Could you build this?
No A new capability-secure language with security diagnostics and a native code generation path needs compiler and language-design expertise that vibe coding cannot substitute for.
What it would actually take: The stack is a parser, type and capability checker, intermediate representation, and native backend such as LLVM or a custom codegen. The hard parts are designing sound capability semantics that actually enforce authority and building the compiler toolchain and its diagnostics. A credible version needs PL and compiler engineers and security-model review, with substantial time beyond a vibe-coding session.
