openai/gpt-chat-latest → B (9:1)

Side B introduces a substantial evidence and audit infrastructure: it adds versioned append-only Evidence events, idempotent persistence with hash chaining, resumable LLM ranking, HTML evidence browsing, richer audit links, and extensive integration/unit tests covering replay, downloads, and legacy behavior. Side A is a useful but localized feature that threads existing view-count support into the vote comparison page and adds tests verifying the displayed count increments.
