At the March 2026 WG21 meeting in Croydon, the ISO C++ committee completed the C++26 Standard, including the addition of *contract* assertions. This milestone is the result of a sustained effort by the authors of [[P2900R14](https://wg21.link/p2900r14)] and the WG21 subgroups responsible for evaluating the proposal: SG21, EWG, and CWG. This success was made possible in part by the existence of a clear roadmap [[P2695R1](https://wg21.link/p2695r1)] for the C++26 cycle. That roadmap was adopted by SG21 with strong consensus in 2022 and was followed throughout the entire standardisation process. The feature set included in C++26 provides a solid foundation, but lacks a number of extensions needed to support additional use cases for which there is already a demonstrated need. In particular, further work is required to make contract assertions truly usable at scale: in very large codebases, across libraries developed and distributed independently, and in specialised environments such as safety-critical systems. This is by design. WG21 has a long-established practice to standardise powerful new language features *incrementally,* and this approach has proven successful in the past, for ex
