Overview

FR-009: every entry explains itself.

A ledger row that records that a call was denied but not what denied it is the row you are holding during an incident, and it answers nothing. The gem's own recorder cannot write one — Entry validates the column — but a host-supplied recorder can, which is exactly the case this check covers.

Reeve::Checks::RulePresent.new(tool: InvoiceSearchTool, principal: alice).call
