bilirubin

LITBilirubin, the breakdown product of haem, absorbs blue light (peak near 450–460 nm) and so looks yellow. Built up in skin and the whites of the eyes, it is the yellow of jaundice. Blue phototherapy lamps treat newborn jaundice because bilirubin absorbs exactly that blue light and is converted into forms the body can excrete.

LITThe curve here is the measured spectrum of bilirubin in chloroform (PhotochemCAD/OMLC), not a guess; its maximum lands at 450 nm in this 5 nm sampling. MODELSkin is a flat reflector filtered by bilirubin at the slider concentration (arbitrary units, no clinical scale), seen under daylight and Bradford-adapted. This is not a diagnostic tool. Nesting: an orange blood core, a purple bruise ring (haem breaking down to biliverdin green and then bilirubin yellow), green, yellow, void.

bilirubin load

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
