## 📋 Known Considerations
### Legacy Warnings
**Status:** Expected and acceptable
The following legacy warnings exist in the codebase and were **not introduced** by this work:
- CS1998 warnings in test mock files
- These existed before Phases A-C
- No new warnings were added
- Safe to proceed
### NT8 Strategy Compilation
**Important:** The strategy .cs files:
- Are **not compiled** into NT8.Adapters.dll
- Are deployed as **source files** to NT8
- Must be compiled **by NinjaTrader 8**
- This is by design (required for NT8 integration)
### First-Time NT8 Compilation
**Potential Issues:**
- Missing NT8 DLL references (should auto-resolve)
- Strategy namespace conflicts (none expected)
- C# version mismatch (validated as C# 5.0 compatible)
**If Issues Occur:**
1. Check NT8 version (8.0.20.1+)
2. Verify .NET Framework 4.8 installed
3. Review NinjaScript Editor error messages
4. Consult TROUBLESHOOTING.md in deployment guide
