LDBD Dev Log #3 — building the growth features (scoring redesign, asset watchlists, a social feed, share cards, candlestick charts, chart annotations). How I re-scored ~127k production predictions into an annualized return, built a feed that respects the copycat rule, and stored chart drawings as JSON instead of images.
