~anthropic/claude-sonnet-latest → A (63:37)

A is a focused, well-tested feature/bugfix (deterministic block tokens, proper prose URL tokenization with fence-awareness, breadcrumb root fix) that clearly improves correctness and is validated by new unit tests. B is a sprawling 'first pass' architectural rewrite (REST endpoints collapsed into one giant RPC dispatcher, Thread→Room renaming) that deletes a lot of previously tested, well-structured code and introduces a large, less type-safe generic command enum — valuable functionality-wise but explicitly unfinished/exploratory and far noisier relative to its net design benefit.
