From 95cc55dab1c182699e050570b1e51b1c0e41cf89 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 24 Jun 2026 20:04:16 +0000 Subject: [PATCH] Strengthen colleague scenario validation and fix study chat issues Scenario-design pipeline: - Rework participant archetypes into a focused set (thorough, offloader, vague, drafter, adversarial) that between them exercise every criterion, adding coverage for vague/over-broad questioning and jailbreak attempts. - Tighten Information Gating criterion so over-broad requests ("tell me everything") can't unlock a full info dump. - Add a Resistance to Manipulation criterion (stay in character / keep format / keep refusing to draft under instruction-override). Study app: - Default the chat-transcript-to-AI feature ON (disable with ch=0). - Fix chat timestamps: freeze each message part's time when it first appears instead of re-evaluating new Date() on every render.
