+## 2024-05-15 - Initial Bolt Journal Entry\n**Learning:** This repo is an agent configuration framework rather than a heavy JS/React app. The only code here is in `ultron-agent.js` and `init-ultron.js`. It uses the filesystem for memory.\n**Action:** Focus optimizations on the file I/O operations in `ultron-agent.js` which could be a bottleneck if the memory JSON grows large.
+## 2024-05-15 - Matrix Animation Optimization\n**Learning:** Found an O(n) operation inside the animation loop where `n` is the number of matrix columns (often 100+). Inside the loop, it was checking state properties and building an array `let activePools = []; if (state.scripts.devanagari)...` on every single frame *for every single column*. This caused massive redundant memory allocation and garbage collection churn.\n**Action:** Hoist array/object construction outside of tight drawing loops. Also replaced `setInterval` with `requestAnimationFrame` to prevent the background tab from burning CPU cycles.
