4) This eqenchanters mailing list message comments on the addition of Clarity in the late May 1999 patch:

Clarity was 100% added in the late May patch, I think it reasonable to assume Insight was added at the same time unless anyone has any other evidence.

Can confirm, the only Clarity spell shipped on the 1999 Yellow Disk was "Cassandra`s Chorus of Clarity"

The spell that later became Clarity was at index 174 as the spell "Ally", which added 400 faction. It was a direct upgrade to Benevolence.

That spell may not have been present on launch. though that info may have been lost to time:

Also Insight is lacking from the yellow disk spdat.eff that Nilbog sent me.

EQLizer spell list still has Ally:

spdat.eff dump from 5/20/99 still has Ally.

Found a post from the EQ_Magic mailing list after the May patch asking about a new level 29 ench spell that increased mana regen:
