The issue requested a detailed code quality evaluation of the project (详细评价一下这个项目的代码质量).

Assessment Delivered

Created CODE_QUALITY_REVIEW.md - a bilingual (Chinese/English) technical assessment covering:

• Architecture & Structure: Modular design with clear separation of concerns across 13 files (~2,100 LOC)
• Type & Memory Safety: Minimal unsafe usage (5 instances, FFI-only), proper memory management
• Error Handling: Consistent anyhow usage with rich context, 8 unwrap() calls identified for improvement
• Security: Crypto-safe RNG, TOTP implementation, privilege checks; noted danger_accept_invalid_certs
• Tooling: Zero Clippy warnings, rustfmt compliance
• Testing: 0% coverage - primary improvement opportunity
• Documentation: Strong README/changelog, missing API docs and architecture diagrams
• Platform Support: Clean conditional compilation for Linux/Windows/macOS

Overall Rating: 7.5/10

Strengths: solid engineering fundamentals, type-safe design, good error context.
Critical gap: test coverage.

Priority recommendations ranked by impact with specific file references and remediation guidance.
