 - nextTask: `NONE`

 The completion overlay graduates only two exact operator IDs whose color/weight protocol behavior was verified in deterministic Chromium/WASM Main receipts. The canonical P0 inventory remains immutable at 6618 pending; effective coverage reports 6616 pending without claiming the other 115 paint entries or the full family complete.
+- authorized continuation: `WBV2-P17-000`
+
+Object Operations may continue under a new root without changing the P16 paint overlay.
