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` where the `TER:` notation in `CFG.from_text()` is not respected for uppercase terminals.

Example given:
`CFG.from_text('S -> "TER:A"')` should be equivalent to `CFG(variables={"S"}, terminals={"A"}, start_symbol="S", productions={Production(Variable("S"), (Terminal("A"),))})`.

If `TER:` is not respected for uppercase terminals, it might be that the parser is treating `"TER:A"` literally as a terminal with the value `"TER:A"` or something else, instead of just `A`.

Let's start by reproducing this.

Wait, look at the output of `CFG1 productions: {S -> A}`.
And `CFG1 terminals: set()`. This is weird. If it's `S -> A` and `S` is the start symbol, then `A` should be a terminal if it's in quotes in `from_text`.

Wait, in `CFG.from_text('S -> "TER:A"')`, `"TER:A"` is in quotes.
According to `pyformlang` documentation (which I don't have here, but can infer), quotes usually denote terminals.

Wait, if `CFG1 productions: {S -> A}`, and `CFG1 terminals: set()`, it means `A` might be treated as a variable?
Wait, if `A` is uppercase, maybe it's being treated as a variable by default?
But it's inside quotes!

Let's look at the `CFG.from_text` implementation.
It's probably in `pyformlang/cfg/cfg.py`.

Look at `_read_line` method:

```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))
```

And `is_special_text`:
```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] == '"'
```

Now let's trace `body_component = '"TER:A"'`.
1. `is_special_text('"TER:A"')` returns `True`.
2. `type_component = body_component[1:4]` -> `"TER"`.
3. `body_component = body_component[5:-1]` -> `"A"`.
4. Next: `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 `if` block and creates a `Variable("A")`.

Wait! If `type_component == "TER"`, it should definitively be a `Terminal`, regardless of whether it starts with an uppercase letter.

The logic currently is:
```python
                if body_component[0] in string.ascii_uppercase or \
                        type_component == "VAR":
                    body_var = Variable(body_component)
```

It should be:
If `type_component == "VAR"`, it's a variable.
Else if `type_component == "TER"`, it's a terminal.
Else if `body_component[0]` is uppercase, it's a variable.
Else if it's not an epsilon symbol, it's a terminal.

Wait, the current code prioritize `body_component[0] in string.ascii_uppercase` OVER `type_component == "TER"`.

Let's rewrite the if-elif logic.

Correct logic should be:
1. If `type_component == "VAR"`, it's a `Variable`.
2. If `type_component == "TER"`, it's a `Terminal`.
3. If `type_component == ""`:
    a. If `body_component[0] in string.ascii_uppercase`, it's a `Variable`.
    b. If `body_component` is in `EPSILON_SYMBOLS`, it's epsilon.
    c. Otherwise, it's a `Terminal`.

Looking at the current code:
```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"` and `body_component` starts with uppercase, it goes into the first `if` and becomes a `Variable`. This is exactly the bug.

Also, let's check the `elif` condition: `elif body_component not in EPSILON_SYMBOLS or type_component == "TER":`.
If `body_component` is in `EPSILON_SYMBOLS` but `type_component == "TER"`, it becomes a `Terminal`. This seems correct (if you explicitly mark epsilon as a terminal).

But the main issue is that the first `if` is too broad. It should only be `Variable` if (`type_component == "VAR"`) OR (`type_component == ""` AND `body_component[0]` is uppercase).

Wait, if `type_component == "TER"`, it MUST be a terminal.

Let's refine the 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)
```

Is this exhaustive?
- `type_component == "VAR"` -> Variable.
- `type_component == "TER"` -> Terminal.
- `type_component == ""` and uppercase -> Variable.
- `type_component == ""` and not uppercase and not epsilon -> Terminal.
- `type_component == ""` and epsilon -> Nothing added to body. (This is correct for epsilon).

Let's check if there are other cases.
What if `type_component == ""` and it's in `EPSILON_SYMBOLS`?
The current code:
```python
                if body_component[0] in string.ascii_uppercase or \
                        type_component == "VAR":
                    # ...
                elif body_component not in EPSILON_SYMBOLS or type_component \
                        == "TER":
                    # ...
```
If `body_component` is `"epsilon"` (in `EPSILON_SYMBOLS`) and `type_component == ""`:
- First `if`: `"epsilon"[0]` is `'e'`, not uppercase. `type_component` is `""`. So `False`.
- `elif`: `"epsilon" not in EPSILON_SYMBOLS` is `False`. `type_component == "TER"` is `False`. So `False`.
Nothing is added. Correct.

If `body_component` is `"epsilon"` and `type_component == "TER"`:
- First `if`: `'e'` not uppercase, `type_component` not `"VAR"`. `False`.
- `elif`: `"epsilon" not in EPSILON_SYMBOLS` is `False`. `type_component == "TER"` is `True`. `True`.
It becomes a `Terminal("epsilon")`. Correct.

