The 2026-04-19 Hermes Agent Use Cases run had a Nate Herk YouTube video titled "I Tested Claude's New Managed Agents" score 51 and rank #2 with zero Hermes content. The reranker had intent-specific scoring hints but no entity-grounding check, so topic-vicinity matches (one offhand OpenClaw mention) drifted to the top. Add _primary_entity(topic) that strips intent-modifier suffixes ("use cases", "workflows", etc.) so "Hermes Agent use cases" yields primary_entity="Hermes Agent". Pass the entity through to both the LLM and fallback scoring paths. Fallback path: if primary_entity is not found (case-insensitive) in title + snippet, subtract ENTITY_MISS_PENALTY (25 pts). Skip the demotion for candidates with no text at all (image-only TikToks etc.) to avoid false negatives on thin-text sources. LLM path: add a "Primary entity grounding" hint to _build_prompt when primary_entity is non-empty. Instructs the LLM to score candidates without the entity at <=30. Tests: 24 rerank tests pass, including 8 new entity-grounding tests.
