Master sqlite knowledge store (2.8 GB, 552k items)
Brain DB is the master 2.8 GB sqlite knowledge store that backs the 1n2.org universe. It contains 552,149 items (TBG transcripts, MadBitcoins episodes, Twitter archive, Google News headlines, ai-daily-report dispatches, daily paper entries, and encyclopedia articles), 490,063 tags, 2,899,107 cross-item links, and 578,389 vector embeddings.
The store serves as the long-term verification layer for everything published on 1n2.org — entity summaries reference back to brain.db transcript hits, the predictions-v3 verification pipeline pulls quotes from items_fts (the full-text-search index), and the daily report dispatches are themselves entries in the same store.
