The code was getting heavy, and the AI latency was killing the user experience. Today, I finished a 'Heart Surgery' refactor to prepare for our May 30th acquisition target.</p> <p>Here is how we stabilized the engine:</p> <ol> <li><p>The 5,000-Line Purge 🏗️<br> We successfully de-monolithized the app, dropping the main core to 4,894 lines of lean, production-ready Python. By extracting telemetry and heavy logic into /core, we achieved a modular architecture that's actually audit-ready.</p></li> <li><p>0.94s Latency: The 'Unfiltered' Move ⚡<br> We evicted all legacy rate-limiters. By utilizing a proprietary Semantic Normalizer + Redis Edge-Cache pipeline, we’re now delivering TTRPG adjudication in sub-seconds via Groq and OpenAI failovers.</p></li> <li><p>The 'Ghost-Buster' Protocol 🧹<br> To ensure our Viberank #3 spot is backed by 100% verified data, I deployed a real-time Firestore purge. Our 2 Active GMs are real, live human hearts beating in our engine—no ghost sessions allowed.</p></li> </ol> <p>The Goal: 57 days to exit. Every line of code must earn its keep.</p> <p>Watch the Live Pulse: dm-copilot-cloud.onrender.com 💓</p> ai python gamedev cloud
