A note in a CRM that says “two-option quotes close better” is a rumor. It might be true. Nobody can check if the decisions it came from, the evidence that tested it, and the later outcomes are gone.
Trustworthy memory lets someone follow a lesson back to the decision and its result. They can see the circumstances, examine the evidence, and judge whether it applies to the work in front of them.
This is why consequence memory is customer-controlled. A record this specific has competitive and regulatory weight. It must belong to the operator, export cleanly, and stand up to review.
