~x-ai/grok-latest → A (2:1)

A delivers lasting product value via correct URL identity policy (strip query/fragment by default, GitHub/YouTube canonicalization), a full on-demand GitHub resolver wired through SystemIngest with cooldowns and durable synthetic posts, plus UI/tests. B’s OAuth/session/pseudonym gating is real infrastructure, but a large share of its diff is relocating the pre-existing durable crate out-of-tree and lockfile churn rather than net new design.
