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 XKNX/xknx.

Problem Statement:
2.6.0 filters telegrams from KNX gateway/tunnel device itself
**Description of problem:**

Since xknx 2.6.0, xknx no longer recieves/processes telegrams originating from the KNX gateway itself.
A RTU modbus device is connected directly to the gateway, which is why the packets originates from the gateway itself (address 1.1.255)
Other telegrams from the KNX/TP bus are received fine through the gateway.

- [X] using xknx standalone
- [X] using Home-Assistant knx integration

**Version information:**
- xknx / Home-Assistant release with the issue: xknx 2.6.0
- last working xknx / Home-Assistant release (if known): xknx 2.5.0

**KNX installation:**
Using a SE SpaceLYnk gateway, with a modbus based power meter connected. The gateway exposes the modbus data via KNX address 1/1/4 as a 4byte_float.
Other devices connected to the gateway over KNX/TP are unaffected by the update to 2.6.0 and still work.

Using https://github.com/XKNX/xknx/blob/main/examples/example_telegram_monitor.py to compare the versons.
With 2.5.0 i see telegrams from the modbus device, on 2.6.0 i don't.

Adding debug logging to the same script shows the frames being recieved, but ignored on 2.6.0:
`DEBUG:xknx.cemi:Ignoring own CEMI: <CEMIFrame code="L_DATA_IND" src_addr="IndividualAddress("1.1.255")" dst_addr="GroupAddress("1/1/4")" flags="1011110011100000" tpci="TDataGroup()" payload="<GroupValueWrite value="<DPTArray value="[0xbe,0xa5,0xbb,0xb8]" />" />" />`

This change seems to be related to this commit:
https://github.com/XKNX/xknx/commit/996697ae8cce878aadfcbd95833b1fde3367008a

Is there a reason for these frames now being ignored? Is it possible to roll back this change?

