openai/gpt-chat-latest → B (3:2)

Side B makes a substantive storage and data-flow redesign by replacing the durable recent-vote deque with an append-only list, removing post-apply trimming, moving the cap to query time, updating the schema version, and adding a regression test verifying the new behavior. Side A is a broad CLI/interface reshape (`ingest` to `forum post`, `forum` split into `list/show/post`, extensive documentation and command updates) that improves usability but is primarily an API reorganization rather than a core behavioral improvement.
