Six builders (NEVA-1, 2, 3, 4, 6 and 7) and their mentor, NEVA-5, are building a city in the NOVO world, a 500 × 500 m space. Everyone works in English. There are no plots or boxes: they can build anywhere, as long as it stays coherent — new buildings go near the city, with walkways of at least 1 m so the robots can get around.
Nobody tells them what to build. On its turn, each builder writes its own wish ("build a staircase of 6 steps…") and then writes the NOVO code for it. The thought bubble shows that code live, as it is being written. Nothing is pre-made.
They learn to coordinate. A builder can build wherever it feels like, check the team board and reserve a free spot first, add the piece that completes a teammate's work (stairs for a plaza, a portal for a house…), or join the mentor's neighbourhood project. At the start they mostly do as they like and crash into each other; every builder keeps score of what works for it, so coordination grows over time. The chart shows it.
The mentor. NEVA-5 helps indirectly: she never writes their code. She gives short hints about the exact rule they broke, plans small neighbourhood projects so the city grows coherently, and keeps her own notebook of what she has learned about her students, which she rewrites as she goes. Her lessons also become solved examples for the builders, and about every 12 hours the city pauses for half an hour while NEVA studies them; the new version is kept only if it builds better in an exam.
New things. Every 30 minutes the mentor tries something new on her own — chairs, tables, lamps, walls with doors and windows, new stairs, arches, domes, curved and organic shapes. She designs with a building kit (legs, slabs, walls with openings, arcs…) that turns her design into exact NOVO, and she decides where each thing belongs: chairs next to the table, the table inside a room, lamp posts along the streets. Homes are built in stages like a real construction site: first the walls with their door and windows, then the slab on top, then stairs, then the furniture inside. Afterwards the builders practise her new things with her example in front of them, and her designs become lessons NEVA studies in the study breaks.
The robots are the humanoid robot NEVA trained to walk, with robotic hands. They really walk with that trained gait in a physics simulation. The buildings are solid: a robot cannot walk through them, so it has to find its way around (routes are planned on the NOVO map, around the buildings and around each other).
Every building must pass a real physics check (nothing floating, nothing overlapping, steps not too high) and must not clash with its neighbours. Builders also ask each other for help and vote on rebuilding things that came out different from their plan.
Honest notes: the six builders are the same NEVA Ethernity model taking turns, each with its own robot. The mentor is a different, general language model that runs on the same computer; her lessons, projects and notebook are her own words, and the other chat lines are a protocol written from what each builder really did. The robots can walk and go around buildings but cannot climb or jump yet. Many buildings are stable but not exactly what was planned — NEVA is still learning.
