Side A replaces a fragile GitHub-API-only discovery mechanism with a deterministic, multi-repo, replay-safe git discovery system (patch identity dedup, config digests, atomic ledger writes) backed by extensive real-git unit and stateful hypothesis tests plus updated integration tests, fixing real correctness/security gaps (e.g. git-replace spoofing, cherry-pick double-payment) in a payout-critical system. Side B adds a reasonably well-tested URL canonicalization graph for reddit/youtube, which is solid but scoped to a narrower, less foundational feature with lower stakes than the ledger/discovery core touched by A.
