Addressed Issues:

Implements the static frontend according to docs/FRONTEND_CONTRIBUTOR_BRIEF.md.


Overview & Key Features

Visitors need to distinguish model provenance, scoped replay reports, and model availability. This PR introduces an isolated, static React/TypeScript/Vite frontend with an enhanced modern design system, interactive 3D elements, and strict adherence to project goals:

  • Enhanced Design System & Dynamic Aesthetics:
    • Interactive 3D Globe: Built with cobe and WebGL in the shared footer on every view.
    • Container Scroll Animation: Powered by Framer Motion on the Evidence Explorer view, providing smooth scroll-driven perspective tilt.
    • Scroll-Drawn Edge Lines: SVG organic curves hugging the screen edges that draw dynamically as you scroll.
    • Modern Editorial Typography: Bricolage Grotesque display headings, Instrument Sans body, and JetBrains/IBM Plex monospace code labels on glassmorphic card surfaces with a curated organic palette (#5e6c5b, #f4efe6, #fefcf6, #d6e0e2, #686867, #162a2c).
    • Viewport Scroll Reveals: Content blocks smoothly fade and elevate into position as they enter the viewport.
  • 6 Responsive Views:
    1. Overview / Mission Control: Purpose statement, 7-stage verifiable pipeline timeline, release availability disclosure, and check summary.
    2. Evidence Explorer: Container scroll perspective cards, multi-facet filtering (Phase, Scope, Kind, Result) with static-safe URL hash state persistence.
    3. Evidence Detail: Full SHA-256 digest copying with Clipboard API feedback, parent/child lineage graph, and preserved historical/superseded reports.
    4. Model Releases: Base (1.1B) and Conversational model cards. Gated as "Not released yet" with disabled download actions until immutable releases and manifests exist.
    5. Verification Guide: Distinct documentation for all 5 verification profiles (Artifact Identity, Data Reconstruction, Sampled Replay, Full E2E Replay, Inference Reproduction) with resource/hardware estimates and tested syntax placeholders.
    6. Inference Preview (Sandbox): Cleanly isolated development mock adapter with clear "Example UI response — not generated by a released model" banner.
  • Strict Claim & Status Semantics:
    • Standardized verification results (PASS, FAIL, NOT_RUN, UNAVAILABLE, UNSUPPORTED) are strictly separated from workflow progress and loading states.
    • Transparent attribution separating Publisher Report, Project-Operated Replay, Consumer Recomputation, and Independent Third-Party.
    • Runtime Zod schemas reject empty, malformed, or missing metadata; empty checks never render a false overall pass.
  • Isolated & Safe:
    • Confined 100% within frontend/ — zero modifications to Python training pipelines, core verifiers, signing keys, or project operational state.
    • Production builds tree-shake and strip all mock inference code (verified via scripts/check-production.mjs).

📝 Walkthrough

Walkthrough

The PR adds a React and TypeScript frontend that loads validated snapshot data and presents evidence, release, and verification views. It also adds a development-only mock inference interface, responsive visual components, and frontend build, delivery, and test support.

Changes

Frontend application

Layer / File(s) Summary
Build, static delivery, and project setup
frontend/package.json, frontend/*config*, frontend/index.html, frontend/src/main.tsx, frontend/scripts/*, frontend/.env.example, frontend/.gitignore, frontend/README.md, frontend/CHECKLIST.md, frontend/PR_HANDOFF.md, frontend/VALIDATION_REPORT.md, frontend/licenses/*
Adds package scripts and configuration for the React frontend, static serving, production checks, and tests. Documentation describes setup, validation, integration boundaries, and remaining maintainer inputs.
Snapshot contract and loading
frontend/src/data/*, frontend/public/data/snapshot.json, frontend/tests/contracts.test.ts, frontend/tests/browser/frontend.spec.ts
Defines strict snapshot schemas, URL and response-size checks, loading and stale-data handling, and development scenarios. Adds a synthetic fixture and tests for validation and loading outcomes.
Routes and snapshot views
frontend/src/App.tsx, frontend/src/router.ts, frontend/src/pages.tsx, frontend/src/components.tsx, frontend/tests/pages.test.tsx, frontend/tests/browser/frontend.spec.ts
Adds routed overview, evidence, release, and verification pages. The views display supplied records and missing-reference states, preserve evidence filters in the URL, and restrict fixture downloads.
Development mock inference
frontend/src/inference/*, frontend/tests/inference.test.ts, frontend/tests/browser/frontend.spec.ts
Adds an inference adapter contract, response checks, scripted mock scenarios, and a development interface with cancellation and conversation history. The inference route remains unavailable outside the development interface.
Responsive shell and visual components
frontend/src/chrome.tsx, frontend/src/styles.css, frontend/src/components/ui/*, frontend/tests/browser/frontend.spec.ts
Adds responsive navigation and layout, reduced-motion handling, scroll effects, a globe, and pointer-responsive glow cards. Browser tests cover responsive layouts, keyboard navigation, and reduced-motion behavior.

