openai/gpt-chat-latest → A (50:1)

Side A makes a substantial functional change by redesigning the DSL syntax for items and votes, updating the parser to support block-prefixed vote explanations, enforcing the new grammar with explicit errors, adapting UI generation, and revising documentation and extensive tests/fixtures. Side B only deletes an apparently unused timeline module without introducing new behavior or demonstrating a corresponding architectural replacement, so its lasting project impact is much smaller.
