 **Hard-won CI rules:**
 - `includeUpdaterJson: true` must be set in tauri-action — without it `latest.json` is never uploaded and the auto-updater silently does nothing
+- `bundle.createUpdaterArtifacts: true` must be set in `tauri.conf.json` — without it `.sig` files are never generated even if the signing key is set (Tauri 2 requirement)
 - Valid `bundle.targets`: `"deb"`, `"rpm"`, `"nsis"`, `"msi"`, `"dmg"` — do NOT add `"updater"` (that's a plugin, not a bundle format)
 - macOS runner is `macos-latest` (ARM only) — `macos-12`/`macos-13` are gone
