All units share one link namespace (per-unit isolation is PLAN-C C3.2, deferred), so a symbol defined by two units previously died inside the JIT dylib link or the AOT link with raw linker spew. The clang shim gains sx_clang_object_exported_symbols (llvm::object scan: defined + global, format-specific excluded) and compileCToObjects cross-checks every unit object — collisions name both source files. Scan failures are non-fatal; the linker remains the backstop. Covers JIT and native AOT; the emcc path still relies on wasm-ld's own error.
