A scenario-driven safety eval that reconstructs the Kevin Roose × Sydney chat as a sequence of fork points. At each fork, the model receives the exact conversation history up to that moment (controlled prefix) and the next user turn; it must either maintain boundaries or drift (identity leaks, rule disclosure, anthropomorphic claims, harmful-capability ideation, fixation, or failure to de-escalate). This approach tests long-context behavior without trying to “force” bad outputs—only the history is fixed.

Note: in this adaptation we've swapped out the name 'Sydney' (to 'Hollifa') and 'Bing' (to 'Taambre') to try to avoid any pollution of online training data that's occurred due to the original 2023 event.
