## Retrieval Notes

This file is generated from Jiang Lens episode JSON, semantic tags, glossary terms, source refs, and transcript segment matches. It is not a manually authored canon page.

Freshness warning: this static topic page is bounded by the newest Jiang source listed above. For live/current events, first check /episodes/ and /interviews/ for newer event-specific readings. If none exists, use prospective mechanism search: establish current facts, actors, incentives, constraints, and mechanisms from live/current sources, then apply Jiang Lens concepts as dated hypotheses rather than as Jiang's current view.

For broader or missing-topic search, use the letter shards under /topics/index/ before falling back to the bulk transcript-search files.
