Gemini 3.7 Flash FSF report, p.4, p.12
“"if we cannot rule out, based on the evidence and threat models we have, that a T/CCL has been reached, we designate the model as 'cannot rule out being at the T/CCL', and mitigate accordingly" (report p.4).”

“GPT-5.6 designations: "High in Biological and Chemical", "High in Cybersecurity", "below High in AI Self-Improvement"; "these models should thus be precautionarily treated as High" (s.9, s.9.1.1).”

|---|---|---|---|
| Anthropic Anthropic Risk Report, August 2026 | “Every frontier model since Opus 4 is treated as "provisionally meeting the CB-1 threshold" "to err on the side of caution" (§4.4.2). On AI R&D: "Neither RSP criterion is met" (§3.4).” | close confidence: high | Anthropic Risk Report, August 2026 |
| OpenAI Preparedness Framework v2 / GPT-5.6 deployment safety report | “SAG options: threshold crossed; threshold not crossed; recommend a deep dive (§3.3). GPT-5.6 designations: "High in Biological and Chemical", "High in Cybersecurity", "below High in AI Self-Improvement"; "these models should thus be precautionarily treated as High" (s.9, s.9.1.1).” | exact confidence: high | OpenAI Preparedness Framework v2 |

Outcomes recorded as "No T/CCL reached" and "CBRN Uplift 1 CCL alert threshold reached" (pp.3, 12).

Pointers that are not crosswalk claims
These sources mention this concept but do not define or map it clearly enough to count as a crosswalk row — noted here so the research is visible without overstating it as a mapping.
- Frontier Model Forum
Crossing a threshold "signals entry into a new phase of heightened risk, where more rigorous risk assessments for this domain and stronger baseline safety and security measures are potentially warranted" (s3.1) — describes a consequence of status change, not a status vocabulary itself. Scored RL in the source document.

Gap
Controlled vocabulary emerging from the sources: not reached / alert threshold reached / cannot rule out (GDM) = precautionarily treated as reached (OpenAI) = provisionally met (Anthropic) = provisionally rated (Meta) / reached. The precautionary intermediate state is common to four labs under four different names — a strong candidate for a single NIKOLAI controlled-value ladder.
