+- **Repo Update** (2025-09-29 – jarroddavis68)
+  - Switched from kyx0r single-file TCC to official TinyCC repository for better runtime support
+  - Fixed critical workflow state bug preventing multiple CompileString/AddFile calls in sequence
+  - AddFile and CompileString now correctly allow multiple calls in wsConfigured or wsCompiled states
+  - This fix enables proper multi-file compilation workflow (e.g., compile to .o, then link with main)
+  - Official TCC provides proper libtcc1.a runtime library and startup code for EXE generation
+  - Added comprehensive documentation distinguishing Reset() vs Clear() methods
+  - Reset() now documented to preserve callbacks while Clear() removes all configuration
+  - Improved XML documentation for both methods with clear examples of use cases
