faster-whisper backend (lib/fw-stt.mjs, faster-whisper-server.py)
- Added faster-whisper as an alternative STT backend with word-level timestamps
- Select with
--stt faster-whisperflag onquery-demo.mjs - Python subprocess protocol: JSON lines over stdin/stdout,
ready\non startup - Sherpa-onnx VAD still used for segment detection; transcription goes to Python
Install script (install-faster-whisper.sh)
- Rewritten to use persistent build directory (
build/ctranslate2/) instead of tmpfs temp dir — cmake's incremental build now works across runs - Each step (clone, cmake build, Python bindings, faster-whisper) is skipped if already done
- Builds ctranslate2 C++ library from source against system CUDA 13 (PyPI wheel requires CUDA 12)
- Installs C++ library into venv so Python bindings find headers and library automatically
- Detects and removes PyPI ctranslate2 wheel (which bundles its own CUDA 12 library) before installing source-built bindings
- Fixed:

Bug fixes
pending-query.mjsalignment bug:new Int16Array(chunk.buffer, chunk.byteOffset, ...)threw on odd byte offsets from Node.js Buffer pool slices, silently killing audio-based timer resets and causing premature silence timeouts mid-sentence. Fixed by copying to aligned buffer whenbyteOffset % 2 !== 0.query-demo.mjsURL parsing:--debug-waveformwithout a value was grabbing the next flag (--stt) as the URL. Fixed by checking that the parsed value doesn't start with--.fw-stt.mjssilent fetch errors:_post_debugwas callingfetch().catch(() => {}), swallowing connection errors to the waveform viewer silently. Now logs failures.pending-query.mjsinstant dispatch timer leak: silence timer was not cleared on instant dispatch, causing double-submit. Fixed by clearing timer and resetting state in the instant dispatch path.
Global exception handling (query-demo.mjs)
- Added
process.on('uncaughtException')andprocess.on('unhandledRejection')handlers to surface hidden errors in stderr.
Command dispatch design (COMMAND-DISPATCH.md)
- Documented planned mode stack architecture with
check_parentrule, frame types, and dispatch targets
