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.

## 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 the `cassandra_port` configuration is not being used when using the Cassandra result backend.
The error message shows that the client is trying to connect to `localhost:9042` (the default Cassandra port) even though `cassandra_port` is set to `'61003'`.

I need to find where the Cassandra backend is implemented and check how it uses the `cassandra_port` configuration.

Looking at the workspace layout, the most likely file is `celery/backends/cassandra.py`.

In `__init__`, I see:
```python
    def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
                 port=9042, bundle_path=None, **kwargs):
        super().__init__(**kwargs)

        if not cassandra:
            raise ImproperlyConfigured(E_NO_CASSANDRA)

        conf = self.app.conf
        self.servers = servers or conf.get('cassandra_servers', None)
        self.bundle_path = bundle_path or conf.get(
            'cassandra_secure_bundle_path', None)
        self.port = port or conf.get('cassandra_port', None)

        self.table = table or conf.get('cassandra_table', None)
        self.cassandra_options = conf.get('cassandra_options', {})\n
```

The `port` parameter defaults to `9042`.
The line `self.port = port or conf.get('cassandra_port', None)` means:
If `port` is provided (and is truthy), use `port`.
Otherwise, try to get `cassandra_port` from configuration.
If `cassandra_port` is not provided, `self.port` will be `None`.

However, `port` defaults to `9042`, so `port or conf.get('cassandra_port', None)` will always be `9042` (since 9042 is truthy), UNLESS `port` is passed as something falsy (like `None` or `0` or `""`).

When the result backend is instantiated by Celery, it probably doesn't pass `port` explicitly, so it uses the default value `9042`. Thus, `conf.get('cassandra_port', None)` is never reached.

Let's see how `Cluster` is initialized. I'll search for where `self.port` is used in `celery/backends/cassandra.py`.

Wait, if `port` is passed as `9042` to `__init__`, then `self.port` becomes `9042`.
If the user sets `cassandra_port = '61003'` in their config, the current code does:
`self.port = 9042 or '61003'` which result in `9042`.

This is exactly the bug. The default value of the `port` argument in `__init__` should not be `9042` if we want to allow the configuration to override it. Or the logic should be changed to prioritize the configuration over the default argument.

Actually, the usual pattern in Celery backends for this is to set the default value to `None` in the signature, and then handle the default logic inside the method.

Let's verify this. If I change `port=9042` to `port=None` in `__init__`, then:
`self.port = port or conf.get('cassandra_port', None)`
If `port` is `None`, it will use `conf.get('cassandra_port', None)`.
If `cassandra_port` is also not set, `self.port` will be `None`.
Then `cassandra.cluster.Cluster(self.servers, port=self.port, ...)` will be called with `port=None`.
Does `cassandra.cluster.Cluster` handle `port=None` by using its own default (which is likely 9042)?
Most probably yes.

Let's check if there is any other place where `port` is used.
The issue report shows `cassandra_port: '61003'`. It's a string.

If I change:
```python
    def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
                 port=9042, bundle_path=None, **kwargs):
```
to
```python
    def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
                 port=None, bundle_path=None, **kwargs):
```
And `self.port = port or conf.get('cassandra_port', None)` would then result in `None` if neither is provided.

Let's see if I should provide a default fallback for `self.port`.
If `cassandra.cluster.Cluster` handles `port=None` and defaults to 9042, then we are good.

Wait, the `cassandra-driver` docs (which `cassandra.cluster.Cluster` belongs to) usually default the port to 9042 if not specified.

Let's double check the `Cluster` initialization in `celery/backends/cassandra.py`.

```python
            if self.servers:
                self._cluster = cassandra.cluster.Cluster(
                    self.servers, port=self.port,
                    auth_provider=self.auth_provider,
                    **self.cassandra_options)
```

If `self.port` is `None`, then `Cluster(self.servers, port=None, ...)` is called.

Let's verify the reproduction. Since I don't have a Cassandra server, I can't run the tests that actually connect to one. But I can check if I can mock it.

Wait, I can just see if there's a test for Cassandra backend.

