What proportion of evidence links remain accessible to an authorized reviewer over time, and which failure modes appear? The study is designed as a descriptive operating review, not as proof that an offshore location, staffing model, or individual caused an outcome. Its practical use is to locate review friction and formulate follow-up questions before changing access, staffing, or approval policy.
For measuring evidence link decay in bookkeeping workpapers, the intended decision is whether a process owner should clarify evidence requirements, rebalance a queue, change an escalation threshold, or test a specific control more directly. The analysis should never be used as an automated employee score or as a substitute for accounting judgment.
