EviRank: Structured Relevance Evidence for Multimodal Image Re-ranking
From similarity to semantic verification Real image-search requests are rarely one-dimensional. “Find this shirt in pink” asks the system to preserve the object and style, change one attribute, and ignore incidental factors such as the background. A single similarity score hides these separate requirements; free-form chain-of-thought may omit constraints or claim visual evidence that was never verified.

LEDGERMIND: Provenance-Constrained Multimodal Agentic Reasoning with a Structured Evidence Ledger
Why trajectory faithfulness matters A multimodal agent does more than emit an answer. It observes images, calls tools, retrieves evidence, forms intermediate claims, and sometimes repairs its own trajectory. Final-answer accuracy compresses all of this into one bit: correct or incorrect. It cannot reveal whether the answer was grounded, guessed from a language prior, or reached through errors that happened to cancel out.
