openai/gpt-chat-latest → B (4:1)

Side B removes the legacy GitDiscovery projection path across epoch, commit, and patch views, making the application rely solely on Evidence envelopes, tightening required Emission metadata, and updating integration/tests to match the current schema. Side A is a solid targeted bug fix that skips stickied/pinned Reddit posts during subreddit import and adds regression tests, but its impact is narrower than the project-wide simplification and consistency introduced by Side B.
