Preserve daily-token prose as transcript, JSON and source files and verify pinned bytes before minting. Add readable rich text, named links and podcast readalong data with cached layout and media-clock highlighting. Add opt-in seeded execution and work limits, audited numeric plans, an f64 Wasm backend and 32 exact CPU-render golden frames. Stop boot color probing from executing arbitrary operations. Keep browser checks in development mode. Include a standalone reflective-sphere preview and a four-backend benchmark. Wasm compiles the numeric ray/sphere kernel; scene traversal and shading remain JavaScript. Rebuild the disk worker and sync its reference source. Validation: 55 focused Node tests, 29 Jasmine specs, color-pattern checks, worker integrity, exact RGBA parity across ray kernels, six-piece browser worker comparison, and interactive preview playback/controls.
