SysML v2 Caught a Design Error Before Any Engineer Did
SysML v2 is here, and it changes what a "model" means. In this video I build a complete delivery drone model from scratch in about 40 lines of SysML v2 text, including a mass rollup, a requirement that checks itself, and a live failure the model catches before any engineer did. Then I show the model in a Git pull request and explain the standard API that lets your whole toolchain talk to it.
assume vs require in SysML v2 — who is answerable?
Two constraints on the same pump. Both about the same subject. Only one is an obligation.
I Modeled a Website. Then the Model Wrote Its Own Tests.
I've been arguing for months that if you model behavior properly, the requirements and the verification cases are already in there — you don't write them, you derive them.
Your model has one tree. Every question cuts across it.
Every model has exactly one containment hierarchy. You chose it once — usually structural — and it's arbitrary with respect to every other question anyone will ask.

One annotation. Everything else is derived.
SysML v2 annotations aren't labels. They're types.
Four keywords are the entire annotation vocabulary our SysML v2 requirement derivation reads: #exception, #observable, #precondition, #postcondition.
