It seems to me that openly invading a country is a rather unambiguous way to declare war. Compared to espionage, covert operations and such.

And the attempted assassinations of dissidents/defectors with nerve agents only available to one country seems a rather unambiguous way to declare it was a state-sanctioned hit, yet it was denied up and down.

As is this invasion portrayed as a 'special military operation', what distinction that actually is from an invasion is up to the rules lawyers, apparently.

They are not allowed to call it that in Russia. It's a "special operation".
