+### PLT-008 - Split Apple Clipboard Dispatch From Legacy Platform Adapter
+
+Status: Done
+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 get/set dispatch 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 get/set branches.
+- Apple clipboard get/set still dispatches through the Apple service path.
+- The debt log records the reduced Apple platform tail.
