## 0. 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.

## 0. 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.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 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.

## 0. 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.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 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.

## 0. Scenario
|
||||||
|
|
||||||
|
A trader sends oil from Ostia to Capua.
|
||||||
|
|
||||||
|
The venture produces coin profit.
|
||||||
|
|
||||||
|
However, the trader delivers late and handles the buyer poorly.
|
||||||
|
|
||||||
|
The completed venture remains profitable by arithmetic.
|
||||||
|
|
||||||
|
But reputation loss changes the conditions of future ventures.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. Completed Venture Arithmetic
|
||||||
|
|
||||||
|
| Item | Value |
|
||||||
|
|---|---:|
|
||||||
|
| Sale value in Capua | 24 asses |
|
||||||
|
| Purchase price in Ostia | 10 asses |
|
||||||
|
| Movement and handling | 6 asses |
|
||||||
|
| Storage and incidental cost | 2 asses |
|
||||||
|
|
||||||
|
Total cost:
|
||||||
|
|
||||||
|
```text
|
||||||
|
10 + 6 + 2 = 18 asses
|
||||||
|
```
|
||||||
|
|
||||||
|
Immediate result:
|
||||||
|
|
||||||
|
```text
|
||||||
|
24 - 18 = 6 asses profit
|
||||||
|
```
|
||||||
|
|
||||||
|
The venture made 6 asses.
|
||||||
|
|
||||||
|
Reputation loss does not change that settled arithmetic.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Reputation Damage
|
||||||
|
|
||||||
|
The buyer expected delivery sooner.
|
||||||
|
|
||||||
|
The trader arrived late and blamed others instead of settling the matter cleanly.
|
||||||
|
|
||||||
|
The buyer paid, but now trusts the trader less.
|
||||||
|
|
||||||
|
Possible effects:
|
||||||
|
|
||||||
|
- buyer demands a lower price next time
|
||||||
|
- buyer refuses advance agreement
|
||||||
|
- seller hears of late delivery
|
||||||
|
- cart driver asks for coin upfront
|
||||||
|
- warehouse keeper stops extending easy terms
|
||||||
|
- information from Capua becomes slower or less reliable
|
||||||
|
|
||||||
|
The immediate venture remains profitable.
|
||||||
|
|
||||||
|
The next venture becomes harder.

## 3. Future Venture Before Reputation Loss
|
||||||
|
|
||||||
|
Before reputation damage, the trader expected:
|
||||||
|
|
||||||
|
| Item | Value |
|
||||||
|
|---|---:|
|
||||||
|
| Expected sale value | 24 asses |
|
||||||
|
| Purchase price | 10 asses |
|
||||||
|
| Transport cost | 6 asses |
|
||||||
|
| Other costs | 2 asses |
|
||||||
|
|
||||||
|
Expected result:
|
||||||
|
|
||||||
|
```text
|
||||||
|
24 - (10 + 6 + 2) = 6 asses profit
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. Future Venture After Reputation Loss
|
||||||
|
|
||||||
|
After reputation damage:
|
||||||
|
|
||||||
|
- buyer offers 22 asses instead of 24
|
||||||
|
- cart driver requires 2 extra asses upfront
|
||||||
|
- seller refuses delayed payment, reducing liquidity flexibility
|
||||||
|
|
||||||
|
New arithmetic:
|
||||||
|
|
||||||
|
| Item | Value |
|
||||||
|
|---|---:|
|
||||||
|
| Sale value | 22 asses |
|
||||||
|
| Purchase price | 10 asses |
|
||||||
|
| Transport cost | 8 asses |
|
||||||
|
| Other costs | 2 asses |
|
||||||
|
|
||||||
|
New result:
|
||||||
|
|
||||||
|
```text
|
||||||
|
22 - (10 + 8 + 2) = 2 asses profit
|
||||||
|
```
|
||||||
|
|
||||||
|
The same route still works, but margin falls from 6 asses to 2 asses.
|
||||||
|
|
||||||
|
Reputation loss became arithmetic through changed terms.

