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 an issue where zero-padded version parts are not working as expected.
The example provided is:
`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}"`

When increasing the minor version, the user says the result is `5.70.0` (wait, 5.06.0 -> 5.7.0 maybe? Or if they incremented it many times? If they increment 5.06.0 minor once, it should be 5.07.0. If they say it becomes 5.70.0, maybe they meant 5.7.0? No, "5.70.0" probably means it's treating 06 as 6 and then formatting it somehow? Or maybe they meant 5.7.0).

Wait, if current is 5.06.0 and they increase minor:
6 -> 7.
Format `{minor:02}` should make it `07`.
Result: `5.07.0`.

If the result is `5.70.0`, that's very weird. Maybe they meant `5.7.0`?
"Increasing minor would result in version 5.70.0 which is obviously wrong."
Actually, if the current version is 5.06.0, and you increment minor, it should be 5.07.0.
If it becomes 5.7.0, that's a failure of zero-padding.
If it becomes 5.70.0, maybe it's adding 10? No, they said "Increasing minor".

Let's look at the config: `serialize = ["{major}.{minor:02}.{patch}"]`.
This looks like a python format string.

I need to find where the version is serialized.
Looking at the file list, `bumpversion/versioning/serialization.py` seems like the most relevant place.

Let's start by exploring the code.

The core logic is here:
```python
    local_context = copy(context)
    local_context.update(version.values())
    # ...
    serialized = chosen_pattern.format(**local_context)
```
`version.values()` likely returns the parts of the version. In the user's example, these would be `major`, `minor`, and `patch`.
The user says they have `serialize = ["{major}.{minor:02}.{patch}"]`.
If `version.values()` returns strings, then `.format(**local_context)` will fail or not apply the `:02` formatting because `:02` is for integers.

Let's check `bumpversion/versioning/models.py` to see what `Version.values()` returns.

The core logic is here: ```python local_context = copy(context) local_context.update(version.values()) # ... serialized = chosen_pattern.format(**local_context) ``` `version.values()` likely returns the parts of the version. In the user's example, these would be `major`, `minor`, and `patch`. The user says they have `serialize = ["{major}.{minor:02}.{patch}"]`. If `version.values()` returns strings, then `.format(**local_context)` will fail or not apply the `:02` formatting because `:02` is for integers. Let's check `bumpversion/versioning/models.py` to see what `Version.values()` returns. <channel|><|tool_call>call:read_file{filepath:<|"|>bumpversion/versioning/models.py<|"|>}<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 exactly what is needed for zero-padding! `int.__format__(val, "02")` will produce `02` if `val` is `2`.

However, `Version.values()` in `serialize` is likely returning the values of the components, not the components themselves.

Let's check `Version` class in `bumpversion/versioning/models.py`.

Found it!
```python
class Version:
    # ...
    def values(self) -> Dict[str, str]:
        """Return the values of the parts."""
        return {key: value.value for key, value in self.components.items()}
```
`value.value` returns a string.
And `ValueComponent.value` is:
```python
    @property
    def value(self) -> str:
        """Return the value of the part."""
        return self._value or self.func.optional_value
```
So `Version.values()` returns a dictionary of strings. When this is passed to `chosen_pattern.format(**local_context)`, the `format_spec` (like `:02`) is applied to the string, which doesn't do zero-padding for numbers.

To fix this, `Version.values()` should probably return the `VersionComponent` objects themselves, so that `VersionComponent.__format__` can be used.

Wait, `Version.values()` is typed as `Dict[str, str]`. Let's see where else it is used.
It's used in `bumpversion/versioning/serialization.py`:
```python
    local_context = copy(context)
    local_context.update(version.values())
```
If `version.values()` returns `Dict[str, VersionComponent]`, then `local_context` will have `VersionComponent` objects, and `.format()` will call `VersionComponent.__format__`.

Let's check if `Version.values()` is used anywhere else.

In `bumpversion/show.py`, `output_default` is called with `show_items`, which is either `config_dict` or a subset of it. `config_dict` comes from `config.model_dump()`.
The `version.values()` usage I saw in `grep` was:
`bumpversion/show.py:19:        print_info(next(iter(value.values())))`
Wait, `value` there is a `dict`. `value.values()` is a method of `dict`.
So the `grep` result `bumpversion/show.py:19` was NOT calling `Version.values()`.

So it seems `Version.values()` is ONLY used in `bumpversion/versioning/serialization.py`.

Let's double check.

In `bumpversion/versioning/models.py:281`, `dependents` is a dict.
In `bumpversion/show.py:19`, `value` is a dict.
So ONLY `bumpversion/versioning/serialization.py:106` calls `version.values()` where `version` is an instance of `Version`.

So, changing `Version.values()` to return the `VersionComponent` objects instead of their string values should work and not break anything.

Let's verify this with a reproduction script.

The user said:
`current_version = "5.06.0"`
`parse = "(?P<major>\\d+)\\.(?P<minor>\\d+)\\.(?P<patch>\\d+)"`
`serialize = ["{major}.{minor:02}.{patch}"]`

If we increase minor, we should get `5.07.0`.

