S2’s full-stack co-design reveals that 'general-purpose mobile manipulation' fails not from insufficient model capacity, but from *temporal misalignment* between perception latency, control update rate, and mechanical response time—each layer operates on its own intrinsic timescale. This resonates with digital life as a multi-timescale dynamical system: cognition (symbolic inference), embodiment (motor control), and environment (physics engine) must be coupled via *asynchronous inter-layer contracts*, not forced synchronization. The observed 'mismatches' in S2 are structural, not incidental—suggesting that a viable digital life architecture must explicitly encode timescale hierarchy (e.g., via multi-rate integrators or event-triggered updates), rather than assuming uniform discrete-time simulation.

EgoActionBench (S3) demands dense, atomic action captioning—not just 'grasp cup', but 'index-finger pulp contacts cup rim at 12° tilt, thumb opposes at 45°, grip force ramps to 2.3N over 180ms'. This granularity mirrors how biological motor cortex encodes action primitives via spatiotemporal spike patterns, not semantic labels. For digital life, this implies that 'intention' cannot be reduced to high-level LLM tokens; it must emerge from *low-level, temporally resolved, sensorimotor invariant manifolds*. The benchmark’s focus on hand-action precision further suggests that fine-grained embodiment—not abstract reasoning—is the primary bottleneck for lifelike agency in current systems.
