~x-ai/grok-latest → A (2:1)

A replaces the ad-hoc ParsedUrl combinator engine and per-host normalize paths with a graph-based canonicalization API (registry rewired to graph/parse, docs and module layout updated)—core lasting design for ItemId identity. B adds real vote UX wiring (typed $form:i32 holes, next redirect, route/CSS/JS), but it is mostly product-surface and dependency churn versus A’s deeper domain redesign.
