	sapi_dual_channel.h
	"DualChannel" layer of ADR-020: wraps 1..N redundant sapi_dual_msgchannel_t links for fault-tolerant, always-send + bounded-ACK-wait delivery.
	sapi_dual_frames.h
	Layer-2 (DualChannel-owned) frame kind/header definitions for ADR-020 - shared between sapi_dual_channel.h and sapi_dual_negotiator.h so both can refer to the same wire structs without either depending on the other (sapi_dual_channel_t has no knowledge of sapi_dual_negotiator_t at all; the negotiator is the one-directional dependent - see ADR-020 section 3 and this module's own README note on ownership direction).
	sapi_dual_msgchannel.h
	"Channel" layer of ADR-020: one EN 50159-defended message channel over one already-open sapi_netlink_handle_t.
	sapi_dual_negotiator.h
	Dual state negotiator of ADR-020: decides sapi_dual_state_t for both this instance and its peer, driven over an attached sapi_dual_channel_t's STATE-frame flow.
	sapi_dual_types.h
	Shared enums for the sapi_dual module (ADR-020): dual-instance state negotiation and the redundant, EN 50159-defended messaging channel it can run over.
