PAAS — Three Lines Model
Structural separation of action, evaluation, and oversight
The Three Lines Model expresses a foundational separation within PAAS between those who execute work, those who evaluate outcomes, and those who maintain system-level integrity. This separation is structural rather than procedural: it exists regardless of individual intent or competence.
Operational actors are empowered to act within their domain without requiring prior approval. Their actions are then examined by independent evaluators who do not participate in execution, while systemic oversight ensures that neither side can redefine legitimacy retroactively.

Why This Matters
The purpose of this model is not to introduce friction, but to prevent the collapse of authority into a single line of control. Most governance failures occur when execution, judgment, and rule-setting become indistinguishable. PAAS treats this collapse as a design flaw rather than a behavioral problem.
