Module capabilities 

Shared capability bitmap constants for the v1 Hello/Negotiated exchange.

Hello.client_capabilities and Negotiated.server_capabilities carry a u64 bitmap. A capability is in effect only when both sides advertise it. Bit assignments are FROZEN once a release ships them — never reuse or renumber a bit (#228 frozen-forever commitments, #354 handoff tracker).

Constants

CAP_HANDLE_PASSING

Capability bit: the peer can participate in broker-to-backend connection handoff via platform handle passing (DuplicateHandle on Windows, SCM_RIGHTS on Unix).

Functions

handoff_transport_available

Whether this build carries a platform handle-passing transport at all.
