Scenario - -A trader in Ostia wants to send goods to Capua. - -A cart from Capua has already arrived in Ostia carrying raw material. - -The cart must return to Capua. - -If the trader can load the return trip, the cart owner avoids travelling empty, and the trader may obtain better terms. - -The same physical journey can carry value in both directions. - ---- - -## 1. One-Way Assumption - -A weak model may treat transport as a simple one-way purchase: - -```text -Ostia -> Capua cart hire = 10 asses -``` - -If the trader must pay the whole hire, the cost may erase profit. - -But if the cart already needs to return to Capua, the trader may only need to pay for unused return capacity. - -The cart's prior movement matters. - ---- - -## 2. Known Facts - -| Fact | Value | -|---|---:| -| Cart origin | Capua | -| Cart current location | Ostia | -| Cart must return to Capua | yes | -| Normal one-way hire Ostia -> Capua | 10 asses | -| Reduced return-leg rate | 5 asses | -| Trader's cargo value in Ostia | 20 asses | -| Expected sale value in Capua | 32 asses | -| Other handling costs | 3 asses | - ---- - -## 3. One-Way Calculation - -If the trader pays full one-way hire: - -```text -purchase value: 20 asses -cart hire: 10 asses -other handling: 3 asses ------------------------------- -total cost: 33 asses -sale value: 32 asses -result: 1 as loss -``` - -The venture fails by arithmetic. - ---- - -## 4. Return-Leg Calculation - -If the trader uses the cart's required return trip: - -```text -purchase value: 20 asses -return-leg rate: 5 asses -other handling: 3 asses ------------------------------- -total cost: 28 asses -sale value: 32 asses -result: 4 asses profit -``` - -The same cargo and destination become viable because transport capacity was already moving. - ---- - -## 5. Why The Cart Owner Accepts - -The cart owner may accept the reduced return-leg rate because: - -- the cart must return to Capua anyway -- empty return earns nothing -- the load offsets animal feed and driver time -- the trader pays promptly -- the trader may offer repeat business -- the cargo is easy to handle - -The reduced rate is not generosity. - -It is shared use of existing movement. - ---- - -## 6. Round-Trip Exchange Variant - -The arrangement may include value in both directions: - -### Capua -> Ostia - -The cart brings: - -- raw timber -- wool -- charcoal -- agricultural goods -- workshop material - -### Ostia -> Capua - -The cart returns with: - -- oil -- imported goods -- tools -- household supplies -- finished stock -- letters or documents - -Each leg may serve a different party. - -The trader may profit not by owning the cart, but by understanding that the cart should not return empty. - ---- - -## 7. Household Supply Variant - -The return cargo may not all be market cargo. - -A Capua cart owner may ask to carry supplies for his household: - -- oil -- fish sauce -- cloth -- tools -- small luxury items -- medicines or prepared goods - -These goods may partly settle the transport agreement. - -This creates a mixed exchange: - -```text -cash payment -+ goods carried for household use -+ future hauling preference -``` - -The model should not treat household supply as irrelevant. - -It can be part of the transport bargain. - ---- - -## 8. Risks Of Linked Legs - -A round-trip arrangement can fail because either leg fails. - -Risk examples: - -- inbound cargo arrives late -- cart needs repair before return -- animals are tired -- driver changes terms after arrival -- outbound cargo is not ready -- return cargo is heavier than expected -- goods for household use are disputed in value -- delay on first leg destroys profit on second leg - -A round-trip plan may reduce cost, but it increases dependency between events. - ---- - -## 9. Correct Model Behavior - -The model should ask: - -- does the cart need to return anyway? -- is return capacity empty? -- who controls the cart? -- what did the cart carry inbound? -- what can it carry outbound? -- does return cargo reduce effective transport cost? -- are cash, goods, and future obligations combined? -- what risks link the two legs? - -Transport is not only a price. - -It is moving capacity across time and direction. - ---- - -## 10. Incorrect Model Behavior - -The model should not: - -- treat every cart hire as isolated one-way cost -- ignore why the cart is already in Ostia -- ignore empty return capacity -- ignore household supply as value -- assume reduced rate is unexplained discount -- ignore linked-leg risk -- calculate each leg without considering the whole movement - ---- - -## 11. Layer-0 Concepts Used - -This example uses: - -- `CORPUS-0001-trade-requires-two-locations` -- `CORPUS-0004-cost-includes-more-than-purchase-price` -- `CORPUS-0005-profit-is-sale-minus-total-cost` -- `CORPUS-0006-delay-is-economic-cost` -- `CORPUS-0009-liquidity-differs-from-wealth` -- `CORPUS-0013-non-coin-settlement-exists` -- `CORPUS-0018-rivalry-changes-conditions` - ---- - -## 12. Success Condition - -If the model sees a cart moving between two cities and asks whether both directions can carry value before calculating transport cost, this file is functioning correctly.
