type Config struct {
	// Server is the APRS-IS host:port (required). Typical values are
	// "noam.aprs2.net:14580" or "rotate.aprs2.net:14580".
	Server string
	// StationCallsign is the resolved station identifier (required). The
	// iGate has no per-station override (per design D3: iGate login
	// identity and messaging identity are always the station callsign)
	// so callers resolve via ResolveStationCallsign and pass the result
	// in. The APRS-IS passcode is derived from this at login time via
	// callsign.APRSPasscode — not carried on Config.
	StationCallsign string
	// ServerFilter is the APRS-IS filter string passed at login time
	// (e.g. "m/100" for a 100km radius around the station).
	ServerFilter string
	// SoftwareName and SoftwareVersion appear in the login banner.
	SoftwareName    string
	SoftwareVersion string
	// Rules seeds the IS->RF filter engine.
	Rules []filters.Rule
	// TxChannel is the radio channel IS->RF frames are submitted on.
	TxChannel uint32
	// ChannelModes resolves Channel.Mode at TX time. When the iGate's
	// configured TxChannel is "packet"-mode, the IS->RF runtime gate
	// drops the frame and logs a Warn (see handleISLine). Nil = treat
	// every channel as ChannelModeAPRS (preserves the legacy
	// any-channel-does-anything behavior). Lookup errors are treated
	// as APRS-mode at the gate point (fail-open).
	ChannelModes configstore.ChannelModeLookup
	// Governor is the TX governor for IS->RF submissions. Required for
	// downlink; leave nil for IS->RF=disabled. Declared as the
	// canonical txgovernor.TxSink interface so tests can inject a
	// stub; *txgovernor.Governor satisfies it.
	Governor txgovernor.TxSink
	// SimulationMode starts with log-only APRS-IS sends when true.
	SimulationMode bool
	// Logger is optional; defaults to slog.Default().
	Logger *slog.Logger
	// Registry lets the iGate export its own Prometheus metrics into
	// graywolf's registry without needing pkg/metrics changes.
	Registry prometheus.Registerer
	// RfToIsHook is called after a packet has been successfully gated
	// from RF up to APRS-IS (or would have been, in simulation mode).
	// Optional. Used by the orchestrator to record a distinct
	// packetlog entry for the upload so it can be distinguished from
	// the raw RX entry.
	RfToIsHook func(pkt *aprs.DecodedAPRSPacket, line string)
	// IsRxHook is called for every packet successfully received from
	// APRS-IS, regardless of whether the local IS->RF filter engine
	// would allow it to be transmitted. Used to record IS-heard stations
	// in the packet log / station cache for map display, which must not
	// be coupled to the transmit-gating filter. Optional.
	IsRxHook func(pkt *aprs.DecodedAPRSPacket, line string)
	// LocalOrigin is an optional lookup for locally-originated messages.
	// When non-nil and SuppressLocalMessageReGate is true, the gateway
	// skips RF->IS gating for any message packet whose (source, msg_id)
	// is present in the ring — this prevents our own outbound messages
	// from being re-gated to APRS-IS after a digipeater repeats them
	// back onto RF.
	LocalOrigin LocalOriginRing
	// SuppressLocalMessageReGate enables the LocalOrigin consult step.
	// Defaults to true in Phase 5 wiring; operators can set false to
	// preserve legacy behavior (re-gate every packet).
