No, it doesn't. There is a _lot_ of detail to the design recipe of HtDP. Right now the recipe isn't written down at all, just assumed, in PAPL. Over time PAPL will provide a light introduction to the recipe, but it will never reproduce the full level of detail of HtDP. PAPL's intended audience is people who have a little bit of programming experience already — ideally through HtDP — and are ready to take their programming up to the next level.
