Track; not yet

Why: zNAND-O is a trade-show mock-up with no published metric of any kind and no availability date, and its vendor names manufacturing complexity, cost and ecosystem adoption as unsolved. There is nothing measurable to evaluate, integrate or buy, so the only rational posture is a dated re-check trigger rather than a pilot.
Next: Set a review trigger for the next Samsung Memory Tech Day or FMS 2027: re-open only when a sample-availability or mass-production date exists AND Samsung or a third party publishes read/write latency, sustained bandwidth and $/GB for a shipping four- or eight-layer zNAND-O part. Do no design or procurement work against zNAND-O before then; for edge-AI I/O needs today, evaluate shipping PCIe Gen5/Gen6 datacenter SSDs already in the register.
