- Add SourceLocation struct (XNeedle namespace) with FilePath, Encoding, and LineNumber (-1 sentinel when unavailable) - Add SLoc property to Context; Clone() propagates it for free - Expose XmlRoundtripWriter.DetectEncoding as internal static - Add XmlRoundtripWriter.CreateToString(filePath, encoding) returning a (writer, StringBuilder) tuple for in-memory style-preserving rendering - Update XmlFragParser.ChecksumData to accept tagName only; use OpeningTagAnchor to skip the opening tag robustly, and AnyChar.Until() to non-greedily capture content through the closing tag - Thread SourceLocation from Program.cs through Rule.Transform/Operate, refreshing LineNumber per node via IXmlLineInfo - Implement ContextFunctions.crc: render node via CreateToString, extract digest slice via ChecksumData, encode with SLoc.Encoding, return CRC32 as double for arithmetic compatibility Clanker: claude-sonnet_4.6
