Gaining profiency in Shuriken, as not monk

[Zwordsman]

Howdy.

Does anyone know ways to gain proficiency to the Uncommon Martial Weapon Shuriken?

I am attempting to gain this as an Alchemist, because of the 0 "reload" detail, allowing for a throw build, as Darts. for some reason, despite being nearly the same size, require a draw action... which requires dipping into Rogue.

So. I see that the Weapon Proficiency feat gives you
"You gain the trained proficiency rank in all simple
weapons. If you were already trained in all simple weapons,
you become trained in all martial weapons."

Is this feat specific enough to override the Uncommon weapon section?
IF not...
Is there actually any way to gain proficiency with it?

It would be nice to take 1 general feat, instead of 2 class feats. Though Rogue Dedication isn't horrible, just pretty long way when I already want Fighter's Dedication + lv 2 ranged assist feat.

If you are trained in all martial weapons then you are trained in shuriken. The rarity comes in when you try to actually purchase some; being proficient does not AFAIK automatically give you access. You have to convince the GM it's appropriate for your character; I don't know of any feat/thing you could just take that would give you access.

Monks, for the record, would gain access by taking the Monastic Weaponry class feat, which says "You gain access to uncommon weapons with the monk trait".

Ah.
Hum. I guess they'd have to be self crafted.

which makes that goblin cheap junk crafting useful.
