Function attachReferencesChain

internal/agent/hitl_api.go:156–165

attachReferencesChain rebuilds the References chain on a HITL-approved SendRequest by looking up the parent inbound's raw message via email_message_id. Required because the pending-outbound row only persists the parent's Message-ID, not its raw message — without re-deriving here, HITL-protected repl

(ctx context.Context, store hitlInboundLookup, agentID string, req *outbound.SendRequest)

// than refusing the send. Callers must keep ReplyToMessageID populated
// regardless; only References is filled in here.
func attachReferencesChain(ctx context.Context, store hitlInboundLookup, agentID string, req *outbound.SendRequest) {
	if req.ReplyToMessageID == "" {
		return
	}
	inbound, err := store.GetInboundByEmailMessageID(ctx, agentID, req.ReplyToMessageID)
	if err != nil || inbound == nil {
		return
	}
	req.References = outbound.BuildReferencesChain(inbound.RawMessage, req.ReplyToMessageID)
}

// hitlInboundLookup is the narrow store contract attachReferencesChain
// needs. Defined as an interface so tests can stub it without spinning
