What article states that a ferrule must be used with fine stranded wire?

There is no such article in the NEC.

The listing and manufacturer's instructions may so state, and Article 110-3 (I'm looking at a 1999 book at the moment) could be used as a reference/citation.

The fine stranded wire I've used is type W and G cables. The lugs on the breakers are not rated to accept that particular fine stranded cable.

I agree 110.3(B) is your reference.

Table 8 lists class B stranding.

Here are a couple articles relating to the subject. It appears that the lugs or connectors will have to be identified for use with the particular stranding.

The UL White Book also supports this.
