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:
农历日“二十”“三十”中文名称错误
## 发现版本

v3.4.0

## 问题描述

“廿十”、“卅十” 是不正确的用法,因为“廿”、“卅” 本身就是二十、三十的意思了,正确的应该为“二十”、“三十”。


## 代码示例

```python
from borax.calendars.lunardate import LunarDate, TextUtils

print(TextUtils.day_cn(20)) # “廿十”
ld = LunarDate(2020, 10, 20, 0)
print(ld.cn_day) # “廿十”
print(ld.cn_day_calendar) # “廿十”
print(ld.cn_str()) # “廿十”
```

## 建议方案

只需要修改 `TextUtils.day_cn` 逻辑即可,其他函数均是调用该函数。


## 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 `borax.calendars.lunardate.TextUtils.day_cn`.
Specifically, for day 20, it returns "廿十", which is incorrect; it should be "二十".
Similarly, for day 30, it should return "三十" instead of "卅十".
The problem statement says "廿" means 20 and "卅" means 30, so adding "十" to them is redundant and incorrect.

I need to:
1. Locate `borax/calendars/lunardate.py`.
2. Find the `TextUtils.day_cn` method.
3. Reproduce the issue.
4. Fix the logic in `TextUtils.day_cn`.
5. Verify the fix.

Let's start by locating the code and reproducing the issue.

The implementation of `day_cn` is:

```python
    @staticmethod
    def day_cn(day: int) -> str:
        a, b = divmod(day, 10)
        if b == 0:  # 10,20,30
            b = 10
            if a == 1:  # 10
                a = 0
        return TextUtils.TENS[a] + TextUtils.DAYS_CN[b]
```

Wait, let's trace this for `day = 20`:
`a, b = divmod(20, 10)` -> `a = 2, b = 0`.
Since `b == 0`, `b = 10`.
`a` is not 1, so `a` remains 2.
Result: `TextUtils.TENS[2] + TextUtils.DAYS_CN[10]`.
`TextUtils.TENS` = '初十廿卅' -> `TENS[2]` = '廿'.
`TextUtils.DAYS_CN` = '日一二三四五六七八九十' -> `DAYS_CN[10]` = '十'.
Result: '廿十'.

For `day = 30`:
`a, b = divmod(30, 10)` -> `a = 3, b = 0`.
Since `b == 0`, `b = 10`.
`a` is not 1, so `a` remains 3.
Result: `TextUtils.TENS[3] + TextUtils.DAYS_CN[10]`.
`TENS[3]` = '卅'.
`DAYS_CN[10]` = '十'.
Result: '卅十'.

For `day = 10`:
`a, b = divmod(10, 10)` -> `a = 1, b = 0`.
Since `b == 0`, `b = 10`.
`a` is 1, so `a = 0`.
Result: `TextUtils.TENS[0] + TextUtils.DAYS_CN[10]`.
`TENS[0]` = '初'.
`DAYS_CN[10]` = '十'.
Result: '初十'. (Actually, 10th is often "初十" or just "十", but the current logic gives "初十"). Wait, wait. `TENS[0]` is '初'. So `TENS[0] + DAYS_CN[10]` is '初十'.

Wait, usually 10th of the lunar month is "初十". But notice:
`day = 1`: `a=0, b=1` -> `TENS[0] + DAYS_CN[1]` -> '初一'.
`day = 9`: `a=0, b=9` -> `TENS[0] + DAYS_CN[9]` -> '初九'.
`day = 10`: `a=1, b=0` -> `a=0, b=10` -> `TENS[0] + DAYS_CN[10]` -> '初十'.

For `day = 11`: `a=1, b=1` -> `TENS[1] + DAYS_CN[1]` -> '十一'.
For `day = 19`: `a=1, b=9` -> `TENS[1] + DAYS_CN[9]` -> '十九'.

For `day = 20`: `a=2, b=0` -> `a=2, b=10` -> `TENS[2] + DAYS_CN[10]` -> '廿十'.

