Two-Layer Architecture
The structural foundation of the AI-native operating rhythm. A continuous sensing layer (four streams running all the time) sits beneath a rhythmic coherence layer (five tiers running on cadence). Decisions happen in the sensing layer at the speed of signal; the coherence layer checks whether the pile of fast decisions still coheres with the intent above it. The two layers communicate through coherence questions only. Separating them is what makes it possible to be both fast and coherent at the same time. (Strategy as Infrastructure, Chs 10, 15)
Why it matters
The two-layer architecture is the category-defining structural claim in Strategy as Infrastructure. It replaces the old ‘Strategy Execution Loop’ concept (now deprecated) with a more precise model: execution is continuous (sensing layer), coherence is rhythmic (coherence layer), and the two communicate through a single disciplined channel (coherence questions). Most strategy tools and frameworks conflate execution and review into the same process; the two-layer model separates them by design.
