A telemetry batch containing two rows with the same RowKey made Azure Table Storage reject the entire entity-group-transaction with HTTP 400 / InvalidDuplicateRow, surfacing as HTTP 500 on POST IngestTelemetry. Observed as a 23-minute spike (36x 500) from a single session replaying an overlapping SessionSignalOrdinal; self-resolved when the agent stopped retrying. The three V2 ingest write paths (Signals, DecisionTransitions, Index) built the transaction without deduping duplicate RowKeys and had no fallback (unlike the Events path). Add a shared TableBatchDedup.ByRowKey helper that collapses duplicate (PartitionKey, RowKey) entities last-write-wins (idempotent UpsertReplace) and logs a WARN with the dropped count, so bad agents become visible in logs instead of failing the batch. SubmitTransaction stays fail-loud for any other batch error. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
