+
+These tests expose production bugs discovered in live runs:
+1. ResonanceEvaluator crashes on truncated VLM JSON (NoneType.get) ✅ FIXED
+2. ScreenMemoryDB stores wrong classification → self-reinforcing hallucination ✅ FIXED
+3. SpatialEngine accepts semantically mismatched VLM selection (tracking)
+4. ActionMemory VLM verification treats non-YES/NO JSON as hard failure ✅ FIXED
+5. persona_interests always empty → VLM evaluates blindly
+6. Resonance scoring ignores VLM should_like → always 0.50
+7. Follow blocked on reels/explore due to action string mismatch
+
+Each test MUST fail (RED) before any production code is touched.
