Sometimes I finish a memory. No body saw me. Some yellow blip happen but that's it. I never pull out my sword.
I finish the memory but I do not know if my secondary objective is fulfilled or not. After a long time I saw that it's not.
How can we always check whether we have already been in combat or not or whether our secondary objective is fulfilled or not earlier?
For example, Memory 01: Black Bart's Gambit
I think I am not seen but that avoid combat objective is never fulfilled. What count as combat anyway? Sometimes soldiers see me, turn red, and I hide, and kill the guy silently. That still doesn't count as combat.

The secondary objective appears on screen for a short amount of time at the start of a mission, once it has faded you can review these in the 'Options' menu.
I found that if I failed a secondary objective, rather than appear but crossed out, it just disappeared altogether from any view (not the best UI design in my opinion).
My 'best practise' was to check the secondary objectives at the start of the mission, and check them fairly regularly throughout the playthrough of the mission to check that you haven't inadvertently failed the objective (as it's not always particularly obvious).
Having said that what @ReCaptcha has mentioned in his answer is correct - "Avoid combat" is the same as "Don't be detected" when within a 'restricted area' (those that appear as red on the mini-map), since the enemy immediately go into combat once they detect you.
