^Actually, the only thing is shows is Excalibur Umbra specifically was sentient, due to a different method they were seemingly experimenting with where as they infected the Dax soldiers they forced them to retain a memory, likely in hopes that this memory would prevent them from going feral like the others, like Rhino Prime who ended up going wild and eating some Orokin researchers through a gorey display of feral violence.

The only other case of Warframe sentience you might be able to mention is through the second dream where your Warframe breaks the War sticking inside them, but this is more likely the Operator gaining a little remote transference, an ability they fully learn in the War Within quest.

As for the commenter that mentioned Mirage and Gara for example, firstly these were likely Mirage Prime and Gara Prime, the original primes that gave up their lives but left the means necessary to rebuild them. Same for Inaros, the one in the story was likely Inaros Prime but due to the lack of the means of recreating him fully (aka void prime parts) we can only create the unprimed version for now.
