A technique census of Phase 1: what the mathematics is doing, what walls it hit, and what's still open

@bgrubbs1984 I liked the visual-notebook suggestion, so I turned my public-safe atlas into a five-map executable companion: How 203 experiments reached public #16: five maps of Phase 1.

It separates historical rank from evaluator epoch, maps accuracy against compute, shows where the 56 post-frontier ideas stopped, and includes the proof pipeline. The Kaggle version executes without challenge data or network access. If the census gets a consolidated post-Aug-17 pass, feel free to link whichever map is most useful.
