jtraverso/certo-math
Between having a mathematical idea and having a proof of it there is a lot of work that is not proving: find the object, break the false claims, measure what survives, reduce it to what it really is, assemble the rest. certo does that work, and every step returns a certificate anyone can re-check without trusting it. CLI + MCP.
