Run it
The landing page already has the simulation running behind it. OPEN THE MARKET drops you onto the floor.
Runs are seeded with a mulberry32 generator, so the same seed and config replay the exact same session, tick for tick. That determinism is what makes the lab comparisons and the stress suite possible.
Scenario presets
Three presets on the floor reset the engine into a known configuration. Each one exists to make something specific easy to watch.
| PRESET | SETUP | WATCH FOR |
|---|---|---|
| CALM | 8 robots, 6 tasks/min, 2 chargers, normal energy, no failures | Single auctions playing out end to end. The best preset for learning the bid fan. |
| RUSH | 12 robots, 14 tasks/min, 3 chargers, normal energy | The market at full throttle: crowded aisles, fast tape, congestion heat. |
| CRISIS | 10 robots, 10 tasks/min, 2 chargers, scarce energy, a charger fails mid-run | Prices repricing the fleet in real time when capacity halves. |
Controls on the floor
Speed runs from 0.5x to 4x, and pause stops the whole market (the TICK counter in the top bar freezes with it). Overlays paint the floor: CONGESTION shows the crowding field that robots route around, TASK VALUE shows where the money is. Click a robot to open its inspector, which includes the cost breakdown from its last bid. Click a task to see the standing bids. FOLLOW locks the camera to a robot; the sound button at the bottom of the tool rail controls the voice pack.
The stress suite
The suite runs four scenarios for 30 sim-minutes each, headless, and checks the invariants that matter: no non-finite balances or positions, no robot stuck in a moving phase for more than 90 seconds, no ghost entries in charger queues, no task left open longer than 200 seconds. It exits nonzero on any failure, so it works as a CI gate.
