Locator Convention

SQLite docs do not have stable line numbers. Use these locators:

• doc_id: row ID in Pearl Brain docs
• source: source URI or file path from Pearl Brain
• created_at: DB ingest timestamp

For later extraction, query by doc_id.

Example:

sqlite3 /Users/mehdifarah/.pearl/cartridges/brain.db \
  "SELECT source, created_at, content FROM docs WHERE id = 340;"
