XMP flattening, sparse-focus EXIF decode (plus the maker-note and TIFF value
budgets), lossy-DNG chunk staging, panorama stitch frames, the reference ONNX
executor's tensors and the denoise product reader all now reject or cap what a
malformed file can make them allocate: each result is checked before the
memory behind it is reserved, every regression carrying a test that fails
without its bound.
