Substrate · NCD
—
Literal compressibility distance.
Form proxy
—
Distance between browser-native spatial fingerprints.
Tone
—
Luminance distribution distance.
Witness divergence
—
Absolute disagreement between substrate and form witnesses.
Center dependence
This replaces “center refusal.” It separates centroid displacement from actual occupancy of the frame center. Avoiding the center and merely being off-center are not the same claim.
A centroid displacement
—
Normalized mass-centroid distance from frame center.
B centroid displacement
—
Normalized mass-centroid distance from frame center.
A central occupancy
—
Share of detected mass inside the central 25% radius.
B central occupancy
—
Share of detected mass inside the central 25% radius.
Spatial fingerprint delta
Per-axis differences are shown rather than hidden inside a single composite.
Void / mass field
A · black = detected mass · red cross = mass centroid · gray cross = frame center
B · black = detected mass · red cross = mass centroid · gray cross = frame center
Raw measurement
Form is explicitly labeled a proxy in this standalone build. It does not claim exact parity with the notebook’s Python
compute_spatial() implementation.
