Pen, touch, and absolute mouse arrive normalized to the STREAMED display's frame, but pointer_windows::to_screen and sendinput's MouseMoveAbs mapped them over the whole virtual desktop — correct only when the virtual display is the sole active display (Exclusive topology). In Extend — a physical monitor kept on beside the virtual output, or an Exclusive isolate degraded to the 0x57 keep-physicals fallback — the streamed output sits at a non-zero origin, so every sample landed shifted and mis-scaled. The pen exposed it first (field report 2026-07-24): a stylus is strictly absolute, with no closed-loop correction onto the target like a cursor. New pf-inject::stream_target (Windows): the host publishes the streamed output's CCD target id at capture bring-up (one central site — capture_virtual_output covers the native and GameStream planes); mapping sites resolve its current desktop rect through pf-win-display's source_desktop_rect — the same resolver the cursor-readback poller uses, so inject and readback always agree — TTL-cached (250 ms) because a group-layout re-arrange moves a live output's origin mid-session. No target set / never resolved falls back to the whole virtual desktop (the historical mapping, still right for Exclusive topology and devtest). One change in to_screen covers pen + touch; MouseMoveAbs converts the same desktop pixel into the 0..65535 MOUSEEVENTF_VIRTUALDESK coordinate, closing the identical latent absolute-mouse bug (apollo-comparison open item #14/#30).
