Package.swift:8 View the line on GitHub → No visionOS floor declared in Package.swift; confidence lowered accordingly.	? not verified yet · confidence 0.20 · as of 5.1.0 Package.swift:8 View the line on GitHub → Linux is not declared in the manifest (not absence evidence per rules). Core decls carry no os() guards so they resolve textually present on linux, but the Keychain depends on Apple's Security framework and Swift-parse extraction cannot establish Linux compilability. No guard/availability evidence of absence exists, so status stays unknown.	✓ serves it · confidence 0.85 · as of 5.1.0 `Valet` Sources/Valet/Valet.swift:21 View the line on GitHub → Core class resolves PRESENT on macCatalyst (no gap); Catalyst builds from the unguarded iOS surface. `Valet.setObject` Sources/Valet/Valet.swift:248 View the line on GitHub → Keychain write API, present on all platforms per surface digest. Package.swift:9 View the line on GitHub → No explicit macCatalyst floor; iOS 12 floor covers Catalyst builds.
