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.

Problem Statement:
`Target.has_calibration` errors for instructions without properties
### Environment

- **Qiskit version**: 1.1.0
- **Python version**: 3.12
- **Operating system**: Fedora Linux 40


### What is happening?

If a `Target` has an `Instruction` with `None` for its `InstructionProperties`, `Target.has_calibration` raises an `AttributeError`.

### How can we reproduce the issue?

Consider this case from the `Target` docstring with the `has_calibration` call added at the end:

```python
from qiskit.circuit.library import CXGate
from qiskit.transpiler import Target, InstructionProperties

target = Target()
cx_properties = {
    (0, 1): None,
    (1, 0): None,
    (0, 2): None,
    (2, 0): None,
    (0, 3): None,
    (2, 3): None,
    (3, 0): None,
    (3, 2): None
}
target.add_instruction(CXGate(), cx_properties)

target.has_calibration("cx", (0, 1))  # AttributeError!
```

### What should happen?

The last line above should return `False`

### Any suggestions?

I will submit a PR.

## 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.

Okay, the `Target` class is in `qiskit/transpiler/target.py`. Let's examine `Target.has_calibration` and `Target.add_instruction` in that file.

  "content": "class Target(Mapping):\n    \"\"\"\n    The intent of the ``Target`` object is to inform Qiskit's compiler about\n    the constraints of a particular backend so the compiler can compile an\n    input circuit to something that works and is optimized for a device. It\n    currently contains a description of instructions on a backend and their\n    properties as well as some timing information. However, this exact\n    interface may evolve over time as the needs of the compiler change. These\n    changes will be done in a backwards compatible and controlled manner when\n    they are made (either through versioning, subclassing, or mixins) to add\n    on to the set of information exposed by a target.\n\n    As a basic example, let's assume backend has two qubits, supports\n    :class:`~qiskit.circuit.library.UGate` on both qubits and\n    :class:`~qiskit.circuit.library.CXGate` in both directions. To model this\n    you would create the target like::\n\n        from qiskit.transpiler import Target, InstructionProperties\n        from qiskit.circuit.library import UGate, CXGate\n        from qiskit.circuit import Parameter\n\n        gmap = Target()\n        theta = Parameter('theta')\n        phi = Parameter('phi')\n        lam = Parameter('lambda')\n        u_props = {\n            (0,): InstructionProperties(duration=5.23e-8, error=0.00038115),\n            (1,): InstructionProperties(duration=4.52e-8, error=0.00032115),\n        }\n        gmap.add_instruction(UGate(theta, phi, lam), u_props)\n        cx_props = {\n            (0,1): InstructionProperties(duration=5.23e-7, error=0.00098115),\n            (1,0): InstructionProperties(duration=4.52e-7, error=0.00132115),\n        }\n        gmap.add_instruction(CXGate(), cx_props)\n\n    Each instruction in the ``Target`` is indexed by a unique string name that uniquely\n    identifies that instance of an :class:`~qiskit.circuit.Instruction` object in\n    the Target. There is a 1:1 mapping between a name and an\n    :class:`~qiskit.circuit.Instruction` instance in the target and each name must\n    be unique. By default, the name is the :attr:`~qiskit.circuit.Instruction.name`\n    attribute of the instruction, but can be set to anything. This lets a single\n    target have multiple instances of the same instruction class with different\n    parameters. For example, if a backend target has two instances of an\n    :class:`~qiskit.circuit.library.RXGate` one is parameterized over any theta\n    while the other is tuned up for a theta of pi/6 you can add these by doing something\n    like::\n\n        import math\n\n        from qiskit.transpiler import Target, InstructionProperties\n        from qiskit.circuit.library import RXGate\n        from qiskit.circuit import Parameter\n\n        target = Target()\n        theta = Parameter('theta')\n        rx_props = {\n            (0,): InstructionProperties(duration=5.23e-8, error=0.00038115),\n        }\n        target.add_instruction(RXGate(theta), rx_props)\n        rx_30_props = {\n            (0,): InstructionProperties(duration=1.74e-6, error=.00012)\n        }\n        target.add_instruction(RXGate(math.pi / 6), rx_30_props, name='rx_30')\n\n    Then in the ``target`` object accessing by ``rx_30`` will get the fixed\n    angle :class:`~qiskit.circuit.library.RXGate` while ``rx`` will get the\n    parameterized :class:`~qiskit.circuit.library.RXGate`.\n\n    .. note::\n\n        This class assumes that qubit indices start at 0 and are a contiguous\n        set if you want a submapping the bits will need to be reindexed in\n        a new``Target`` object.\n\n    .. note::\n\n        This class only supports additions of gates, qargs, and qubits.\n        If you need to remove one of these the best option is to iterate over\n        an existing object and create a new subset (or use one of the methods\n        to do this). The object internally caches different views and these\n        would potentially be invalidated by removals.\n    \"\"\"\n\n    __slots__ = (\n        \"num_qubits\",\n        \"_gate_map\",\n        \"_gate_name_map\",\n        \"_qarg_gate_map\",\n        \"description\",\n        \"_coupling_graph\",\n        \"_instruction_durations\",\n        \"_instruction_schedule_map\",\n        \"dt\",\n        \"granularity\",\n        \"min_length\",\n        \"pulse_alignment\",\n        \"acquire_alignment\",\n        \"_non_global_basis\",\n        \"_non_global_strict_basis\",\n        \"qubit_properties\",\n        \"_global_operations\",\n        \"concurrent_measurements\",\n    )\n\n    def __init__(\n        self,\n        description=None,\n        num_qubits=0,\n        dt=None,\n        granularity=1,\n        min_length=1,\n        pulse_alignment=1,\n        acquire_alignment=1,\n        qubit_properties=None,\n        concurrent_measurements=None,\n    ):\n        \"\"\"\n        Create a new ``Target`` object\n\n        Args:\n            description (str): An optional string to describe the Target.\n            num_qubits (int): An optional int to specify the number of qubits\n                the backend target has.

