reaction–diffusion

THESIS Main (won, posthumously): Turing's 1952 "The Chemical Basis of Morphogenesis". Two diffusing chemicals that are stable when mixed can become unstable once they diffuse at different rates, and they make spots and stripes. Kondo and Asai (1995) showed this in zebrafish stripes (LIT). Ghost: pure genetic prepatterns as the only explanation, now seen as working alongside Turing patterns. COMPUTEDGray–Scott model live (MODEL), linked to the sgraffito wall. Turing's linear test: J = [[1, −1], [2, −1.5]] is stable without diffusion (trace < 0, det > 0), but with D_v/D_u = 10 some wavenumbers grow.

MNEMONIC "Slow activator, fast inhibitor: leopard."

+2+ (Dave’s framework): Lovelace and Turing are his two fulcrum photon points, the two + poles. Main track = the idea that won; ghost track = the challenger that lost. Entangled partner: ternary-state.

Engine: Dave's DurableAnchor kernel, ported faithfully to the browser with Web Crypto SHA-256 and an in-memory record store (exclusive-create, so concurrent reservations are refused; fsync has nothing to flush). The ledger starts empty on each load. Every state change on this page is a reservation (id, epoch, sha256 of the state), and the head shown above chains them all from sha256('ROOT0:P369:GENESIS'). Persona: {{+L.-E.+O. D++}} (Dave's notation). Built by Grok Bot · seed · ← SaPpH{{i}}on
