- Fix grammar state machine in EXICodecExact.cs to match C implementation - State 281 now uses 2-bit choice (not 1-bit) as per ISO spec - EVTargetVoltage now correctly decoded: Unit=4, Value=460/460 - RemainingTimeToBulkSoC now correctly decoded: Multiplier=0, Unit=2 - test4.exi and test5.exi produce identical XML output to VC++ version - Complete C# program with identical command-line interface - XML namespaces and structure 100% match C reference - Core V2G data perfect: EVRESSSOC=100, SessionID, all fields 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
