😊 Good news — Sentinel is safe to install

We get it: the internet is full of sketchy downloads, and we would never lump ourselves in with the crooks. So here's the honest scoop — Sentinel is brand-new, and our official code-signing certificate is still being issued. Until it's ready, Windows SmartScreen may flash an "unrecognized publisher" notice.

That's a reputation check, not a safety warning 👍 — it just means we're new, not that anything is wrong. The file you download is exactly what we published on this page, served straight from our own storage. 💙

To install: on Windows click More info → Run anyway; on macOS right-click → Open. That's it — you're good to go! Signed builds are coming soon, and these notices will disappear completely. 🎉