Typically, you will use this to fully populate\n        a ``Target`` before using it in :class:`~qiskit.providers.BackendV2`. For\n        example::\n\n            from qiskit.circuit.library import CXGate\n            from qiskit.transpiler import Target, InstructionProperties\n\n            target = Target()\n            cx_properties = {\n                (0, 1): None,\n                (1, 0): None,\n                (0, 2): None,\n                (2, 0): None,\n                (0, 3): None,\n                (2, 3): None,\n                (3, 0): None,\n                (3, 2): None\n            }\n            target.add_instruction(CXGate(), cx_properties)\n\n        Will add a :class:`~qiskit.circuit.library.CXGate` to the target with no\n        properties (duration, error, etc) with the coupling edge list:\n        ``(0, 1), (1, 0), (0, 2), (2, 0), (0, 3), (2, 3), (3, 0), (3, 2)``. If\n        there are properties available for the instruction you can replace the\n        ``None`` value in the properties dictionary with an\n        :class:`~qiskit.transpiler.InstructionProperties` object. This pattern\n        is repeated for each :class:`~qiskit.circuit.Instruction` the target\n        supports.\n\n        Args:\n            instruction (Union[qiskit.circuit.Instruction, Type[qiskit.circuit.Instruction]]):\n                The operation object to add to the map. If it's parameterized any value\n                of the parameter can be set. Optionally for variable width\n                instructions (such as control flow operations such as :class:`~.ForLoop` or\n                :class:`~MCXGate`) you can specify the class. If the class is specified than the\n                ``name`` argument must be specified. When a class is used the gate is treated as global\n                and not having any properties set.\n            properties (dict): A dictionary of qarg entries to an\n                :class:`~qiskit.transpiler.InstructionProperties` object for that\n                instruction implementation on the backend. Properties are optional\n                for any instruction implementation, if there are no\n                :class:`~qiskit.transpiler.InstructionProperties` available for the\n                backend the value can be None. If there are no constraints on the\n                instruction (as in a noiseless/ideal simulation) this can be set to\n                ``{None, None}`` which will indicate it runs on all qubits (or all\n                available permutations of qubits for multi-qubit gates). The first\n                ``None`` indicates it applies to all qubits and the second ``None``\n                indicates there are no\n                :class:`~qiskit.transpiler.InstructionProperties` for the\n                instruction. By default, if properties is not set it is equivalent to\n                passing ``{None: None}``.\n            name (str): An optional name to use for identifying the instruction. If not\n                specified the :attr:`~qiskit.circuit.Instruction.name` attribute\n                of ``gate`` will be used. All gates in the ``Target`` need unique\n                names. Backends can differentiate between different\n                parameterization of a single gate by providing a unique name for\n                each (e.g. `\"rx30\"`, `\"rx60\", ``\"rx90\"`` similar to the example in the\n                documentation for the :class:`~qiskit.transpiler.Target` class).\n        Raises:\n            AttributeError: If gate is already in map\n            TranspilerError: If an operation class is passed in for ``instruction`` and no name\n                is specified or ``properties`` is set.\n        \"\"\"\n        is_class = inspect.isclass(instruction)\n        if not is_class:\n            instruction_name = name or instruction.name\n        else:",

```python
    def has_calibration(
        self,
        operation_name: str,
        qargs: tuple[int, ...],
    ) -> bool:
        """Return whether the instruction (operation + qubits) defines a calibration.

        Args:

            qargs: The tuple of qubit indices for the instruction.

        Returns:
            Returns ``True`` if the calibration is supported and ``False`` if it isn't.
        """
        qargs = tuple(qargs)
        if operation_name not in self._gate_map:
            return False
        if qargs not in self._gate_map[operation_name]:
            return False
        return getattr(self._gate_map[operation_name][qargs], "_calibration") is not None
```

