Audit an existing data dashboard, chart deck, or data visualization for accuracy, source integrity, denominator/population conflation, presentation simplicity, and neutral tone — then harden it before it is shared or published. Run this AFTER an initial dashboard/visualization has been built (not while scaffolding — use web-dev for that, which also covers accessibility). Triggers on requests like "review this dashboard," "is this chart honest/clear," "check the data and sources," "reduce cognitive load," "tighten before I share it." Produces a severity-ranked findings doc and applies fixes only on confirmation.