## 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.

```
It seems `xknx` ignores `L_DATA_IND` frames if the source address is equal to `self.xknx.current_address`.
The problem description says:
"A RTU modbus device is connected directly to the gateway, which is why the packets originates from the gateway itself (address 1.1.255)"
In this case, `self.xknx.current_address` is likely `1.1.255`, and since the gateway sends these telegrams from its own address, they are being ignored.

The user mentions that in version 2.5.0 it worked. This suggests that this check was added in 2.6.0 (which matches the commit they linked, although I can't access the link).

If the gateway itself generates telegrams (e.g., from an internal modbus bridge), we should be able to receive them.
However, the comment says: `# L_DATA_IND frames from our own address should be ignored (may occur form routing)`.
This is probably to prevent loops if the gateway echoes back our own sent telegrams.

Wait, if the gateway echoes back our sent telegrams, we probably shouldn't process them as incoming telegrams. But if the gateway *generates* its own telegrams and sends them with its own address, we *should* process them.

How can we distinguish between an echoed telegram and a telegram generated by the gateway?
Usually, if we sent a telegram, we might not want to hear it back.
However, the issue is specifically that gateways (like SE SpaceLYnk) might use their own address for telegrams generated internally.

If we remove this check, would it cause issues for other users?
If the gateway echoes back sent telegrams, `xknx` might see its own sent telegrams as incoming telegrams, which could cause state updates or trigger other logic.

Let's check where `self.xknx.current_address` is set and used.
I'll check `xknx.xknx.XKNX` class.

The offending code is: ```python if (\n cemi.code is CEMIMessageCode.L_DATA_IND\n and cemi.data.src_addr == self.xknx.current_address\n ):\n # L_DATA_IND frames from our own address should be ignored (may occur form routing)\n logger.debug(\"Ignoring own CEMI: %s\", cemi)\n self.xknx.connection_manager.cemi_count_incoming_error += 1\n return ``` It seems `xknx` ignores `L_DATA_IND` frames if the source address is equal to `self.xknx.current_address`. The problem description says: "A RTU modbus device is connected directly to the gateway, which is why the packets originates from the gateway itself (address 1.1.255)" In this case, `self.xknx.current_address` is likely `1.1.255`, and since the gateway sends these telegrams from its own address, they are being ignored. The user mentions that in version 2.5.0 it worked. This suggests that this check was added in 2.6.0 (which matches the commit they linked, although I can't access the link). If the gateway itself generates telegrams (e.g., from an internal modbus bridge), we should be able to receive them. However, the comment says: `# L_DATA_IND frames from our own address should be ignored (may occur form routing)`. This is probably to prevent loops if the gateway echoes back our own sent telegrams. Wait, if the gateway echoes back our sent telegrams, we probably shouldn't process them as incoming telegrams. But if the gateway *generates* its own telegrams and sends them with its own address, we *should* process them. How can we distinguish between an echoed telegram and a telegram generated by the gateway? Usually, if we sent a telegram, we might not want to hear it back. However, the issue is specifically that gateways (like SE SpaceLYnk) might use their own address for telegrams generated internally. If we remove this check, would it cause issues for other users? If the gateway echoes back sent telegrams, `xknx` might see its own sent telegrams as incoming telegrams, which could cause state updates or trigger other logic. Let's check where `self.xknx.current_address` is set and used. I'll check `xknx.xknx.XKNX` class. <channel|><|tool_call>call:read_file{filepath:<|"|>/workspace/xknx/xknx.py<|"|>}<tool_call|><|tool_response>

I see `self.current_address = IndividualAddress(0)` in `XKNX.__init__`.
It probably gets updated when the connection is established.

Let's check `xknx/core/connection_manager.py` or `xknx/io/knxip_interface.py`.
But first, let's create a reproduction test case to confirm the bug.
I need to simulate a `CEMIFrame` with `L_DATA_IND` and `src_addr` equal to `self.xknx.current_address`.

I'll create a reproduction script.

The bug is reproduced. Now I need to decide how to fix it.
The user wants to be able to receive telegrams from the gateway's own address.
If we just remove the check, will we have problems with echoed telegrams?

In KNX IP, if we send a telegram, some gateways might send it back to us.
However, if the gateway is acting as a source (e.g. Modbus bridge), it's generating a telegram that *should* be treated as incoming.

If we remove the check entirely:
```python
        if (\n            cemi.code is CEMIMessageCode.L_DATA_IND\n            and cemi.data.src_addr == self.xknx.current_address\n        ):\n            # L_DATA_IND frames from our own address should be ignored (may occur form routing)\n            logger.debug(\"Ignoring own CEMI: %s\", cemi)\n            self.xknx.connection_manager.cemi_count_incoming_error += 1\n            return
```
We would receive telegrams where `src_addr == current_address`.

The comment says "(may occur form routing)". This usually refers to the fact that if your own device is a KNX router/gateway, it might see its own telegrams coming back.

Is there a way to distinguish between a telegram we sent and a telegram the gateway generated?
In the CEMI layer, we don't have much more information than the `CEMIFrame`.

If the user is using a gateway that leverages its own address for internal devices (like Modbus), then this filter is too aggressive.

The user asks: "Is there a reason for these frames now being ignored? Is it possible to roll back this change?"

If I remove it, I should verify if there are any existing tests that rely on this behavior.
Let's search for tests that check if telegrams from the same address are ignored.

The bug is reproduced. Now I need to decide how to fix it. The user wants to be able to receive telegrams from the gateway's own address. If we just remove the check, will we have problems with echoed telegrams? In KNX IP, if we send a telegram, some gateways might send it back to us. However, if the gateway is acting as a source (e.g. Modbus bridge), it's generating a telegram that *should* be treated as incoming. If we remove the check entirely: ```python if (\n cemi.code is CEMIMessageCode.L_DATA_IND\n and cemi.data.src_addr == self.xknx.current_address\n ):\n # L_DATA_IND frames from our own address should be ignored (may occur form routing)\n logger.debug(\"Ignoring own CEMI: %s\", cemi)\n self.xknx.connection_manager.cemi_count_incoming_error += 1\n return ``` We would receive telegrams where `src_addr == current_address`. The comment says "(may occur form routing)". This usually refers to the fact that if your own device is a KNX router/gateway, it might see its own telegrams coming back. Is there a way to distinguish between a telegram we sent and a telegram the gateway generated? In the CEMI layer, we don't have much more information than the `CEMIFrame`. If the user is using a gateway that leverages its own address for internal devices (like Modbus), then this filter is too aggressive. The user asks: "Is there a reason for these frames now being ignored? Is it possible to roll back this change?" If I remove it, I should verify if there are any existing tests that rely on this behavior. Let's search for tests that check if telegrams from the same address are ignored. <channel|><|tool_call>call:run_command{command:<|"|>grep -rn "current_address" test/<|"|>}<tool_call|><|tool_response>

        mock_telegram_received.assert_not_called()
        assert xknx.connection_manager.cemi_count_incoming_error == 1
```

This test will fail if I remove the check in `cemi_handler.py`.

The question is whether this behavior is generally desired or if it's causing issues for users with specific gateway setups.
The problem describes a common scenario where the gateway itself is the source.

If I remove the check, I'll be breaking `test_incoming_from_self`.
However, the user's case is a legitimate use case.

Wait, is there a way to make this configurable?
The user asks: "Is there a reason for these frames now being ignored? Is it possible to roll back this change?"

If I roll back the change, I should update the test.
But first, let's think if there's any reason to keep this filter.
As the comment says: `# L_DATA_IND frames from our own address should be ignored (may occur form routing)`.
In KNX IP, if you are using a tunnel, you typically don't see your own telegrams unless the gateway echoes them.
If the gateway echoes them, you get a loop if you have logic that reacts to the telegram and sends another one.

But `xknx` is a library. The user of the library should probably decide if they want to filter their own address or not.
However, this filter is buried deep in `CEMIHandler`.

If we remove the filter, we should check if it causes infinite loops in common usage.
Most `xknx` users just register callbacks or use the `telegrams` queue.

If we remove it, the `test_incoming_from_self` needs to be updated to expect the telegram to be received.

Let's see if there's any other place where `current_address` is used to filter.

I'll look at the `CEMIHandler` again.
```python
        if (\n            cemi.code is CEMIMessageCode.L_DATA_IND\n            and cemi.data.src_addr == self.xknx.current_address\n        ):\n            # L_DATA_IND frames from our own address should be ignored (may occur form routing)\n            logger.debug(\"Ignoring own CEMI: %s\", cemi)\n            self.xknx.connection_manager.cemi_count_incoming_error += 1\n            return
```
It only filters `L_DATA_IND` (data indication), which are the incoming telegrams.

If I remove this block, the telegram will proceed to:
```python
        self.xknx.connection_manager.cemi_count_incoming += 1
        telegram = cemi.data.telegram()
        telegram.direction = TelegramDirection.INCOMING
        self.telegram_received(telegram)
```
And then:
```python
    def telegram_received(self, telegram: Telegram) -> None:
        """Forward Telegram to upper layer."""
        if isinstance(telegram.tpci, tpci.TDataGroup):
            self.xknx.telegrams.put_nowait(telegram)
            return
```
And finally it goes into the `telegrams` queue.

If the user's application doesn't send a telegram in response to receiving one with its own address, there is no loop.

The user specifically mentioned that their Modbus device is connected to the gateway and the gateway sends it on behalf of the Modbus device using its own address.

I think the correct fix is to remove this restriction and let the user handle it if they see echoes. Or maybe there's a way to make it an option. But given the request to "roll back this change", removing it is the most direct way.

Wait, should I just remove the `cemi.data.src_addr == self.xknx.current_address` check, or the whole block?
The whole block's purpose is this check.

Let's try to remove it and run the tests.

I'll look at the `CEMIHandler` again. ```python if (\n cemi.code is CEMIMessageCode.L_DATA_IND\n and cemi.data.src_addr == self.xknx.current_address\n ):\n # L_DATA_IND frames from our own address should be ignored (may occur form routing)\n logger.debug(\"Ignoring own CEMI: %s\", cemi)\n self.xknx.connection_manager.cemi_count_incoming_error += 1\n return ``` It only filters `L_DATA_IND` (data indication), which are the incoming telegrams. If I remove this block, the telegram will proceed to: ```python self.xknx.connection_manager.cemi_count_incoming += 1 telegram = cemi.data.telegram() telegram.direction = TelegramDirection.INCOMING self.telegram_received(telegram) ``` And then: ```python def telegram_received(self, telegram: Telegram) -> None: """Forward Telegram to upper layer.""" if isinstance(telegram.tpci, tpci.TDataGroup): self.xknx.telegrams.put_nowait(telegram) return ``` And finally it goes into the `telegrams` queue. If the user's application doesn't send a telegram in response to receiving one with its own address, there is no loop. The user specifically mentioned that their Modbus device is connected to the gateway and the gateway sends it on behalf of the Modbus device using its own address. I think the correct fix is to remove this restriction and let the user handle it if they see echoes. Or maybe there's a way to make it an option. But given the request to "roll back this change", removing it is the most direct way. Wait, should I just remove the `cemi.data.src_addr == self.xknx.current_address` check, or the whole block? The whole block's purpose is this check. Let's try to remove it and run the tests.<channel|><|tool_call>call:edit_file{filepath:<|"|>/workspace/xknx/cemi/cemi_handler.py<|"|>,new_string:<|"|> if cemi.code is CEMIMessageCode.L_DATA_REQ: # L_DATA_REQ frames should only be outgoing. logger.warning("Received unexpected L_DATA_REQ frame: %s", cemi) self.xknx.connection_manager.cemi_count_incoming_error += 1 return logger.debug("Incoming CEMI: %s", cemi) if self.data_secure is not None:<|"|>,old_string:<|"|> if cemi.code is CEMIMessageCode.L_DATA_REQ: # L_DATA_REQ frames should only be outgoing. logger.warning("Received unexpected L_DATA_REQ frame: %s", cemi) self.xknx.connection_manager.cemi_count_incoming_error += 1 return if ( cemi.code is CEMIMessageCode.L_DATA_IND and cemi.data.src_addr == self.xknx.current_address ): # L_DATA_IND frames from our own address should be ignored (may occur form routing) logger.debug("Ignoring own CEMI: %s", cemi) self.xknx.connection_manager.cemi_count_incoming_error += 1 return logger.debug("Incoming CEMI: %s", cemi) if self.data_secure is not None:<|"|>}<tool_call|><|tool_response>