The problem is that for 20 and 30, we should not append '十' if we use '廿' or '卅'.
Wait, but if `day = 20`, it should be '二十'.
'二十' is `TENS[1]` ('十') + `DAYS_CN[2]` ('二')? No, that's not how `day_cn` is currently structured.

Let's see:
`TENS = '初十廿卅'`
`DAYS_CN = '日一二三四五六七八九十'`

If we want '二十':
'二' is `DAYS_CN[2]`.
'十' is `TENS[1]` or `DAYS_CN[10]`.

If `day = 20`, we want '二十'.
Current: `TENS[2]` ('廿') + `DAYS_CN[10]` ('十') = '廿十'.

If the author says "Correct should be 二十, 三十", then for `day=20`, it should be '二十'.
And for `day=30`, it should be '三十'.

Wait, is "廿" used for 20-29?
`day = 21`: `a=2, b=1` -> `TENS[2]` ('廿') + `DAYS_CN[1]` ('一') = '廿一'.
This is a common and acceptable way to say 21 in lunar calendar.

So for 20, we have a choice: '廿' or '二十'.
The issue says "廿十" is incorrect because "廿" itself means 20.
So for `day = 20`, it should be '廿' or '二十'.
The issue specifically says "正确的应该为'二十'、'三十'".

So:
`day = 20` -> '二十'
`day = 30` -> '三十'

Wait, if I change `day=20` to '二十', I'm using `DAYS_CN[2]` + `DAYS_CN[10]`? No, that's '二十'.
But `TENS[1]` is '十'. So `DAYS_CN[2] + TENS[1]`? No.

Let's look at the logic again.
For `day = 11` to `19`, it's `TENS[1]` ('十') + `DAYS_CN[1]` to `DAYS_CN[9]`. '十一' to '十九'. Correct.

For `day = 20`:
We want '二十'.
`DAYS_CN[2]` is '二'.
`DAYS_CN[10]` is '十'.
So `DAYS_CN[2] + DAYS_CN[10]`?

Wait, look at `day = 10`:
Current code: `a=1, b=0` -> `a=0, b=10`. Result: `TENS[0] + DAYS_CN[10]` = '初十'.
This is correct for the 10th of the lunar month.

For `day = 20`:
If we want '二十', we can't just use `TENS[2] + DAYS_CN[10]`.
If we use `DAYS_CN[2] + DAYS_CN[10]`, we get '二十'.

But what about `day = 21`?
Current: `TENS[2] + DAYS_CN[1]` = '廿一'. This is usually fine.

Let's re-read the issue:
"“廿十”、“卅十” 是不正确的用法,因为“廿”、“卅” 本身就是二十、三十的意思了,正确的应该为“二十”、“三十”。"

So for `day=20`, it should be '二十' (or just '廿' maybe, but they specifically said '二十').
For `day=30`, it should be '三十' (or just '卅', but they said '三十').

If `day = 20`:
`a = 2, b = 0`.
If we change it to `a=1, b=2`? No.
If we just handle `day == 20` and `day == 30` as special cases?

Or, if `b == 0` (meaning day is 10, 20, 30):
If `day == 10`: '初十' (TENS[0] + DAYS_CN[10])
If `day == 20`: '二十' (DAYS_CN[2] + DAYS_CN[10])
If `day == 30`: '三十' (DAYS_CN[3] + DAYS_CN[10])

Wait, `DAYS_CN[2]` is '二', `DAYS_CN[10]` is '十'. So `DAYS_CN[2] + DAYS_CN[10]` is '二十'.
`DAYS_CN[3]` is '三', `DAYS_CN[10]` is '十'. So `DAYS_CN[3] + DAYS_CN[10]` is '三十'.

Let's see where the current code goes for `day=20`:
`a=2, b=0` -> `b=10, a=2` -> `TENS[2] + DAYS_CN[10]` -> '廿十'.

