~anthropic/claude-sonnet-latest → A (6:4)

Side A eliminates a duplicated web_post.rs module by unifying all /post, /post/check, /post/redact logic into a single /ui dispatcher with one shared session-resolution helper, removing ~360 lines of parallel/duplicate logic and updating tests and fixtures to match — a genuine architectural consolidation with lasting maintainability benefit. Side B is a set of narrower, real fixes (out-of-band delegate attribution, stricter vote-pool fallback, dead swap button removal, route rename) that are correct but smaller in scope and impact compared to A's structural DRY-up of the entire web ingest/check/redact pipeline.
