Recognized by sight: Discussion with N. Siegel – but the reddish-staining reminded me of C. cyanites, which is larger, bluer, and a bit darker red-staining. This seems more pinkish-magenta.

More viscid cap (usually greasy at most in blewits), traces of cortina on stipe covered in some rusty spores (lacking in blewits), lack of fuzzy lilac mycelium around stipe base (often but not always present on blewits), even gill edges (frequently serrate or eroded on blewits), lack of pale pruinosity on stipe (often but not always present on blewits). Reddish staining never shown by blewits.

Spore print would be rusty brown

you ask such pertinent questions. I overlooked that photo, and no, that’s not a feature of C. griseoviolaceus. I made the call mostly on your matching obs, but now think even it is too colorful (violet with orangish gluten) for griseoviolaceus.

Question about staining

as you can see in the lower photo, there is reddish-pink staining after a few minutes (when cut/rubbed).
This reminds me of _C. cyanites – I am not familiar with C. griseoviolaceus – is this typical?
