Model sizes are hand-copied in four places and had drifted (fixed in #15): the table in docs/index.html (#models), the table in README.md, the model picker in demo/index.html, and the picker in examples/live-vad/index.html. examples/mp3/index.html has no sizes at all. Task: add scripts/model-sizes.ts (run with bun) that reads MODELS from src/types.ts and, for each model, sums the file sizes from https://huggingface.co/api/models/<hfId>/tree/main/onnx for the files actually loaded with hybrid quantization (encoder_model.onnx + decoder_model_merged_q4.onnx for Whisper; encoder_model_q4.onnx + decoder_model_merged_q4.onnx for Moonshine; include any *.onnx_data files), and prints a Markdown table. Optionally add the sizes to the examples/mp3 picker.
TranscribeStream.cancel() / TranscribePCMStream.cancel() and BrowserWhisper.dispose() exist in src/browser-whisper.ts (around lines 131, 304, 403) but are not mentioned in README.md or the API reference in docs/index.html (section #api). Task: add a short section with a usage snippet (e.g. cancelling a long transcription from a button, and calling dispose() when unmounting a component to terminate the workers) to both files.
src/types.ts defines the MODELS map (Hugging Face ids, hybridDtype, timestamp/language flags), but there is no test covering it (src/tests/ has chunker, errors, opfs-cache, resampler, webgpu, word-segments). Task: add src/tests/models.test.ts (bun test) asserting, for example: every ASRModel key has an onnx-community/... hfId every *_timestamped model has supportsWordTimestamps: true English-only models (moonshine-*, distil-whisper-small) have supportsLanguage: false Moonshine models have supportsTimestamps: false Run with bun test.
The only workflow today is .github/workflows/publish.yml, which runs typecheck/test/build only when a release is published. PRs get no automated checks. Task: add .github/workflows/ci.yml triggered on pull_request and push to main that: uses oven-sh/setup-bun@v2 runs bun install --frozen-lockfile, bun run typecheck, bun test, bun run build, bun run build:site You can copy the setup steps from publish.yml. See CONTRIBUTING.md for the commands.
