Just to confirm, Your Clan Needs You and the rulebook clan discount stack. We have a dispute over whether or not the 2 gold cost discount stacks with the 6 gold cost reduction.
Your Clan Needs You Battle: If any enemy units are at the current battlefield, choose your performing Personality in one of your provinces: Bring him into play at the current battlefield, paying all costs but paying 6 less Gold. After the battle ends, if he is in play, discard all his attachments and put him face up into one of your provinces, face-up, discarding any card there.
Clan discount: If a Personality has your Clan alignment, at any time you bring him into play, you may pay 2 less Gold for him to enter play. This is known as buying the Personality “with Clan discount.” It is not applied to Personalities who are created during the game (see Created Cards, p. 97).
Do they stack with the rulebook effect of discounting in clan personalities by 2 for a total discount of 8? Or does the -6 supplant the -2? Does the -6 replace the rulebook discount text or augment it. Card effects always override rulebook effects, but is this an override or an augmentation?

Yes, the two effects will "stack" for a total discount of 8G.