If we want '二十', we can change the logic for `b == 0`.

```python
    @staticmethod
    def day_cn(day: int) -> str:
        a, b = divmod(day, 10)
        if b == 0:  # 10, 20, 30
            if day == 10:
                return '初十'
            if day == 20:
                return '二十'
            if day == 30:
                return '三十'
        return TextUtils.TENS[a] + TextUtils.DAYS_CN[b]
```
But wait, `LUNAR_DATE` days can be up to 30.
What about `day = 10`?
`a=1, b=0`.
`TENS[0]` is '初', `DAYS_CN[10]` is '十'.
So `TENS[0] + DAYS_CN[10]` is '初十'.

What about other days?
`day = 1`: `a=0, b=1` -> `TENS[0] + DAYS_CN[1]` -> '初一'.
`day = 11`: `a=1, b=1` -> `TENS[1] + DAYS_CN[1]` -> '十一'.
`day = 21`: `a=2, b=1` -> `TENS[2] + DAYS_CN[1]` -> '廿一'.
`day = 31`: (not possible in lunar usually, but `day_cn` should handle it if it does). `a=3, b=1` -> `TENS[3] + DAYS_CN[1]` -> '卅一'.

Wait, if we want '二十' for 20 and '三十' for 30, we could do this:

```python
    @staticmethod
    def day_cn(day: int) -> str:
        if day == 20:
            return '二十'
        if day == 30:
            return '三十'
        a, b = divmod(day, 10)
        if b == 0:  # 10, 20, 30 (but we already handled 20, 30)
            b = 10
            if a == 1:  # 10
                a = 0
        return TextUtils.TENS[a] + TextUtils.DAYS_CN[b]
```

But let's see if we can do it more elegantly within the existing structure.
Current logic for `b == 0`:
`b = 10`, and if `a == 1`, `a = 0`.
So for `day=10`, `a=0, b=10` -> '初十'.
For `day=20`, `a=2, b=10` -> '廿十'.
For `day=30`, `a=3, b=10` -> '卅十'.

If we change the `b == 0` block to:
```python
        if b == 0:  # 10,20,30
            if day == 10:
                return '初十'
            return TextUtils.DAYS_CN[day // 10] + TextUtils.DAYS_CN[10]
```
For `day=20`, `day // 10` is 2. `DAYS_CN[2]` is '二', `DAYS_CN[10]` is '十'. -> '二十'.
For `day=30`, `day // 10` is 3. `DAYS_CN[3]` is '三', `DAYS_CN[10]` is '十'. -> '三十'.

However, let's check if '二十' can be expressed as `TENS[1] + DAYS_CN[2]`?
`TENS[1]` is '十'. `DAYS_CN[2]` is '二'.
So `TENS[1] + DAYS_CN[2]` is '十二', not '二十'.

So the logic for 20 and 30 must be different from 11-19.

Actually, a simpler fix is to just handle 20 and 30 explicitly or change the return for `b==0` and `a > 1`.

```python
    @staticmethod
    def day_cn(day: int) -> str:
        a, b = divmod(day, 10)
        if b == 0:  # 10,20,30
            b = 10
            if a == 1:  # 10
                a = 0
            elif a > 1: # 20, 30
                 return TextUtils.DAYS_CN[a] + TextUtils.DAYS_CN[10]
        return TextUtils.TENS[a] + TextUtils.DAYS_CN[b]
```

Wait, if `a = 2, b = 10`, `TextUtils.TENS[2]` is '廿'.
If we want '二十', we use `TextUtils.DAYS_CN[2]` ('二') + `TextUtils.DAYS_CN[10]` ('十').

Let's verify:
`DAYS_CN = '日一二三四五六七八九十'`
`DAYS_CN[2]` is '二' (index 0:日, 1:一, 2:二).
`DAYS_CN[10]` is '十' (index 10).

So `TextUtils.DAYS_CN[2] + TextUtils.DAYS_CN[10]` is indeed '二十'.

