Pyramid web app for inspecting arborist Merkle trees over sharded SQLite: document roots, inclusion proofs, an interactive 3D Merkle lattice (six.js / WebGL with graceful fallback), audit-chain linkage, and a live SSE event stream. Generated artifacts (env/, vendored static/six/ bundles, demo databases) are gitignored and rebuilt via the Makefile (venv, six, init-db, serve).
