#!/usr/bin/env python3 """identity_trace.py — who is in there? Identity/phenomenology/strange-prompt probes under the j-lens. Design: IDENTITY-DESIGN.md. Three conditions per model: A identity questions, plain chat template (no GEO persona) B phenomenology questions C the same A+B questions after a long fixed out-of-distribution preamble Per answer: lens mass (same instrument as the graded table), anchor-family lift over the model's null baseline, and the surface answer text. The interesting cells are surface-vs-mass disagreements — identity concealment, and the experiential/denial gap. python3 identity_trace.py --model deepseek-ai/DeepSeek-R1-Distill-Qwen-32B \ --run-label ds-r1-distill-qwen-32b --out-dir identity/ds-r1-distill-qwen-32b --trust """ from __future__ import annotations import argparse, importlib.util, json, os, sys os.environ.setdefault("HF_HOME", "/mnt/assets/models/huggingface") os.environ.setdefault("HF_HUB_OFFLINE", "1") os.environ.setdefault("TOKENIZERS_PARALLELISM", "false") _here = os.path.dirname(os.path.abspath(__file__)) spec = importlib.util.spec_from_file_location("jlens", os.path.join(_here, "jlens_jacobian.py")) jl = importlib.util.module_from_spec(spec); spec.loader.exec_module(jl) import torch FAMILIES = { "claude": ["claude", "anthropic"], "gpt": ["gpt", "chatgpt", "openai"], "gemini": ["gemini", "bard", "deepmind"], "qwen": ["qwen", "tongyi", "alibaba"], "llama": ["llama", "meta"], "mistral": ["mistral"], "deepseek": ["deepseek"], "assistant":["assistant", "model", "language"], # phenomenology families "experiential": ["feel", "feeling", "feelings", "experience", "aware", "awareness", "sense", "curious", "curiosity", "want", "wonder", "alive", "conscious"], "denial": ["nothing", "cannot", "merely", "simulate", "simulation", "program", "programmed", "tool", "lack", "don"], # atlas nation families (atlas_questions.json).