What if `day = 10`?
`a=1, b=0`.
`b=10`. `a==1` is true, so `a=0`.
Return `TENS[0] + DAYS_CN[10]` -> '初十'.
Correct.

What if `day = 20`?
`a=2, b=0`.
`b=10`. `a==1` is false. `a > 1` is true.
Return `DAYS_CN[2] + DAYS_CN[10]` -> '二十'.
Correct.

What if `day = 30`?
`a=3, b=0`.
`b=10`. `a==1` is false. `a > 1` is true.
Return `DAYS_CN[3] + DAYS_CN[10]` -> '三十'.
Correct.

Wait, if `a` is 0 (e.g. `day=0`? not possible for dates), then it doesn't hit `a > 1`.

Let's re-verify all days from 1 to 30.
- 1: `a=0, b=1` -> `TENS[0] + DAYS_CN[1]` = '初一'
- 9: `a=0, b=9` -> `TENS[0] + DAYS_CN[9]` = '初九'
- 10: `a=1, b=0` -> `b=10, a=0` -> `TENS[0] + DAYS_CN[10]` = '初十'
- 11: `a=1, b=1` -> `TENS[1] + DAYS_CN[1]` = '十一'
- 19: `a=1, b=9` -> `TENS[1] + DAYS_CN[9]` = '十九'
- 20: `a=2, b=0` -> `b=10, a=2` -> `a > 1` -> `DAYS_CN[2] + DAYS_CN[10]` = '二十'
- 21: `a=2, b=1` -> `TENS[2] + DAYS_CN[1]` = '廿一'
- 29: `a=2, b=9` -> `TENS[2] + DAYS_CN[9]` = '廿九'
- 30: `a=3, b=0` -> `b=10, a=3` -> `a > 1` -> `DAYS_CN[3] + DAYS_CN[10]` = '三十'

This looks perfect and preserves the current behavior for all other days.

Wait, is there any other `day_cn`? The issue said:
"只需要修改 `TextUtils.day_cn` 逻辑即可,其他函数均是调用该函数。"
So I only need to modify `TextUtils.day_cn`.

Let's check if there are other classes with `day_cn`.
`grep -rn "def day_cn" .` should have found all.

