با استفاده از این label می تونیم برای این checkbox بیای و label تعیین کنی

Not clear whether it could (easily) be used "standalone" — without any child checkboxes.

I guess technically what I've been calling tri-state should be more generically called mixed-state? But I have so far not seen that term used anywhere else. Even web standard, https://www.w3.org/TR/wai-aria-practices-1.1/#checkbox, mentions tri-state but not "mixed-state".

Interesting that indeterminate is after the determinate. I would tend to think of the indeterminate state as being first, since that is the default/initial state of a form control like checkbox or radio button. Oh well...

Couldn't find any web pages referencing this page. Why not? How did I even find it?

So the main thing this gives us is a way to set indeterminate property of input via an indeterminate property?

This is misnamed. Doesn't actually give us a tri-state checkbox. Just a binary checkbox.
