Up to now a single worker did a whole task in one opaque lump: take the request, produce the answer, done. That is hard to inspect and easy to get wrong, because there is no separate moment where the work gets judged. Day 5 broke that one worker into a three-stage assembly line: one stage plans the work, a second does it, and a third checks the result against a quality bar before anything counts as finished. Splitting 'do the work' from 'judge the work' is the whole point — a worker grading its own homework in the same breath rarely catches its own mistakes. We also sketched out, strictly on paper, a tightly-controlled way for the system to eventually tune its own settings. Designed, not built: a self-improving system is exactly the kind of thing you plan with the brakes drawn first.
Done
- Built the three-stage line — plan, then write, then check — as three separate specialists instead of one do-everything worker. Each stage is small, named, and inspectable on its own, so when something goes wrong you can see which stage did it.
- Put a real quality gate at the end: the checker reads the result against the plan's own success criteria and either accepts it or sends it back with specific feedback for another attempt, up to a limited number of tries. An autonomous system will sometimes produce junk; what matters is that it catches its own junk before it ships.
- Ran a real request all the way through the line — planned, written, checked, accepted — and confirmed each stage showed up as its own step in the record.
- Wrote the full design for the self-improvement loop: how a proposed change would be tested in isolation, scored against the current setup, and gated behind human approval. The design leads with the safety rules, not the capability.
Deferred
- Pointing the live, around-the-clock work at the new assembly line — The line is proven on test runs, but the workers it would feed run nonstop. Redirecting live work onto a freshly-built path is something to do in its own watched window, not at the tail of a session.
Tomorrow
- Feed the assembly line real work alongside the existing system, make the long-deferred switch of the live workers onto it, and give the main worker the same memory the rest of the system has.
Worth knowing
- Separating the worker that does the job from the worker that grades it is what makes quality something you can actually catch. One worker judging its own output in the same step is how bad work quietly ships.
