Call for Contribution: Modern Web UI & Interactive Timeline for Offline Receipts & Undo History

[mahirhir]

Background

Tracefold's verification engine (\gx receipt verify, \gx tile) runs offline via CLI, and emits DSSE-attested JSON receipts and append-only tile logs. Currently, web-based receipt viewing and timeline exploration relies on minimal plain HTML/SVG templates.

What is needed

We want a clean, high-density Web UI / dashboard (React, Svelte, or vanilla web components) that can:

1. Offline Receipt Inspector: Drop a .dsse\ receipt file into the browser, verify Ed25519 signatures and Cedar policy statements client-side (via WASM), and display the audit tree.
2. Interactive Undo Timeline: Scrub through turn boundaries and view pre-commit reverse diffs with syntax highlighting.
3. Merkle Tile Explorer: Visual tree showing inclusion proofs and checkpoint consistency without external network calls.

Scope & Tech Stack

• Frontend: Open to proposals (Svelte / React / Solid / pure HTML+Tailwind). Zero mandatory cloud backend — must work fully offline (PWA or single-file HTML/WASM bundle).
• Design language: High visual density, dark mode by default, fast keyboard navigation.