The line `return getattr(self._gate_map[operation_name][qargs], "_calibration") is not None` is where the problem is. If `self._gate_map[operation_name][qargs]` is `None`, `getattr(None, "_calibration")` will raise `AttributeError`.

In the reproduction case:
```python
cx_properties = {
    (0, 1): None,
    (1, 0): None,
    # ...
}
target.add_instruction(CXGate(), cx_properties)
```
`add_instruction` will set `self._gate_map["cx"][(0, 1)] = None`.
Then `target.has_calibration("cx", (0, 1))` will call `getattr(None, "_calibration")`, resulting in `AttributeError`.

The fix should be to check if `self._gate_map[operation_name][qargs]` is not `None` before calling `getattr`.

Wait, let me verify the reproduction first.

Found it! ```python def has_calibration( self, operation_name: str, qargs: tuple[int, ...], ) -> bool: """Return whether the instruction (operation + qubits) defines a calibration. Args: operation_name: The name of the operation for the instruction. qargs: The tuple of qubit indices for the instruction. Returns: Returns ``True`` if the calibration is supported and ``False`` if it isn't. """ qargs = tuple(qargs) if operation_name not in self._gate_map: return False if qargs not in self._gate_map[operation_name]: return False return getattr(self._gate_map[operation_name][qargs], "_calibration") is not None ``` The line `return getattr(self._gate_map[operation_name][qargs], "_calibration") is not None` is where the problem is. If `self._gate_map[operation_name][qargs]` is `None`, `getattr(None, "_calibration")` will raise `AttributeError`. In the reproduction case: ```python cx_properties = { (0, 1): None, (1, 0): None, # ... } target.add_instruction(CXGate(), cx_properties) ``` `add_instruction` will set `self._gate_map["cx"][(0, 1)] = None`. Then `target.has_calibration("cx", (0, 1))` will call `getattr(None, "_calibration")`, resulting in `AttributeError`. The fix should be to check if `self._gate_map[operation_name][qargs]` is not `None` before calling `getattr`.

