-## Small Profit Versus Future Access
-### Status: Training Corpus Seed
-### Layer: Layer_1--Worked_Examples
-### Purpose: Teach that immediate arithmetic outcome and future strategic value must be tracked separately
-### Repository Path: docs/training/corpus/Layer_1--Worked_Examples/CORPUS-0004-small-profit-vs-future-access.md

-## 0. Scenario
-
-A trader sends oil from Ostia to Capua.
-
-The venture produces only a small coin profit.
-
-However, the buyer pays promptly and invites the trader to supply again.
-
-The immediate arithmetic outcome is small.
-
-The future access may be valuable.
-
-These are related, but they are not the same thing.
-
----
-
-## 1. Known Final Values
-
-| Item | Value |
-|---|---:|
-| Sale value in Capua | 18 asses |
-| Total cost | 17 asses |
-| Final arithmetic outcome | 1 as profit |
-
-The venture earns only 1 as.
-
-By coin arithmetic, the result is small.
-
----
-
-## 2. Additional Strategic Result
-
-The buyer in Capua is satisfied.
-
-The trader gains:
-
-- a reliable buyer contact
-- faster future negotiation
-- possible deferred payment trust
-- better information about Capua demand
-- improved chance of repeat sale
-
-These gains may matter later.
-
-They are not coin profit from the completed venture.
-
----
-
-## 3. Incorrect Model Behavior
-
-A weak model may say:
-
-> The venture was very profitable because it created a valuable relationship.
-
-This is imprecise.
-
-The correct separation is:
-
-```text
-immediate profit = 1 as
-strategic value = improved future access
-```
-
-The future access may be more important than the 1 as.
-
-But it must be recorded separately.
-
----
-
-## 4. Correct Model Behavior
-
-The model should record two outcomes:
-
-| Outcome Type | Result |
-|---|---|
-| arithmetic outcome | 1 as profit |
-| strategic outcome | buyer relationship improved |
-
-The model may then reason:
-
-- the immediate venture barely profited
-- the trader may repeat the route under better terms
-- future credit or information may improve
-- the small profit was acceptable because it created access
-
-But the model should not rewrite the arithmetic result.
-
----
-
-## 5. Variant: Rational Small Loss
-
-The same logic applies if the venture loses a small amount.
-
-| Item | Value |
-|---|---:|
-| Sale value | 16 asses |
-| Total cost | 17 asses |
-| Final arithmetic outcome | 1 as loss |
-
-If the buyer relationship becomes valuable, the venture may still have strategic value.
-
-But the immediate account remains:
-
-```text
-1 as loss
-```
-
-A strategic loss is still a loss.
-
----
-
-## 6. Why This Matters
-
-If strategic value is merged into profit, the model becomes confused.
-
-It may:
-
-- ignore arithmetic
-- call losses profitable
-- overvalue vague future benefits
-- fail to track coin depletion
-- miss hard-stop risk
-
-If strategic value is ignored, the model becomes too narrow.
-
-It may:
-
-- reject useful market-entry ventures
-- miss trust-building behavior
-- ignore future access
-- undervalue repeat buyers
-
-Both errors are harmful.
-
----
-
-## 7. Correct Accounting Separation
-
-Use separate records:
-
-```text
-coin_result: +1 as
-relationship_result: buyer_trust_up
-information_result: capua_oil_demand_known_better
-future_access_result: repeat_sale_possible
-```
-
-Do not merge all of these into one number.
-

-## 8. Layer-0 Concepts Used

-This example uses:
-
-- `CORPUS-0005-profit-is-sale-minus-total-cost`
-- `CORPUS-0006-delay-is-economic-cost`
-- `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 can say, “This venture made only 1 as, but improved future access,” without confusing the access gain with immediate profit, this file is functioning correctly.