So my proposed 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, let's check the `body_component` indexing. `body_component` could be empty?
`sub_body.split()` will not produce empty strings.
What if `body_component` is empty?
`body_component[0]` would raise `IndexError`.
But `body_component` comes from `sub_body.split()`, so it has at least one character.

Let's double check the logic again.
If `type_component == "VAR"`, first `if` is `True`. -> Variable. Correct.
If `type_component == "TER"`, first `if` is `False` (since `type_component` is not `"VAR"` and it's not `""`). Second `if` (`elif`) is `True`. -> Terminal. Correct.
If `type_component == ""`:
- `body_component[0]` is uppercase -> First `if` is `True`. -> Variable. Correct.
- `body_component` is epsilon -> First `if` is `False`. Second `if` is `False`. -> Nothing. Correct.
- `body_component` is not uppercase and not epsilon -> First `if` is `False`. Second `if` is `True`. -> Terminal. Correct.

This looks solid.

Let's check if there are any other places where `TER:` or `VAR:` notation is used.
The search `grep -rn "is_special_text" .` might be useful.

Wait, `FCFG` is a subclass of `CFG`. Why does it have its own `_read_line`? Because it needs to handle feature structures.

So I should apply the fix in both `pyformlang/cfg/cfg.py` and `pyformlang/fcfg/fcfg.py`.

Let's verify the reproduction script again, and maybe add a case that tests `VAR:` for non-uppercase.

I'm having a brain fart. The parameters are `filepath`, `old_string`, `new_string`.

Let me just use `run_command` with `sed` or something if I keep failing at `edit_file`. No, I can do this.

The reason it might be failing is because I am putting the `old_string` in the `if` parameter position.

Wait, I see what I did. I put it in the `if` parameter of the tool call. There is no `if` parameter in `edit_file`.

Correct: `edit_file(filepath=..., old_string=..., new_string=...)`

Let me check the `edit_file` declaration:
`edit_file(filepath, old_string, new_string, allow_multiple=False)`

Ah, I see. I was using it like:
`edit_file(filepath=..., if ..., new_string=..., old_string=...)`

Wait, no, I just saw what happened. I was literally writing `if ...` instead of `old_string=...`.

I don't understand why it says `old_string` is missing.

I'll try using positional arguments if it's easier, but the tool definition says `filepath`, `old_string`, `new_string` are required.

Wait, I am using a tool a lot. Let me look at the tool call I just sent:
`edit_file{filepath: "pyformlang/cfg/cfg.py", if body_component[0] ..., new_string: ..., old_string: ...}`

Ah! I am putting a random string before `new_string` that is not a parameter name.

```json
{
  "filepath": "pyformlang/cfg/cfg.py",
  "if body_component[0] in string.ascii_uppercase or \\\n                        type_component == \"VAR\":": "body_var = Variable(body_component)\n                    variables.add(body_var)\n                    body.append(body_var)\n                elif body_component not in EPSILON_SYMBOLS or type_component \\\n                        == \"TER\":\n                    body_ter = Terminal(body_component)\n                    terminals.add(body_ter)\n                    body.append(body_ter)",

Wait, if I look at my previous call:

I see what's happening. I am not using `old_string=` prefix for the first argument. The tool call expects `old_string` and `new_string` as keywords.

Let me look at my call again:
`edit_file{filepath: "pyformlang/cfg/cfg.py", if body_component[0] ..., new_string: ..., old_string: ...}`

I am putting the old string as a value to a key named `if body_component[0]...`.

I MUST use `old_string=...`.

Let me try again.

I see what's happening. I am not using `old_string=` prefix for the first argument. The tool call expects `old_string` and `new_string` as keywords. Let me look at my call again: `edit_file{filepath: "pyformlang/cfg/cfg.py", if body_component[0] ..., new_string: ..., old_string: ...}` I am putting the old string as a value to a key named `if body_component[0]...`. I MUST use `old_string=...`. Let me try again. <channel|><|tool_call>call:edit_file{filepath:<|"|>pyformlang/cfg/cfg.py<|"|>,if body_component[0] in string.ascii_uppercase or \\\ type_component == "VAR":<|"|>\n body_var = Variable(body_component)\n variables.add(body_var)\n body.append(body_var)\n elif body_component not in EPSILON_SYMBOLS or type_component \\\n == "TER":\n body_ter = Terminal(body_component)\n terminals.add(body_ter)\n body.append(body_ter)`<|"|>,new_string:<|"|> if type_component == "VAR" or \\\ (type_component == "" and body_component[0] in string.ascii_uppercase):\n body_var = Variable(body_component)\n variables.add(body_var)\n body.append(body_var)\n elif type_component == "TER" or \\\ (type_component == "" and body_component not in EPSILON_SYMBOLS):\n body_ter = Terminal(body_component)\n terminals.add(body_ter)\n body.append(body_ter)`,old_string:<|"|>}<tool_call|><|tool_response>
