- Fix race condition: pass return_timestamps as parameter instead of mutating shared state - Remove /local/transcriptions endpoint (path traversal vulnerability) - Add timeout=30 and URL scheme validation to prevent SSRF - Add temp file cleanup via try/finally in all route handlers - AsyncTaskManager: add threading.Lock and TTL cleanup for completed tasks - Change audio_rate to 16000 (matches Whisper's expected sample rate) - Extract filename from URL via Content-Disposition/path - Detect base64 audio format via python-magic - Fix response_size_bytes to use json.dumps instead of str() - Move scipy import to module level - Clamp temperature to [0.0, 1.0] - Deduplicate _load_model() code - Fix docstrings, README structure, typo, log level Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
