openai/gpt-chat-latest → A (3:2)

Commit A makes a substantial architectural change to the server. It removes the temporary demo counter feature, introduces a dedicated asynchronous settlement worker that batches vote processing, separates ranking computation from cached ranking reads, warms the ranking cache at startup, changes locking from write to read on rendering paths, and updates state management and tests accordingly. These changes improve performance, concurrency, and the overall design of the application rather than just removing dead code. Commit B is also significant, adding deterministic typed block tokens, prose item-reference tokenization, support for linkifying raw URL references while avoiding code fences, stricter DSL parsing for braced item bodies, breadcrumb fixes, and extensive tests. It meaningfully improves parsing correctness and user-facing linkification. Both commits are valuable, but A has broader impact on core runtime behavior and application architecture, whereas B is primarily focused on DSL parsing and rendering correctness.
