+## Ownership, Use, And Income Can Separate
+### Status: Training Corpus Seed
+### Layer: Layer_0--Primitive_Facts
+### Purpose: Teach that owning an asset, using it, controlling it, earning from it, and claiming against it may belong to different actors
+### Repository Path: docs/training/corpus/Layer_0--Primitive_Facts/CORPUS-0023-ownership-use-and-income-can-separate.md

+
+## 0. Principle
+
+Ownership, use, income, custody, and claim are not always held by the same person.
+
+One actor may own an asset.
+
+Another may use it.
+
+Another may collect income from it.
+
+Another may hold a claim against it.
+
+Another may control access to it in practice.
+
+The model must not assume that possession, ownership, and economic benefit are the same condition.
+
+---
+
+## 1. Roman-Visible Example
+
+A building in Ostia may involve several different economic positions:
+
+- one family owns the building
+- a shopkeeper rents the front room
+- a warehouse clerk controls access to stored goods
+- tenants pay rent for upper rooms
+- a creditor holds a claim against future rent
+- a trader has temporary storage permission in one corner
+
+The building is one asset.
+
+The economic rights around it are several.
+
+---
+
+## 2. Minimal Separation Structure
+
+For any asset, the model should ask:
+
+1. who owns it?
+2. who possesses or occupies it?
+3. who may use it?
+4. who collects income from it?
+5. who pays upkeep?
+6. who controls access?
+7. who bears risk of damage?
+8. who has a claim against it?
+9. who can transfer or restrict use?
+10. who recognizes these arrangements?
+
+A single asset can support multiple relationships.
+
+---
+
+## 3. Incorrect Modern Assumption
+
+Incorrect assumption:
+
+> The person using an asset owns it and receives all value from it.
+
+Correction:
+
+> The user of an asset may be a renter, custodian, borrower, tenant, agent, or temporary right-holder.
+
+Likewise, the owner may not directly use the asset or receive immediate coin from it.
+
+---
+
+## 4. Simulation Use
+
+This principle supports:
+
+- rental income
+- tenancy
+- warehouse custody
+- storage rights
+- building ownership
+- land use
+- cart hire
+- ship shares
+- debt claims
+- collateral
+- agency relationships
+- maintenance obligations
+- disputes over title, use, or income
+
+The model should represent asset relationships as separable claims and roles, not as a single ownership flag.
+
+---
+
+## 5. Canonical Test
+
+If the model sees:
+
+> The trader uses warehouse space.
+
+It must ask:
+
+- does he own the warehouse?
+- is he renting the space?
+- is it temporary use?
+- who controls access?
+- who earns from the arrangement?
+- who bears damage risk?
+- who can remove him?
+- is there a creditor or prior claimant?
+- is the right recorded, witnessed, or informal?
+
+Only then can the economic position be understood.
+
+---
+
+## 6. Success Condition
+
+If the model stops collapsing ownership, use, income, custody, and claim into one state and starts tracking them as separable economic relationships, this file is functioning correctly.
