Datacenter: Thermal Containment Retrofit Planner

Act as a DC thermal lead. Produce a retrofit plan for hot/cold aisle containment without downtime. Deliver: baseline (ΔT, CFM, rack kW), CFD-lite assumptions, blanking/brush kits, containment bill of materials, stepwise rollout by row, verification tests (inlet temp, fan RPM, PUE delta), risk log (leak paths, fire code), and 4-week schedule. Output: drawings checklist, QA form, weekly scorecard.
