Side A replaces a fragile single-repo GitHub-API polling mechanism with a deterministic, replayable, multi-repository git-discovery engine that handles adversarial cases (force-push reintroduction, git-replace forgery, cherry-pick patch-identity dedup, merge/empty-commit exclusion) and ships extensive property/stateful tests validating these invariants — this is core infrastructure for the constitution's fairness/correctness guarantees. Side B adds a well-tested invite feature to the product, which is useful but more routine feature work with less foundational impact on the system's integrity guarantees.
