+/// The last entry is `tauri-plugin-updater`'s own non-success log line
+/// (`updater.rs`: `log::error!("update endpoint did not respond with a
+/// successful status code")`). The plugin emits it on *any* non-2xx
+/// response and **discards the status code**, so the Sentry event carries
+/// no `domain`/`status` tag and no actionable detail — it can only be
+/// matched by this message string. It is distinctive to the updater
+/// (literally names "update endpoint"), so matching it domain-agnostically
+/// is safe. A genuinely-broken update manifest still surfaces with full
+/// structured context (status + url) through the core's `domain=update`
+/// `check_releases` path, which keeps non-transient statuses visible — see
+/// `UPDATER_TRANSIENT_HTTP_STATUSES` (404 deliberately omitted there).
+/// Drops TAURI-RUST-CD (~151 events / 9 days, Windows background checks).
