This was 14lb mono to 30lb power pro.

This combo with a good knot will not break on the braid side.  Maybe counterfeit junk after all.

If it pulls loose it would still retain the clean cut you made when you cut the tag off.  If it breaks it will not look like a clean cut.  So a slipped knot will have a clean end; a break will have lots of micro fibers loose.

Agreed. You have to look closely to see that though. Unlike when a knot slips loose with mono or flouro, in which case the coiled up line is a dead give away.
