Worked example / The bakery price change
A story with something
real underneath.
A bakery raises its meal price. A customer keeps going there, until a visit teaches them what changed. The next time, they choose the diner.
Responsive markets / Development demonstration
A fifty-cent change.
A different next stop.
A reproducible Narrator-Off demonstration using the game’s bakery and diner offerings in a prepared trading scene.
- 01 / Sales change the price
$6.50 becomes $7.00.
Four accepted purchases bring the bakery’s meal price up one step at its review. The diner has one sale and holds at $6.50. These are published prices, not a narrator’s invented explanation.
- 02 / A visit changes what is known
The customer learns by buying.
The buyer still knows the old bakery price until a completed visit settles at $7.00. That visit teaches them the new price. Publishing it did not update everyone’s knowledge.
- 03 / Knowledge changes the next choice
Next time, the diner.
The informed buyer chooses the diner and pays $6.50. In the comparison run, the buyer who had not learned the price change still chooses the bakery. The earlier $7.00 purchase remains paid.
Reality and point of view
The price changed.
Not every mind did.
A fact can be true before someone knows it.
The bakery’s current price and a customer’s last learned price are different facts. Until the customer learns what changed, their next decision can still rest on yesterday’s information.
That is what the engine protects. Narration describes a result; it cannot give a customer a price they have not learned just because the business has published it.
Consequences across turns
The next decision starts
with what came before.
The completed purchase stays in the record, even after a later price review. In the same demonstration, saving and restoring preserved the commercial facts and the next review’s result.
Game time advances through play. Businesses and other people can change during those advances, including out of view. They do not keep running against a real-world clock while you are away from the game.
