The brief, in short:

Build small-sided soccer in this project: 1v1 up to 4v4 on an authoritative room server, with a separate solo practice mode. FIFA-inspired broadcast camera and controls: move, sprint, assisted pass, charged shot, chip, standing tackle. Dribbling should be physical, with the ball actually rolling off the player's feet. Two halves, a change of ends, restarts, and a rematch vote.

The agent's first move was to take a checkpoint called Before soccer demo, then clear the starter content. It then wrote five Lua scripts: the authority match rules (roster, possession, kicks, scoring, the clock, halftime and restarts), a predicted player controller, a browser-side presentation script, a per-player marker, and the HUD.

• Player models and soccer motion clips (jog, ready, pass contact, chip) came from the Mixamo library, prepared with small glTF Transform tools into compact team-coloured GLBs. The match ball and the stadium crowd are generated by scripts in the workspace.
• Every intent (pass, shoot with a power value, chip, tackle, ready, rematch) is a declared multiplayer action. The scene script checks who sent it, the match phase, distance to the ball and cooldowns before it does anything.
• Dribbling was tuned against recorded physics runs: before, after, and a dedicated dribble recording are kept as regression evidence.

It tested the match rules with Wasmoon and mocked object APIs, ran the real physics simulation to catch an opponent being launched into the air on contact (then fixed the collision filtering), and ran the publish check before each of the four releases. The QA record separates what rule tests prove from what only a real room with signed-in players can prove.
