N9.3 — Control Leray projection and pressure commutators for near‑diagonal terms

[TOTOGT]

Goal
Show that commutators involving the Leray projector and pressure can be absorbed into the envelope framework without nonlocal, non‑summable remainders.

Checklist

• Decompose pressure/Leray commutators in the near regime.
• Prove envelope‑compatible bounds or identify the exact extra hypothesis needed.
• Provide a short note showing how these terms are absorbed into Lemma 3.1 of NS D9.
