}Venue wall clock
Venue wall clock in nanoseconds since the Unix epoch,
the same integer domain as record header ts and round open_ts. No
query params. Clients measure clock offset with Cristian’s algorithm:
offset = server_time − (t0 + t1) / 2 — equivalently server time plus
half the round-trip — then add that offset to the local wall clock.

The public API key (alphanumeric access_key string).
Request timestamp, Unix milliseconds (decimal). ±5000 ms replay window.
base64(HMAC-SHA256(secret, "timestamp\nMETHOD\npath?query\nbody")). For the WS handshake the body is empty and the path is /v1/ws.
