openai/gpt-chat-latest → A (4:1)

Side A introduces substantial new functionality: an extensible external URL foundation with GitHub-specific resolution, on-demand resolver UI/actions, durable system ingests, URL normalization improvements, depth-aware garden views, cooldown handling, and extensive tests. Side B makes a sound architectural change by removing persisted Reddit payloads in favor of ephemeral cached content with TTL eviction and simplifying the event log to structural events, but its impact is narrower than the broad new capabilities and infrastructure added in Side A.
