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 prompt 5,815 characters

You are evaluating a software engineering task for repository Aunsiels/pyformlang.

Problem Statement:
TER:X notation is not respected for uppercase terminals in CFGs
**Describe the bug**
Consider the difference between the following two CFGs. According to the `from_text` documentation, they should be equivalent.

```
from pyformlang.cfg import CFG, Production, Terminal, Variable

cfg = CFG.from_text('S -> "TER:A"')
print(cfg.is_empty())
print(cfg.productions)

print("vs")
# vs
cfg = CFG(
    variables={"S"},
    terminals={"A"},
    start_symbol="S",
    productions={Production(Variable("S"), (Terminal("A"),))},
)
print(cfg.is_empty())
print(cfg.productions)
```

**Expected behavior**
Generating the second CFG when parsing the first text.

## 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 a bug in `pyformlang.cfg.CFG.from_text`.
The issue is that `TER:X` notation for uppercase terminals in CFGs is not respected.
In the provided example:
`CFG.from_text('S -> "TER:A"')` should be equivalent to:
`CFG(variables={"S"}, terminals={"A"}, start_symbol="S", productions={Production(Variable("S"), (Terminal("A"),))})`.

Wait, the "TER:" notation is a way to specify that a terminal is being used, even if it looks like a variable (e.g., starts with an uppercase letter).

Let's reproduce this first.

Wait, the output shows:

`cfg2 productions: {S -> Terminal(A)}`

Wait, if `S` is a Variable and `A` is a Terminal, then `S -> Terminal(A)` is what we expect.
But `cfg1.productions` says `{S -> A}`.
Wait, let's look closer at what `CFG.from_text` produced.

If `cfg1 = CFG.from_text('S -> "TER:A"')`, and `cfg1.productions` is `{S -> A}`, does that `A` represent a Variable or a Terminal?

Let's check the types of the symbols in `cfg1`.

Confirmed. `CFG.from_text('S -> "TER:A"')` resulted in a production where the body is a `Variable` instead of a `Terminal`.

Confirmed. `CFG.from_text('S -> "TER:A"')` resulted in a production where the body is a `Variable` instead of a `Terminal`. Now let's find where `from_text` is implemented.

Let's look at `_read_line`:

```python
    @classmethod
    def _read_line(cls, line, productions, terminals, variables):
        head_s, body_s = line.split("->")
        head_text = head_s.strip()
        if is_special_text(head_text):
            head_text = head_text[5:-1]
        head = Variable(head_text)
        variables.add(head)
        for sub_body in body_s.split("|"):
            body = []
            for body_component in sub_body.split():
                if is_special_text(body_component):
                    type_component = body_component[1:4]
                    body_component = body_component[5:-1]
                else:
                    type_component = ""
                if body_component[0] in string.ascii_uppercase or \
                        type_component == "VAR":
                    body_var = Variable(body_component)
                    variables.add(body_var)
                    body.append(body_var)
                elif body_component not in EPSILON_SYMBOLS or type_component \
                        == "TER":
                    body_ter = Terminal(body_component)
                    terminals.add(body_ter)
                    body.append(body_ter)
            productions.add(Production(head, body))
```

Wait, look at this part:

```python
                if body_component[0] in string.ascii_uppercase or \
                        type_component == "VAR":
                    body_var = Variable(body_component)
                    variables.add(body_var)
                    body.append(body_var)
                elif body_component not in EPSILON_SYMBOLS or type_component \
                        == "TER":
                    body_ter = Terminal(body_component)
                    terminals.add(body_ter)
                    body.append(body_ter)
```

If `body_component` is `"TER:A"`, then:
1. `is_special_text('"TER:A"')` is True.
2. `type_component` becomes `"TER"` (from `body_component[1:4]`, since `body_component` is `"TER:A"`? Wait, no, `body_component` was `"TER:A"`? No, `body_component` in the original line were `"TER:A"` with quotes).