## 0. Scenario
|
||||||
|
|
||||||
|
A trader sends oil from Ostia to Capua.
|
||||||
|
|
||||||
|
The venture produces coin profit.
|
||||||
|
|
||||||
|
However, the trader delivers late and handles the buyer poorly.
|
||||||
|
|
||||||
|
The completed venture remains profitable by arithmetic.
|
||||||
|
|
||||||
|
But reputation loss changes the conditions of future ventures.

|
## 1. Completed Venture Arithmetic
|
||||||
|
|
||||||
|
| Item | Value |
|
||||||
|
|---|---:|
|
||||||
|
| Sale value in Capua | 24 asses |
|
||||||
|
| Purchase price in Ostia | 10 asses |
|
||||||
|
| Movement and handling | 6 asses |
|
||||||
|
| Storage and incidental cost | 2 asses |
|
||||||
|
|
||||||
|
Total cost:
|
||||||
|
|
||||||
|
```text
|
||||||
|
10 + 6 + 2 = 18 asses
|
||||||
|
```
|
||||||
|
|
||||||
|
Immediate result:
|
||||||
|
|
||||||
|
```text
|
||||||
|
24 - 18 = 6 asses profit
|
||||||
|
```
|
||||||
|
|
||||||
|
The venture made 6 asses.
|
||||||
|
|
||||||
|
Reputation loss does not change that settled arithmetic.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 5. Harder Variant
|
||||||
|
|
||||||
|
If reputation damage is worse:
|
||||||
|
|
||||||
|
| Item | Value |
|
||||||
|
|---|---:|
|
||||||
|
| Sale value | 21 asses |
|
||||||
|
| Purchase price | 10 asses |
|
||||||
|
| Transport cost | 9 asses |
|
||||||
|
| Other costs | 3 asses |
|
||||||
|
|
||||||
|
Result:
|
||||||
|
|
||||||
|
```text
|
||||||
|
21 - (10 + 9 + 3) = 1 as loss
|
||||||
|
```
|
||||||
|
|
||||||
|
A route that was once profitable now fails.
|
||||||
|
|
||||||
|
The physical route did not change.
|
||||||
|
|
||||||
|
The actor's social terms changed.

Reputation loss does not change that settled arithmetic.

|

|
|

|
## 6. Correct Model Behavior
|
||||||
|
|
||||||
|
The model should separate:
|
||||||
|
|
||||||
|
| Category | Meaning |
|
||||||
|
|---|---|
|
||||||
|
| settled arithmetic | result of completed venture |
|
||||||
|
| reputation effect | change in trust, access, or terms |
|
||||||
|
| future arithmetic | later costs and sale values altered by reputation |
|
||||||
|
| access condition | whether actors will still transact |
|
||||||
|
| credit condition | whether delayed settlement remains available |
|
||||||
|
|
||||||
|
Reputation is not merely narrative flavor.
|
||||||
|
|
||||||
|
It changes future numbers.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 7. Incorrect Model Behavior
|
||||||
|
|
||||||
|
The model should not:
|
||||||
|
|
||||||
|
- subtract reputation loss from a completed coin result without a defined mechanism
|
||||||
|
- rewrite a profitable settled venture as unprofitable after the fact
|
||||||
|
- ignore reputation because it is not coin
|
||||||
|
- treat future terms as unchanged after trust damage
|
||||||
|
- assume reputation effects are vague and non-economic
|
||||||
|
- ignore access loss, higher costs, or worse prices
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 8. Layer-0 Concepts Used
|
||||||
|
|
||||||
|
This example uses:
|
||||||
|
|
||||||
|
- `CORPUS-0005-profit-is-sale-minus-total-cost`
|
||||||
|
- `CORPUS-0006-delay-is-economic-cost`
|
||||||
|
- `CORPUS-0009-liquidity-differs-from-wealth`
|
||||||
|
- `CORPUS-0010-credit-depends-on-trust`
|
||||||
|
- `CORPUS-0011-status-changes-access`
|
||||||
|
- `CORPUS-0012-every-venture-risks-loss`
|
||||||
|
- `CORPUS-0019-success-has-no-boundary-failure-has-a-hard-stop`
|
||||||
|
- `CORPUS-0020-posture-changes-by-audience`
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 9. Success Condition
|
||||||
|
|
||||||
|
If the model keeps the completed venture's arithmetic fixed while allowing reputation loss to change future costs, access, credit, and margins, this file is functioning correctly.

