about
nx_apertus_shards_pull.nx -- S-CLASS resumable, self-healing shard pull (operator: max speed / resume / error
handling). Streams each shard to the NAS via nx_https_get_stream (one TLS conn, no buffering), and:
RESUME -- before each attempt, lseek the .part to its current size and request "Range: bytes=<size>-" so a
broken/killed download CONTINUES from where it stopped (never re-fetches the bytes already on disk).
RETRY -- wraps each shard in an attempt loop: on any error (NAS write fail, read timeout, connection drop) it
reconnects and resumes; progress resets the try counter (self-healing), only true stalls exhaust it.
SAFE -- if a server ignores Range and returns a full 200, get_stream returns -9 and we truncate + restart
(never append a full body onto a partial). Final integrity is still checked by nx_apertus_shard_verify.
Reuses nx_https_fetch_follow's plumbing (ff_path/ff_resolve_location/url_connect/session_run). license_tier: ORIGINAL
