Trace Variants

8 alternate views of the UM forward pass. Each loads an SN model + raw data and computes traces client-side. See also the main Trace Viewer and the UM Viewer.

A. Error Anatomy

Classifies errors as sharp-wrong, missing-coverage, or unpredictable. Pie chart, histogram, scrollable error list with LPP breakdown.

B. Pass Comparison

Loads two SN models side by side, compares surprise per position. Difference heatmap and delta statistics.

C. Coverage Depth

LPP coverage heatmap — how many neurons fire per byte, when neurons are born, coverage gaps.

D. Neuron Lifecycle

Timeline of LPP entry creation and growth. Best with wm-blank.sn to watch online learning from scratch.

E. Sentence Algebra

Boolean sentence tree — the forward pass as ∨/∧ over support values. The UM's reasoning made visible.

F. Skyhook View

Context features (in_tag, word_len, xml_depth) computed from raw bytes, overlaid on model surprise. Top-down meets bottom-up.

G. Shift Chain Animation

6-phase animated circuit diagram of f. Comma/period keys step through phases. Watch the forward pass unfold.

H. Distribution View

Full 256-byte output distribution as a bar chart. Support values, entropy, s1−s2 gap, top-20 predictions.

These viewers evolved into the LATD Decomposition — the three-regime (L→A→T) interactive explainer with per-position traces, flow diagrams, and boolean sentences.
