Rename the getLivePlaylist/getLiveSegment query param did -> streamer and resolve it to a DID: an alias or a Bluesky handle resolves via the atproto sync cache, a did:* passes through unchanged. The window stays keyed by DID, and the master playlist embeds the resolved DID in its sub-URLs so follow-up media/segment requests skip re-resolution and stay stable across a session. Lexicons updated (streamer param, no strict did format) + make lexicons regenerates the stubs, client types, and OpenAPI docs. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
