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

# scripts/parity-check.sh — run nisps_parity_check natively AND via WASM,
# then float32-diff the resulting blobs.
#
# Prerequisites:
# 1. scripts/build-cpp-tests.sh has run (need nisps_parity_check binary).
# 2. scripts/build-wasm.sh has run (need playground/public/nisps.{js,wasm}).
#
# This script can run either step on demand if the artifacts are missing.
# Skip auto-build with NISPS_PARITY_NO_BUILD=1.
#
# Exit codes:
# 0 — outputs match within 1e-5 absolute tolerance
# 1 — mismatch
# 2 — file/format error or missing artifacts
# 3 — build failure
