about

nx_dlperf_research_fetch.nx -- SOVEREIGN researcher for S-CLASS download PERFORMANCE + RELIABILITY (operator: "maximum speed, resume capabilities, error handling"): the aria2/axel/wget/curl bar for high-throughput, resumable, fault-tolerant transfers. Banks each source to knowledge/fetched/dlperf_*.raw so nx_dlperf_census can grade our streaming pull against a real corpus (>=2-source no-hearsay). Same proven pattern as the mirror researcher: own TLS-1.3 + Mozilla CA, idempotent have-skip. Axes: A parallel/segmented, B resume(HTTP range), C retry/backoff/fault-tolerance, D throughput/TCP, E integrity, F connection reuse. expect_exit:0 license_tier: ORIGINAL