It seems `qiskit._accelerate` is a compiled bundle that is missing or not in the path. The environment rules say "All repository and test dependencies are ALREADY pre-installed."

Wait, `qiskit._accelerate` is probably one of those crates/rust extensions. Let me see the workspace layout again.
`./crates/pyext` exists.
Maybe I need to install something or it's already installed in a site-package but my `PYTHONPATH=.` is making it look at `/workspace/qiskit` which is not fully "installed" (missing build artifacts).

Usually, in these environments, I should not be modifying the `qiskit` source if I want to use the installed version, but the task is to fix the source.

If I use `pytest`, it might be configured to find everything correctly. Let's try to create a test file and run it with `pytest`.

It seems the installed `qiskit` is broken if I try to import it while `qiskit` is a directory in the current path. This is a common Python issue when you have a package in the current directory and also installed in site-packages.

Wait, the error is `qiskit/__init__.py:55: in <module> import qiskit._accelerate`.
The `/workspace/qiskit/__init__.py` is being used.

Maybe I can just mock `qiskit._accelerate` if it's not used by the code I'm testing.
But `qiskit/__init__.py` imports it at the top level.

The `sys.modules` trick failed because `qiskit/__init__.py` still tried to access `qiskit._accelerate` which it thought it had already imported.

Actually, let's try to put the mocks *before* importing `qiskit` something, but the problem is that `from qiskit.circuit.library import CXGate` triggers the import of `qiskit/__init__.py`.

Wait, the `sys.modules`entries I set are just `MagicMock()`.
But `qiskit/__init__.py` does:
```python
import qiskit._accelerate
import qiskit._numpy_compat
# ...
sys.modules["qiskit._accelerate.circuit"] = qiskit._accelerate.circuit
```
If `qiskit._accelerate` is already in `sys.modules`, `import qiskit._accelerate` should just use it.

Ah, I see. The error is `AttributeError: partially initialized module 'qiskit' has no attribute '_accelerate'`.
This is because `qiskit` is the package.

Let's try this:
1. Mock `qiskit._accelerate`
2. Mock `qiskit._numpy_compat`
3. Then import.

Actually, if I just want to test `Target`, I can import `Target` directly from `qiskit.transpiler.target` without going through `qiskit/__init__.py` IF I can avoid it. But `qiskit.transpiler.target` might import `qiskit` something.

Let's check `qiskit/transpiler/target.py` imports.

Wait, if I use `python3 -m qiskit.transpiler.target`, it might work.
Or I can just try to run the reproduction script by manipulating `sys.path` to NOT include the current directory, and then adding only what's needed. But `qiskit` is a package.

The `AttributeError` I'm catching is still the circular import one, not the one I'm looking for.
`Caught expected AttributeError: partially initialized module 'qiskit' has no attribute '_accelerate' (most likely due to a circular import)`

This is because when I do `from qiskit.circuit.library import CXGate`, it imports `qiskit/__init__.py`.
And `qiskit/__init__.py` does:
```python
import qiskit._accelerate
import qiskit._numpy_compat
# ...
sys.modules["qiskit._accelerate.circuit"] = qiskit._accelerate.circuit
```
If `sys.modules["qiskit._accelerate"]` is a `MagicMock()`, then `qiskit._accelerate.circuit` will be a `MagicMock()`.
The `AttributeError` must be happening because `qiskit` package (the module) hasn't finished initializing when it tries to access `qiskit._accelerate`.

Wait, `import qiskit._accelerate` should just set `sys.modules['qiskit._accelerate']`.
But in `qiskit/__init__.py`:
```python
import qiskit._accelerate
import qiskit._numpy_compat

# Globally define compiled submodules.
sys.modules["qiskit._accelerate.circuit"] = qiskit._accelerate.circuit
```
If `qiskit` is being imported, `qiskit` is the module.
When it says `qiskit._accelerate.circuit`, it's accessing the `_accelerate` attribute of the `qiskit` module.
Since `qiskit` (the module) is currently being executed (`__init__.py`), it might not have `_accelerate` attached to it yet if the import didn't bind it.

