# ATTEMPT 1 (16:13–16:27 CEST) — stopped by CC. Radarr approved and grabbed (qBittorrent drive-b took it: category
# movies-drive-b, save path media_b/.../torrents/movies, incomplete path media_b/.../torrents/.temp — read from
# qBittorrent's own torrents/info). The download stalled at 6.09 % (32 MiB): 0 peers, and archive.org's web seed
# answered "500 Internal Server Error" (qBittorrent log, URL https://dn721601.ca.archive.org/); stop/start did not
# revive it. A plain curl range request to the same file from the same container answered 206 at the same time.
# So the source, not the chain, stalled. The run was stopped and retried (below).

# NOTE on attempt 2: qBittorrent reached 99.994 % at ~16:41 (7.7 MB/s from archive.org's web seed) and then stalled on
# the LAST piece (the film's tail + archive.org's three side files: __ia_thumb.jpg, _meta.sqlite, _meta.xml). Its log
# shows "Received error message from URL seed ... dn721505.ca.archive.org ... 500 Internal Server Error"; 8 stop/start
# retries over 6 min did not help, while curl range requests for the same three files from DooPlex answered 206. To
# finish, CC added the SAME public-domain torrent to Transmission (download dir media_b/.../transmission/s2-helper) and
# gave qBittorrent Transmission's container address as a peer (POST /api/v2/torrents/addPeers 172.18.0.9:51413) at
# 17:03; qBittorrent completed within 40 s and Radarr imported. The chain itself (grab by client, category save path,
# move from .temp, hardlink import) is unaffected; the source's web seed was the fault.
