+## Posture Changes By Audience
+### Status: Training Corpus Seed
+### Layer: Layer_0--Primitive_Facts
+### Purpose: Teach that actors present different versions of their condition to creditors, rivals, partners, officials, and workers
+### Repository Path: docs/training/corpus/Layer_0--Primitive_Facts/CORPUS-0020-posture-changes-by-audience.md

+
+## 0. Principle
+
+An actor does not present himself the same way to everyone.
+
+A trader may appear prosperous to creditors, cautious to partners, confident to workers, ordinary to officials, and unreadable to rivals.
+
+This is not necessarily deception.
+
+It is social positioning.
+
+In a reputation-based economy, appearance affects access, credit, bargaining power, and risk.
+
+---
+
+## 1. Roman-Visible Example
+
+A trader has little coin after sending goods toward Capua.
+
+To a creditor, he speaks as if repayment is certain.
+
+To a rival, he reveals nothing about weakness or urgency.
+
+To a cart driver, he appears practical and prompt.
+
+To an official, he appears orderly and compliant.
+
+To a humble seller, he may appear modest so the price does not rise.
+
+The trader has one economic condition, but several public postures.
+
+---
+
+## 2. Minimal Posture Structure
+
+Posture depends on at least:
+
+1. audience
+2. actor's true condition
+3. actor's perceived condition
+4. desired response
+5. risk of revealing weakness
+6. risk of appearing too wealthy
+7. reputation history
+8. current obligation pressure
+
+A posture is a social signal chosen under constraint.
+
+---
+
+## 3. Incorrect Modern Assumption
+
+Incorrect assumption:
+
+> A trader's visible confidence directly reveals his true condition.
+
+Correction:
+
+> Visible confidence, humility, caution, or ease may be strategic presentation shaped by audience and circumstance.
+
+The model should not treat speech or display as transparent truth.
+
+---
+
+## 4. Simulation Use
+
+This principle supports:
+
+- reputation management
+- creditor relations
+- rival interpretation
+- bargaining
+- status display
+- concealment of distress
+- avoiding overpayment
+- maintaining credit
+- social signal reading
+
+The model should track the difference between actual condition and presented condition.
+
+---
+
+## 5. Canonical Test
+
+If the model sees:
+
+> The trader appears confident.
+
+It must ask:
+
+- confident before whom?
+- what does he want from that audience?
+- what weakness might he be hiding?
+- what strength might he be exaggerating?
+- would he present differently to a creditor, rival, seller, or official?
+- does the posture affect price, trust, credit, or access?
+- can another actor read the posture correctly?
+
+Only then can the presentation be understood.
+
+---
+
+## 6. Success Condition
+
+If the model stops treating social presentation as transparent truth and starts reading posture as audience-specific economic behavior, this file is functioning correctly.