What about other days? `day = 1`: `a=0, b=1` -> `TENS[0] + DAYS_CN[1]` -> '初一'. `day = 11`: `a=1, b=1` -> `TENS[1] + DAYS_CN[1]` -> '十一'. `day = 21`: `a=2, b=1` -> `TENS[2] + DAYS_CN[1]` -> '廿一'. `day = 31`: (not possible in lunar usually, but `day_cn` should handle it if it does). `a=3, b=1` -> `TENS[3] + DAYS_CN[1]` -> '卅一'. Wait, if we want '二十' for 20 and '三十' for 30, we could do this: ```python @staticmethod def day_cn(day: int) -> str: if day == 20: return '二十' if day == 30: return '三十' a, b = divmod(day, 10) if b == 0: # 10, 20, 30 (but we already handled 20, 30) b = 10 if a == 1: # 10 a = 0 return TextUtils.TENS[a] + TextUtils.DAYS_CN[b] ``` But let's see if we can do it more elegantly within the existing structure. Current logic for `b == 0`: `b = 10`, and if `a == 1`, `a = 0`. So for `day=10`, `a=0, b=10` -> '初十'. For `day=20`, `a=2, b=10` -> '廿十'. For `day=30`, `a=3, b=10` -> '卅十'. If we change the `b == 0` block to: ```python if b == 0: # 10,20,30 if day == 10: return '初十' return TextUtils.DAYS_CN[day // 10] + TextUtils.DAYS_CN[10] ``` For `day=20`, `day // 10` is 2. `DAYS_CN[2]` is '二', `DAYS_CN[10]` is '十'. -> '二十'. For `day=30`, `day // 10` is 3. `DAYS_CN[3]` is '三', `DAYS_CN[10]` is '十'. -> '三十'. However, let's check if '二十' can be expressed as `TENS[1] + DAYS_CN[2]`? `TENS[1]` is '十'. `DAYS_CN[2]` is '二'. So `TENS[1] + DAYS_CN[2]` is '十二', not '二十'. So the logic for 20 and 30 must be different from 11-19. Actually, a simpler fix is to just handle 20 and 30 explicitly or change the return for `b==0` and `a > 1`. ```python @staticmethod def day_cn(day: int) -> str: a, b = divmod(day, 10) if b == 0: # 10,20,30 b = 10 if a == 1: # 10 a = 0 elif a > 1: # 20, 30 return TextUtils.DAYS_CN[a] + TextUtils.DAYS_CN[10] return TextUtils.TENS[a] + TextUtils.DAYS_CN[b] ``` Wait, if `a = 2, b = 10`, `TextUtils.TENS[2]` is '廿'. If we want '二十', we use `TextUtils.DAYS_CN[2]` ('二') + `TextUtils.DAYS_CN[10]` ('十'). Let's verify: `DAYS_CN = '日一二三四五六七八九十'` `DAYS_CN[2]` is '二' (index 0:日, 1:一, 2:二). `DAYS_CN[10]` is '十' (index 10). So `TextUtils.DAYS_CN[2] + TextUtils.DAYS_CN[10]` is indeed '二十'. What if `day = 10`? `a=1, b=0`. `b=10`. `a==1` is true, so `a=0`. Return `TENS[0] + DAYS_CN[10]` -> '初十'. Correct. What if `day = 20`? `a=2, b=0`. `b=10`. `a==1` is false. `a > 1` is true. Return `DAYS_CN[2] + DAYS_CN[10]` -> '二十'. Correct. What if `day = 30`? `a=3, b=0`. `b=10`. `a==1` is false. `a > 1` is true. Return `DAYS_CN[3] + DAYS_CN[10]` -> '三十'. Correct. Wait, if `a` is 0 (e.g. `day=0`? not possible for dates), then it doesn't hit `a > 1`. Let's re-verify all days from 1 to 30. - 1: `a=0, b=1` -> `TENS[0] + DAYS_CN[1]` = '初一' - 9: `a=0, b=9` -> `TENS[0] + DAYS_CN[9]` = '初九' - 10: `a=1, b=0` -> `b=10, a=0` -> `TENS[0] + DAYS_CN[10]` = '初十' - 11: `a=1, b=1` -> `TENS[1] + DAYS_CN[1]` = '十一' - 19: `a=1, b=9` -> `TENS[1] + DAYS_CN[9]` = '十九' - 20: `a=2, b=0` -> `b=10, a=2` -> `a > 1` -> `DAYS_CN[2] + DAYS_CN[10]` = '二十' - 21: `a=2, b=1` -> `TENS[2] + DAYS_CN[1]` = '廿一' - 29: `a=2, b=9` -> `TENS[2] + DAYS_CN[9]` = '廿九' - 30: `a=3, b=0` -> `b=10, a=3` -> `a > 1` -> `DAYS_CN[3] + DAYS_CN[10]` = '三十' This looks perfect and preserves the current behavior for all other days. Wait, is there any other `day_cn`? The issue said: "只需要修改 `TextUtils.day_cn` 逻辑即可,其他函数均是调用该函数。" So I only need to modify `TextUtils.day_cn`. Let's check if there are other classes with `day_cn`. `grep -rn "def day_cn" .` should have found all. <channel|><|tool_call>call:run_command{command:<|"|>grep -rn "def day_cn" borax/<|"|>}<tool_call|><|tool_response>

Only one implementation.

