Putting this here because it's spoiler spec based on S2 trailers and the previews so far. I think that Project Daedalus is going to be the RA suit prototype. Section 31 has been working on a personal DASH suit. Remember in the beginning Discovery could only jump small distances? Seeing the RA jump into Kaminar's atmo in small multiple bursts made me think of how unusual an effect it was. So what if S31 was experimenting with a spore jump suit (in S1 Starfleet was working prototypes even though there was only one tardigrade to navigate) and somehow stumbled upon the time jumping properties too.
The bad AI from the future (either a mutated CONTROL or an alien AI which resents the Federation) sends the hacker program via altered probe to try to destroy S31 before it can complete the project maybe?
Eh, it's not perfect, but I like the idea of connecting the RA suit with the spore tech.
