openai/gpt-chat-latest → A (20:1)

Commit A introduces a major new subsystem and significantly changes project behavior. It replaces GitHub API-based commit discovery with deterministic multi-repository Git discovery, adds immutable discovery snapshots and a new event type, implements repository mirroring, reachability analysis, patch-identity deduplication, replayable attribution, locking and concurrency control, integrates discovery into the emission pipeline, improves ranking robustness and emission accounting, fixes halvening computation scalability, and adds extensive integration, unit, and stateful property tests. It also updates dependencies to support this functionality. Commit B is primarily a CLI and documentation refactor: it restructures commands (especially forum/post workflows), updates help text and guides, adjusts RPC hints, and updates integration tests to match the new interface. While useful for usability and consistency, it is largely an interface reshaping rather than introducing substantial new system capabilities.