But `import qiskit._accelerate` should bind `_accelerate` to the `qiskit` module.

Wait! I know! I can just mock `qiskit._accelerate` and then ALSO add it to the `qiskit` module once it's created. But I don't have the module object yet.

Let's try to just mock everything and bypass `qiskit/__init__.py` if possible.
But `qiskit.transpiler` is a subpackage of `qiskit`.

If I remove `qiskit/__init__.py`'s problematic lines? No, I can't edit it just for a test.

Wait, I can just use a different approach to reproduce.
I can write a small script that mimics `Target.has_calibration` logic but uses a fake `_gate_map`.

But the goal is to reproduce it using the actual `Target` class.

Let's try to run the reproduction script but instead of `from qiskit...`, we use:
```python
import sys
import os
sys.path.insert(0, os.path.abspath('.'))
```
Wait, I'm already doing that.

What if I just mock `qiskit` itself? No, that's too much.

Let's try to run the reproduction by mocking `qiskit._accelerate` and `qiskit._numpy_compat` and then using a custom `__init__.py` for `qiskit` in a temporary directory? No, too complex.

Actually, let's look at `qiskit/__init__.py` again.
The problem is:
```python
import qiskit._accelerate
import qiskit._numpy_compat

# Globally define compiled submodules.
sys.modules["qiskit._accelerate.circuit"] = qiskit._accelerate.circuit
```
If I mock `qiskit._accelerate` successfully, `import qiskit._accelerate` will just return the mock.
Then `qiskit._accelerate.circuit` should also be a mock.

Why does it say `partially initialized module 'qiskit' has no attribute '_accelerate'`?
Ah! Because `qiskit` is the module being initialized.
When `import qiskit._accelerate` happens, it might not be adding `_accelerate` to the `qiskit` module if `qiskit` is a namespace package or something. But here it's a regular package (it has `__init__.py`).

Wait, if I just mock the `_accelerate` and `_numpy_compat` modules and then NEVER import the top-level `qiskit` module, but instead import the submodules directly?

Let's try:
```python
import sys
from unittest.mock import MagicMock
sys.modules["qiskit._accelerate"] = MagicMock()
sys.modules["qiskit._numpy_compat"] = MagicMock()
# Instead of from qiskit.transpiler import Target
# we can try to import from the file directly if we can.
# But that's hard.
```

Wait, if I use `python3 -m qiskit.transpiler.target`, it will still import `qiskit`.

What if I just comment out the `import qiskit._accelerate` in `qiskit/__init__.py`?
No, that's modifying source.

Let's try this:
```python
import sys
from unittest.mock import MagicMock
mock_q_accel = MagicMock()
sys.modules["qiskit._accelerate"] = mock_q_accel
sys.modules["qiskit._numpy_compat"] = MagicMock()

# Force the 'qiskit' module to have the '_accelerate' attribute
# We can't because 'qiskit' isn't imported yet.
```

Actually, if I do:
```python
import qiskit
qiskit._accelerate = MagicMock()
```
But `import qiskit` will trigger `__init__.py` which will fail.

What if I just use `pytest` but I tell it to ignore certain things? No.

Wait, I have a better idea. I will just apply the fix and then see if the tests pass.
If the tests pass, then the bug was likely fixed.
But I should try to reproduce it first.

Let's try one more time to reproduce it, but this time, I'll mock `qiskit` and its submodules more aggressively.

Actually, let's try to run the reproduction script without imports from `qiskit` and instead using the source code of `Target` if I can't import it. But that's too much.

Wait, the issue is:
`getattr(None, "_calibration")`

If I can just find where that is in `qiskit/transpiler/target.py`, I can just fix it.

Let's find the `has_calibration` method.
