Sync main (through #9821/#9820/#9822/#9768) into next. Conflicting package.json files keep next's version and intentional divergences (for example the cli's c12 v4) while taking main's dependency updates, including the samlify 2.13.1 and fast-xml-parser security bumps; the lockfile is regenerated from the reconciled set. The 13 source/doc/test conflicts take next's refactored architecture as the baseline; main's colliding fixes are re-applied on top in the following per-domain commits. Clean main fixes land via this merge, including the auto-restored account-takeover defenses #9578 and #9577.
Better Auth
Better Auth is a framework-agnostic authentication (and authorization) framework for TypeScript. It provides a comprehensive set of features out of the box and includes a plugin ecosystem that simplifies adding advanced functionalities with minimal code in a short amount of time. Whether you need 2FA, multi-tenant support, or other complex features, it lets you focus on building your actual application instead of reinventing the wheel.
Why Better Auth
Authentication in the TypeScript ecosystem is a half-solved problem. Other open-source libraries often require a lot of additional code for anything beyond basic authentication. Rather than just pushing third-party services as the solution, I believe we can do better as a community—hence, Better Auth.
