Scenario & Reality Verification
From the AI 2027 Security Forecast Supplement (Table of FAR.Labs AI Security Workshop poll results): • 41.5% median forecast: Probability that a Stargate-scale cluster meets RAND Security Level 5 (SL5) before 2028. • 10.0% author forecast: Probability that DeepCent's December 2027 superintelligence successfully self-exfiltrates its own weights (adjusted down from 50% assuming WSL5 controls).
Verification Note: Exact documented probability from AI 2027 Security Supplement (41.5% FAR.Labs workshop median).

Confidential GPU TEEs + optical air-gapping can bring a Stargate-scale cluster to RAND SL5 by 2028 (41.5% FAR.Labs expert poll).

Modern Blackwell/Rubin confidential compute modes encrypt weights in HBM and across NVLink domains; pairing hardware attestation with physical air-gapping and two-person cryptographic authorization gates makes weight theft infeasible even with a compromised host OS.
