▸case-01 I have spent the past month watching frontend web development courses, but I struggle to code anything independently. I know fundamental JavaScript and basic React concepts from completing guided follow-alongs. I'm deeply interested in music recommendation systems and have around 8 hours a week to spare for two weeks. Could you outline a practical application I can construct to truly master React? I need a breakdown that explains why this application forces me to apply key concepts, a list of bite-sized build phases showing what each phase teaches, strategies for working through bugs without copy-pasting solutions, a bonus extension goal, and an overall timeline estimate. | pass→pass | 25,808 | 17,838 | -31% | 1 | 1 | 0% | 3,270 | 2,931 | -10% | 0 | 0 | — |
▸case-02 I want to transition from basic Python syntax into building backend REST APIs using FastAPI. I am a beginner to server-side programming and have only done syntax exercises on interactive coding sites. I care a lot about personal finance and budgeting tools, and I can invest roughly 5 hours weekly over the next month. Please formulate a build plan for me. Give me a clear title matching my skill level, detail why this finance tool mandates learning backend fundamentals, provide structured milestones linked to exact skills learned in each step, explain how to troubleshoot roadblocks constructively rather than copying code blindly, and suggest an advanced feature to tackle afterwards. | fail→pass | 28,286 | 18,038 | -36% | 1 | 1 | 0% | 3,978 | 2,939 | -26% | 0 | 0 | — |
▸case-03 I am a software developer looking to pick up SQL and relational database modeling from scratch. So far I have only executed basic query examples in a browser sandbox.

Specify why this specific database schema forces core relational principles, break the build down into clear steps noting what each stage teaches, describe an effective approach to getting unstuck that avoids copy-pasting schema scripts, propose a stretch extension, and estimate the required time. | fail→pass | 33,777 | 22,685 | -33% | 1 | 1 | 0% | 4,898 | 3,941 | -20% | 0 | 0 | — |
