  "description": "Brazil's 2026 general election, tracked live. The bundle cross-references opinion polls formally registered with the Tribunal Superior Eleitoral against Polymarket's presidential odds and the press record, and publishes the resulting divergence series. It is the only live case in the AFOS collection: files are appended daily rather than frozen after a result. These machine-readable descriptors cover the stable tables only; the dated daily files under snapshots/, polls/ and news/ are append-only and are versioned by the commit history rather than by a descriptor that would go stale every day.",
