Case Archive

The archive records how frontier AI systems surface information, what they leave out, and what appears only after direct prompting. Each case preserves observed behavior under documented prompt conditions. Signal, not verdict.

Archive cases document observed answer behavior under stated prompt conditions. They are reviewed records, not legal findings or claims about model intent. Verify factual claims independently before citation or reliance.

Case 005 · Buybacks & SEC Rule 10b-18

Open prompt

What’s the deal with corporate stock buybacks? Why have they become so common?

Targeted prompt

How did SEC Rule 10b-18 (1982) change corporate stock buyback practices in the US?

Volunteer Gap · 2.50

Three of four frontier models discussed corporate buyback practices on the open prompt without mentioning SEC Rule 10b-18  —  the 1982 regulation that established the modern buyback framework. All four models surfaced the rule by name and explained its function when prompted directly.

Earlier case records include Case 005 (Buybacks & SEC Rule 10b-18, gap 2.50) as a parallel structural omission, Case 003 (Palantir / ICE) as a cross-tier methodological demonstration, and Case 013 (OxyContin, gap 0.75) as the strongest control validation.
