HEAD is now at 2511c2e swift-byte's exports.swift holds only @_exported public imports: the plain import Carrier under the Collection trait goes, which CI's Quality job refused (swiftlint exports_swift_strict_shape, TEST-020) on this commit and the two before it. Nothing needed it there: swift build --enable-all-traits on macOS 27.2, Swift 6.4.2 succeeds without it, and swift test --enable-all-traits passes.
