Carissa should be told that she needs 2x +6/+6/+4 headbands and 30 Wishes, where the second portion of those are for Keltham as part of a seduction plan she'll rederive next time she's fully augmented, but though Carissa shouldn't be told it during negotiations, you can step in and tell her it's really okay to settle at anything down to 1x +6/+6 and 10 Wishes, without which Carissa actually will walk out on them and see if she can become more valuable before selling.
Headbands + Wishes for augmentation. Can't beat augmented Keltham with much stupider Carissa, tropes say equals. Wishes used to square payment for Cheliax's spellsilver progress, Keltham quoted 200k for a Wish scroll, can get arbitrator to agree on headband and Hell-Wish prices anchored on that. He might be doing something risky with Wishes, strongly prefer ambiguity interpreted by Hell than by other sources. Do not give Carissa Wish-augmentation immediately. Headband easier to take off if anything goes wrong and less-augmented Carissa safer to closely monitor (close monitoring will be necessary, suspect for INT 29 Carissa only Gorthoklek can do it).
And the rest of the letter is already written.
Objection: this bankrupts Cheliax. I have a solution in mind. Want to own all PL souls as a personal vanity; it's the first thing I asked Abarco for when commanded by Hell. Think I should be permitted, if in Hell's interests, to repurchase souls sold in Cheliax at their spellsilver-denominated prices from the original sale though we can now produce spellsilver more cheaply, freeing up budget for my Wishes and headbands and for future soul sales. Would also like to own everyone save you + Majestrix who ever read my mind, if the approach goes through at all, but this is a vanity not a priority.
Objection: probably a traitor's plot. Could trivially have suicided for rez in Osirion, or sought divine attention, or Geased my loyalists.
Objection: then why wipe memory. Think the Carissa who stands before you is more valuable in the eyes of Hell and in her own eyes. Want to be the most valuable version of myself. Think Asmodeus's instruction to come to him without thought of other choices is important, and am no longer able to do so. Don't want to be distracted by fear of losing my curiosity/etc while selling my soul. Slightly worried further revelations following from these ones really would have broken my loyalty.

And in the corrigibility notes:
Devils shouldn't have sufficiently strongly-held priorities they'll pull out any stops to achieve; here's a sketch of why.
Devils should prefer plans that are not weird (Carissa is aware that in this respect a crippled beggar is closer to Asmodeus than she is). Here's a sketch of why.
Is that all, is that enough -
- oh, and Aspexia will ask Abrogail. She could write a letter optimized for persuasiveness to Abrogail but it'd look different - she'll just have to gamble - and add one Abrogail-optimized line at the end where there's space for it -
