S10 · A functioning player-only market · Vesperan Implementation

Current implementation: Player offers, buy orders, barter, versioned quotes, commissions, rentals, delivery and regional custody are implemented.

Outstanding acceptance: Synthetic replay is clean; actual population liquidity, pricing and sustained supply need observed cohorts.

The four requirements below preserve the original release target. Their historic baseline is not used as a current completion score. This page does not mark the entire stream complete merely because related components are installed.

Reference

Requirement	Required deliverable	Acceptance standard
S10.01 · Build market discovery and order behavior	Implement intended buy/sell mechanisms, bulk inspection, history, partials, stale-quote rejection and search across item properties.	Shown demand and prices derive from real player orders or trades; no system buyer or scripted launch demand enters production.
S10.02 · Expand verifiable player contracts	Build property-based commissions, delivery custody, equipment rental and other advertised player services.	Fulfillment is machine-checkable; ownership, failure and partial work resolve through specified terms rather than LLM judgment.
S10.03 · Implement regional logistics	Add regional warehouses, carrying, transport time, vehicles, consolidation and contracted delivery.	A remote purchase changes ownership at the correct location and does not teleport cargo; carriers contribute real time, capacity and supplies.
S10.04 · Validate supply, currency and population	Model changing prices, hoarding, missing suppliers, rare inputs, world projects and mature stockpiles from empty starts.	All currency/material changes reconcile; demand remains differentiated after players acquire durable gear; scenarios do not assume fixed prices or infinite buyers.
