My take is that the four truths only apply when suffering exists. If the first truth applies, the remaining truths apply.
That Gautama described a ten-fold path for the adept speaks to the existence of the first truth on occasion, even for those who have attained to “freedom” and “knowledge”.
In MN 70, Gautama described 7 different “(types of) persons existing in the world”. The first two had nothing further to be done through diligence, their cankers were completely destroyed, but the remaining five did have, their cankers being only partly destroyed if at all. The first person had abided in the “peaceful Deliverances”, the incorporeal jhanas, but was “freed both ways”. The third person had abided in the “peaceful Deliverances”, but was apparently not “freed both ways”. The second person was freed by “intuitive wisdom”.
All seven persons had “seen by means of wisdom”.
In MN 4, Gautama recounts directing his mind in the fourth rupa jhana to “the knowledge and recollection of former habitations”, to “the knowledge of the passing hence and arising of beings”, and to “the knowledge and destruction of the cankers”. The knowledge and destruction of the cankers involved both understanding as it really is the four truths, and understanding as it really is four similar truths about the cankers.
In SN 54.11, Gautama recommends the mindfulness described in SN 54.1 to both those aspiring to the “supreme sanctuary from the yoke” and to “those mendicants who are perfected”. Doesn’t sound like a one and done there.
If mindfulness is not one and done, then as in Maha Satipatthana (DN 22), there will be mindfulness of the four rupa jhanas, and of the elements of the path leading to the end of suffering.
Gautama said that seven days and seven nights of Satipatthana would result in “profound knowledge”, but how many are able to direct their minds as he did in the fourth jhana, to former habitations and the arising of beings (much less seeing as it really is the four truths and the cankers)?
You get the brass ring if you are freed and knowledge of that freedom arises, but in fact you remain on the carousel. Or as Ch’an master Yuanwu put it, “if you feel like stopping, then stop. Don’t ever think that you will be finished” (words to that effect, from Zen Letters tr. Cleary).
I’ll add that I don’t find Sariputta’s statements to be as consistent as Gautama’s, and so tend to disregard them, in spite of Gautama’s expressed confidence in them (which may or may not have been an addition, IMO).
