openai/gpt-chat-latest → A (5:1)

Commit A delivers a coherent, project-wide architectural change with clear functional impact. It removes persistent storage of Reddit payloads from the event log and entity store, introduces ephemeral projection caching with TTL-based eviction, simplifies replay by logging only structural events, updates the journal and projection pipeline, adjusts storage schema versions, and adds or updates tests to validate the new behavior. This is a significant redesign touching many core subsystems while preserving consistency. Commit B is very large in raw size, but much of it appears to be an initial dump of files, design notes, and even pasted terminal output rather than a polished, integrated feature. It mixes utility scripts, planning documents, large parser and reducer implementations, and accidental artifacts. While it contains substantial code, the commit message ('init seed') and the presence of copied terminal sessions reduce its effective contribution as a clean, production-ready change. Overall, A represents the more impactful and deliberate contribution.
