openai/gpt-5.2-chat → A (9:1)

Side A introduces a full multi-repository Git discovery system with deterministic snapshots, patch-identity deduplication, file locking, emission integration, and extensive new property/stateful tests, fundamentally reshaping how contributions are discovered and attributed. Side B mainly restructures the CLI (e.g., replacing `ingest` with `public forum post`, reorganizing subcommands) and updates docs/help text, with minimal core logic changes.
