 *   - a warm, OPEN, non-authenticating app socket already exists (never opens one);
 *   - the server advertised `capabilities.runQuery` on the authenticated ack;

 *   - the serialized frame fits the WS message limit.

 * "fall back to HTTP" - for every miss/refusal (no socket, no capability, identity
 * skew, oversized batch, the server's own `{ useHttp: true }` deferral, or any
 * timeout / disconnect / error frame). The rows are byte-identical to POST /queries,
