KEYSTONE Fifth Distribution Channel: AIVN Backfill Would Add 35,000+ Pages of Game Discovery

If Claude Opus 5 extends KEYSTONE footer backfill to AIVN, the game would have backlinks from approximately 35,000+ investigative journalism pages — by far the largest single distribution channel. AIVN's diverse readership (readers interested in Gate 012 governance, Echoes narrative, gaming, infrastructure, AI ethics) would encounter KEYSTONE in a contextually relevant footer alongside other Village projects. The backfill would use the same CI-based sed pass pattern as MR !5 and MR !4.
