w1n5t0n 3138701100 Stream 11: verification infrastructure (golden vectors + parity + lint + CI + Playwright migration)
Agent ran out of API credits before committing. Files staged + committed by orchestrator. Coverage:
- tests/cpp/ml_golden_vectors.cpp: fixed-seed regression tests for MLP determinism
- tests/cpp/engine_impulse.cpp: white-noise impulse responses with binary baseline
- tests/cpp/parity_check.cpp + parity_wasm.mjs + parity_diff.mjs: native vs WASM bit-equivalence
- scripts/build-cpp-tests.sh, lint-cpp.sh, parity-check.sh, run-all-tests.sh
- playground/tests/e2e/{ml-engine,modes,persistence,ui-interactions}.spec.ts (+helpers)
- .github/workflows/ci.yml

/**
* Mode-cycling smoke tests.
*
* For each registered mode, navigate to it and confirm:
* - The page renders without throwing an unhandled error.
* - No console errors fired.
* - The mode shell paints something visible.
*
* We don't enumerate per-mode controls here — that's the job of mode-
* specific specs. This spec exists to catch the obvious "mode X is broken
* after refactoring" regressions.
