Where in the EBT is sammā samādhi defined as 4 jhānas?

I’m going to go out on a limb to ask a silly question - where do the texts actually say that Right Concentration is the 4 Jhanas?

@samseva had been exploring this recently:

Is sammā-samādhi solely jhāna, and is jhāna required for the attainment of Nibbāna?

Edit 17 August 2020: @Samseva has asked me (@Brahmali) to add the following text, between the square brackets, as a header to the original post: [IMPORTANT: Please read this post, or take into consideration the following. This discussion, and its topic, in no way implies that “jhāna isn’t needed for the path of stream-entry/once-returner…" (or “the path as a whole”). It simply means that it’s not impossible for one to reach sakadāgāmimagga without jhāna… In a similar way that it’s not im…

I suspect you could make a clarificatory contribution there. For example, I’m looking at SN 56.11’s phrase:

Now this, bhikkhus, is the noble truth of suffering: birth is suffering, aging is suffering, illness is suffering, death is suffering; union with what is displeasing is suffering; separation from what is pleasing is suffering; not to get what one wants is suffering; in brief, the five aggregates subject to clinging are suffering.

This “in brief” seems to suggest that, of all the various sorts of suffering here, they are all included in the idea “the five aggregates subject to clinging” - all varieties of suffering are rooted in that clinging there.

Using that same structure, it seems to me that there are all sorts of samadhi on offer, but the ones that come together under the banner of “samma-” are all of them undergirded by jhana, in the same way that all suffering is undergirded by clinging.

You seem to suggest that this is incorrect; how so?
