State Machines All the Way Down
State Machines All the Way DownApril 10, 2026In Orb, every feature is a state machine. Not a component tree, not a bag of hooks — a state machine with explicit states, guarded transitions, and a closed circuit the compiler enforces before any code is generated.
ReadExhaustive Tests That Walk the Machine
Exhaustive Tests That Walk the MachineApril 10, 2026`orb validate` proves structural properties. `orb test` goes further — it walks every edge of every state machine, fires every event from every state, and verifies that guards block and allow correctly. You write zero test code. The graph is the test plan.
ReadThe Compiler Is the Test Suite
The Compiler Is the Test SuiteApril 10, 2026`orb validate` does not just check syntax. It walks the state machine graph and proves properties that would normally require dozens of hand-written tests. Closed circuits, emission contracts, binding validity, and pattern prop requirements — all checked before any code is generated.
ReadAtoms, Molecules, and the uses System
Atoms, Molecules, and the uses SystemApril 10, 2026Orb follows atomic design for behavior, not just UI. Standard behaviors are atoms — small state machines that own their topology. Your application composes them into molecules using `uses` imports and an override surface. The atom's states and transitions stay constant. You rebind the data, rename the events, and replace the effects.
ReadMachines with Traits: How Orb Will Change the Future of Robotics
Machines with Traits: How Orb Will Change the Future of RoboticsJanuary 15, 2026Imagine a world where you don't need to write thousands of lines of code to make a robot move intelligently. A world where you declare a machine's behavior the same way you describe the motion of planets in their orbits.