Merge Risk: 🟡 Moderate · up to c20b1

Align the browser-test setup with its installation instructions before merging. Also correct release-parent validation and snapshot path confinement; the remaining visual defects are localized.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c20b1

The interface can select data outside its intended deployment directory under some configuration settings. Requests omit credentials, and the development preview does not execute a production model, limiting impact. Actual deployment settings remain unverified.

Retained concerns

  • Low · security · observed: The newly introduced snapshot boundary compares raw pathname prefixes rather than directory segments. With a base such as /project, a configured target such as /project-private/data.json can pass despite being outside the intended directory. Exposure depends on deployment configuration; the inspected caller does not expose the snapshot path as visitor input.
Security review details

Security Blast Radius

  • inferred — The demonstrated confinement weakness affects the configured display-data selection of a frontend deployment. Exercising the sibling-path case requires suitable base and snapshot-path configuration; direct control by an anonymous visitor, credentialed access, tenant escalation, or server-side filesystem exposure is not established.

Security Findings and Attack Paths

  • observed — The retained finding concerns a newly introduced directory-containment control: a slashless base allows a same-origin sibling pathname sharing its prefix to pass. Existing tests cover parent traversal and another origin, but not this sibling-prefix case. Deployment values determine practical exposure.

Trust Boundaries and Controls

  • observed — Initial snapshot URLs must use HTTP(S) and match the page origin. Credentials are omitted, response size and data shape are bounded, and configured mode is enforced before display. External links separately require credential-free HTTPS URLs and use opener isolation. These controls do not authenticate snapshot authorship.

Resilience and Maintainability Implications

  • observed — Development inference assigns each request a controller identity, aborts predecessors, and rejects stale completion updates. Clear, mode change, and unmount perform cleanup; empty output does not enter conversation history. Release identity, decoding settings, input limits, response identity, and mock-mode parity are checked before committing output.

Hardening Proposals

  • proposed — Normalize the deployment base to an explicit directory boundary and enforce segment-aware containment. Exercise slashless bases and sibling-prefix paths alongside the existing traversal and cross-origin cases.

Review comments at @frontend/playwright.config.ts:
- Line 5: Update the browser options in the Playwright config to use the
Chromium browser installed by the documented setup; remove the branded Chrome
channel selection so npm run test:browser works on a clean machine.

Review comments at @frontend/src/components/ui/globe.tsx:
- Around line 65-73: Update the state read by onRender so the callback retained
by createGlobe reads current rotation, drag offset, and width values instead of
captured values; store phi, r, and width in refs and update their current values
in the existing interaction and sizing paths.

Review comments at @frontend/src/data/contracts.ts:
- Around line 44-45: Update the snapshot validation around the available-chat
parent check to require parentReleaseId to match the id of the snapshot’s base
release, not merely be present. Keep unresolved checkIds allowed so the frontend
can render them as missing check references.

Review comments at @frontend/src/data/load.ts:
- Line 9: Normalize the base path to end with a slash when constructing root in
the snapshot-loading confinement check, so a base such as /project cannot match
sibling paths like /project-private. Keep the existing origin, pathname, and
protocol checks unchanged.

Review comments at @frontend/src/styles.css:
- Line 156: Define the missing --mono and --sans custom properties in the :root
rule so the footer font declarations using var(--mono) and var(--sans) remain
valid; leave the existing footer declarations unchanged.
