System instructions 4,822 characters
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 that zero-padded version parts are not working.
Specifically, with `current_version = "5.06.0"` and `serialize = ["{major}.{minor:02}.{patch}"]`, incrementing the minor version results in `5.70.0` instead of `5.07.0`.

Wait, if the current version is `5.06.0` and we increment minor, it should be `5.07.0`.
The user says it results in `5.70.0`. This is very strange.
If the minor was `06` and incremented by 1, it should be `07`.
If it becomes `70`, it sounds like it's doing something weird.

Let's re-read.
`current_version = "5.06.0"`
`serialize = ["{major}.{minor:02}.{patch}"]`
`parse = "(?P<major>\\d+)\\.(?P<minor>\\d+)\\.(?P<patch>\\d+)"`

If `current_version` is `5.06.0`, then `major=5`, `minor=06`, `patch=0`.
Wait, `minor=06` parsed by `\d+` will likely be an integer `6`.
Incrementing `6` gives `7`.
Formatting `7` with `:02` should give `07`.
So the result should be `5.07.0`.
But the user says it's `5.70.0`.

Wait, let me re-read again.
"Increasing minor would result in version 5.70.0 which is obviously wrong."
Is it possible that `minor` is being treated as a string and something else is happening? Or maybe the `serialize` format is not being applied correctly?

Actually, if it results in `5.70.0`, maybe the `minor` became `70`?
`06` incremented by 1 is `7`.
How could it become `70`?
Wait, maybe they meant `5.07.0`?
Wait, "5.70.0". That's a big jump.
Maybe they meant `5.7.0`?
If they got `5.7.0`, then `:02` was ignored.
But they said `5.70.0`.

Let's try to reproduce this.

First, I'll search for where serialization happens.
`bumpversion/versioning/serialization.py` seems like a good place.
`bumpversion/version_part.py` might also be relevant.

I'll start by exploring the codebase.

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()}
```
The return type hint is `Dict[str, str]`.
If `value.value` is a string, then `.format(**local_context)` with `:02` won't work as expected for numbers.
Actually, if you try to format a string with `:02`, it might fail or do something else.

Let's check `VersionComponent`.

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()} ``` The return type hint is `Dict[str, str]`. If `value.value` is a string, then `.format(**local_context)` with `:02` won't work as expected for numbers. Actually, if you try to format a string with `:02`, it might fail or do something else. Let's check `VersionComponent`. <channel|><|tool_call>call:read_file{filepath:<|"|>bumpversion/versioning/models.py<|"|>,start_line:16}<tool_call|><|tool_response>

Wait, `VersionComponent` has a `__format__` method!
```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 great. If the object passed to `.format()` is a `VersionComponent` object, then `:02` will work.

But `Version.values()` does this:
```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` which is a `str` (as seen in `VersionComponent.value` property).
Because it returns strings, the `__format__` method of `VersionComponent` is never used when `serialize` does:
```python
    local_context.update(version.values())
    # ...
    serialized = chosen_pattern.format(**local_context)
```
`local_context` now contains the strings, not the `VersionComponent` objects.

To fix this, `Version.values()` should return the `VersionComponent` objects themselves, not their string values.

Let's verify this with a reproduction.
I'll create a script that mimics the configuration provided by the user.
`current_version = "5.06.0"`
`parse = "(?P<major>\\d+)\\.(?P<minor>\\d+)\\.(?P<patch>\\d+)"`
`serialize = ["{major}.{minor:02}.{patch}"]`

I need to see how these are used to create a `Version` object.
I'll try to use the library to reproduce it.

Wait, I don't know the exact API for creating a `Version` object from a config, but I can try to use `bumpversion`'s internals.

Actually, the simplest way is to write a small script that uses `VersionComponent` and the `serialize` function.

Ah, `Context` is not in `bumpversion.context` or it's named differently. I don't actually need `Context` if I just pass an empty dict.

Let's try again. Also, I need to make sure `VersionSpec` is initialized correctly.

Okay, `VersionSpec` doesn't have a `components` attribute. It probably just stores them in `self.components` in `__init__`. Wait, let's check `VersionSpec.__init__` in `bumpversion/versioning/models.py`.

This is insane. In Python 3.10, `f"{s:02}"` where `s="7"` shouldraise `ValueError`.

Wait! I suspect I know what's happening.
I'm not using `python3` the way I think I am.
But `python3 --version` said `3.10.19`.

Regardless of why it's happening (maybe it's a weird Python build in this environment), the core issue is that `Version.values()` returns strings, and when these strings are used with `:02` in `.format()`, they are not zero-padded as intended (they are either failing or being padded incorrectly if they are strings).

Wait, if `VersionComponent` has a `__format__` method:
```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)
```
Then if we pass the `VersionComponent` object itself to `.format()`, it will call this `__format__` method, which will then call `int.__format__(val, format_spec)`, which IS the correct way to zero-pad an integer.

So the fix is definitely to make `Version.values()` return the `VersionComponent` objects instead of their string values.

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()}
```
We should change it to:
```python
    def values(self) -> Dict[str, VersionComponent]:
        \"\"\"Return the components of the version.\"\"\"
        return self.components
```

But wait, `Version.values()` is used in other places. If other code expects strings, this might break things.
Let's search for usages of `version.values()`.

Wait, `bumpversion/show.py:19: print_info(next(iter(value.values())))`. Let's see `bumpversion/show.py`. <channel|><|tool_call>call:read_file{filepath:<|"|>bumpversion/show.py<|"|>,start_line=10,end_line=30}<tool_call|><|tool_response>

In `bumpversion/show.py`:
```python
def output_default(value: dict) -> None:
    """Output the value with key=value or just value if there is only one item."""
    if len(value) == 1:
        print_info(next(iter(value.values())))
```
Wait, the `value` passed to `output_default` is `show_items`, which comes from `config_dict` or `resolve_name(config_dict, key)`.
`config_dict = config.model_dump()`.
`config` is a `Config` object. Let's see where `config_dict` is created.
The `value.values()` in `print_info(next(iter(value.values())))` is NOT referring to `Version.values()`. It's referring to a dictionary's `.values()` method.

So `bumpversion/show.py` is irrelevant.

What about `bumpversion/versioning/models.py:281: unique_dependents = set(chain.from_iterable(dependents.values()))`?
`dependents` is probably a dict of lists. `.values()` is the dict method.

So the ONLY place where `Version.values()` is actually called as a method of a `Version` object is `bumpversion/versioning/serialization.py:106`:
```python
    local_context.update(version.values())
```

If we change `Version.values()` to return `VersionComponent` objects, `local_context` will contain `VersionComponent` objects.
Then `serialize` does:
```python
    return self.format_.format(**local_context)
```
And `.format()` will call `VersionComponent.__format__`, which is exactly what we want!

Since no other code seems to be using `Version.values()` in a way that expects strings (as far as the grep showed, and the `show.py` check confirmed), this is a safe change.

Wait, I should double check if any other `Version` method returns strings that might be used for formatting.
No, `serialize` specifically uses `version.values()`.

Let's implement the fix.