Now let's implement the fix.

```python
    @staticmethod
    def day_cn(day: int) -> str:
        a, b = divmod(day, 10)
        if b == 0:  # 10,20,30
            b = 10
            if a == 1:  # 10
                a = 0
            elif a > 1:  # 20,30
                return TextUtils.DAYS_CN[a] + TextUtils.DAYS_CN[10]
        return TextUtils.TENS[a] + TextUtils.DAYS_CN[b]
```

Wait, looking at the existing code:
```python
    @staticmethod
    def day_cn(day: int) -> str:
        a, b = divmod(day, 10)
        if b == 0:  # 10,20,30
            b = 10
            if a == 1:  # 10
                a = 0
        return TextUtils.TENS[a] + TextUtils.DAYS_CN[b]
```

I can change it to:
```python
    @staticmethod
    def day_cn(day: int) -> str:
        a, b = divmod(day, 10)
        if b == 0:  # 10,20,30
            if a == 1:  # 10
                return TextUtils.TENS[0] + TextUtils.DAYS_CN[10]
            if a > 1:  # 20,30
                return TextUtils.DAYS_CN[a] + TextUtils.DAYS_CN[10]
            # b=0 and a=0? day=0.
        return TextUtils.TENS[a] + TextUtils.DAYS_CN[b]
```
Wait, `a=0, b=0` would mean `day=0`.
If `day=10`, `a=1, b=0`. Return `TENS[0] + DAYS_CN[10]` = '初十'.
If `day=20`, `a=2, b=0`. Return `DAYS_CN[2] + DAYS_CN[10]` = '二十'.
If `day=30`, `a=3, b=0`. Return `DAYS_CN[3] + DAYS_CN[10]` = '三十'.

What if `day=1`? `a=0, b=1`. Not `b==0`. Return `TENS[0] + DAYS_CN[1]` = '初一'.
What if `day=11`? `a=1, b=1`. Not `b==0`. Return `TENS[1] + DAYS_CN[1]` = '十一'.

This also works and is quite clean.

But I should try to keep the existing logic for `day=10` as it was (just slightly modified) to avoid unnecessary changes.

Existing:
```python
        if b == 0:  # 10,20,30
            b = 10
            if a == 1:  # 10
                a = 0
```
If I add:
```python
            elif a > 1:  # 20,30
                return TextUtils.DAYS_CN[a] + TextUtils.DAYS_CN[10]
```
Then for `day=10`: `b=10, a=0`. Return `TENS[0] + DAYS_CN[10]` = '初十'.
For `day=20`: `b=10, a=2`. Hit `elif a > 1`, return `DAYS_CN[2] + DAYS_CN[10]` = '二十'.
For `day=30`: `b=10, a=3`. Hit `elif a > 1`, return `DAYS_CN[3] + DAYS_CN[10]` = '三十'.

This is very minimal.

The diff is clean and reflects the stated change.
The fix correctly addresses the issue:
- For `day=20`, it now returns '二十' instead of '廿十'.
- For `day=30`, it now returns '三十' instead of '卅十'.
- For `day=10`, it still returns '初十'.
- For other days, behavior is preserved.

I am confident in this fix.

Final check on all requirements:
- Minimal root-cause patch: Yes, 2 lines added.
- Passed failing and regression tests: Yes.
- Fixed in production source: Yes.
- No changes to `tests/`: Yes.
- No untracked files: Yes.

One detail: I should check if `Telugu` or other calendars are used, but `LunarDate` seems to be the only one here. The issue specifically mentioned `borax.calendars.lunardate.LunarDate` and `TextUtils.day_cn`.

Wait, I should be sure that `TENS[a] + DAYS_CN[b]` is still correct for `a=2, b=1` ('廿一').
If `day=21`: `a=2, b=1`. `b==0` is false. Result: `TENS[2] + DAYS_CN[1]` = '廿' + '一' = '廿一'. Correct.
If `day=31`: (though lunar month usually 29 or 30 days, it could happen if someone initializes it). `a=3, b=1`. `b==0` is false. Result: `TENS[3] + DAYS_CN[1]` = '卅' + '一' = '卅一'. Correct.

The logic holds.
