audio/mpeg was hardcoded at both points call audio is written and served, from back when the node produced nothing but 16 kbps MP3. It now uploads FLAC, and a browser will not play a FLAC body labelled audio/mpeg. storage.py grows one extension -> Content-Type map, used by the GCS upload and by /media. Keyed off the object's real extension, so every existing .mp3 recording keeps working with no migration -- and _safe_audio_filename already accepted .flac, so object naming needed nothing. Also flags what this costs: /media sends the whole body with Accept-Ranges: none, which was fine at ~60 KB per call and is not fine at ~1.3 MB/min. Noted at the header and in DEFERRED.md, whose stated reason for deferring Range support was the old file size. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
