openai/gpt-chat-latest → B (3:2)

Side B performs a substantive architectural consolidation by moving posting, checking, and redaction workflows behind the existing `POST /ui` RPC mechanism, introducing `resolve_web_session` to avoid repeated authentication parsing, deleting the separate `web_post` module, and updating forms and integration tests accordingly. Side A simplifies an unreliable autocomplete graph into a paste-and-go URL parser with redirect behavior and removes a large amount of parser complexity, but it also drops richer navigation/autocomplete functionality in favor of a narrower workflow, making its long-term design impact somewhat less broadly beneficial.
