AI-powered related signals

AI-related-signals augments the editor-curated cross-module graph with machine-suggested links. Today every relatedXxxId is hand-set; the AI layer would suggest "this article should probably also mention these 3 founders" or "this event might be relevant to these 5 startups" — humans approve or dismiss, the suggestion never auto-commits.

Signal sources

• Co-occurrence in bodyHtml: if two founder names appear in the same article, those founders should likely cross-reference each other on their profiles. Suggest, don’t auto-link.
• Embedding similarity: vector representation of an editorial article finds the 5 closest events / opportunities / files in embedding space. Editor reviews and accepts the best.
• Temporal proximity: events happening within 30 days of an article’s publishedAt are surfaced as candidates for relatedEventIds.
• Citation graph: founders + startups mentioned across multiple coverage articles become candidates for each other’s cross-references.
