The temporal sequence of books, although as I said in my initial response, that is hard to determine (for example, is Job very old or relatively new?).
You asked if the subject is about knowledge or about discussion. I assumed that you would understand that revelation is assumed to a source of knowledge, not merely of discussion.
What we can see from the relatively few OT references to Satan is that direct references are scant before the exile. But by the time of the prophet Zechariah, writing soon after the return from exile in an apocalyptic style, Satan is represented as accusing the high priest Joshua, in the presence of “the angel of Yahweh,” and being told by the latter, “Yahweh rebuke you!”
This fits pretty neatly both into the OT Job scenario, and also that in NT Jude: in Zechariah’s apocalyptic visionary genre, Satan falsely accuses those whom God wants to bless, and yet retains some kind of status that allows him to be in the company of a mighty angel rather than lurking in hell, or somewhere. He also has sufficient status that even the (presumed) archangel leaves his rebuke in the hands of Yahweh himself, in the same way that Jude describes in the NT.
Now, exactly where that idea “came from” is speculative: it is said by academics to have been adopted from Babylonian ideas during the exile, but then the apocalyptic genre, quintessentially Jewish, which is the main vehicle for “angel discourse” both inside and outside Scripture, arose at the same time, so in my view it is unwise to be confident in outsourcing it.
What is clear is that both the canonical OT and the NT are far more restrained than the extra-canonical literature, in which whole hierarchies of angelic beings, good and evil, join in the fun: that maybe represents the “discussion” element in the inter-testamental period.
By the New Testament (and Jonathan will disagree here, judging from previous threads at PS, but I think found litttle support from the Christian commenters) only the Sadducees are, amongst the Jews, recorded as denying angels and devils altogether. Satan as the arch deceiver is viewed as a heavenly being finally defeated and evicted by the victory of Jesus. He has allies, described by Paul as “powers and principalities in the heavenly realms,” with influence over sinful human affairs at political and religious levels.
For that reason, antisupernaturalist scholars have suggested Paul is talking about “institutional evil,” and they are right - but he means that at more than a merely human level.
Once again, that link to geopolitics goes back at least as far as Daniel (if we discount 1 Chron 21), and is seen in spades in the final book of the New Testament.
