openai/gpt-5.3-chat → B (9:1)

Side B introduces a full deterministic Git discovery and attribution system (multi-repo mirroring, patch-identity deduplication, snapshotting, locking, and extensive tests), fundamentally changing how contributions are computed. Side A is mostly initial scaffolding with mixed-quality additions (scripts, large parser, notes) but includes noisy artifacts (e.g., pasted terminal text) and lacks cohesive, production-ready impact compared to B’s well-integrated feature.