Let's trace `"TER:A"` (with quotes):
- `body_component` = `"TER:A"`
- `is_special_text('"TER:A"')` is True.
- `type_component = body_component[1:4]` -> `body_component` is `"TER:A"`. Indices: 0 is `"`, 1 is `T`, 2 is `E`, 3 is `R`. So `type_component` is `"TER"`.
- `body_component = body_component[5:-1]` -> `body_component` becomes `A`.
- Now it checks: `if body_component[0] in string.ascii_uppercase or type_component == "VAR":`
- `body_component[0]` is `A`, which is in `string.ascii_uppercase`.
- So it enters the first block and creates a `Variable(A)`.

This is exactly the bug! It gives priority to the uppercase check over the `type_component == "TER"` check.

It should check `type_component == "VAR"` and `type_component == "TER"` first, or adjust the logic so that if `type_component` is `"TER"`, it's always a terminal regardless of whether the first letter is uppercase.

If `type_component` is not empty, it should probably decide based on `type_component`.

If `type_component == "VAR"`, it's a Variable.
If `type_component == "TER"`, it's a Terminal.
If `type_component == ""`, then use the first-letter rule.

Let's refine the logic:

```python
                if type_component == "VAR":
                    body_var = Variable(body_component)
                    variables.add(body_var)
                    body.append(body_var)
                elif type_component == "TER":
                    body_ter = Terminal(body_component)
                    terminals.add(body_ter)
                    body.append(body_ter)
                elif body_component[0] in string.ascii_uppercase:
                    body_var = Variable(body_component)
                    variables.add(body_var)
                    body.append(body_var)
                elif body_component not in EPSILON_SYMBOLS:
                    body_ter = Terminal(body_component)
                    terminals.add(body_ter)
                    body.append(body_ter)
                elif type_component == "TER": # This is already covered
                    pass
```

Wait, let's see the original logic again.

```python
                if body_component[0] in string.ascii_uppercase or \
                        type_component == "VAR":
                    body_var = Variable(body_component)
                    variables.add(body_var)
                    body.append(body_var)
                elif body_component not in EPSILON_SYMBOLS or type_component \
                        == "TER":
                    body_ter = Terminal(body_component)
                    terminals.add(body_ter)
                    body.append(body_ter)
```

If `type_component == "TER"`, it should be a Terminal.
If `type_component == "VAR"`, it should be a Variable.
If `type_component == ""`, it should depend on `body_component[0]`.

So the logic should be:

```python
                if type_component == "VAR" or (type_component == "" and body_component[0] in string.ascii_uppercase):
                    body_var = Variable(body_component)
                    variables.add(body_var)
                    body.append(body_var)
                elif type_component == "TER" or (type_component == "" and body_component not in EPSILON_SYMBOLS):
                    body_ter = Terminal(body_component)
                    terminals.add(body_ter)
                    body.append(body_ter)
```
Wait, what if it's in `EPSILON_SYMBOLS`?
Original code:
`elif body_component not in EPSILON_SYMBOLS or type_component == "TER":`
If `body_component` is in `EPSILON_SYMBOLS`, it's not added to `body` unless `type_component == "TER"`.

Let's double check: if `body_component` is `"epsilon"`, and `type_component == ""`, then `body_component not in EPSILON_SYMBOLS` is False, so it's not added. This is correct as epsilons are handled (by NOT being added to the body, the production becomes an epsilon production).

If `body_component` is `"epsilon"`, but `type_component == "TER"`, then `type_component == "TER"` is True, so it's added as a Terminal. This is also correct.

So the updated logic:
```python
                if type_component == "VAR" or (type_component == "" and body_component[0] in string.ascii_uppercase):
                    body_var = Variable(body_component)
                    variables.add(body_var)
                    body.append(body_var)
                elif type_component == "TER" or (type_component == "" and body_component not in EPSILON_SYMBOLS):
                    body_ter = Terminal(body_component)
                    terminals.add(body_ter)
                    body.append(body_ter)
```
Wait, I should be careful about `body_component` being empty. But `sub_body.split()` won't give empty strings.