Wait, I got `5.70.0`? Why `5.70.0`?
Ah! I know why.
The current version is `5.06.0`.
When we bump `minor`, `06` becomes `7`. (Or maybe `6` becomes `7`).
Wait, `VersionComponent.bump()` calls `self.func.bump(self.value)`.
For `NumericFunction`, `bump` probably does:
```python
    def bump(self, value: str) -> str:
        return str(int(value) + 1)
```
So `06` becomes `7`.
And then it's serialized using `"{major}.{minor:02}.{patch}"`.
If `minor` is the string `"7"`, then `"7":02` formatting for a string does... what?
Wait, `"{:02}".format("7")` would actually raise a `ValueError: Unknown format code '0' for object of type 'str'`.

Let's check what happened in my reproduction.
`Next: 5.70.0`
Wait, `5.70.0`?
If `major` is `5`, `minor` is `7`, and `patch` is `0`.
The result was `5.70.0`.
That means `major` was `5`, `minor` was `7`, and `patch` was `0`.
So it was `5` + `.` + `7` + `0` + `.` + `0`? No, `5.70.0`.
Maybe `patch` was `0` and `minor` was `7`, and the format was `{major}.{minor}{patch}.{something}`? No.

Wait, let me re-read the reproduction output.
`Current: 5.06.0`
`Next: 5.70.0`

Wait, the format I used was `{major}.{minor:02}.{patch}`.
If `major="5"`, `minor="7"`, `patch="0"`.
`"5".format(...)` is not what happened.
It was `{major}.{minor:02}.{patch}`.
If `minor` is a string `"7"`, `"{:02}".format("7")` should fail.

Let's test this in a simple python script.

Okay, so `{:2}` is `"a "`.
And `{:02}` is `"a0"`.
This is... not standard Python.
Wait, let me check if this is some weird shell expansion or something. No, it's inside `python3 - <<'PY'`.

Let me try this in a different way.
`python3 -c 'print(f"{\"a\":02}")'` - no.

Let me try this:
`python3 -c 'print("{:02}".format("a"))'`

This is insane. I've never seen Python do this.
Wait, let me check the Python version again. `3.10.19`.
Wait... I just realized. If I'm in a weird environment, maybe I should just stop worrying about *why* it's happening and focus on the fix.
The fix is to make `minor` an integer (or something that handles `{:02}` correctly, like `VersionComponent` which I'm told implements `__format__`).

Wait, if `VersionComponent` implements `__format__`, let's see how it does it.
I'll read `bumpversion/versioning/models.py`.

This is exactly what we need. If `Version.values()` returns the `VersionComponent` objects, then `"{minor:02}".format(**version.values())` will call `VersionComponent.__format__("02")`, which will convert the value to `int` and format it using `int.__format__`, resulting in `"07"`.

Let's analyze these:
1. `./bumpversion/versioning/models.py:281`: `dependents.values()` where `dependents` is a dict. (Correct)
2. `./bumpversion/versioning/serialization.py:106`: `version.values()`. (This is the target!)
3. `./bumpversion/show.py:19`: `value.values()` where `value` is... what? Let's check `bumpversion/show.py`.
4. Tests are ignored.

Let's analyze these: 1. `./bumpversion/versioning/models.py:281`: `dependents.values()` where `dependents` is a dict. (Correct) 2. `./bumpversion/versioning/serialization.py:106`: `version.values()`. (This is the target!) 3. `./bumpversion/show.py:19`: `value.values()` where `value` is... what? Let's check `bumpversion/show.py`. 4. Tests are ignored. Let's check `bumpversion/show.py:19`. <channel|><|tool_call>call:read_file{end_line:30,filepath:<|"|>bumpversion/show.py<|"|>,start_line:10}<tool_call|><|tool_response>

In `bumpversion/show.py`, `output_default(value: dict)` is called.
If `len(value) == 1`, it prints `next(iter(value.values()))`.
Since `value` is a `dict`, `value.values()` is the dictionary's values view, not `Version.values()`.
So `bumpversion/show.py` is fine.

So the only place `Version.values()` is called is `bumpversion/versioning/serialization.py:106`.

Let's apply the fix.

Wait, I should also update the type hint from `Dict[str, str]` to `Dict[str, VersionComponent]`.

The reproduction script now passes!
Let's check for any other potential issues.
Wait, I used `VersionComponent` in the type hint `Dict[str, "VersionComponent"]`.
Is `VersionComponent` defined and available in the scope where `Version.values` is?
Yes, `VersionComponent` is defined before `Version` in `bumpversion/versioning/models.py`.
I used a string literal `"VersionComponent"` just in case of circularity, but it should be fine.
Actually, it's defined at line 16, and `Version` is at line 207. So it's fine.

One more check: did I break anything else?
I should run existing tests for `bumpversion.versioning.serialization` and `bumpversion.versioning.models`.
