Podrías or podías

Using poder in El pretérito Indefinido vs El pretérito Imperfecto (could in past actions)

Using poder to say could [do something] for polite requests and suggestions (conditional simple)

I was taught the same thing and now I'm confused, because my test result seems to be telling me that I could have used "podrías haber traido" a bottle of wine, when talking about an opportunity in the past that was missed.  My inclination is to stick with what I was originally taught, and be a little more wary of Kwiziq's guidance...unless anyone can direct me to another teaching resource that clarifies this more.  Many thanks.
