Jai Demo and Design Explanation (KEYNOTE) - Updated
summary
A new systems language demo shows a 300,000-line game compiled as a full clean build in 2.3 seconds, with about 3,000 lines generated during build. The compiler runs a user-replaceable meta program and workspace-based compile-time execution, exposes rich messages for plugins, and builds a live memory visualizer plus a memory debugger hook system. Manual memory management stays but tooling finds leaks (example: missing free in compute_options_hash), live per-frame reports run while the game stays interactive (~45 fps with debugging).
