metrale-scheduler

Path: crates/scheduler/

The scheduler's I/O contract (SBIO). The core, in metrale-server, decides; everything it decides about a device is a StepPlan or an Effect, handed to a DeviceIo. The clock is a ClockIo and swap files a SpillIo; driver::run is the one loop every router runs under. The crate names no model type — the sequence state and the device logits handle are type parameters, which is the compile-time proof that the contract is model-free. ScriptedDeviceIo answers the decode lane from a script, so a test can drive the real core with no model of its own.
