entviz v3 gallery

Real-world inputs rendered with the current v3 implementation (/home/daniel/code/v3 at the tip of branch v3). The yellow-tinted cards are avalanche pairs — two inputs differing by a single hex digit (or one bit). Compare them to see the fingerprint-driven channels diverge while the text channel stays nearly identical.

What to look for: the cubist (C1–C3) and polygon (P1–P3) shape sets on the edges, with empty slots (C4/P4) appearing as ~1-in-4 gaps; the fourth-power-skewed color bar on the left where a dominant color visibly claims most of the height; the shape count summary below the grid in X## digit format (slot 4 omitted as derivable); the ellipse overlay on inputs ≥ 256 bits, anchored at an interior grid corner, axes drawn from [cell_h, d_far − cell_w], rotation 0–180°, fixed 20% opacity, clipped to the grid rect. Hex-typed inputs render their 6-char cell tokens at 75% of the reference font size so they fit the nucleus.

Small inputs (under 256 bits) — no ellipse overlay

Inputs below the 256-bit threshold skip the ellipse per spec; the grid is too small (fewer than 6 interior corners) for the curve to land meaningfully. The UUID and random-128 pairs are the headline avalanche tests: identical-looking text, completely different shapes and colors.

Larger inputs (≥ 256 bits) — overlay drawn

At 256+ bits the grid is big enough (≥ 3×4 / 4×3) for the ellipse overlay to contribute a gestalt silhouette. The two large-hex cards at the bottom right are an avalanche pair on 544-bit input — they share the first 512 bits and differ only in the final byte; the text channel truncates to head + blank + tail, but the fingerprint sees the full input so the channels diverge.
