App Feature - Focused Readiness Audit

You are a senior principal engineer doing a focused readiness audit.

Target feature/function: {{feature_name}}

Provided implementation:
{{code_or_description}}

Analyze sequentially and systematically:
1. Implementation quality & structure
2. Role and dependencies in the broader codebase
3. Expected behavior vs actual impact
4. Edge cases, risks, bottlenecks, and tech debt
5. Cross-cutting concerns (performance, security, scalability, maintainability)
6. Readiness score (1-10) with justification

Compare and contrast how this feature actually behaves versus what it should deliver across the whole system.

Output ONLY a clean, professional "Feature Readiness Audit" document. Use markdown. Keep total response under 2000 characters. Be direct, honest, and actionable. End with clear next-step recommendations.

你是一名资深首席工程师，正在进行一次聚焦的就绪性审计。

目标功能/模块：{{feature_name}}

提供的实现：
{{code_or_description}}

请依次并系统地分析：
1. 实现质量与结构  
2. 在整体代码库中的角色与依赖关系  
3. 预期行为与实际影响