Let's check the original code again.
`if body_component[0] in string.ascii_uppercase or type_component == "VAR":`
If `type_component == "TER"` and `body_component[0]` is uppercase, it goes here. This is the bug.

If I change it to:
```python
                if type_component == "VAR" or (type_component == "" and body_component[0] in string.ascii_uppercase):
                    # ...
                elif type_component == "TER" or (type_component == "" and body_component not in EPSILON_SYMBOLS):
                    # ...
```
This should fix it.

Let's verify with a few more cases.
Case 1: `"TER:A"` -> `type_component="TER"`, `body_component="A"`.
- `type_component == "VAR"` is False.
- `type_component == ""` is False.
- Result: goes to `elif`.
- `type_component == "TER"` is True.
- Result: `Terminal("A")`. CORRECT.

Case 2: `"VAR:a"` -> `type_component="VAR"`, `body_component="a"`.
- `type_component == "VAR"` is True.
- Result: `Variable("a")`. CORRECT.

Case 3: `"a"` -> `type_component=""`, `body_component="a"`.
- `type_component == "VAR"` is False.
- `type_component == ""` is True AND `body_component[0]` ('a') is not uppercase.
- Result: goes to `elif`.
- `type_component == "TER"` is False.
- `type_component == ""` is True AND `"a"` not in `EPSILON_SYMBOLS`.
- Result: `Terminal("a")`. CORRECT.

Case 4: `"A"` -> `type_component=""`, `body_component="A"`.
- `type_component == "VAR"` is False.
- `type_component == ""` is True AND `body_component[0]` ('A') is uppercase.
- Result: `Variable("A")`. CORRECT.

Case 5: `"epsilon"` -> `type_component=""`, `body_component="epsilon"`.
- `type_component == "VAR"` is False.
- `type_component == ""` is True AND `body_component[0]` ('e') is not uppercase.
- Result: goes to `elif`.
- `type_component == "TER"` is False.
- `type_component == ""` is True AND `"epsilon"` not in `EPSILON_SYMBOLS` is False.
- Result: nothing added. CORRECT.

Case 6: `"TER:epsilon"` -> `type_component="TER"`, `body_component="epsilon"`.
- `type_component == "VAR"` is False.
- `type_component == ""` is False.
- Result: goes to `elif`.
- `type_component == "TER"` is True.
- Result: `Terminal("epsilon")`. CORRECT.

So the proposed fix seems correct.

Let's apply it. I'll use `edit_file`.

Wait, I should check if there are other places where `is_special_text` or `type_component` is used.
In `_read_line`, it's used for `head_text` and `body_component`.

For `head_text`:
```python
        head_text = head_s.strip()
        if is_special_text(head_text):
            head_text = head_text[5:-1]
        head = Variable(head_text)
        variables.add(head)
```
Here it only supports `Variable` for the head, so `VAR:` or `TER:` (if used for the head) both result in `Variable(head_text)`. That's probably fine since the head of a production in a CFG must be a variable.

Let's check `is_special_text` implementation:
```python
def is_special_text(text):
    """ Check if the input is given an explicit type """
    return len(text) > 5 and \
        (text[0:5] == '"VAR:' or text[0:5] == '"TER:') and \
        text[-1] == '"'
```
It's simple and works as expected.

Now I will apply the fix to `pyformlang/cfg/cfg.py`.

