+# Week 02 Progress Report by Aman Chadha
+
+**Project:** [JS Internationalization with AI Translation Support](https://github.com/sugarlabs/musicblocks/pull/4459)  
+**Mentors:** [Walter Bender](https://github.com/walterbender)  
+**Assisting Mentors:** *None this week*  
+**Reporting Period:** 2025-06-09 - 2025-06-16  
+
+---
+
+## Goals for This Week
+
+- **Refactor RAG model output** to a structured dictionary format that includes part-of-speech (POS) tagging.
+- **Optimize AST-based chunking** by limiting code context to 5 lines above and below translation usage, per mentor feedback.
+- **Begin functional testing** of the updated RAG pipeline on real-world translation queries.
+
+---
+
+## This Week's Achievements
+
+1. **RAG Output Enhancement**  
+   - Refactored the Retrieval-Augmented Generation model to return results as structured dictionaries.
+   - Each entry now includes `msgid`, `msgstr`, source metadata, and the dominant part of speech, improving retrieval relevance.
+
+2. **Code Chunking Optimization**  
+   - Reduced each extracted code chunk to include only 5 lines above and below the relevant `msgid` usage.
+   - This improves retrieval precision and avoids irrelevant surrounding code.  
+   - Implemented using Babel’s AST traversal logic.
+
+3. **Initial Model Testing**  
+   - Started testing the RAG model using sample translation queries.
+   - Observed noticeable improvements in answer context relevance due to cleaner chunks and richer metadata.
+
+---
+
+## Challenges & How I Overcame Them
+
+- **Challenge:** Integrating POS tagging meaningfully into the RAG data pipeline.  
+  **Solution:** Designed a dictionary schema that includes the part-of-speech alongside translation metadata, and verified correctness using test entries.
+
+- **Challenge:** Tuning chunk granularity without losing contextual utility.  
+  **Solution:** Followed mentor Walter’s advice to use fixed ±5 line windows, and manually verified semantic coherence of resulting chunks.
+
+---
+
+## Key Learnings
+
+- Part-of-speech tagging can significantly improve the contextual strength of retrieved translations.
+- Smaller, focused code chunks often result in better retrieval precision for RAG applications.
+- Mentor feedback and collaborative iteration are key to refining both code structure and user outcomes.
+
+---
+
+## Next Week's Roadmap
+
+- Integrate POS-tagged RAG responses into the full i18n fallback translation pipeline.
+- Expand test coverage to include edge-case translations and re-used `msgid`s.
+- Prepare an internal demo to show RAG-powered retrieval resolving contextually ambiguous translation strings.
