Errors

Error Format

{
  "type": "error",
  "channel": "CHANNEL_NAME",
  "message": "error description",
  "code": 400
}

Code	Message	Resolution
`400`	`given channel/mkt_id is unsupported`	Verify channel name and market identifier
`401`	`not authenticated`	Send auth message before subscribing to private channels

Treat auth failures as non-retryable until credentials/signature are refreshed.
Treat unsupported channel/market errors as configuration bugs, not transient failures.
Log full error payloads for diagnostics.
Reconnect with backoff only for transport-level failures.
