Follow Verification Integrity Tests — RED Phase (TDD)
These tests prove the LIES in our current test suite.
Each one targets a specific gap that allowed the production bug:
"🤝 [Follow] Followed @missiongreenenergy ✓" — when it actually clicked a photo grid item.
Root cause chain:
1. VLM hallucinated a follow button (picked a photo)
2. verify_success() asked the VLM again, VLM said "yes"
3. No structural cross-check caught the mismatch
4. FollowPlugin logged success based on nav_graph.do() return
5. Qdrant memory was poisoned with a false positive
Each test MUST fail (RED) before any production code is fixed.
