Define the multi-generation platform software architecture for current Asimov silicon and at least one materially new future architecture, specifying stable, versioned interfaces for boot, commands, memory, DMA, C2C, scheduling, telemetry, errors, reset, security, and host/device interaction. It is intentionally not buried inside a delivery team: you will maintain a cross-generation view, make durable interface decisions, and still contribute reference implementations where code is the clearest way to resolve ambiguity.
