+**Job Failure Summary**
+
+See failing job: https://github.com/GordonSmith/component-model-cpp/actions/runs/18194501364/job/51797087211 (ref: 72f9cdab020b5835cba3df2bcd2fcfc1cc3cac79)
+
+#### 1. WASI SDK/Clang Dynamic Library Not Found
+```
+dyld: Library not loaded: @rpath/libclang-cpp.dylib
+Referenced from: .../build/vcpkg_installed/arm64-osx/wasi-sdk/bin/clang-19
+Reason: tried: .../lib/libclang-cpp.dylib (no such file)
+```
+- Solution: Ensure libclang-cpp.dylib is present in wasi-sdk/lib/. Reinstall WASI SDK or set DYLD_LIBRARY_PATH appropriately.
+
+#### 2. No Matching Constructor for cmcpp::InstanceContext
+```
+error: no matching constructor for initialization of 'cmcpp::InstanceContext'
+candidate constructor ... not viable: requires 1 argument, but 3 were provided
+```
+- Solution: Add a constructor to InstanceContext matching the arguments provided, or fix instantiation to use correct arguments.
+
+#### 3. Constexpr Initialization Errors in traits.hpp
+```
+constexpr variable 'flat_types' must be initialized by a constant expression
+static constexpr std::array<WasmValType, flat_types_len> flat_types = []() constexpr { ... }
+```
+- Solution: Refactor initialization so all expressions are compatible with C++17/20 constexpr rules. Avoid lambdas in constexpr context.
+
+#### 4. Template Deduction Failure for flatten
+```
+no matching function for call to 'flatten'
+candidate template ignored: failed template argument deduction
+```
+- Solution: Explicitly specify template arguments, and ensure calls match the function signature in func.hpp.
