fix(realtime): use prairie.* WebSocket subprotocols and ticket prefix - #31
Merged
Merged
Conversation
The server's API v2 sync (prairie-server#183) renames every silo.* realtime identifier to prairie.*, matching prairie-apple: prairie.playback-control.v2, prairie.events.v2, prairie.room.v2 and the prairie.ticket.<ticket> offer. Android still offered the silo.* names, so the server would refuse the upgrade. The vendored v2 fixture index also carries the renamed X-Prairie-Client headers. Merge together with prairie-server#183. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Release this client only with prairie-server#183.
A mixed deployment can reject every affected WebSocket upgrade. Deploy the matching server revision before this client, or make the server accept both identifier sets during rollout. This applies to prairie.playback-control.v2, prairie.room.v2, prairie.events.v2, and the prairie.ticket. prefix.

Renames the realtime WebSocket identifiers Android offers from
silo.*toprairie.*, so they match prairie-server once Prairie-Server/prairie-server#183 (the upstream API v2 sync) lands, and match prairie-apple, which already uses these names.silo.playback-control.v2prairie.playback-control.v2silo.events.v2prairie.events.v2silo.room.v2prairie.room.v2silo.ticket.<ticket>prairie.ticket.<ticket>The vendored v2 fixture index also changes
X-Silo-Client/X-Silo-Client-Versionto theX-Prairie-*names the server fixtures now use.Merge this together with prairie-server#183. Before that PR merges, the server still expects the old names, and after it merges, an app without this change cannot open playback-control, events or Watch Party sockets.
