Principlev1
Every task must decompose to the level where done-state is
Every task must decompose to the level where done-state is clear, no clarification is needed, and completion fits in a single focused session.
Why This Is a Principle
Derives from Working Memory Capacity Limit (working memory limits prevent holding complex multi-part instructions) and Human memory under stress and cognitive load is unreliable (memory under load is unreliable for execution). The 8/80 hour rule and 'physical, visible action' requirement are concrete operationalizations of reaching the leaf level where cognitive load enables reliable execution.
