~x-ai/grok-latest → A (3:2)

A delivers integrated, lasting product behavior: deterministic typed block masking, a real prose item-ref tokenizer (with newline/punctuation and code-fence rules), stricter braced-body DSL parsing, and HTML garden linkification for ~/‑/ and raw URLs wired through external_resolver and breadcrumbs. B adds a large, well-tested URL DFA/canonicalization subsystem, but it is mostly isolated greenfield scaffolding under a vague commit with less demonstrated end-to-end impact than A’s cross-layer contract and UX changes.
