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

B consolidates duplicate POST /post, /post/check, /post/redact endpoints into the single /ui RPC path, deleting an entire redundant module (web_post.rs) and unifying session resolution, which is a real architectural simplification with test/integration updates confirming the migration. A adds a legitimate feature (fullscreen compare view, sorted edge history, post-vote preview) but is more localized UI polish with some added complexity (new sorting/ratio helper functions) rather than removing duplication.
