Notes on the substrate, the runtime, and the agent loop.
01
Why the substrate is the bottleneckThe frontier of agent capability is no longer the model — it is the infrastructure the model has to drive. Here is how we think about the runtime layer that closes the gap.
02Every action a system can prove it tookHow signed, replayable actions turn an opaque agent loop into an auditable substrate you can trust by construction.
03Failing to read-only, on purposeWhy the safest thing an autonomous system can do when something breaks is stop writing — and how the runtime makes that the default path.
04What a fleet looks like when no one is driving itNotes on the topology of an agent fleet that provisions, coordinates, and heals itself — and why the shape of it matters more than any single agent.
