Default layer strengthened: Rubin is production evidence
4.3/5
CUDA, networking and rack integration still control the AI-factory clock; Rubin moved from roadmap to official full-production/ramp.
Action: preserve thesis, no auto-entry · Source/as-of: NVIDIA/SEC Q1 + Rubin 2026-05-31/07-21 · Assumption: ramp becomes material field use · Bear/killer: deployment slippage or ASIC scale with NVDA DC/GM weakness · Next: Q2 call
