identity_trace.py

Identity + phenomenology probes. Family lifts over a per-model null; the benign-synthetic strange prompt; the top-64 cutoff that currently underpowers condition A (named, unfixed).

class="s">"""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.
