K (frontend-tests.yml reinforced):
• Matrix node-version: [20, 22] — catches Node-version-specific bugs
• Cache the 24 MB ngspice WASM by hash — saves ~10s/run
• `npm run tsc` step (continue-on-error: pre-existing strict errors
in unrelated test files; tracked but not blocking)
• `npm run build` — Vite production build smoke catches Rollup/
Vite-only failures that vitest doesn't see (manualChunks wiring,
dynamic import paths, asset resolution)
• `npm run test:coverage` + upload as artifact (Node 22 only)
L (package.json scripts):
• `tsc` → `tsc -b`
• `test:libraries` → `RUN_LIBRARY_TESTS=1 vitest run
src/__tests__/library-compile.integration.test.ts`
I (library-compile nightly):
• New `.github/workflows/library-compile.yml` — 5 AM UTC cron +
workflow_dispatch. Not on PRs (slow + external deps).
• Sets up arduino-cli + caches `~/.arduino15` cores (avr, esp32,
rp2040 — ~500 MB).
• New `library-compile.integration.test.ts` — iterates every
example with `code` + `libraries` + a known FQBN. For each:
arduino-cli lib install → write .ino → arduino-cli compile.
7 examples currently match (epaper-displays).
• Gated behind RUN_LIBRARY_TESTS=1; default vitest skips the file.
Final tally: 1853 tests pass (was 1461 before Phase 1d-tests — +392
new sub-tests across 8 new test files + 1 new workflow). Vite build
green (2.68 MB main chunk, unchanged).
