ADVISE: accept-with-nits

Verdict. AGX kit for lab, T4000 SOM as production ceiling. Steelman against: wait for T4000 kit — NVIDIA does not ship one. Tradeoff: first enclosure wraps a T5000 brick we may not ship.

Nits. DG-12084-001 and TDG-12271-001 still missing. Same-session author+reader.

Solid. Envelope 87 × 100 × 15.29 mm, 70/90 W, no CAN, 3×25G independent.
