The words survived the split. The meanings did not. Kink, casual BDSM, and the relationship the Dominus Effect framework actually describes share a vocabulary, which is why they are so often mistaken for each other.
Spotting a warning sign is only half the skill. The other half is telling the difference between someone who is wrong for this and someone still learning it. The answer lies not in the fault itself but in its direction of travel, and in whether humility and honesty are present to correct it.
The theory is abundant, but it abandons you at the only question that matters: how do you actually start. This is the complete on-ramp, from the first conversation to a running dynamic, including the two rules that bind the Dominus harder than the slave and the after discussion that turns inexperience into the engine of everything that follows.
