This is interesting to say the least...
I have something on my plot (it loves my polytunnel) that looks very like your photos - lots of plants have leaves like that and a prostrate sprawl, but the arrangement of the flower buds/fruits is identical to your photo.
I would normally regard this as conclusive, but mine has a fairly pungent smell and a delicious rich "warm" taste somewhere between cress and rocket - but only in tiny quantities because otherwise the bitterness swamps everything else.
If anyone finds it I recommend you try a tiny leaf before you destroy something that could be as important as rocket in your kitchen.
I tentatively identified it as a Lepidium - probably L.didymum - lesser swine cress, which is closely related to the "greek cress" that appears in many seed catalogues. I assume pigs like it - I do!
There are photos very like yours on
https://www.naturespot.org.uk/species/lesser-swine-cress with closeups of the flower buds/fruits. It's difficult to see that stuff on your photo - whether your flower stems show buds or fruits - even more difficult to distinguish the double fruits but I think there is a related species that has singles - or at least looks more like singles.
It's may be that a slightly different species has no smell or flavour. Please ask a friend or neighbour to try a tiny leaf, because... I don't want to sound rude, but it's also possible (in these dark days) that you have recently recovered from Covid19. There is also a massive genetic variation in this area - I remember this demonstrated in a science lesson by a substance that only half the class could taste
at all.
Cheers.
