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

# Stream 11 verification pipeline.
|
||||
#
|
||||
# Two parallel jobs:
|
||||
# * cpp-tests — builds nisps host C++ tests, builds nisps.wasm, runs
|
||||
# the parity check, runs the lint script.
|
||||
# * playground-tests — typechecks the SolidJS playground, builds the
|
||||
# production bundle, runs Playwright e2e tests.
|
||||
#
|
||||
# Firmware compilation is NOT included in this workflow. Arduino-cli +
|
||||
# rp2040 board package add ~2 minutes per run, and the verification value
|
||||
# is low compared to the time cost; firmware build is documented as a
|
||||
# manual `scripts/build-firmware.sh` step in README.md / CLAUDE.md.

// engine.
|

//
|
||||
// What we're checking
|
||||
// -------------------
|
||||
// For each engine in the build, drive it with a SHORT, FIXED stimulus
|
||||
// (single-sample impulse at index 0) and capture a SHORT, FIXED response
|
||||
// length (256 samples). Compare the L+R energy curve and a handful of sample-
|
||||
// position checks against a baseline captured on a known-good build.
|
||||
//
|
||||
// We DON'T assert bit-perfect match — DSP code is bit-fragile under different
|
||||
// compilers and optimisation levels. We assert:
|
||||
// 1. Output is finite (no NaN/Inf).
|
||||
// 2. Output is bounded — engines don't blow up to >10 amplitude on a unit
|
||||
// impulse.
|
||||
// 3. Energy in a fixed window matches the baseline within a generous
|
||||
// tolerance (1e-3 absolute for energy, 1e-4 sample-wise).
|
||||
//
|
||||
// The baseline is captured ONCE, written next to this file as
|
||||
// `engine_impulse_baseline.bin`, then read back in subsequent runs. Set
|
||||
// NISPS_REGEN_BASELINE=1 to overwrite. Set NISPS_BASELINE_PATH=/some/path
|
||||
// to override the file location (useful for CI artifact upload).
|
||||
//
|
||||
// Per-engine setup
|
||||
// ----------------
|
||||
// Engines satisfying nisps::AudioEngine are:
|
||||
// PAFSynth, ChannelStrip, XIASRI, VerbFX, MEMLCelium, BreakOr, Elysiamorf,
|
||||
// Analysis, NoOp.
|
||||
//
|
||||
// PAFSynth is a generator (ignores input) — we still drive it with the
|
||||
// impulse stimulus and trust it to produce its idle output. BreakOr and
|
||||
// Elysiamorf are sequencers that emit on their own clock; we just care that
|
||||
// they don't crash. The impulse test is a smoke test, not a frequency-domain
|
||||
// validation.

// tests/cpp/ml_golden_vectors.cpp — fixed-seed regression test for the MLP.
|
||||
//
|
||||
// Why this exists
|
||||
// ---------------
|
||||
// The MLP class is deterministic given a fixed RNG seed. If anyone refactors
|
||||
// the forward pass, weight init, or RL noise injection, the *exact* output
|
||||
// vector for a known sequence of operations will change — and we want CI to
|
||||
// catch that loudly.
|
||||
//
|
||||
// What this captures
|
||||
// ------------------
|
||||
// 1. After construction with seed=42 (which calls draw_weights(1.0) inside
|
||||
// the constructor), we run inference at input (0.5, 0.5) and capture
|
||||
// every output.
|
||||
// 2. We call draw_weights(0.5) to re-randomise with mid-spread, infer, and
|
||||
// capture again.
|
||||
// 3. We add 4 simple input/label examples, train for 100 iterations at lr=0.5,
|
||||
// infer, and capture.
|
||||
// 4. We call move_weights(0.1, 0.3) (RL noise burst), infer, and capture.
|
||||
//
|
||||
// Test architecture
|
||||
// -----------------
|
||||
// MLP<2, 10, 10, 14, 33> — matches the firmware default for the PAF synth
|
||||
// mode (33 outputs). Exact dimensions don't matter much; we just need a
|
||||
// non-trivial output vector that exercises all four layers.
|
||||
//
|
||||
// Refreshing the golden file
|
||||
// --------------------------
|
||||
// Set NISPS_REGEN_GOLDEN=1 in the environment when running this binary. It
|
||||
// will print the current outputs in a copy-pasteable C-array literal to stdout
|
||||
// AND exit 0. Paste them into kExpectedStage[N] below and re-run with the env
|
||||
// var unset to verify.
|
||||
//
|
||||
// Tolerance
|
||||
// ---------
|
||||
// 1e-5 absolute. The MLP is float32 throughout; the only nondeterminism is
|
||||
// floating-point rounding order across optimization levels. We compile -O3 in
|
||||
// CMake and -O2 + AVX in Emscripten; the parity test catches drift between
|
||||
// builds. This test catches drift between commits.

// tests/cpp/parity_check.cpp — produces a deterministic blob the WASM build
|
||||
// must reproduce.
|
||||
//
|
||||
// Execution model
|
||||
// ---------------
|
||||
// This is a STANDALONE executable (not part of the gtest-style harness). It
|
||||
// runs a fixed sequence of MLP and engine operations, dumps the results to
|
||||
// `parity_native.bin`, and exits 0 if everything is finite. The companion
|
||||
// Node.js script (`tests/cpp/parity_wasm.mjs`) loads the WASM build of
|
||||
// nisps and runs the SAME sequence, dumping to `parity_wasm.bin`. The shell
|
||||
// script `scripts/parity-check.sh` then runs both and float32-diffs the
|
||||
// outputs with a 1e-5 tolerance.
|
||||
//
|
||||
// What we cover
|
||||
// -------------
|
||||
// 1. ML: seed=42, draw_weights(0.5), set_input(0.25, 0.75), process.
|
||||
// → 126 outputs + 12 weights sampled at known offsets.
|
||||
// 2. ML training: 3 examples added, train(0.3, 50, 0), capture loss + outputs.
|
||||
// 3. PAFSynth engine: seed-equivalent setup (params=0.5), 128-sample run on
|
||||
// silence, capture L+R averages.
|
||||
// 4. ChannelStrip engine: identical methodology.
|
||||
//
|
||||
// We use the EXACT SAME compile-time MLP architecture as the WASM build:
|
||||
// MLP<2, 10, 14, 18, 126>
|
||||
//
|
||||
// Output blob format
|
||||
// ------------------
|
||||
// uint32 magic = 'NPRT' = 0x5450524E
|
||||
// uint32 version = 1
|
||||
// uint32 n_floats
|
||||
// float32[n_floats] payload
|
||||
//
|
||||
// Stable order of payload (concatenated):
|
||||
// * 126 floats: outputs after stage 1 (post-process at (0.25, 0.75))
|
||||
// * 12 floats: weights sampled at fixed indices (see kProbeIdx below)
|
||||
// * 126 floats: outputs after stage 2 (post-train, re-process)
|
||||
// * 1 float : final training loss
|
||||
// * 2 floats: PAFSynth L mean, R mean (over 128 samples)
|
||||
// * 2 floats: ChannelStrip L mean, R mean
|
||||
//
|
||||
// Why not bit-perfect
|
||||
// -------------------
|
||||
// We compare to 1e-5 absolute. Native and WASM compile with the same source
|
||||
// and (mostly) the same flags, but FP order-of-summation can differ at -O3.
|
||||
// Anything bigger than 1e-5 means a true semantic divergence.

* Reads two binary blobs in the format produced by parity_check.cpp and
