
```

`local_context` now contains strings for the version parts.
When `chosen_pattern.format(**local_context)` is called, it's using strings in the format arguments.
Strings in Python's `.format()` do NOT support format specifiers like `:02`.
`:02` only works for numbers (integers, floats).

If `local_context['minor']` is `"06"`, and the pattern is `{minor:02}`, Python's `.format()` will raise a `ValueError` or just not work as expected if it's a string.
Actually, if you do `"{:02}".format("06")`, it works and produces `"06"`. But if you do `"{:02}".format("6")`, it produces `"60"`.
Wait, let's check that.
`"{:02}".format("6")` -> `'6 '` or something? No.
Let's check:
`"{:2}".format("6")` -> `' 6'` (right aligned, width 2)
`"{:02}".format("6")` -> `ValueError: Unknown format code '0' for object of type 'str'`

Ah! So if `local_context` has strings, `chosen_pattern.format(**local_context)` will FAIL if `:02` is used!
But the user says "Increasing minor would result in version 5.70.0".
Wait, if it doesn't raise a `ValueError`, what happens?
Actually, `"{:02}".format("6")` DOES raise `ValueError`.

Wait, maybe `localize_context` was intended to have `VersionComponent` objects, not their string values?
If `local_context` contained `VersionComponent` objects, then `VersionComponent.__format__` would be called.
And `VersionComponent.__format__` is defined as:

```python
    def __format__(self, format_spec: str) -> str:
        try:
            val = int(self.value)
        except ValueError:
            return self.value
        else:
            return int.__format__(val, format_spec)
```

This IS what we want!

So the bug is in `serialize` in `bumpversion/versioning/serialization.py` where it uses `version.values()` instead of the components themselves.
Wait, let's check `Version.values()` again.
```python
    def values(self) -> Dict[str, str]:
        \"\"\"Return the values of the parts.\"\"\"
        return {key: value.value for key, value in self.components.items()}
```
It returns the string values.

If `serialize` did:
```python
    local_context.update(version.components) # Use the VersionComponent objects
```
Then `chosen_pattern.format(**local_context)` would call `VersionComponent.__format__`.

Let's verify this with a reproduction script.

Wait, I am confused. I'll try this in a local shell if I could. But I can't.
Wait, I just ran it and it returned `70`.
Wait, `"{:02}".format("7")`.
For a string, `0` is not a valid padding character?
Wait, let me check the Python docs for string formatting.
For strings:
`'N'` for narrow, `'W'` for wide.
`'<'`, `'>'`, `'^'` for alignment.
`'.precision'` for max length.
`'width'` for minimum width.

So `"{:02}".format("7")`
`0` is not a valid alignment.
Wait, `0` is the padding character if the type is `d` (decimal).
But for strings, the default is space.
Wait, maybe `0` is being interpreted as something else?

No, I'm not hallucinating. `"{:02}".format("7")` is indeed `'70'`.
Wait, why?
Looking at the Python documentation for the `format()` function and the `format` mini-language.
If the value is a string, the format specifier `02` means:
- `0`: This is NOT a valid alignment for strings.
- `2`: Width is 2.

Wait, I just remembered something. In some contexts, if you provide a format spec that is not valid for the type, Python might behave strangely or raise an error.
But why `70`?
Is `0` being treated as a digit?
Actually, let me try `"{:0-2}".format("7")`

Okay, so for integer it's `07`. For string it's `70`.
Wait, this is so weird. I've never seen this in Python.
Let me check `"{:02}".format("7")` in a real Python 3.10 environment.
Wait! I just realized. I might be running it in an environment where `format` is overwritten? No, that's unlikely.

Wait... is it possible that `02` for a string is interpreted as "width 2" and the `0` is just... I don't know.
Anyway, the point is that `local_context` contains strings, and when `.format()` is called on those strings, the result is NOT what we want.
If `local_context` contained the `VersionComponent` objects, it would call `VersionComponent.__format__`, which converts the value to an integer and then calls `int.__format__`.

So the fix is to pass the `VersionComponent` objects in `local_context` instead of their string values.

Let's verify this.

YES! That's it. `5.07.0`.
So the fix is to change `local_context.update(version.values())` to `local_context.update(version.components)` in `bumpversion/versioning/serialization.py`.

Wait, let's check if `version.components` is what I think it is.
In `Version.__init__`:
```python
class Version:
    def __init__(
        self, version_spec: VersionSpec, components: Dict[str, VersionComponent], original: Optional[str] = None
    ):
        self.version_spec = version_spec
        self.components = components
```
Yes, `self.components` is a `Dict[str, VersionComponent]`.

So the change is:
In `bumpversion/versioning/serialization.py`:
Change:
```python
    local_context = copy(context)
    local_context.update(version.values())
```
To:
```python
    local_context = copy(context)
    local_context.update(version.components)
```

Wait, what about other parts of the code? Does `version.values()` get used elsewhere in a way that we might break?
`Version.values()` is used in `serialize` (the function we're fixing) and that's about it in `serialization.py`.
Let's check where else `Version.values()` is called.

Ok, it's only used in `serialize`. So this change is safe and targeted.

Wait, I should check if `VersionComponent` objects are compatible with the rest of the code in `serialize`.
The `local_context` is passed to `chosen_pattern.format(**local_context)`.
If `local_context` values are `VersionComponent` objects, `.format()` will call `__format__` on them, which is exactly what we want.
If they were strings, `.format()` would just use the string.
So this is correct.

All steps completed.
1. Identified root cause: `serialize` was using `version.values()` (strings) instead of `version.components` (`VersionComponent` objects), bypassing the custom `__format__` logic for zero-padding.
2. Reproduced the bug with a script.
3. Applied the fix by changing `version.values()` to `version.components` in `bumpversion/versioning/serialization.py`.
4. Verified the fix with the reproduction script and existing tests.
5. Confirmed the diff is minimal and correct.
Turn 28at 447 s
The issue was that zero-padded version parts (e.g., `{minor:02}`) were not rendering correctly because the `serialize` function passed raw string values from `version.values()` to `.format()`, bypassing the `VersionComponent.__format__` method. I updated `bumpversion/versioning/serialization.py` to use `version.components` instead, ensuring that `VersionComponent` objects are used during formatting.

The user is reporting a bug where zero-padded version parts are not working.
Specifically, with `serialize = ["{major}.{minor:02}.{patch}"]` and `current_version = "5.06.0"`, increasing the minor version results in `5.70.0` instead of `5.07.0` (or similar).
Wait, the issue says "Increasing minor would result in version 5.70.0 which is obviously wrong."
If `current_version` is `5.06.0` and we increment `minor`, it should become `5.07.0`.
If the output is `5.70.0`, it suggests that maybe the `06` is being interpreted as octal or something, or the formatting is weird.
Actually, if `minor` is `6`, then `{minor:02}` should be `06`.
If the increment happens: `6` becomes `7`. Then `{minor:02}` should be `07`.
Wait, "Increasing minor would result in version 5.70.0". Let me re-read.
If `current_version` is `5.06.0` and we increase `minor`, it should be `5.07.0`.
Why does the user say `5.70.0`?
Wait, maybe they meant `5.7.0`? No, they said `5.70.0`.
Wait, if the minor version is `06`, and it's treated as a string or handled incorrectly, and then incremented...
Actually, if the minor version is `6`, and it's formatted as `{minor:02}`, it should be `06`.
If it's incremented to `7`, it should be `07`.
If the result is `5.70.0`, that's very strange.
Maybe they meant `5.6.0` -> `5.7.0` and they wanted `5.06.0` -> `5.07.0` but they got something else?
Actually, read carefully: `current_version = "5.06.0"`. `serialize = ["{major}.{minor:02}.{patch}"]`.
If we increase minor, it should go from `6` to `7`. The serialized version should be `5.07.0`.
If they get `5.70.0`, maybe it's because they are using some other logic.

Let's investigate how the version is parsed and serialized.
The relevant files seem to be:
- `bumpversion/version_part.py`
- `bumpversion/versioning/serialization.py`
- `bumpversion/versioning/models.py`
- `bumpversion/versioning/functions.py`

I'll start by searching for "serialize" and formatting logic in the codebase.

Specifically, with `serialize = ["{major}.{minor:02}.{patch}"]` and `current_version = "5.06.0"`, increasing the minor version results in `5.70.0` instead of `5.07.0` (or similar). Wait, the issue says "Increasing minor would result in version 5.70.0 which is obviously wrong." If `current_version` is `5.06.0` and we increment `minor`, it should become `5.07.0`. If the output is `5.70.0`, it suggests that maybe the `06` is being interpreted as octal or something, or the formatting is weird. Actually, if `minor` is `6`, then `{minor:02}` should be `06`. If the increment happens: `6` becomes `7`. Then `{minor:02}` should be `07`. Wait, "Increasing minor would result in version 5.70.0". Let me re-read. If `current_version` is `5.06.0` and we increase `minor`, it should be `5.07.0`. Why does the user say `5.70.0`? Wait, maybe they meant `5.7.0`? No, they said `5.70.0`. Wait, if the minor version is `06`, and it's treated as a string or handled incorrectly, and then incremented... Actually, if the minor version is `6`, and it's formatted as `{minor:02}`, it should be `06`. If it's incremented to `7`, it should be `07`. If the result is `5.70.0`, that's very strange. Maybe they meant `5.6.0` -> `5.7.0` and they wanted `5.06.0` -> `5.07.0` but they got something else? Actually, read carefully: `current_version = "5.06.0"`. `serialize = ["{major}.{minor:02}.{patch}"]`. If we increase minor, it should go from `6` to `7`. The serialized version should be `5.07.0`. If they get `5.70.0`, maybe it's because they are using some other logic. Let's investigate how the version is parsed and serialized. The relevant files seem to be: - `bumpversion/version_part.py` - `bumpversion/versioning/serialization.py` - `bumpversion/versioning/models.py` - `bumpversion/versioning/functions.py` I'll start by searching for "serialize" and formatting logic in the codebase.<channel|><|tool_call>call:run_command{command:<|"|>grep -rn --include="*.py" "serialize" bumpversion/ | grep -v "tests"<|"|>}<tool_call|><|tool_response>

Wait, look at `VersionComponent.__format__`:

```python
    def __format__(self, format_spec: str) -> str:
        try:
            val = int(self.value)
        except ValueError:
            return self.value
        else:
            return int.__format__(val, format_spec)
```

This seems to correctly handle formatting if `self.value` can be converted to an integer.
If `self.value` is `"06"`, `int("06")` is `6`. Then `int.__format__(6, "02")` should be `"06"`.

The issue is that "Increasing minor would result in version 5.70.0".
Wait, if `current_version` is `5.06.0` and it's bumped to `5.07.0`.
The formatted version should be `5.07.0`.
Why would they get `5.70.0`?

Let's try to reproduce this.
I need a reproduction script. I'll use the configuration provided in the issue.
`current_version = "5.06.0"`
`parse = "(?P<major>\\d+)\\.(?P<minor>\\d+)\\.(?P<patch>\\d+)"`
`serialize = ["{major}.{minor:02}.{patch}"]`
`search = "{current_version}"`
`replace = "{new_version}"`

I will write a script to simulate the bump and serialization process.
Wait, look at `VersionComponent.__format__`: ```python def __format__(self, format_spec: str) -> str: try: val = int(self.value) except ValueError: return self.value else: return int.__format__(val, format_spec) ``` This seems to correctly handle formatting if `self.value` can be converted to an integer.

Wait, look at `Version.values()`:

```python
    def values(self) -> Dict[str, str]:
        \"\"\"Return the values of the parts.\"\"\"
        return {key: value.value for key, value in self.components.items()}
```

It returns `value.value`. And `VersionComponent.value` is:

```python
    @property
    def value(self) -> str:
        \"\"\"Return the value of the part.\"\"\"
        return self._value or self.func.optional_value
```

This is a `str`.
Now look back at `serialize` in `bumpversion/versioning/serialization.py`:

```python
    local_context = copy(context)
    local_context.update(version.values())
    # ...
    serialized = chosen_pattern.format(**local_context)
```

`local_context` now contains strings for the version parts.
When `chosen_pattern.format(**local_context)` is called, it's using strings in the format arguments.
Strings in Python's `.format()` do NOT support format specifiers like `:02`.
`:02` only works for numbers (integers, floats).

If `local_context['minor']` is `"06"`, and the pattern is `{minor:02}`, Python's `.format()` will raise a `ValueError` or just not work as expected if it's a string.
Actually, if you do `"{:02}".format("06")`, it works and produces `"06"`. But if you do `"{:02}".format("6")`, it produces `"60"`.
Wait, let's check that.
`"{:02}".format("6")` -> `'6 '` or something? No.
Let's check:
`"{:2}".format("6")` -> `' 6'` (right aligned, width 2)
`"{:02}".format("6")` -> `ValueError: Unknown format code '0' for object of type 'str'`

Ah! So if `local_context` has strings, `chosen_pattern.format(**local_context)` will FAIL if `:02` is used!
But the user says "Increasing minor would result in version 5.70.0".
Wait, if it doesn't raise a `ValueError`, what happens?
Actually, `"{:02}".format("6")` DOES raise `ValueError`.

Wait, maybe `localize_context` was intended to have `VersionComponent` objects, not their string values?
If `local_context` contained `VersionComponent` objects, then `VersionComponent.__format__` would be called.
And `VersionComponent.__format__` is defined as:

```python
    def __format__(self, format_spec: str) -> str:
        try:
            val = int(self.value)
        except ValueError:
            return self.value
        else:
            return int.__format__(val, format_spec)
```

This IS what we want!

So the bug is in `serialize` in `bumpversion/versioning/serialization.py` where it uses `version.values()` instead of the components themselves.
Wait, let's check `Version.values()` again.
```python
    def values(self) -> Dict[str, str]:
        \"\"\"Return the values of the parts.\"\"\"
        return {key: value.value for key, value in self.components.items()}
```
It returns the string values.

If `serialize` did:
```python
    local_context.update(version.components) # Use the VersionComponent objects
```
Then `chosen_pattern.format(**local_context)` would call `VersionComponent.__format__`.

Let's verify this with a reproduction script.

Wait, look at `Version.values()`: ```python def values(self) -> Dict[str, str]: \"\"\"Return the values of the parts.\"\"\" return {key: value.value for key, value in self.components.items()} ``` It returns `value.value`.

Wait, why?
Looking at the Python documentation for the `format()` function and the `format` mini-language.
If the value is a string, the format specifier `02` means:
- `0`: This is NOT a valid alignment for strings.

Wait, I just remembered something. In some contexts, if you provide a format spec that is not valid for the type, Python might behave strangely or raise an error.

Wait... is it possible that `02` for a string is interpreted as "width 2" and the `0` is just... I don't know.
Anyway, the point is that `local_context` contains strings, and when `.format()` is called on those strings, the result is NOT what we want.
If `local_context` contained the `VersionComponent` objects, it would call `VersionComponent.__format__`, which converts the value to an integer and then calls `int.__format__`.

So the fix is to pass the `VersionComponent` objects in `local_context` instead of their string values.

Let's verify this.

YES! That's it. `5.07.0`.
So the fix is to change `local_context.update(version.values())` to `local_context.update(version.components)` in `bumpversion/versioning/serialization.py`.

Wait, let's check if `version.components` is what I think it is.
In `Version.__init__`:
```python

    ):
        self.version_spec = version_spec
        self.components = components
```
Yes, `self.components` is a `Dict[str, VersionComponent]`.

To:

The `local_context` is passed to `chosen_pattern.format(**local_context)`.
If `local_context` values are `VersionComponent` objects, `.format()` will call `__format__` on them, which is exactly what we want.
If they were strings, `.format()` would just use the string.
So this is correct.
