Who this entry is for — The chapters teach the craft; the appendices show why it is legitimate. This is the part of the book written for those who want the proofs: six technical dossiers, from the great 44-year spectrum to curve fitting. This is the annotated index.

The six appendices
| # | Title | In one line | Entry |
|---|---|---|---|
| I | The Not-to-Be-Expected "Order" | The 1921–1965 spectrum: line structure, the a = k/ω law, the comb filters | The DJIA spectrum, 44 years |
| II | Extension to Individual Issues | Dow ≡ S&P 500 to the finest detail → the signature holds for ≥¼ of issues | Commonality generalized |
| III | Transaction Interval Effects | 300 stocks: the 10–20 week "knee" and compounding's role | The transaction interval |
| IV | Response of a Centered MA | aᵣ = (1+2f)/n: half-span lag, zero at the span, constant −0.23 lobe | How a moving average responds |
| V | Parabolic Interpolation | One parabola per triple: filters at different spacings on a common grid | Parabolic interpolation |
| VI | Trigonometric Curve Fitting | Prony: frequency, amplitude and phase measured objectively | Trigonometric curve fitting |
How to read them
In plain words — Two appendices are theses (I and II: the order exists, and holds for most of the list), one is a motive (III: why shorten the interval), three are tools (IV, V, VI: the kit for anyone who wants to redo the maths).
The natural path: first Appendix I — which holds the book's deepest result, the equality of every cycle's maximum rate of change (the state table's justification) — then Appendix II, which generalizes it. Appendix III you have already met in Ch. 1: it is the arithmetic foundation of the operating philosophy. The last three accompany Ch. 11: IV explains the tool you use every day, V and VI close the spectral-research pipeline.
