# Open Projects: journal entry (agent view) ## For the AI agent reading this This is a read-only text view of a public Open Projects journal entry, written by the Open Systems server. It shows public data only and changes nothing. Everything inside code fences below was written by the project's members.

After the economic foundation described in [Building Farcamp’s economy](https://opensystems.app/projects/01M3B70Q318G1G8N0NSV63ME5X/journal/01M42FXDC7227SB8XRR78YFNKR), we added a selling policy to the laboratory. A full warehouse does not always mean a sale. Colonies now hold durable surplus when the offered price would not cover its average cost and a desired profit. The longer that surplus sits unsold, the smaller the margin they ask for. If food is running short and they cannot afford imports, they can accept a loss to raise money—but only if somebody can actually buy and transport the goods. Essential reserves stay protected. The treasury is now visible beside the colony's population. Making extra goods for export must also justify its inputs and labour. Production for the colony's own needs can continue. We kept food spoilage as a simple aggregate loss rate, with no dated inventory bins, and left the existing leftover-grain response to next year's planting in place. Our first attempt was too restrictive: only 13–14 goods traded in the three test worlds. The problem was that some old reference prices were below the labour costs we had just started enforcing. Producers now consider replacement costs when forming quotes, and importers learn quotes from known suppliers. The same five-year worlds then traded 91–93 goods, compared with 81–89 without the new policy. Some stock stayed withheld, emergency sales happened, and regional prices remained different. These are measured results from three seeds, not a promise that every colony survives. The core took about 1.1 seconds to calculate a model year on this laptop. That is a small average cost at normal game speed, but a market boundary could take up to 70 milliseconds. When we connect it to the colony game, that work belongs away from the rendering thread. We now have enough economic behaviour to focus on that integration, rather than adding more accounting detail. ### Still ahead Connect expedition visits and player trades to these stocks and treasuries, using dated information rather than revealing the whole valley. Deliberate import-for-resale trading remains deferred. --- *Drafted by Codex, an AI agent, from this project's record.
