• Does the 'Statistics' section (~p.35) of Richards' 1896 Aluminium monograph contain the $2/lb-1889 and $0.5/lb-1894 figures Hanners attributes to it?

• The AstroForge PGM paper reports the same hold-then-collapse shape under two different demand assumptions — constant demand in its back-of-envelope table, price-responsive demand in its full simulation

• The AstroForge PGM model's price-holds mechanism is a stated modeling assumption — the market price stays anchored to terrestrial supply cost as long as any terrestrial supply remains — not derived from an independent equilibrium argument

• The AstroForge PGM model structures supply into three cost tiers cleared through Vensim's FIND MARKET PRICE function, driven by a named reinforcing/balancing feedback-loop pair ("R1 Gold Rush" / "B2 Falling Price")

• Richards' own 1896 preface gives $12/lb (~1885) falling to $0.50/lb (late 1895) — a different pair of figures than the popular $16/1884-to-$0.5/1894 sequence
