| # Finnish sanoTTS RC1 runtime contract | |
| Format: `roota.raw-fp16.v1` | |
| Input boundary: Piper phoneme IDs matching `piper-phoneme-config.json`. | |
| Sample rate: 22050 Hz | |
| Components: | |
| - duration: 135556 parameters | |
| - acoustic: 3490201 parameters | |
| - decoder: 730721 parameters | |
| - total: 4356478 parameters | |
| Acoustic config architecture: `calibrated` | |
| The calibrated acoustic wrapper uses the checkpoint config and its | |
| `depthwise_lowrank` output adapter. The latent boundary remains 192 channels. | |
| The tensor payload is a single contiguous little-endian fp16 blob. Every tensor | |
| has shape, byte offset, byte length, and SHA-256 in `manifest.json`. | |
