Unendorsed while acting/Endorsed reflectively: This is not so strange a failure mode as you are indicating. You take some action, which at the time you know isn’t right (execution failure). Later, you come up with some post-hoc justification for your actions. This is another failure mode to be aware of, affecting the postmortem.
Postmortems can have their own failure modes. We might disagree about the facts of what happened. We might have different perspectives on the context in which things happened. We might struggle to be honest with ourselves about our motivations at the time, or our analysis of past events is colored differently by information gained after the events—maybe giving us better insight, or maybe clouding over the original failure.
