Fixed in 9af38d2. net::ERR_INTERNET_DISCONNECTED is a benign offline/transient-network condition during the update check (auto-update just can't reach the server). New isTransientNetworkError() routes these (and other net::ERR_* / Node socket errnos) to a benign not-available state — exactly like the missing-config case (#14) — so they no longer report to Sentry; genuine errors (e.g. sha512 mismatch) still report. Verified by unit tests + the full coverage gate. Ships in the next release (v1.15.13).
