No, it isn't corydalis nobilis. Corydalis nobilis is clearly not evergreen, is not so fast to flower from seed, is far more "coarse" plant, both in flower and leaves. May be you live in very warm place, but C. nobilis flowers clearly AFTER C. solida.
Your plant is a delicacy. I'm not an expert at all - may be Corydalis speciosa? While I don't have it, it is a biennial - so it can be both evergreen and be in continuous growth like many biennials, depending on weather. It is also consistent with your 2-years-old seedling being in flower.
I have C. nobilis. It is OK, but large, comparatively little flowers, short flowering time (fades quickly) and the flowers are not really bright yellow. Lots of seeds. Looks best while sprouting when leaves and flower stems form a compressed elegant cluster and olive green in colour. It later fades to ordinary green. Still worth having if you have room for it. Hardy, long lived, tolerant to summer drought (it is dormant by that time).
If you want seeds, no problem. I will send you PM. I have too many seeds and I do not want more plants - I spread them in the neighbourhood. So why not to send to you??
Here some pics of true C. nobilis:

Unfortunately, I cannot find a picture with flowers now.
