+### PLT-009 - Split Apple Clipboard Helpers From Legacy Platform Adapter
+
+Status: Ready
+Score: +1 platform alignment and package parity
+Debt: `DEBT-0016`, `DEBT-0017`, `DEBT-0051`
+Scope: `src/platform_legacy/legacy_platform_services.cpp`,
+`src/platform_apple/apple_platform_services.*`
+
+Goal:
+
+Move Apple clipboard helper methods out of the catch-all legacy platform
+adapter into the Apple platform service boundary. Preserve clipboard behavior
+and keep non-Apple behavior unchanged.
+
+Done Checks:
+
+- `src/platform_legacy/legacy_platform_services.cpp` no longer owns the Apple
+  clipboard helper branch.
+- Apple clipboard get/set still dispatches through the Apple service path.
+- The debt log records the reduced Apple platform tail.
+
+Validation:
+
+```powershell
+ctest --preset desktop-fast --build-config Debug -R pp_platform_api_tests --output-on-failure
+cmake --build --preset windows-msvc-default --config Debug --target pp_platform_api_tests
+```
