新供给补缺口：用闭环把AI风险重新变得可保所谓新供给，核心不是卖一张保单，而是交付一个闭环：评估、承保、监控。当传统市场收缩敞口时，谁能补位甚至敢扩限额，取决于谁能把AI风险变成可承保对象。

To test this I built gitgres, about 2,000 lines of C implementing the libgit2 git_odb_backend and git_refdb_backend interfaces against Postgres through libpq, plus roughly 200 lines of PL/pgSQL for the storage functions. libgit2 handles pack negotiation, delta resolution, ref advertisement, and the transport protocol while the backend reads and writes against the two tables, and a git remote helper (git-remote-gitgres) lets you add a Postgres-backed remote to any repo and push or clone with a normal git client that has no idea it’s talking to a database. There’s a Dockerfile in the repo if you want to try it out without building libgit2 and libpq from source.
