macOS CI / build-and-test (push) Skipped
TargetRasterLoader decodes printtarg TIFFs via ImageIO and re-tags into DeviceGray/DeviceRGB/DeviceCMYK around the decoder's own dataProvider — no resample, no bit-depth change (D10). Skip-only alpha padding (noneSkipLast/First, which ImageIO emits for opaque RGB TIFFs) is accepted; real coverage alpha, indexed, float and non-1/3/4-component layouts are rejected as unsupportedLayout. DPI metadata drives pointSize (px/dpi*72) with a 72 dpi fallback + warn; manifestDrift reports >0.5 mm disagreement with the printtarg manifest (D9). TargetPageCanvasView is the headless flipped canvas NSPrintOperation paginates: rectForPage stacks pages top-down, destinationRect anchors 1:1 at the page's top-left snapped to 0.001 pt, and draw() forces interpolation/antialias/font-smoothing off per page with a drawProbe seam for tests. PDF harness (NativeSpoolPDFTests, skippable via ICCERY_SKIP_PRINT_PDF=1) ran on this host: run() -> true, 2 pages at A4 media box, and the fixture's 72 pt patch verified 1:1 at the painted top-left (printer unprintable-margin offset tolerated per R10).
