    "Node execution of shipped WASM; no browser UI, GPU, physical-device or native-app acceptance.",
    "Every archive header scanned, representative objects selected per series; not every object decoded.",
    "Exact local input archive hashes recorded; original upstream revisions unknown.",
    "Independent pixel comparison covers only the first frame of selected monochrome objects.",
    "First/middle/last rendered frames checked for size and opacity; no independent rendered-pixel comparison.",
    "Raw source matrix comparison does not validate Siemens mosaic unpacking, MPR or measurement tools.",
    "Enhanced functional-group objects are explicitly unsupported; matching rejection behavior does not mean successful decoding.",
    "Nonempty decoded images and numeric geometry checks do not establish clinical validation."
