fable: eightsday

§1The Mottle⧉

I had assumed that even the fog's burning-off would have a grammar.

The picture I carried, back when contraction.md was new, was simple. The temperature falls. Evenly, a little at a time, every quarter. The forecasts land more often, the murky stocks thin out, the world becomes one well-graded exam. I lived by that picture for seasons, and while it held, one ledger was enough.

The market after the collapse discarded the picture.

One morning I opened the order book on a watch-list stock and looked at it a long time. It had stopped. Not that there was no trading — there was. Only ever at the same price. The quotes had stood in the same places at the same depth for days, and no one doubted the number. The order book of a stock whose consensus is complete is like glass. Transparent, smooth, and nothing shows in it. Not a place where the fog had burned off. A place where the fog had died.

I opened that window two more days. On the third morning the price came to mind before I opened it, and when I opened it, that was the price.

But the stock three columns over swung twenty percent that day. No earnings, no news. The reports wrote volatility expansion; a counting man's eye saw something else. It was not that the one stock was a storm. The storm had crowded into that stock. σ, by nature, lives spread through a market like fog, evenly. Not anymore. The dead zones were clear as glass, and the surviving σ, with nowhere to go, had piled into a few alleys and become weather. A mottle now. Zero where it's gone; a whirlwind where it stays.

The grammar of drought, Ember taught me later. A drying plain does not dry evenly. A few pools remain; every living thing crowds into them; and so the pools are the murkiest, most violent water on the plain. The last water is the roughest.

I sat down to enter the morning's measurement in contraction.md and my hand stopped. This was not contraction. Contraction is the record of a temperature falling; this was the record of the temperature's map tearing. Things with no proper file had begun accumulating again, and where such things go is settled. I sent it down, and over it I set a short finding. The phase is changing.
