1. Location labels inflate precision 🐞 Bug ≡ Correctness
Ground truth is collapsed to (path, start_line), but the bundled corpus assigns both false and true to src/handler.py:13; any candidate that retains both differently categorized comments will count both as true. This can falsely improve precision and allow a bad rule optimization to pass its evaluation gate.
Agent Prompt
## Issue description
The harness overwrites ground-truth labels for comments that share a source location, so distinct comments can receive the wrong `fixed_later` value and inflate precision.
## Issue Context
The bundled corpus contains two different comments at `src/handler.py:13` with conflicting labels. Ground truth must remain associated with the exact comment through postprocessing rather than only its location.

2. Output failures use wrong exit 🐞 Bug ☼ Reliability
The report write occurs outside error handling, so an unwritable or unavailable output path raises OSError, prints a traceback, and exits with Python's default code 1. The harness documents infrastructure failures as exit 2, so callers cannot reliably classify this failure.
Agent Prompt
## Issue description
Report output I/O failures escape uncaught and violate the harness's documented infrastructure exit-code contract.
## Issue Context
`Path.write_text` can raise `OSError`; route that failure through the existing fatal infrastructure path so it exits 2 without an unhandled traceback.

处理缺失的选项值。
当 --corpus、--diff、--rules 或 --out 位于命令行末尾时，sys.argv[index + 1] 会抛出 IndexError。将缺失值视为空字符串，使 main() 按预期打印用法并返回 1。
建议修改

- return sys.argv[sys.argv.index(name) + 1] if name in sys.argv else ""

+ return sys.argv[index + 1] if index + 1 < len(sys.argv) else ""📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

将报告写入错误转换为退出码 2。
当输出目录不存在、无写权限或磁盘写入失败时，write_text() 会抛出未处理的 OSError 并以退出码 1 结束。该情况属于文档定义的 infra 失败，应通过 die2() 返回退出码 2。
建议修改
