+# Week 02 Progress Report by Nikhil Bhatt
+
+**Project:** [Git backend for Musicblocks](https://github.com/benikk/musicblocks-backend)  
+**Mentors:** [Walter Bender](https://github.com/walterbender), [Sumit Srivastava](https://github.com/sum2it)  
+**Reporting Period:** 2025-06-7 – 2025-06-14  
+
+---
+
+## Goals for This Week
+
+- **Implement an edit route** to allow users to update project data securely using hashed keys.
+- **Design and implement a forking mechanism** where users can fork existing project repositories into new independent ones.
+- **Integrate project origin tracking** in forked repos through metadata.
+
+---
+
+## This Week's Achievements
+
+1. **Edit Project Functionality**
+   - Created a secure API endpoint that allows users to update their project repository content using a key-authenticated system.
+   - The backend checks the key hash stored in the `metaData.json` before applying any updates.
+   - PR: [Edit Project API](https://github.com/BeNikk/musicblocks-backend/commit/1f61a089de7d8dbede2d46a101611133a1190bf6)
+
+2. **Fork Project Repository**
+   - Developed a new feature that enables students to fork other students' public projects into their own repositories under the same organization.
+   - Forked repositories retain original content (`projectData.json`, `metaData.json`) and include the original repository link in the metadata (`forkedFrom` field).
+   - PR: [Fork Feature](https://github.com/BeNikk/musicblocks-backend/commit/d1b7220476dc1fd58c1b38dc59c8a4991871ac45)
+
+3. **Project Metadata Enhancements**
+   - Updated the metadata structure to support fork tracking and improve key validation.
+   - Ensured consistency between project ownership, fork source, and editing rights.

+
+## Challenges & How I Overcame Them
+
+- **Challenge:** Understanding and handling GitHub’s `SHA` and `Base64` requirements when editing file content through the API.  
+  **Solution:** Read GitHub API docs and integrated `Buffer.from(...).toString('base64')` and used file `sha` to ensure proper file overwrites.
+
+- **Challenge:** Unsure if re-initializing Octokit and generating a new installation token per request was optimal.  
+  **Solution:** Kept this approach for now as each request is stateless and works correctly. Optimization will be explored after baseline features are stable.
+
+---
+
+## Key Learnings
+
+- Learned how to **authenticate and authorize edits** to GitHub repos using hashed keys and GitHub’s content API.
+- Understood the internal structure of GitHub forks and metadata handling.
+- Improved knowledge of **Octokit**, GitHub APIs, and best practices for writing file content (`projectData.json`, `metaData.json`) to a repo.
+
+---
+
+## Next Week's Roadmap
+
+- Add **pull request functionality** between forked and original projects.
+- Improve project listing UI with fork indicators.
+- Begin planning for collaborator permissions and PR review workflow.
+
+---
+
+## Resources & References
+
+- **GitHub API Docs:** [REST Reference](https://docs.github.com/en/rest)
+- **Octokit:** [octokit/rest.js](https://github.com/octokit/rest.js)
+- **MetaData Example:** `metaData.json` includes `hashedKey`, `theme`, and `forkedFrom`.
