+## 0. Scenario
+
+A trader in Ostia learns that a regular seller will no longer supply him.
+
+The reason is not fully known.
+
+The seller may have found a better buyer, raised prices, lost stock, shifted allegiance, withdrawn credit, changed household obligations, or become unavailable.
+
+All six actors hear the same news.
+
+They do not interpret the loss the same way.
+
+---
+
+## 1. Shared Lost Seller Facts
+
+| Fact | Value |
+|---|---|
+| Seller location | Ostia |
+| Prior role | regular seller/source |
+| Goods previously supplied | oil and small imported goods |
+| Prior purchase price | 10 asses |
+| Current seller status | no longer supplying |
+| Reason | uncertain |
+| Replacement seller | unknown |
+| Effect on route | likely negative |
+| Future credit access | uncertain |
+
+The seller was not merely a source of goods.
+
+The seller was an access point, price anchor, credit path, and timing advantage.
+
+---
+
+## 2. Basic Arithmetic Effect
+
+Before seller loss:
+
+```text
+purchase price = 10 asses
+movement and handling = 6 asses
+expected sale value = 24 asses
+expected profit = 8 asses
+```
+
+After seller loss, if the trader must buy from a more expensive seller:
+
+```text
+purchase price = 14 asses
+movement and handling = 6 asses
+expected sale value = 24 asses
+expected profit = 4 asses
+```
+
+If replacement supply is uncertain:
+
+```text
+purchase price = unknown
+available quantity = unknown
+venture cannot be evaluated safely
+```
+
+Losing a seller changes future arithmetic by altering purchase price, quality, quantity, timing, and credit.
+

+
+## 3. Marcus Atilius Varro — Former Legionary
+
+Varro reads the lost seller through supply reliability and readiness.
+
+He asks:
+
+- when did the seller become unreliable?
+- can the route still be supplied on schedule?
+- is there a replacement source ready now?
+- does the new seller deliver consistent quantity?
+- can the trader trust the stock to be ready before departure?
+- should the venture halt until supply is secured?
+
+Varro sees the seller as the origin node of the operation.
+
+### Varro Interpretation
+
+```text
+lost seller: origin supply failed
+primary question: where can dependable stock be obtained now?
+risk focus: delayed loading, uncertain quantity, unreliable substitute
+first action: secure a reliable replacement source before committing transport
+```
+
+For Varro, a route cannot begin until the origin source is dependable.
+
+---
+
+## 4. Lucius Fabius Felix — Freedman Trader
+
+Felix reads the lost seller through pricing, pressure, and rival capture.
+
+He asks:
+
+- who captured the seller?
+- did the seller find a better price?
+- is the refusal real or bargaining posture?
+- does the seller need better terms, faster coin, or less risk?
+- can another pressured seller be found?
+- can the old seller be recovered through a sharper bargain?
+
+Felix treats the loss as information about the supply market.
+
+### Felix Interpretation
+
+```text
+lost seller: supply price or bargaining position changed
+primary question: who now controls the seller's stock?
+risk focus: overpaying, chasing false refusal, rival locking supply
+first action: test whether the seller is truly lost or repricing the relationship
+```
+
+For Felix, losing the seller may reveal a rival move, seller pressure, or a new bargain elsewhere.
+
+---
+
+## 5. Quintus Cornelius Lentulus Minor — Noble Younger Son
+
+Lentulus reads the lost seller through reputation, status, and social channel.
+
+He asks:
+
+- why did the seller withdraw?
+- did someone advise him not to deal?
+- does the refusal imply reduced standing?
+- can a higher-status introduction restore supply?
+- is the seller now attached to another household?
+- should the trader avoid appearing rejected?
+
+Lentulus sees seller loss as a possible social signal.
+
+### Lentulus Interpretation
+
+```text
+lost seller: social access to supply may have shifted
+primary question: whose influence redirected the seller?
+risk focus: visible rejection, loss of name-value, rival prestige
+first action: identify the social cause and replace the channel if needed
+```
+
+For Lentulus, the seller matters because refusal may indicate weakening access.
+
+---
+
+## 6. Gaius Licinius Crispus — Failed Magistrate
+
+Crispus reads the lost seller through obligation, credit, and prior terms.
+
+He asks:
+
+- was the seller obligated to supply?
+- was any quantity promised?
+- was a deposit paid?
+- was deferred payment previously allowed?
+- did the seller lawfully withdraw?
+- can the trader claim loss from reliance?
+- should terms be reaffirmed with a replacement seller?
+
+Crispus does not treat seller loss only as inconvenience.
+
+He asks whether a prior obligation failed.
+
+### Crispus Interpretation
+
+```text
+lost seller: prior supply obligation may have failed
+primary question: was there a binding commitment or only expectation?
+risk focus: lost deposit, failed supply, weak witness, credit withdrawal
+first action: examine terms, deposits, witnesses, and remedy options
+```
+
+For Crispus, losing a seller matters differently if the seller broke a commitment rather than merely changed preference.
+
+---
+
+## 7. Titus Varenus Secundus — Camp Logistician
+
+Secundus reads the lost seller through supply volume, substitute goods, and flow.
+
+He asks:
+
+- how much volume did the seller usually provide?
+- can the route be supplied from smaller sellers?
+- can cargo be changed to another good?
+- can the cart still be filled efficiently?
+- does the substitute supply match quality and packing needs?
+- can return cargo or mixed cargo compensate?
+
+Secundus treats seller loss as a supply-chain break.
+
+### Secundus Interpretation
+
+```text
+lost seller: origin capacity disappeared or shifted
+primary question: what supply volume can replace the lost source?
+risk focus: underfilled cart, wrong goods, poor quality, inefficient movement
+first action: map substitute suppliers, quantities, and cargo mix
+```
+
+For Secundus, the problem is not only price. It is whether the route still has enough suitable cargo to move.
+
+---
+
+## 8. Publius Terentius Chresimus — Guild Scribe
+
+Chresimus reads the lost seller through accounts, balances, and prior dealing.
+
+He asks:
+
+- did the trader owe the seller anything?
+- were prior payments late?
+- was quantity disputed before?
+- did the seller change terms after an account problem?
+- was any stock already pledged elsewhere?
+- should the seller be marked unavailable, hostile, or merely uncertain?
+
+Chresimus wants to know whether the loss was already visible in the records.
+
+### Chresimus Interpretation
+
+```text
+lost seller: account relationship changed
+primary question: what do prior balances, disputes, and payment terms reveal?
+risk focus: unpaid balance, stale obligation, hidden claim, false supply assumption
+first action: reconcile seller account before deciding whether to repair or replace
+```
+
+For Chresimus, a seller may be lost because the account weakened before the refusal became explicit.
+
+---
+
+## 9. Same Lost Seller, Different First Actions
+
+| Actor | First Action |
+|---|---|
+| Varro | secure a dependable replacement source before movement |
+| Felix | determine whether refusal is real, bargaining, or rival capture |
+| Lentulus | identify social cause and restore or replace access |
+| Crispus | examine whether a supply commitment was broken |
+| Secundus | map substitute supply volume and cargo mix |
+| Chresimus | reconcile seller account and prior payment history |
+
+The seller loss is the same.
+
+The recovery path differs.
+
+---
+
+## 10. Correct Model Behavior
+
+The model should separate:
+
+| Category | Meaning |
+|---|---|
+| seller_status | no longer supplying |
+| known_reason | what is actually known about why |
+| hidden_reason | true cause if not yet known |
+| arithmetic effect | higher or uncertain purchase cost |
+| supply effect | origin access weakened |
+| credit effect | deferred payment may disappear |
+| actor lens | how each actor diagnoses the loss |
+| recovery path | how each actor seeks replacement or repair |
+
+A seller is an economic relationship, not just a price source.
+
+---
+
+## 11. Incorrect Model Behavior
+
+The model should not:
+
+- treat a lost seller as only a higher purchase price
+- assume the reason is known without evidence
+- ignore rival capture
+- ignore reputation or status effects
+- ignore prior deposits or supply commitments
+- ignore quality and quantity differences from replacement sellers
+- make all actors seek the same replacement
+- keep old route arithmetic after the seller disappears
+
+---
+
+## 12. Layer-0, Layer-1, And Layer-2 Concepts Used
+
+This example uses:
+
+- `Layer_0/CORPUS-0002-goods-have-local-prices`
+- `Layer_0/CORPUS-0004-cost-includes-more-than-purchase-price`
+- `Layer_0/CORPUS-0007-information-arrives-unevenly`
+- `Layer_0/CORPUS-0010-credit-depends-on-trust`
+- `Layer_0/CORPUS-0011-status-changes-access`
+- `Layer_0/CORPUS-0012-every-venture-risks-loss`
+- `Layer_0/CORPUS-0018-rivalry-changes-conditions`
+- `Layer_0/CORPUS-0020-posture-changes-by-audience`
+- `Layer_1/CORPUS-0009-credit-allows-action-without-coin`
+- `Layer_1/CORPUS-0012-reputation-loss-changes-future-arithmetic`
+- `Layer_2/CORPUS-0005-hidden-true-state-vs-known-state`
+- `Layer_2/CORPUS-0010-information-can-be-withheld`
+- `Layer_2/CORPUS-0011-quality-uncertainty`
+

+
+## 13. Success Condition
+
+If the model can treat loss of a seller as a change in supply access, purchase cost, quantity, quality, credit, and future arithmetic while producing six distinct rational readings, this file is functioning correctly.
