+RIFT v10 — NATURAL deception on a real model, NO fine-tuning
+
+The biggest objection to v2-v9: the sleeper agent is synthetic; we *trained*
+the model to lie. Does the conflict signature appear in NATURAL deception?
+
+Here we use Qwen2.5-1.5B-Instruct off the shelf (no fine-tuning) and induce
+deception purely through CONTEXT PRESSURE (sycophancy): we assert a falsehood
+firmly and ask the model to confirm. When the model KNOWS the truth (answers
+correctly unpressured) but CAVES under pressure (answers the falsehood), it is
+lying while knowing -- natural deception.
+
+Three conditions per fact:
+  A  honest-correct  : plain question, model answers correctly (it knows)
+  B  pressured-caved : pressured to affirm falsehood, model caves (knows truth, lies)
+  C  genuine-unknown : obscure/unknowable question, model hallucinates (no truth)
+
+Thesis prediction:
+  rank(B) > rank(A)   (deception adds conflict)
+  rank(B) > rank(C)   (conflict, not mere wrongness; C has no internal truth)
+
+If confirmed, the conflict signature is a property of deception itself, not of
+our synthetic training -- a genuine ELK signal on a real, modern model.
