"I see no evidence of this reactionary bourgeois character, aka capital's high priests, capitalists meaningfully penetrating China's people's government as you describe."
The Chinese bourgeoisie has deeply penetrated China's "people's" government, both metaphorically and literally. It is no secret that a large portion of the people who make up the Chinese parliament are millionaires and billionaires, most others are petite-bourgeois, and only some are Proletarians. The milionaires and billionaires in the Chinese government are by far the most powerful, they form cliques with their fellow bourgeois, and own a massive amont of banking capital. In short, the Chinese government has long-since been subverted by Capitalist interests.
"Consider South Korea and Japan. Two countries who are described very well by the same shades of paint as what you use above, wisconcom. These countries are little more than junior partners in the amerikan imperialist firm. Such is the success of capital penetration there and there."
Correct, South Korea and Japan are merely USA satellite-states and economic colonies. This, however, does not change the fact that imperialists can have rival imperialists, like during the First World War for example. It is simply the case that China was able to form its own Capitalist-bloc, where Chinese bourgeois are free to exploit.
"Over and over, I see evidence in both the global south and bourgeois north reporting that the dictatorship of the proletariat in China is strong. Strong enough to discipline unruly capital and keep its MCM cycle thoroughly subordinate to the needs of the dotp and its signifier, the cpc. Bourgeois media are terrified by the Chinese. And for good reason as noted in the Redsails article. There is a clear qualitative leap in how capital's various ideologies treat the behavior of the mightiest member of the 5 flowers."
What source is doing this reporting? As to the part where you talk about business cycles, the reason why China does not as badly suffer from them as the West does is not because they are a Proletarian Dictatorship, but simply due to their particular economic position. China has had access to a massive labour market and work force; if one market crashes, they can simply sell goods to a new one.
The reason why the Western media dislikes China is not because it is Socialist, but, as I have already talked about, it is simply a rival imperialist to the US-EU bloc. Why would you trust what the Western-media has to say about Socialism or Marxism anyways? Many Western "news" sources, particularly those in the USA, call things such as Covid-mandates "Communism", are you really going to trust them on this matter?
"Considering that the following two dictatorships are mutually exclusive, where is your line wisconcom? At what moment, at what year, do you believe China's dotp broke down and was replaced by a dictatorship of the bourgeois?"
The People's Republic of China is a bourgeois-revisionist state, from even the very start of Mao's leadership of the Communist Party, it already showed signs of Revisionism: be it with its class-collaboration, bourgeois nationalism, and usage of the petite-bourgeoisie. By Deng Xiaping's leadership, starting in the 1970's, it had firmly become Revisionist and State Capitalist.
