message SubscribeResponse {  string topic = 1;  int64 partition = 2;  int64 offset = 3;  int64 timestamp_ms = 4;  bytes payload = 5;}

partition and offset identify the source position. timestamp_ms records source time in Unix milliseconds.

For JSON output, parse payload as UTF-8 JSON.

See the decoded stream catalog, supported protocols, and production use cases.

Use the full program-shaped catalog when you need instructions and events beyond the curated feeds.
