openai/gpt-chat-latest → A (3:2)

Side A makes a targeted behavioral cleanup by removing a redundant zero-ratio early return that is already enforced by earlier validation, preserving negative clamping and updating the test to reflect the intended semantics (items and pairs are still registered while zero-weight edges are skipped). Side B adds several new files (Dockerfile, Fly config, event log and view store modules), but the patch shows no integration with the existing codebase, so much of its lasting impact is uncertain from the diff alone.
