Mercury-Viewer (10.5281/zenodo.20313150) established a design pattern for transformer interpretability tooling: a single self-contained HTML file, no install, no server, no API key, that opens in any browser and renders the inside of a transformer language model as an interactive 3D point cloud.
This artifact paper releases three follow-on tools applying the same pattern to three different questions:
- overlap.html — cylindrical 3D point cloud of the 49-coordinate cross-model overlap and the 11-coordinate triple-confirmed subset from the cross-model dimensional preservation analysis (Mercury Paper A).
- frankenstein-v1.html — three side-by-side cones showing qwen2.5-7B-Instruct, the SLERP merge, and qwen2.5-Coder-7B-Instruct, with 11 rose-gold lines marking protected anchors and the merge cone colored by SLERP t value.
- frankenstein-arena.html — frozen snapshot of one inference pass rendered as cargo orbs traveling on cables between functional rooms (universal core, language detector, physics reasoning, etc.).
All three artifacts: single HTML file, no build step, no API key, no GPU dependency, every visible artifact hoverable, every numeric claim tied to an integer coordinate. Live at charenix.com/neuron-mercury/.
Limitation: no user study run. Pedagogical claims are informal.
