Sounds thrilling, but remember the prototype will be a double‑edged sword—great for raw insights, but also a minefield of false positives. Quick iteration is fine, yet make sure you log every buzz so you can debug the signal later. A wearable that just blinks at sadness could miss context—maybe start with a simple threshold, then layer in some self‑check to avoid spiraling into the chaos you love. Keep the code lean, but build in a pause button for safety. The human touch will be the real test. Good luck, just keep a little sanity margin on that loop.
