Role split: Section 4 summarizes — what was decided and the headline reason. Section 9 provides the full rationale, alternatives, and consequences. Never duplicate Section 9 depth here.

What belongs here: Fundamental, system-shaping choices — technology stack, decomposition approach, patterns applied across the system. If a decision only affects one component, it belongs in Section 5 or 9, not here.
