+# Development Guidelines
+
+## Philosophy
+
+### Core Beliefs
+
+- **Incremental progress over big bangs** - Small changes that compile and pass tests
+- **Learning from existing code** - Study and plan before implementing
+- **Pragmatic over dogmatic** - Adapt to project reality
+- **Clear intent over clever code** - Be boring and obvious
+
+### Simplicity Means
+
+- Single responsibility per function/class
+- Avoid premature abstractions
+- No clever tricks - choose the boring solution
+- If you need to explain it, it's too complex
+
+## Process
+
+### 1. Planning & Staging
+
+Break complex work into 3-5 stages. Document in `IMPLEMENTATION_PLAN.md`:
+
+```markdown
+## Stage N: [Name]
+**Goal**: [Specific deliverable]
+**Success Criteria**: [Testable outcomes]
+**Tests**: [Specific test cases]
+**Status**: [Not Started|In Progress|Complete]
+```
+- Update status as you progress
+- Remove file when all stages are done
+
+### 2. Implementation Flow
+
+1. **Understand** - Study existing patterns in codebase
+2. **Test** - Write test first (red)
+3. **Implement** - Minimal code to pass (green)
+4. **Refactor** - Clean up with tests passing
+5. **Commit** - With clear message linking to plan
+
+### 3. When Stuck (After 3 Attempts)
+
+**CRITICAL**: Maximum 3 attempts per issue, then STOP.
+
+1. **Document what failed**:
+   - What you tried
+   - Specific error messages
+   - Why you think it failed
+
+2. **Research alternatives**:
+   - Find 2-3 similar implementations
+   - Note different approaches used
+
+3. **Question fundamentals**:
+   - Is this the right abstraction level?
+   - Can this be split into smaller problems?
+   - Is there a simpler approach entirely?
+
+4. **Try different angle**:
+   - Different library/framework feature?
+   - Different architectural pattern?
+   - Remove abstraction instead of adding?
+
+## Technical Standards
+
+### Architecture Principles
+
+- **Composition over inheritance** - Use dependency injection
+- **Interfaces over singletons** - Enable testing and flexibility
+- **Explicit over implicit** - Clear data flow and dependencies
+- **Test-driven when possible** - Never disable tests, fix them
+
+### Code Quality
+
+- **Every commit must**:
+  - Compile successfully
+  - Pass all existing tests
+  - Include tests for new functionality
+  - Follow project formatting/linting
+
+- **Before committing**:
+  - Run formatters/linters
+  - Self-review changes
+  - Ensure commit message explains "why"
+
+### Error Handling
+
+- Fail fast with descriptive messages
+- Include context for debugging
+- Handle errors at appropriate level
+- Never silently swallow exceptions
+
+## Decision Framework
+
+When multiple valid approaches exist, choose based on:
+
+1. **Testability** - Can I easily test this?
+2. **Readability** - Will someone understand this in 6 months?
+3. **Consistency** - Does this match project patterns?
+4. **Simplicity** - Is this the simplest solution that works?
+5. **Reversibility** - How hard to change later?
+
+## Project Integration
+
+### Learning the Codebase
+
+- Find 3 similar features/components
+- Identify common patterns and conventions
+- Use same libraries/utilities when possible
+- Follow existing test patterns
+
+### Tooling
+
+- Use project's existing build system
+- Use project's test framework
+- Use project's formatter/linter settings
+- Don't introduce new tools without strong justification
+
+## Quality Gates
+
+### Definition of Done
+
+- [ ] Tests written and passing
+- [ ] Code follows project conventions
+- [ ] No linter/formatter warnings
+- [ ] Commit messages are clear
+- [ ] Implementation matches plan
+- [ ] No TODOs without issue numbers
+
+### Test Guidelines
+
+- Test behavior, not implementation
+- One assertion per test when possible
+- Clear test names describing scenario
+- Use existing test utilities/helpers
+- Tests should be deterministic
+
+## Important Reminders
+
+**NEVER**:
+- Use `--no-verify` to bypass commit hooks
+- Disable tests instead of fixing them
+- Commit code that doesn't compile
+- Make assumptions - verify with existing code
+
+**ALWAYS**:
+- Commit working code incrementally
+- Update plan documentation as you go
+- Learn from existing implementations
+- Stop after 3 failed attempts and reassess

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt

+  * 用户数据存储符合GDPR或相关数据保护法规。  
+* **NF-3.4 用户体验 (Usability)**  
+  * 界面设计简洁直观，关键操作按钮尺寸足够大，易于在移动或工业环境中单手操作。  
+  * 网络不稳定时，应优先保证音频清晰度，并有明确的网络状态提示。
+
+### **4\. 设计与AI集成指南 (Design & AI Integration)**
+
+* **UI/UE设计指南**：  
+  * **核心原则**：信息降噪，聚焦于协作视图。避免不必要的UI元素干扰现场人员的视线。  
+  * **AR交互**：AR标注工具栏应设计为可收缩式，默认最小化。标注的视觉效果应有足够的对比度，以适应各种复杂的现场环境光线。  
+  * **手势操作**：考虑引入简单的手势操作，如双击屏幕清除最后一次标注，以提升操作效率。  
+* **AI模型集成指南**：  
+  * **语音转文字 (STT)**：需选用或训练针对特定行业术语（如机械、医疗）进行优化的模型，以提高识别准确率。模型需在端侧或低延迟的云端运行，保证实时性。  
+  * **会议纪要生成**：采用大语言模型（LLM）进行文本摘要和信息提取。模型需被调整以准确识别“决策”、“任务分配”等关键意图。  
+  * **知识库查询**：建议采用RAG（检索增强生成）架构。后端需建立高效的文档索引，前端AI助手通过语义搜索匹配最相关的知识片段，并由LLM整合后生成自然语言答案。