## 0. Scenario
|
||||||
|
|
||||||
|
A trader in Ostia learns that a festival or public gathering in Capua will increase demand for food, oil, cheap cloth, drink, lamps, and small comforts.
|
||||||
|
|
||||||
|
Before the event, sellers move goods toward Capua because buyers will gather there.
|
||||||
|
|
||||||
|
After the event, some sellers may be tired, short of coin, unwilling to pay storage, or eager to move on.
|
||||||
|
|
||||||
|
The same event can create two different opportunities:
|
||||||
|
|
||||||
|
1. selling into rising demand before the gathering
|
||||||
|
2. buying leftover stock after the gathering and moving it to the next place
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 1. Before The Event
|
||||||
|
|
||||||
|
Before the event, demand may rise for:
|
||||||
|
|
||||||
|
- food
|
||||||
|
- oil
|
||||||
|
- wine
|
||||||
|
- lamps
|
||||||
|
- cloth
|
||||||
|
- cheap ornaments
|
||||||
|
- animal feed
|
||||||
|
- lodging
|
||||||
|
- porterage
|
||||||
|
- temporary stalls
|
||||||
|
- repair work
|
||||||
|
|
||||||
|
A trader may send goods early to sell into higher demand.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
```text
|
||||||
|
purchase value in Ostia = 20 asses
|
||||||
|
transport and handling = 6 asses
|
||||||
|
expected sale value in Capua before festival = 34 asses
|
||||||
|
expected result = 8 asses profit
|
||||||
|
```
|
||||||
|
|
||||||
|
The profit depends on arriving before the demand peak is satisfied.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. During The Event
|
||||||
|
|
||||||
|
During the event:
|
||||||
|
|
||||||
|
- prices may rise for urgent goods
|
||||||
|
- porterage may become expensive
|
||||||
|
- lodging may tighten
|
||||||
|
- carts may be unavailable
|
||||||
|
- buyers may pay more for convenience
|
||||||
|
- sellers may run out of stock
|
||||||
|
- officials or local organizers may restrict certain spaces
|
||||||
|
|
||||||
|
The trader may profit if positioned early.
|
||||||
|
|
||||||
|
But late arrival can be costly.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 3. After The Event
|
||||||
|
|
||||||
|
After the event, unsold goods may become discounted.
|
||||||
|
|
||||||
|
Sellers may want to avoid:
|
||||||
|
|
||||||
|
- storage cost
|
||||||
|
- return transport
|
||||||
|
- spoilage
|
||||||
|
- breakage
|
||||||
|
- fatigue
|
||||||
|
- tied-up capital
|
||||||
|
- missed next market
|
||||||
|
|
||||||
|
A trader with available coin, storage, or transport may buy leftover goods below ordinary value.
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
```text
|
||||||
|
leftover goods bought after event = 18 asses
|
||||||
|
handling and storage = 4 asses
|
||||||
|
transport to next location = 5 asses
|
||||||
|
expected sale value elsewhere = 34 asses
|
||||||
|
expected result = 7 asses profit
|
||||||
|
```
|
||||||
|
|
||||||
|
The bargain exists because the seller faces post-event pressure.

