​
versionNegotiation?

Defined in: client/multi-server.ts:61 Protocol version negotiation, applied identically to every server in the config (protocol revision 2026-07-28 and later). See ClientOptions.versionNegotiation on the single-server Client — same semantics, just applied per sub-client here since each connected server negotiates its own era independently. Default { mode: 'auto' }: each sub-client probes its server once and falls back to legacy when the server offers no modern era; { mode: 'legacy' } opts every connection out of the probe.