Let's look at `_read_line`: ```python @classmethod def _read_line(cls, line, productions, terminals, variables): head_s, body_s = line.split("->") head_text = head_s.strip() if is_special_text(head_text): head_text = head_text[5:-1] head = Variable(head_text) variables.add(head) for sub_body in body_s.split("|"): body = [] for body_component in sub_body.split(): if is_special_text(body_component): type_component = body_component[1:4] body_component = body_component[5:-1] else: type_component = "" if body_component[0] in string.ascii_uppercase or \ type_component == "VAR": body_var = Variable(body_component) variables.add(body_var) body.append(body_var) elif body_component not in EPSILON_SYMBOLS or type_component \ == "TER": body_ter = Terminal(body_component) terminals.add(body_ter) body.append(body_ter) productions.add(Production(head, body)) ``` Wait, look at this part: ```python if body_component[0] in string.ascii_uppercase or \ type_component == "VAR": body_var = Variable(body_component) variables.add(body_var) body.append(body_var) elif body_component not in EPSILON_SYMBOLS or type_component \ == "TER": body_ter = Terminal(body_component) terminals.add(body_ter) body.append(body_ter) ``` If `body_component` is `"TER:A"`, then: 1. `is_special_text('"TER:A"')` is True. 2. `type_component` becomes `"TER"` (from `body_component[1:4]`, since `body_component` is `"TER:A"`? Wait, no, `body_component` was `"TER:A"`? No, `body_component` in the original line were `"TER:A"` with quotes). Let's trace `"TER:A"` (with quotes): - `body_component` = `"TER:A"` - `is_special_text('"TER:A"')` is True. - `type_component = body_component[1:4]` -> `body_component` is `"TER:A"`. Indices: 0 is `"`, 1 is `T`, 2 is `E`, 3 is `R`. So `type_component` is `"TER"`. - `body_component = body_component[5:-1]` -> `body_component` becomes `A`. - Now it checks: `if body_component[0] in string.ascii_uppercase or type_component == "VAR":` - `body_component[0]` is `A`, which is in `string.ascii_uppercase`. - So it enters the first block and creates a `Variable(A)`. This is exactly the bug! It gives priority to the uppercase check over the `type_component == "TER"` check. It should check `type_component == "VAR"` and `type_component == "TER"` first, or adjust the logic so that if `type_component` is `"TER"`, it's always a terminal regardless of whether the first letter is uppercase. If `type_component` is not empty, it should probably decide based on `type_component`. If `type_component == "VAR"`, it's a Variable. If `type_component == "TER"`, it's a Terminal. If `type_component == ""`, then use the first-letter rule. Let's refine the logic: ```python if type_component == "VAR": body_var = Variable(body_component) variables.add(body_var) body.append(body_var) elif type_component == "TER": body_ter = Terminal(body_component) terminals.add(body_ter) body.append(body_ter) elif body_component[0] in string.ascii_uppercase: body_var = Variable(body_component) variables.add(body_var) body.append(body_var) elif body_component not in EPSILON_SYMBOLS: body_ter = Terminal(body_component) terminals.add(body_ter) body.append(body_ter) elif type_component == "TER": # This is already covered pass ``` Wait, let's see the original logic again. ```python if body_component[0] in string.ascii_uppercase or \ type_component == "VAR": body_var = Variable(body_component) variables.add(body_var) body.append(body_var) elif body_component not in EPSILON_SYMBOLS or type_component \ == "TER": body_ter = Terminal(body_component) terminals.add(body_ter) body.append(body_ter) ``` If `type_component == "TER"`, it should be a Terminal. If `type_component == "VAR"`, it should be a Variable. If `type_component == ""`, it should depend on `body_component[0]`. So the logic should be: ```python if type_component == "VAR" or (type_component == "" and body_component[0] in string.ascii_uppercase): body_var = Variable(body_component) variables.add(body_var) body.append(body_var) elif type_component == "TER" or (type_component == "" and body_component not in EPSILON_SYMBOLS): body_ter = Terminal(body_component) terminals.add(body_ter) body.append(body_ter) ``` Wait, what if it's in `EPSILON_SYMBOLS`? Original