   Anthropic moved newer Claude models to dateless model IDs (still pinned)

   Anthropic stopped issuing dated snapshot IDs for newer models (the 4.6 generation onward) in favor of dateless IDs. Per Anthropic's model docs these dateless IDs are still pinned snapshots, not floating pointers - so version pinning is intact.
