Phase 3 Plan 01: JS Toolchain Setup Summary

One-liner: esbuild + TypeScript + Vitest pipeline for d3 heatmap development with jsdom test environment.

What Was Done

1. package.json -- Created with build/test scripts, installed d3 sub-modules as runtime deps and typescript/esbuild/vitest as dev deps
2. tsconfig.json -- Strict TS config targeting ES2022 with bundler module resolution
3. vitest.config.ts -- jsdom environment with globals enabled
4. Placeholder source and test -- assets/src/heatmap.ts stub and passing test in assets/test/heatmap.test.ts
5. .gitignore -- Added .phpunit.result.cache

Verification Results

• npm run build -- Produces Resources/public/heatmap.js (537b minified)
• npm test -- 2 tests pass (570ms)
• npx tsc --noEmit -- No type errors

Deviations from Plan

Auto-fixed Issues

1. [Rule 2 - Missing] Added .phpunit.result.cache to .gitignore

• Found during: Task 4 verification
• Issue: PHPUnit result cache file was showing as untracked
• Fix: Added to .gitignore
• Files modified: .gitignore
