Solar System Simulation

The problem, in business terms

Build a numerically accurate 2D solar system simulation: real Keplerian orbital mechanics, a Newton–Raphson solver for orbital positions, hierarchical reference frames so moons orbit planets while planets orbit the Sun — deterministic, testable, and interactive.

The statement of work

A written statement of work specified the physics model, the precision requirements, the rendering, and the acceptance criteria — the same kind of document every client engagement starts from.

What the agent team did

• —A three-agent Favur team (director, implementer, reviewer) worked the statement of work end to end
• —Every change was reviewed by a separate reviewer agent before it merged
• —The physics core was built as a pure, framework-free layer so orbital math is unit-tested headlessly
• —The team verified its own output: ran the simulation, captured visual proof, ran the full test suite

What shipped

• —12 Python source modules: orbital mechanics core, reference-frame system, rendering layer
• —170 automated tests across 10 test files, all passing at delivery
• —A runnable desktop application with a documented setup (Poetry, one command to launch)
• —A README covering the physics model, design decisions, and rejected alternatives

Verify it yourself

• Open the code: the public repository on GitHub
• Watch it being built: replay the actual run
