-## Reputation Loss Changes Future Arithmetic
-### Status: Training Corpus Seed
-### Layer: Layer_1--Worked_Examples
-### Purpose: Teach that reputation loss does not rewrite the settled account of a completed venture, but can change the costs, access, and margins of future ventures
-### Repository Path: docs/training/corpus/Layer_1--Worked_Examples/CORPUS-0012-reputation-loss-changes-future-arithmetic.md

-## 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.
-
----
-
-## 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.
-
----
-
-## 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.
