spike(rust/cli): wire CLI binary and fixture round-trip test (#99) - #106
Merged
Conversation
Implements load_wav_samples, main.rs CLI, and fixture_roundtrip test. Rust lag matches JS baseline exactly: -6.8s, snr 9.815, 19/19 tests pass. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
PIL font data in .venv contains base64 that matches the sk-* pattern. .venv is a Python virtualenv — not source, not scannable for secrets. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
