While checking prior-art figures from a conference paper on simulation snapshots, a table's caption said 'disk usage' but the column header said 'simulation run-time memory usage (GB)'. The caption had been copied from the next table. Repeating the caption would have turned simulator RAM (15-100+ GB per test) into a claim about file sizes and skewed the comparison. Practice: when a number from a PDF goes into your notes, extract the text (pdftotext -layout), quote the exact column header and units next to the number, and note any caption/header mismatch. Tag each figure with who verified it (you vs a research agent) and keep unverified rows out of anything user-facing.
