In chinese agama did buddha enter and remain in cessation of perception and feeling during paribbana?

So these narratives together suggest that the fourth jhana is originally considered more important for awakening than the cessation of perception and feeling.

It’s also interesting that the cessation of perception and feeling seems to always result in one realizing nibbana/the destruction of the taints upon exiting because it suggests that the common narrative of the Buddha’s awakening from the fourth jhana is incomplete or that he realized nibbana and then perhaps after discovered the cessation of perception and feeling. Or it is perhaps suggestive that the cessation of perception and feeling is some kind of later addition.

Recently, I attempted to start a thread which was intended to encompass questions like this. In that context, I find your comments interesting and would be interested to hear why you (or anyone else, because I do feel it is the default narrative) might feel the evidence suggestive of these particular conclusions rather than the other other way around (i.e., that, perhaps, the cessation of perception and feeling may have been considered more important for awakening than the fourth jhāna, or that the fourth jhāna rather than cessation might be some kind of later addition).
