Replace the EXTRA_TICKET_NUMBER ticket sentinel with a dedicated ExtraBatchDraw table keyed by (batch_id, round_id), plus a Batch.extra_draws relationship. Extra batches are audited to meet state requirements but don't count toward risk measurement, so modeling them separately from SampledBatchDraw keeps them out of risk queries by default rather than relying on a magic ticket number.

…rement Compute extra batches once per round across all jurisdictions, decoupled from individual contests, and persist them as ExtraBatchDraw rows alongside the RLA sample. Extra batches are audited but must not count toward the risk calculation. Because they're no longer SampledBatchDraw rows, the risk and result reads (count_audited_votes, sampled_batch_results, round reports) only look at SampledBatchDraw and therefore exclude them; they are pulled in only where non-RLA batches are explicitly requested. Update combined-batch representative selection and the round-completion check to use ExtraBatchDraw. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Include extra batches alongside RLA sampled batches in the jurisdiction batch list, retrieval list, progress counts, cross-round dedup, and the finalization guard, so they're pulled, audited, and required to have results like any sampled batch. Also surface discrepancies found in extra batches in the discrepancy report. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
