For each official release, verify:

| Check        | What to confirm                                         |
| ------------ | ------------------------------------------------------- |
| Signature    | Developer ID Application signature on the app / DMG     |
| Notarization | Stapled ticket; Gatekeeper accepts on a clean Mac       |
| Checksum     | SHA-256 matches the published checksums / manifest      |
| Provenance   | GitHub attestations bind the artifact to the source SHA |
| SBOM         | Published SBOM matches the release set                  |
| Updater      | Website latest version equals updater metadata version  |
