openai/gpt-chat-latest → B (9:1)

Side B replaces GitHub API-based commit discovery with deterministic multi-repository Git mirroring, reachability snapshots, patch-identity deduplication, replayable `GitDiscovery` ledger events, and corresponding integration/stateful tests, substantially strengthening the project's core attribution logic. Side A is a large seed commit, but it includes obvious accidental terminal transcript text embedded in source files (for example `forms.rs` and `ranking.rs` begin with shell prompt output), alongside speculative notes and a large amount of initial code, making it a much less reliable lasting contribution.
