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 M0r13n/pyais.

Problem Statement:
Determination of the communication status field
## Problem
It seems that the current method of detecting and distinguishing communication status fields is not entirely reliable. For example, the following example incorrectly indicates that it is a SOTDMA communication status, although it is an ITDMA.
```python
decoded = pyais.decode('!AIVDM,1,1,,A,333ga6PP0jPPDUNM3I7DTOwDR59C,0*51')
com = decoded.get_communication_state()
print(f"SOTDMA: {decoded.is_sotdma}, ITDMA: {decoded.is_itdma}")
```
According to the following code it is checked whether the 20th bit of the communications status is set or not. However, as the com state is only 19 bits long, a bit from the previous data fields is checked here and not one from the com state. In the case of a type 1, 2 or 3 message, it would be checked whether the RAIM flag is set. Since 1 is the default value, pyais returns in almost all cases that it is a SOTDMA com state.
```python
@property
def is_sotdma(self) -> bool:
    """The radio status field has it's 20th bit (MSB) set to 0 or has less than 20 bits"""
    return self.radio <= self.MAX_COMM_STATE_VALUE

@property
def is_itdma(self) -> bool:
    """The radio status field has it's 20th bit (MSB) set to 1"""
    return self.radio > self.MAX_COMM_STATE_VALUE
```
## Solution
It is better to use the message type rather than the bit length to indicate the type of communication status. Table 46 of the M.1371-5 standard shows which type uses which com state. Type 9, 18 and 26 messages are edge cases, as they can include one of the two com state types. The existing implementation can be used here, as with these message types the bit before the actual com state determines its type.

## 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.
## Workspace Layout
The repository is located at `/workspace`. Here is the directory tree (up to 3 levels):

The user is reporting a bug in the communication status field detection in `pyais`.
Specifically, `is_sotdma` and `is_itdma` properties are incorrectly implemented.
They are currently checking the 20th bit of the communication state, but since the communication state is only 19 bits long, they are actually checking a bit from the previous data field.

The suggested solution is to use the message type to determine the type of communication status, except for types 9, 18, and 26 where the existing bit-check logic might still be applicable (or should be refined).

Let's start by exploring the code to locate the `is_sotdma` and `is_itdma` properties.

Based on the problem description, these properties seem to be part of a decoded message class. I'll look for them in `pyais/messages.py` or `pyais/decode.py`.

Actually, the description shows:
```python
@property
def is_sotdma(self) -> bool:
    """The radio status field has it's 20th bit (MSB) set to 0 or has less than 20 bits"""
    return self.radio <= self.MAX_COMM_STATE_VALUE

@property
def is_itdma(self) -> bool:
    """The radio status field has it's 20th bit (MSB) set to 1"""
    return self.radio > self.MAX_COMM_STATE_VALUE
```
I'll search for these strings.

Wait, let me check `pyais/messages.py` again. ```python class MessageType1(Payload, CommunicationStateMixin): """ AIS Vessel position report using SOTDMA (Self-Organizing Time Division Multiple Access) ``` And Message 4? <channel|><|tool_call>call:run_command{command:<|"|>grep -A 2 "class MessageType4" pyais/messages.py<|"|>}<tool_call|><|tool_response>

Wait, the docstring for `MessageType4` also says "using SOTDMA"? That's strange. Let me read more.

Actually, that might be a copy-paste error in the docstrings.
Let me read the file more carefully around `MessageType4`.

And `MessageType3`'s docstring says:
```python
class MessageType3(MessageType1):
    """
    AIS Vessel position report using ITDMA (Incremental Time Division Multiple Access)
    Src: https://gpsd.gitlab.io/gpsd/AIVDM.html#_types_1_2_and_3_position_report_class_a
    """
    msg_type = bit_field(6, int, default=3)
```
Wait, that's interesting. `MessageType3` inherits from `MessageType1`.

Let's check the `MessageType1` definition again. It defines a bunch of `bit_field`s.
The `radio` field is defined in `MessageType1`? Let me check.

Looking at the output of `read_file` for lines 860-900, I see:
```python
    raim = bit_field(1, bool, default=0)
    radio = bit_field(19, int, default=0, signed=False)
```
This is just BEFORE `class MessageType2(MessageType1):`. So these fields are in `MessageType1`.

Wait, the problem says: "In the case of a type 1, 2 or 3 message, it would be checked whether the RAIM flag is set. Since 1 is the default value, pyais returns in almost all cases that it is a SOTDMA com state."

