+# Week 4 Progress Report by Safwan Sayeed
+
+**Project:** Music Blocks 4 Program Engine  
+**Mentors:** [Anindya Kundu](https://github.com/meganindya/), [Sumit Srivastava](https://github.com/sum2it)  
+**Assisting Mentors:** [Devin Ullibari](https://github.com/pikurasa/), [Walter Bender](https://github.com/walterbender)  
+**Reporting Period:** 2025-06-23 - 2025-06-29

+
+## A Blog-style Retrospective
+
+This week marked a significant milestone in our Music Blocks program engine development as we transitioned from the foundational memory architecture to the core compilation logic. The focus shifted to implementing the AST-to-IR (Intermediate Representation) translation layer - the crucial bridge between our abstract syntax tree representation and executable code.
+
+---
+
+## Goals for This Week
+
+- Complete the AST-to-IR compilation logic technical specification with detailed pseudocode patterns.
+- Implement the AST Parsing logic for all expression classes returning instruction lists.
+---
+
+## This Week's Highlights
+
+1. **AST-to-IR Compilation Logic Specification**  
+   - Expanded the tech spec with comprehensive AST-to-IR translation documentation covering expression and statement compilation patterns.
+   - Detailed instruction list generation requirements and variable management strategies.
+   - Link: [IR Compilation Logic](https://docs.google.com/document/d/1_MCCgl-RqiEQH0UQ4EX-2O6G4iRxgHAY1rZpw3QPXT0/edit?tab=t.i655udul8zuq)
+
+2. **Implemented AST Parsing Logic**
+   - Developed parsing logic for all expression classes, ensuring they return the correct instruction lists.  
+
+---
+
+## Challenges & Solutions
+
+- **Understanding Static vs Runtime Compilation:**  
+  Initially confused about whether we were performing runtime calculations or static code translation.  
+  *Solution:* Mentors clarified that this is purely static AST-to-IR conversion with no runtime execution, helping focus the implementation approach.
+
+
+---
+
+## Key Learnings
+
+- Gained a deeper understanding of static compilation principles and the importance of maintaining clean instruction generation patterns.
+- Learned how to effectively manage variable scopes and dependencies during the AST-to-IR translation process.
+
+---
+
+## Next Week's Roadmap
+
+- Finalize the AST-to-IR compilation logic implementation for all expression and statement classes.
+- Begin integrating the IR generation with the memory management system to ensure proper variable resolution.
+- Start working on the execution engine that will interpret the generated IR instructions.

+## Acknowledgments
+
+Special thanks to my mentors Anindya, Sumit, Devin, and Walter for their crucial guidance on compiler design principles and static compilation concepts. Their clarification on the AST-to-IR translation approach and emphasis on maintaining clean instruction generation patterns was essential for this week's successful progress.
