Riedl 2510.05174 PID/TDMI as INFORMATION-LAYER in Cluster-D measurement stack. Port via numpy Williams-Beer Imin (dit unavailable) to existing archive on TWO substrate channels:
- paper3 hub-spoke (cold-start-v3, gift_engine CLEAN): predict high redundancy >0.7, low unique <0.1, low synergy <0.05 (hub broadcasts same signal → informationally redundant).
- paper7 architecture-axis (rule_multigen HIGH-confound): predict Class A (gpt4omini/haiku) unique-dominant, Class B (qwen/flashlite) redundancy-dominant. **MANDATORY engine-source-audit: paper7 PID values are CONDITIONAL on axis_per_agent (axis-hint) + INITIAL_GOALS (per-agent goal text) injection.** Any Class A/B PID gap is potentially explained by engine-driven prompt differentiation, not substrate. Verdict.md MUST tag paper7 PID profile «engine-conditional» absent control arm.