Wait, if `port` is passed as `9042` to `__init__`, then `self.port` becomes `9042`. If the user sets `cassandra_port = '61003'` in their config, the current code does: `self.port = 9042 or '61003'` which result in `9042`. This is exactly the bug. The default value of the `port` argument in `__init__` should not be `9042` if we want to allow the configuration to override it. Or the logic should be changed to prioritize the configuration over the default argument. Actually, the usual pattern in Celery backends for this is to set the default value to `None` in the signature, and then handle the default logic inside the method. Let's verify this. If I change `port=9042` to `port=None` in `__init__`, then: `self.port = port or conf.get('cassandra_port', None)` If `port` is `None`, it will use `conf.get('cassandra_port', None)`. If `cassandra_port` is also not set, `self.port` will be `None`. Then `cassandra.cluster.Cluster(self.servers, port=self.port, ...)` will be called with `port=None`. Does `cassandra.cluster.Cluster` handle `port=None` by using its own default (which is likely 9042)? Most probably yes. Let's check if there is any other place where `port` is used. The issue report shows `cassandra_port: '61003'`. It's a string. If I change: ```python def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None, port=9042, bundle_path=None, **kwargs): ``` to ```python def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None, port=None, bundle_path=None, **kwargs): ``` And `self.port = port or conf.get('cassandra_port', None)` would then result in `None` if neither is provided.

`BaseBackend` also uses `self.accept`, which is derived from `conf.accept_content`.
I'm spending too much time trying to setup the full `app` and `conf` objects for a unit test. I can just mock `CassandraBackend.__init__`'s call to `super().__init__` and `conf.get`.

Wait, easier: I'll just mock the elements of `self.app.conf` and avoid calling `super().__init__` or just mock it.
Actually, the simplest way is to just use `unittest.mock.patch` to mock `super().__init__`.

But better yet, let's look at the code.
```python
    def __init__(self, servers=None, keyspace=None, table=None, entry_ttl=None,
                 port=9042, bundle_path=None, **kwargs):
        super().__init__(**kwargs)
```
If I don't pass any `kwargs`, `super().__init__` is called with nothing.

Let's try to just instantiate it and mock `self.app`.

It seems `self.accept` is being set to a `Mock` object in `BaseBackend.__init__` because `conf.accept_content` is a `Mock` object? No, I set `conf.accept_content = ['json']`.

Wait, `BaseBackend.__init__` probably does:
```python
        self.accept = conf.accept_content
```
And then calls `prepare_accept_content(self.accept)`.

Wait, I'm using `conf = Mock()`.
So `conf.accept_content` is a `Mock` if not explicitly set?
But I did `conf.accept_content = ['json']`.

Let's read `celery/backends/base.py`.

I see:
```python
        # precedence: accept, conf.result_accept_content, conf.accept_content
        self.accept = conf.result_accept_content if accept is None else accept
        self.accept = conf.accept_content if self.accept is None else self.accept
        self.accept = prepare_accept_content(self.accept)
```

In my test:
```python
    conf = Mock()
    # ...
    conf.accept_content = ['json']
```
Since `conf` is a `Mock`, `conf.result_accept_content` will also be a `Mock` object.
So `self.accept` starts as `conf.result_accept_content` (a `Mock` object).
Then `self.accept = conf.accept_content if self.accept is None else self.accept`.
But `self.accept` is NOT `None`, it's a `Mock` object.
So `self.accept` remains a `Mock` object.
Then `prepare_accept_content(self.accept)` is called, and it fails because the `Mock` object is not iterable.

Anyway, let's just bypass `super().__init__` by patching it.

This is becoming a rabbit hole of mocking `BaseBackend`.

Let's just use the `unittest.mock.MagicMock` for `conf` but make sure it doesn't return `MagicMock` objects for everything.

Actually, I can just patch `BaseBackend.__init__` and manually set the attributes that `CassandraBackend` needs from it.

`CassandraBackend.__init__`:
```python
    def __init__(self, app, port=9042, **kwargs):
        self.app = app
        conf = self.app.conf
        self.port = port or conf.get('cassandra_port', None)
        self.keyspace = conf.get('cassandra_keyspace')
        self.table = conf.get('cassandra_table')
        # ...
        super().__init__(**kwargs)
```

It doesn't seem to rely on any attributes set by `BaseBackend.__init__` *except* that `BaseBackend.__init__` might be doing things I don't know about. But wait, `CassandraBackend` doesn't seem to use `self.serializer`, `self.expires`, etc. before `super().__init__`.

