Learned generator composition

src/models/Invoke-KokoroLearnedGenerator.ps1 composes the configured two-stage Generator.forward after the harmonic STFT. Its input contract is batch-one decoder features, the 22-channel harmonic spectrum, style, and named weight vectors. Invoke-KokoroGenerator.ps1 connects the F0-driven harmonic prelude to this learned stage. It applies leaky ReLU, the 10x and 6x weight-normalized transposed convolutions, source convolutions and AdaIN residual blocks, the left reflection pad on stage two, three parallel AdaIN residual blocks per stage, their average, post projection, and the existing 20/5 inverse-STFT PCM head. Parameter names follow the stock checkpoint's generator suffixes.

Source identity: Kokoro dfb907a02bba8152ca444717ca5d78747ccb4bec, kokoro/istftnet.py (Generator.__init__ and Generator.forward), and lib/kokoro-v1_0.config.json. Each primitive retains its own source and shape gate. This composition contains no QNN, Python, ONNX, LLVM, or Roslyn execution path.

Executable gate:

pwsh -NoProfile -File tools/Test-KokoroLearnedGenerator.ps1

Result: pass. The gate exercises both stages with bounded synthetic tensors, zero and nonzero projection paths, 61 spectral frames and 300 PCM samples from one input frame, a deterministic two-F0-frame harmonic-source-to-PCM path with 600 samples, finite PCM, and rejection of an absent required weight. The same gate with -CheckpointPath build/cache/kokoro-v1_0.pth also passes: the checkpoint matches the pinned length and SHA-256, and all 303 declared generator tensors satisfy exact shape, FP32 dtype, contiguous stride, and finite-value checks. Read-KokoroGeneratorWeights.ps1 supplies the named arrays without a Python or PyTorch runtime. The existing Test-KokoroSineSource.ps1, Test-KokoroNoiseConv1d.ps1, and Test-KokoroWeightNormTransposeConv1d.ps1 also pass with this verified checkpoint. The transposed-convolution check is a slow scalar reference, not a device-performance measurement.

It does not compare numerical output against a stock-weight oracle, connect the acoustic branches to the decoder and generator, measure a normal-length phrase, run on a phone, or establish audible speech. Those are separate promotion gates.
