The Market Tiers

Trading in the Cartographer has tiers. An actor who has grown a few carrots and wants a few coins has a different path to market than one who has spent months accumulating rare goods from across the region. Both of them can sell. The mechanisms through which they do it are different.

The blanket

The lowest point of entry is a blanket.

Any actor with something to sell can bring it to the weekly market, lay out a blanket, and trade whatever they have grown or produced at home. No cost. No commitment. One day a week. It holds as much as a blanket will hold.

For an actor with a small surplus and a light ambition, this is enough. For an actor who has turned into a serious producer, it very quickly is not.

The rented market store

Above the blanket is the rented market store. It costs money to hold, carries significantly more inventory than a blanket pitch, and is still a weekly arrangement — open on market day, closed when market day ends. An actor who rents one has moved from occasional selling to something that requires a degree of planning.

The roche

A roche is a permanent market stall. Where the rented store operates one day a week, the roche is there every day. An actor who has established a roche has moved from occasional or weekly selling into something that functions as a trade. They are a presence in the village market, not a visitor to it.

Industries and proper shops

At the top of the tier are the industries — the crafters and producers whose operations are substantial enough to constitute permanent shops. A blacksmith, a bakery, a carpentry, a mill. These are not occasional presences in the market. They are anchors of the village economy, open as a function of what they are.

The rental shop: emergent retail

Outside these tiers — or perhaps weaving across all of them — sits something more interesting.

Any actor who has accumulated enough inventory can rent a shop. The check for this is stateless: when the actor arrives with their goods, the system looks at what they have and determines what the shop will become. Not what it was, not what was planned — what it needs to be now, given this particular actor and what they have turned up with.

This is the same principle as the Agricultural Fair's self-generating classes. The shop does not have a pre-existing identity. The inventory creates it.

An actor who has spent their time travelling the map buying rare goods from other regions — never producing anything themselves, just finding and acquiring — arrives at a rented shop and it becomes a curio dealer, a rare-goods emporium, whatever form fits what they carry. Another actor has somehow ended up growing nothing but carnations for two seasons. They arrive, the system checks their inventory, and there is now a florist in the village that nobody designed.

Neither of these was written by anyone. The shop is what its inventory is.

Rules at the ground, emergence above it

It is worth naming something directly here, because it is relevant to how the Cartographer's architecture is understood.

Some things in the Cartographer need rule sets. The market tiers need rules to exist as a structure. There has to be a mechanism that distinguishes a blanket from a roche, that knows what constitutes enough inventory to trigger a rental shop, that performs the stateless check when an actor arrives with their goods. At the ground level, there are grafts. This is not a contradiction of the VINE architecture — it is what gives the architecture something to press against.

The emergence is not the absence of rules. It is what happens when rule sets are combined. A tier system, a stateless shop check, an inventory built through travel, a carnation surplus that grew beyond anyone's plan — none of these individually produces a florist. The florist is what you get when all of them are present at once, and nobody had to write a florist.