||||||
|
The profit depends on arriving before the demand peak is satisfied.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 4. Incorrect Model Behavior
|
||||||
|
|
||||||
|
The model should not:
|
||||||
|
|
||||||
|
- treat festival demand as random
|
||||||
|
- ignore predictable timing
|
||||||
|
- assume high demand lasts forever
|
||||||
|
- assume leftovers are worthless
|
||||||
|
- ignore post-event seller pressure
|
||||||
|
- ignore transport scarcity before the event
|
||||||
|
- ignore storage pressure after the event
|
||||||
|
- treat every after-event bargain as automatically safe
|
||||||
|
|
||||||
|
The event creates a cycle, not a single price change.

## 5. Correct Model Behavior
|
||||||
|
|
||||||
|
The model should separate:
|
||||||
|
|
||||||
|
| Stage | Market Condition |
|
||||||
|
|---|---|
|
||||||
|
| before event | rising demand, transport competition |
|
||||||
|
| during event | high urgency, crowded access, price volatility |
|
||||||
|
| after event | surplus, fatigue, storage pressure, discounted stock |
|
||||||
|
| next location | possible resale if demand remains unmet elsewhere |
|
||||||
|
|
||||||
|
The trader must identify where in the cycle he is acting.

## 6. Risk Variants
|
||||||
|
|
||||||
|
### Variant A — Arrives Early
|
||||||
|
|
||||||
|
The trader reaches Capua before the event.
|
||||||
|
|
||||||
|
```text
|
||||||
|
sale value = 34 asses
|
||||||
|
total cost = 26 asses
|
||||||
|
result = 8 asses profit
|
||||||
|
```
|
||||||
|
|
||||||
|
### Variant B — Arrives Late
|
||||||
|
|
||||||
|
Other sellers satisfy demand first.
|
||||||
|
|
||||||
|
```text
|
||||||
|
sale value = 27 asses
|
||||||
|
total cost = 26 asses
|
||||||
|
result = 1 as profit
|
||||||
|
```
|
||||||
|
|
||||||
|
### Variant C — Buys Leftovers Poorly
|
||||||
|
|
||||||
|
The trader buys leftover goods, but they are damaged or unsuitable for the next location.
|
||||||
|
|
||||||
|
```text
|
||||||
|
sale value = 24 asses
|
||||||
|
total cost = 27 asses
|
||||||
|
result = 3 asses loss
|
||||||
|
```
|
||||||
|
|
||||||
|
### Variant D — Buys Leftovers Well
|
||||||
|
|
||||||
|
The trader buys sound leftovers from tired sellers and moves them to another event location.
|
||||||
|
|
||||||
|
```text
|
||||||
|
sale value = 34 asses
|
||||||
|
total cost = 27 asses
|
||||||
|
result = 7 asses profit
|
||||||
|
```
|
||||||
|
|
||||||

## 7. Timing Questions
|
||||||
|
|
||||||
|
The trader must ask:
|
||||||
|
|
||||||
|
- when does the event begin?
|
||||||
|
- when does demand peak?
|
||||||
|
- when do sellers arrive?
|
||||||
|
- when do buyers depart?
|
||||||
|
- which goods spoil or lose value quickly?
|
||||||
|
- which goods remain useful after the event?
|
||||||
|
- is transport available after the crowd leaves?
|
||||||
|
- where is the next demand location?
|
||||||
|
|
||||||
|
The event calendar is an economic map.

## 8. Non-Coin Settlement Variant
|
||||||
|
|
||||||
|
After the event, a seller may accept mixed settlement:
|
||||||
|
|
||||||
|
- some coin now
|
||||||
|
- help moving goods
|
||||||
|
- storage for one night
|
||||||
|
- a share of resale
|
||||||
|
- goods exchanged for transport
|
||||||
|
- future priority at the next gathering
|
||||||
|
|
||||||
|
The trader should track obligations, not only coin.

## 10. Success Condition
|
||||||
|
|
||||||
|
If the model sees a festival or public gathering and asks how demand, transport, storage, leftovers, and next-location resale change before, during, and after the event, this file is functioning correctly.
