These are the libraries we will build. 1. $viainti-devtools-core Universal #Dev Toolbar for #Nextjs A floating bar showing routes, global state, active queries, component render cost, feature flags, and simulated users — all via a simple <DevToolsProvider /> $SOL $PUMP #PumpBTC #PumpFunLaunch

2. react-contract-guardian Runtime FE/BE Contract Validator Hooks + components that validate $API responses (#REST/#GraphQL) using Zod, show errors in an overlay, and auto-generate a backend report.

3. next-env-switchboard Environment Switcher Inside the App #UI to toggle between local / staging / prod-mock with per-user persistence and environment badges. Safe-guards included.

4. react-permissions-lab Visual Roles & Permissions Playground Hooks + HOCs + a panel that lets developers preview the app as Admin, Manager, ReadOnly, etc., instantly.

5. dx-profiler-hooks Hook Performance Profiler Timeline visualizer showing how often custom hooks run, which dependencies triggered re-renders, and potential perf leaks.

6. next-latency-inspector SSR/ISR Latency Heatmap An overlay that colors each page section based on server-side render time, revalidate delays, and fetch latency.

7. react-testing-scenarios Visual Test Scenario Builder In dev-mode, lets you configure props, mocks, global state snapshots — then exports them to Jest/Playwright test files.

8. monorepo-status-dashboard Visual Dashboard for Turborepo/NX React component displaying package versioning, dependency graph, build failures, affected modules and PR diffs.

9. feature-flags-studio-react Feature Flag Simulation Studio Works with LaunchDarkly/Unleash/etc. Lets devs simulate user segments and instantly view UI differences.

10. design-tokens-auditor Real-Time Style Token Auditor Scans rendered UI, detects hardcoded colors/spacing and suggests reusable tokens. Exports to tokens.json automatically.
