Current — September 2026

Data fidelity audit and remediation

  • LoraDeltaViz — weight delta is now the real sampled mean-absolute- difference from the quant-diff path. Previously computed from a hash of the tensor name.
  • ResidualContributions — now measures real PCA-space residual deltas per layer. Previously used Math.random() magnitudes.
  • ActivationPatchCompare — wired to real logit-lens trajectory. Previously added (Math.random() - 0.5) * shift to produce “patched” output.
  • NumberProvenance — hardcoded 0.42 / 0.87 values removed. Panel now states that real values require GET /debug/tensor.
  • Added frontend/scripts/verify-data.sh wired into npm run buildto prevent regressions.

Walkthrough chapter differentiation

  • Each of the 7 chapters now has a distinct chapter-specific 3D visual.
  • Tokenization chapter: real vocabulary ID chips per token.
  • Self-Attention chapter: live attention heatmap with head selector.
  • Softmax & Output chapter: top-k probability bar chart from real logit lens, prediction game.

Modals redesign

  • HuggingFace Model Explorer modal — monochrome redesign, verified model data.
  • Plugin Manager modal — functional plugin list with toggle controls.
  • Settings modal — aligned to app design system.

Documentation system

  • New /docs route with full product documentation.
  • 27 pages across 5 sections: Getting Started, Core Concepts, Using TokenPrint, API Reference, Reference.
  • Persistent left sidebar navigation, right-side section anchors, prev/next navigation.
  • All content verified against real model data.