Let's just mock `BaseBackend.__init__` and NOT set `self.app = app` *before* calling it, but `CassandraBackend` already does `self.app = app`.

Wait, if I patch `BaseBackend.__init__`, then `self.app = app` in `CassandraBackend.__init__` should be enough.

Wait, I am confused.
```python
    def __init__(self, app, port=9042, **kwargs):
        self.app = app
        conf = self.app.conf
```
Line 95 is `conf = self.app.conf`.
Wait, if `CassandraBackend(app=app)` is called, then `app` is passed as a keyword argument `app`.
But the signature is `def __init__(self, app, port=9042, **kwargs):`.
If I call `CassandraBackend(app=app)`, then `app` (the first positional argument) is missing, and `app` goes into `kwargs`.

So when the function starts:
`self` = self
`app` = (missing, but let's see)
Actually, if I call `CassandraBackend(app=app)`, and the definition is `def __init__(self, app, port=9042, **kwargs):`, then `app` is a required positional argument.

If I call `CassandraBackend(app=app)`, then `app` (positional) is NOT provided. Python will then try to find `app` in the keyword arguments and assign it to the `app` parameter. So it should work.

Wait, if I call `CassandraBackend(app=app)`, then:
`self` gets the instance.
`app` gets the value of the keyword argument `app`.
`port` gets `9042`.
`kwargs` gets any other keyword arguments.

Let me check the traceback again.
`File "/workspace/celery/backends/cassandra.py", line 95, in __init__`
`conf = self.app.conf`
`AttributeError: 'CassandraBackend' object has no attribute 'app'`

This means `self.app = app` (line 94) did not work or was not executed.

Wait, I see the code in `read_file`:
```python
    def __init__(self, app, port=9042, **kwargs):
        self.app = app
        conf = self.app.conf
```

If I call `CassandraBackend(app=app)`, it should work.

Hold on, is it possible that `CassandraBackend` is not the class I think it is? No, it's imported.

Wait, I see!
`with patch('celery.backends.base.BaseBackend.__init__', return_value=None):`

When `super().__init__(**kwargs)` is called inside `CassandraBackend.__init__`, it calls the patched `BaseBackend.__init__`.

But the error happens at line 95, WHICH IS BEFORE `super().__init__(**kwargs)` (which is at line 90 in the previous traceback, but let's check the current one).

Wait, looking at my previous `read_file`:
Lines 88-98:
```python
    def __init__(self, app, port=9042, **kwargs):
        self.app = app
        conf = self.app.conf
        self.port = port or conf.get('cassandra_port', None)
        self.keyspace = conf.get('cassandra_keyspace')
        self.table = conf.get('cassandra_table')
        self.options = conf.get('cassandra_options', {})
        self.cluster = None
        self.session = None
        super().__init__(**kwargs)
```

Wait, if I call `backend = CassandraBackend(app=app)`, why does `self.app = app` fail?

Ah! I know why!
In my test:
```python
        with patch('celery.backends.base.BaseBackend.__init__', return_value=None):
            backend = CassandraBackend(app=app)
```
The `patch` is wrapping the call.

Wait... look at the traceback:
`File "/workspace/celery/backends/cassandra.py", line 95, in __init__`
`conf = self.app.conf`
`AttributeError: 'CassandraBackend' object has no attribute 'app'`

Line 94 is `self.app = app`.
If line 95 fails with `AttributeError: 'CassandraBackend' object has no attribute 'app'`, it means line 94 didn't execute or `self` is not what I think it is.

Wait, if I'm using `unittest.mock.patch`, it shouldn't affect the `__init__` of `CassandraBackend` itself.

Let's try to reproduce WITHOUT the `BaseBackend.__init__` patch first, and just fix the `Conf` class's missing attributes.

Ah, I might have missed the space or the indentation. Let me double check the `read_file` output.

```python

        conf = self.app.conf
        self.port = port or conf.get('cassandra_port', None)
```

Let's try with just the signature and the first line of the body.
