App-only read of precomputed absolute-scale audio facts for source-time ranges already projected into an Episode timeline. Returns sample peak and RMS in tenths of dBFS plus EBU R128 short-term loudness in tenths of LUFS. Sources must belong to the named Episode graph. Resolution is selected from durable multiresolution evidence using pixels_per_second; this call never decodes media. A range with status analyzing has scheduled or coalesced an idempotent background backfill and may be retried after retry_after_ms. Status unavailable is terminal for this read, includes a reason, and does not schedule analysis or promise a retry. Status no_audio means accepted evidence found no audio; it is distinct from unavailable measurements.

The JSON blocks below are the exact MCP descriptor projections served by Rails for the named profiles at capture time. Security schemes and resource URIs may vary by connected host.
