about

nx_par_pull.nx -- PARALLEL concurrent download (the max-speed S-class gap): fork one worker per file, each running the resumable streaming pull over its OWN TLS-1.3 connection, all downloading AT ONCE. Staged to fast local disk (/tmp = ext4, not the 9p NAS mount that bottlenecks + crashes WSL) -> both faster AND stable; a caller then does one big sequential copy to the NAS. Reuses nx_https_get_stream + nx_https_fetch_follow's plumbing (same as the sequential nx_apertus_shards_pull; the pull loop is duplicated here as the parallel driver's worker body). Demonstrated live pulling several real Apertus files concurrently. license_tier: ORIGINAL expect_exit: 0
