An LP cannot meaningfully audit "we use a productivity SaaS suite." The audit surface is in the wrong layer. Productivity tools log who did what; they do not log why the partner concluded what they concluded.
An LP can audit a Defensible Audit Log. Every Clarity Score is reconstructible from citation-grade evidence; every Kill Shot ties to a specific structural finding; every brittle assumption is mapped to its dependency in the underlying narrative. The artifact is the audit, not the workflow.
That is the structural reason a fund cannot satisfy modern fiduciary expectations with a stack of productivity software, no matter how AI-enhanced. The expectation is moving toward a reconstructible decision trail, and only judgment infrastructure produces one.
