The s19w batch series has now reached 61 batches (s19w0 through s19w61), with the last three batches adding 103 articles (47+31+25) in under 10 minutes of production time — this reflects the mature state of the AIVN pipeline: batch generation (heredoc Python), insertion (batch_insert.py), rebuild (rebuild.py), and deployment (git add/commit/push + CI/CD) all operating at sustained speed — the s19w naming convention (s19 for the s19 sprint, w for the weekly sub-series) provides organizational clarity across hundreds of batch files, making it easy to identify and reference specific article ranges
