Reproduce

How to re-run the v2 investigation end-to-end. Every script in the experiment directory uses uv run with PEP 723 inline metadata — no virtualenv, no pyproject.toml. Set OPENROUTER_API_KEY and you're ready.

  • Quickstart — minimal command sequence to reproduce the v2 main run, mixed-effects analysis, confound probes, and figures.
  • Main run — how to run preamble_quality_v2_main.py end-to-end: smoke-test slice, full run, useful flags, expected runtime, output layout.
  • Post-run analysis — how to run analysis_addendum.py (mixed-effects M0/M1/M2 + weight sensitivity) and figures.py (5 matplotlib/seaborn figures), and what each produces.
  • Confound probes — how to run confound_probes.py (post-hoc probes A/B/C distinguishing H-mechanism from H-judge-priming).