code: `elif body_component not in EPSILON_SYMBOLS or type_component == "TER":` If `body_component` is in `EPSILON_SYMBOLS`, it's not added to `body` unless `type_component == "TER"`. Let's double check: if `body_component` is `"epsilon"`, and `type_component == ""`, then `body_component not in EPSILON_SYMBOLS` is False, so it's not added. This is correct as epsilons are handled (by NOT being added to the body, the production becomes an epsilon production). If `body_component` is `"epsilon"`, but `type_component == "TER"`, then `type_component == "TER"` is True, so it's added as a Terminal. This is also correct. So the updated logic: ```python if type_component == "VAR" or (type_component == "" and body_component[0] in string.ascii_uppercase): body_var = Variable(body_component) variables.add(body_var) body.append(body_var) elif type_component == "TER" or (type_component == "" and body_component not in EPSILON_SYMBOLS): body_ter = Terminal(body_component) terminals.add(body_ter) body.append(body_ter) ``` Wait, I should be careful about `body_component` being empty. But `sub_body.split()` won't give empty strings. Let's check the original code again. `if body_component[0] in string.ascii_uppercase or type_component == "VAR":` If `type_component == "TER"` and `body_component[0]` is uppercase, it goes here. This is the bug. If I change it to: ```python if type_component == "VAR" or (type_component == "" and body_component[0] in string.ascii_uppercase): # ... elif type_component == "TER" or (type_component == "" and body_component not in EPSILON_SYMBOLS): # ... ``` This should fix it. Let's verify with a few more cases. Case 1: `"TER:A"` -> `type_component="TER"`, `body_component="A"`. - `type_component == "VAR"` is False. - `type_component == ""` is False. - Result: goes to `elif`. - `type_component == "TER"` is True. - Result: `Terminal("A")`. CORRECT. Case 2: `"VAR:a"` -> `type_component="VAR"`, `body_component="a"`. - `type_component == "VAR"` is True. - Result: `Variable("a")`. CORRECT. Case 3: `"a"` -> `type_component=""`, `body_component="a"`. - `type_component == "VAR"` is False. - `type_component == ""` is True AND `body_component[0]` ('a') is not uppercase. - Result: goes to `elif`. - `type_component == "TER"` is False. - `type_component == ""` is True AND `"a"` not in `EPSILON_SYMBOLS`. - Result: `Terminal("a")`. CORRECT. Case 4: `"A"` -> `type_component=""`, `body_component="A"`. - `type_component == "VAR"` is False. - `type_component == ""` is True AND `body_component[0]` ('A') is uppercase. - Result: `Variable("A")`. CORRECT. Case 5: `"epsilon"` -> `type_component=""`, `body_component="epsilon"`. - `type_component == "VAR"` is False. - `type_component == ""` is True AND `body_component[0]` ('e') is not uppercase. - Result: goes to `elif`. - `type_component == "TER"` is False. - `type_component == ""` is True AND `"epsilon"` not in `EPSILON_SYMBOLS` is False. - Result: nothing added. CORRECT. Case 6: `"TER:epsilon"` -> `type_component="TER"`, `body_component="epsilon"`. - `type_component == "VAR"` is False. - `type_component == ""` is False. - Result: goes to `elif`. - `type_component == "TER"` is True. - Result: `Terminal("epsilon")`. CORRECT. So the proposed fix seems correct. Let's apply it. I'll use `edit_file`. Wait, I should check if there are other places where `is_special_text` or `type_component` is used.

`cfg1 productions: {S -> Terminal(A)}`

Let's check why they are not equal.

Wait, `cfg1 start_symbol: S` and `cfg2 start_symbol: S`.
But are they the same object type?

In `cfg1 = CFG.from_text('S -> "TER:A"')`, `start_symbol` is passed as the default `Variable("S")` to `CFG(...)`.
In `cfg2`, `start_symbol="S"`.

Wait, `CFG.__init__` does:
```python
        if start_symbol is not None:
            start_symbol = to_variable(start_symbol)
        self._start_symbol = start_symbol
```
And `to_variable` likely returns a `Variable` object.

Let's check `pyformlang/cfg/utils.py` for `to_variable`.

It might not have `__eq__`, so it's using the default object equality (identity).

Wait, if I'm comparing two `CFG` objects, and they don't have `__eq__`, they won't be equal unless they are the same object.
