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).

// Hash display helpers — see docs/style-guide.md §4.4.
|
|
//
|
|
// Atomic identifiers (SHA-256, IPFS CIDs, signatures, JWTs, UUIDs…) must
|
|
// never wrap mid-token. Visual diff degrades to a character-by-character
|
|
// scan when two hashes wrap at different columns. These helpers render
|
|
// hashes in the two non-truncated styles defined by the guide:
|
|
//
|
|
// chunkHex(h) → Mode B: "38f82216 97ee54dd …" — fixed 8x8 groups,
|
|
// wraps only at chunk boundaries. Use in .root-hash-block.
|
|
//
|
|
// shortHex(h) → Mode C: "38f82216…b1042270" — first 8 + last 8 hex.
|
|
// Always pair with title= and a click-to-copy affordance.
|
|
//
|
|
// Mode A (inline one-line scroll) needs no helper — just render the hash
|
|
// verbatim inside a `white-space: pre; overflow-x: auto` container.
