HEAD is now at cab8319 Domain's IDNA conversions catch IDNA.Error by type and say why with its description, instead of catching any Error and interpolating it, which Embedded Swift cannot specialize: swift-html's Embedded build stopped at Domain+IDNA.swift 11 and 22. The validation of the converted name now runs outside that catch, so a name that converts but is not a valid domain throws its own Domain.Error instead of being wrapped as an IDNA failure. swift test on macOS 27.2, Swift 6.4.2: 48 of 49 and 3 of 3 pass; the one failure is the existing swift-standards/swift-domain-standard#11.
