What's this about?
A-JIT proposes software that combines code, a runtime harness and an embedded agent so it can observe usage traces and synthesize missing implementations or tools while running.
What exactly is “just-in-time construction”?
A traditional JIT compiler specializes machine code for what a program is doing now. A-JIT extends the analogy upward: the application itself changes workflows and logic for the current user.
Why is this worth noting?
It describes a design paradigm rather than a mature evaluated system. Continuously self-changing software also creates hard questions about reproducibility, review, rollback and security.