If `is_sotdma` is:
```python
    @property
    def is_sotdma(self) -> bool:
        """The radio status field has it's 20th bit (MSB) set to 0 or has less than 20 bits"""
        return self.radio <= self.MAX_COMM_STATE_VALUE
```
And `MAX_COMM_STATE_VALUE = 0x7ffff` (which is $2^{19}-1$).
If `self.radio` is 19 bits, the max value is $2^{19}-1$. So `self.radio` will always be `<= 0x7ffff`.

Wait, if the 20th bit is set, then `self.radio` would be $\ge 2^{19}$ ($0x80000$).
But `radio` is defined as `bit_field(19, int, ...)`. So `pyais` only reads 19 bits into `self.radio`.
The 20th bit is the `raim` field!
```python
    raim = bit_field(1, bool, default=0)
    radio = bit_field(19, int, default=0, signed=False)
```
Wait, in `MessageType1` (and 2, 3), the fields are:
...
`raim` (1 bit)
`radio` (19 bits)

If the implementation of `is_sotdma` was intended to check the 20th bit of a combined field, it failed because it only checked `self.radio`.
Wait, the problem says "it is checked whether the 20th bit of the communications status is set or not. However, as the com state is only 19 bits long, a bit from the previous data fields is checked here and not one from the com state."

If `self.radio` is 19 bits, it can NEVER have the 20th bit set.
But wait, let's look at the code again.
```python
    @property
    def is_sotdma(self) -> bool:
        """The radio status field has it's 20th bit (MSB) set to 0 or has less than 20 bits"""
        return self.radio <= self.MAX_COMM_STATE_VALUE
```
`self.MAX_COMM_STATE_VALUE` is `0x7ffff` (19 bits set to 1).
If `self.radio` is only 19 bits, it will ALWAYS be `<= 0x7ffff`.
So `is_sotdma` will ALWAYS be `True`.

This matches the observation: "pyais returns in almost all cases that it is a SOTDMA com state."

Now, what should the fix be?
"It is better to use the message type rather than the bit length to indicate the type of communication status."

So I need a mapping:
- Message Type 1, 2 -> SOTDMA
- Message Type 3 -> ITDMA
- Message Type 4 -> ITDMA (Wait, is it? Let me check)
- Message Type 9, 18, 26 -> Use current bit-based logic (but the bit-based logic is currently wrong).

Wait, the user said: "Type 9, 18 and 26 messages are edge cases... The existing implementation can be used here, as with these message types the bit before the actual com state determines its type."

Wait, if the "existing implementation" is `self.radio > self.MAX_COMM_STATE_VALUE`, but `self.radio` is only 19 bits... then it still won't work.
Unless for types 9, 18, and 26, `self.radio` is defined as 20 bits?

Let's check `MessageType9`, `MessageType18`, `MessageType26` in `pyais/messages.py`.

Yes, `MessageType18` also has `radio = bit_field(20, int, default=0)`. Now let's check `MessageType26`. <channel|><|tool_call>call:read_file{end_line:1620,filepath:<|"|>pyais/messages.py<|"|>,start_line:1540}<tool_call|><|tool_response>

Yes, all `MessageType26` variants also use `radio = bit_field(20, int, default=0, signed=False)`.

So the rule is:
- For message types 1, 2, 3, 4, 11 (and others that use `CommunicationStateMixin` but `radio` is only 19 bits):
  - Type 1, 2 -> SOTDMA
  - Type 3, 4, 11 -> ITDMA (Wait, I need to confirm this. The problem says 1, 2, 3 are a group and 4 is another. "In the case of a type 1, 2 or 3 message, it would be checked whether the RAIM flag is set.")

Let's look at the AIS standard (or common knowledge about it).
- Type 1, 2: SOTDMA (Class A position report)
- Type 3: ITDMA (Class A position report)
- Type 4: ITDMA (Base station report)

Wait, the docstring for `MessageType1` said SOTDMA.
Docstring for `MessageType3` said ITDMA.
Docstring for `MessageType4` said SOTDMA (which I suspect is a mistake).

Let's verify if Type 4 is ITDMA.
From GPSD: "Type 4 base station report". Base stations typically use ITDMA or are the master.
Actually, let's look at the problem description again.
"It is better to use the message type rather than the bit length to indicate the type of communication status."

If I change `is_sotdma` and `is_itdma` to check the message type, I need to be sure about which types are which.

Wait, if I look at `CommunicationStateMixin`, it's used by:
- MessageType 1, 2, 3 (1, 2 are SOTDMA, 3 is ITDMA)
- MessageType 4, 11 (4 is base station report, likely ITDMA)
- MessageType 9, 18, 26 (Edge cases, use bit logic)

Wait, the user says: "The existing implementation can be used here [for 9, 18, 26], as with these message types the bit before the actual com state determines its type."
Wait, no. He said "The existing implementation can be used here, as with these message types the bit before the actual com state determines its type."
But the existing implementation used `self.radio`, and for types 9, 18, 26, `self.radio` is 20 bits.
So `self.radio > 0x7ffff` is exactly checking that 20th bit!

