v0.342.0 (unreleased): the upload and CPU watch — an app that sends or burns far more than its own numbers explain is one operator-only alarm; the line learnt from the off-site push; qBittorrent's default upload limit (never over the household's)

internal/upwatch: exact per-container counters from the Docker Engine API, per-app judging (upload >= max(5 Mbit/s,
25% of the line) for 15 min; CPU >= max(150%, 50% x cores) for 30 min), explainers qBittorrent / Transmission / Plex,
app_unexplained_upload / app_unexplained_cpu + _cleared (hub 0.169.0). The off-site push is sampled once a second
for the line (a lower bound). qBittorrent limit = 50% of the line, the household's limit always wins. 20 red-proofs.
Spike + design: felhom.eu audits/SPIKE-upload-watch-2026-10-23.md, architecture/08 section 9. Not released.
