Reader reproduction instructions

Compile main.tex with its listed LaTeX packages and included figures. The
numerical solver uses numpy==2.3.5 (requirements.txt); use ordinary Python,
without -O, because historical diagnostic dependencies contain assertions.
  python -B code/solver_demo.py --output-dir /absolute/new/solver --figure-dir /absolute/new/figures
  python -B code/reproduce_diagnostics.py --solver-report /absolute/new/solver/solver_results.json --output-dir /absolute/new/diagnostics
The three Python files under provenance/ and code/independent_solver_check.py
are required executable mathematical dependencies, not narrative reviews.
New output paths must be unused. The included figure
files reproduce the manuscript's presentation; optional plot_results.py needs
reportlab. The diagnostics concern the stated finite and Fourier floating-point calculations.
  python -B code/verify_manifest.py
checks the public distribution's exact file identities only.
