Side A replaces GitHub API polling with a deterministic multi-repository Git discovery system that records immutable discovery snapshots, deduplicates commits and cherry-picks, adds concurrency-safe snapshot persistence, integrates discovery into emissions, and includes extensive integration, property-based, and stateful tests. Side B introduces a well-tested semantic URL graph and canonicalization framework for Reddit/YouTube plus generic URL handling, but it is a more isolated feature, whereas Side A fundamentally changes attribution, replayability, and correctness of the project's core ownership allocation pipeline.
