🔗 Critical Dependency Chains

Must Complete First:

1. #35 → #36, #37, #38, #39 (Audit informs everything)
2. #36 → #37, #38, #39, #41, #45 (Architecture guides implementation)
3. #37 → #38, #39, #41, #45 (Type conversion needed for all bridges)
4. #40 → All testing (Test infrastructure foundation)

Service Bridge Chain:

#38 (Service Types) → #41 (Client) → #42 (Server) → #43 (Python) → #44 (C++)

Action Bridge Chain:

#39 (Action Types) → #45 (Client) → #46 (Server) → #47 (Python) → #48 (C++) → #49 (State Machine)

Advanced Features Chain:

#41 + #45 → #50 (Discovery) → #51 (QoS) → #52 (Parameters) → #53 (TF2) → #54 (Errors)

🚀 Getting Started

For Implementers:

1. Start with Issue #35 (Audit)

   • Read 035-ros2-bridge-audit.md
   • Document gaps and requirements
   • Create detailed analysis

2. Follow Dependency Order

   • Check issue file for dependencies
   • Use the dependency chains above as your guide
   • Never start before dependencies complete

3. Use Issue Files

   • Each .md file has complete specifications
   • Follow the patterns and examples
   • Reference implementation code

For Project Managers:

1. Convert to GitHub Issues

   • Each .md file → GitHub issue
   • Link dependencies in GitHub
   • Assign to developers

2. Track Progress

   • Update status in this README
   • Monitor dependency blockers
   • Adjust as needed

3. AI-Assisted Development

   • Issues designed for AI pair programming
   • Detailed specs enable AI code generation
   • Focus on review and integration