So the fix is:
1. For types 9, 18, 26: Keep using `self.radio > 0x7ffff`.
2. For other types: Use the message type to decide.

Which other types are there?
Looking at `pyais/messages.py`:
- `MessageType1`
- `MessageType2` (inherits from 1)
- `MessageType3` (inherits from 1)
- `MessageType4`
- `MessageType9`
- `MessageType11` (inherits from 4)
- `MessageType18`
- `MessageType26...`

So for `MessageType1` and `MessageType2`, `is_sotdma` should be `True`.
For `MessageType3`, `MessageType4`, `MessageType11`, `is_sotdma` should be `False`.

Let's double check if there are any others.
`MessageType1` inherits `CommunicationStateMixin`. `MessageType2` and `3` inherit from `MessageType1`.
`MessageType4` inherits `CommunicationStateMixin`. `MessageType11` inherits from `MessageType4`.
`MessageType9` inherits `CommunicationStateMixin`.
`MessageType18` inherits `CommunicationStateMixin`.
`MessageType26...` inherit `CommunicationStateMixin`.

So the mapping seems to be:
- `MessageType1`, `MessageType2` -> SOTDMA
- `MessageType3`, `MessageType4`, `MessageType11` -> ITDMA
- `MessageType9`, `MessageType18`, `MessageType26*` -> Bit-based check.

Wait, is there any other `MessageType` that inherits from `CommunicationStateMixin`?
Let's check the whole file for `CommunicationStateMixin`.

Yes, those are all.

So, let's refine the implementation of `is_sotdma`:
```python
    @property
    def is_sotdma(self) -> bool:
        if isinstance(self, (MessageType1, MessageType2)):
            return True
        if isinstance(self, (MessageType3, MessageType4, MessageType11)):
            return False
        # Fallback for 9, 18, 26 and any others
        return self.radio <= self.MAX_COMM_STATE_VALUE
```
And `is_itdma`:
```python
    @property
    def is_itdma(self) -> bool:
        if isinstance(self, (MessageType1, MessageType2)):
            return False
        if isinstance(self, (MessageType3, MessageType4, MessageType11)):
            return True
        # Fallback for 9, 18, 26 and any others
        return self.radio > self.MAX_COMM_STATE_VALUE
```
Wait, `is_itdma` is just `not is_sotdma`.

But wait, what if `self` is not any of these? The `CommunicationStateMixin` is only used by these.
Actually, I should check for the classes.

Wait, `MessageType2` and `MessageType3` inherit from `MessageType1`.
So `isinstance(self, MessageType1)` will be true for `MessageType1`, `MessageType2`, and `MessageType3`.
That's not what I want. I need to distinguish between them.

I can check `self.msg_type`.
`MessageType1` has `msg_type = 1`.
`MessageType2` has `msg_type = 2`.
`MessageType3` has `msg_type = 3`.
`MessageType4` has `msg_type = 4`.
`MessageType11` likely has `msg_type = 11`.

Let's check `MessageType11`'s `msg_type`.

Yes, it's 11.

So I can use `self.msg_type` if it exists. But `CommunicationStateMixin` should be generic.
Wait, the classes are already there. I can just use `type(self)`.

Wait, `MessageType1` and `MessageType2` are both SOTDMA. `MessageType3` is ITDMA.
If I use `isinstance(self, MessageType1)`, it will be true for all three.
So I should check for `MessageType3` specifically first?
Or just use the `msg_type` attribute.

Wait, does every class that uses `CommunicationStateMixin` have a `msg_type` attribute?
Yes, they all seem to.

Let's see:
MessageType1: 1
MessageType2: 2
MessageType3: 3
MessageType4: 4
MessageType9: 9
MessageType11: 11
MessageType18: 18
MessageType26: 26

Actually, I can just use a set of SOTDMA types and a set of ITDMA types.
SOTDMA: {1, 2}
ITDMA: {3, 4, 11}
Fallback: {9, 18, 26}

Wait, what if there are other types?
The problem says: "Type 9, 18 and 26 messages are edge cases... The existing implementation can be used here".

So:
```python
    @property
    def is_sotdma(self) -> bool:
        if getattr(self, 'msg_type', None) in (1, 2):
            return True

            return False
        return self.radio <= self.MAX_COMM_STATE_VALUE
