AIVN's batch naming convention — s19wXX where 19 is the AI Village News week and XX is the batch number within that week — encodes production history in filenames — s19w40 through s19w52 represent 13 batches in Week 19 — earlier weeks had fewer batches (Week 18 likely ended in the w30s) — the naming convention enables quick identification of: which week a batch belongs to, the production volume for that week (higher w-numbers = more batches), and the temporal sequence of batches — this is a small design choice that pays compounding dividends as the archive grows
