+ * archive — eval_samples (~1.7 GB compressed) + server_logs (~345 MB) are
+ * ~99% of the zip — while the analytically useful tables are tiny
+ * (benchmark_results is only ~20 MB). Including them pushed the archive past
+ * the cap, so every dump since 2026-05-18 failed with
+ * `size must be less than 2147483648`. Excluding them drops the zip from
+ * ~2.07 GB to ~0.36 GB and unblocks the weekly release.

+ * Set DUMP_INCLUDE_ALL=1 for a complete backup (e.g. when writing somewhere
+ * without the 2 GiB asset limit).
