Relabel one diarized speaker track inside a recording or that recording's episode-of-one, without confirming identity, creating a SpeakerProfile, or enrolling/saving a voiceprint. Use this when the user asks to fix captions such as "Speaker 2 is Adrian" and wants future captioned exports from this recording to use the corrected name. This is rename-only: biometric voice memory and identity confirmation require a human web action in speaker review.

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.
