  basis: "Construction Bulletin = mature design but field counts will firm at shop-drawing stage. Hospitality typical: 25% AI/AO for control-loop tuning reserve, 15% DI/DO for status growth. Higher than minimum because guestroom FCU count is pending Q-005/Q-008 and may grow if all guestroom floors are confirmed in scope."

# Trunk topology — derived from A4 panel layout (8 panels: GF + 2F + 3F +
# Roofdeck + Basement + Plant + BOH-2F + Server-Rm-GF).
# MS/TP backbone: daisy-chained from Plant (basement) → Server Room (GF) →
# 2F (BOH+Floor) → 3F → Roofdeck. Drops to BSMT, GF.
