Inspectable example
Synthetic price list: a page-by-page row count that finds two mistakes a matching total hides
An invented three-page price list shows why rows are counted per page. A first extraction matches on the total, 14 of 14, while page 1 is a row short and page 2 has an extra row.
Inspectable example
Synthetic merged-cell report flattened: nine rows in, five records out, every total reconciled
An invented printed-style sales report with merged region labels, subtotal rows and a spacer becomes a flat five-record table, with a reconciliation showing 9 original rows = 5 records + 4 removed.
Inspectable example
Synthetic quotation: why the same three lines total 4.38 or 4.39 depending on the rounding rule
Three invented lines of 1.30 plus a 12.5 per cent add-on give 4.38 if the add-on is rounded per line and 4.39 if it is rounded on the total. The rule must be written down.
Inspectable example
Synthetic rename manifest: three clean renames with matching checksums and four held names
An invented seven-file folder shows a dry run and a manifest with a row for every file, with three renamed files whose checksums match, and four held, a pair of names that differ only in letter case, a reserved device name and a name ending in a period, all listed, not guessed.
Inspectable example
Synthetic date column: which rows a rule can settle, and which must stay on the ambiguity list
Nine invented entries show day-first and month-first typing, a two-digit year, a row where only one reading is possible, an impossible date and a four-year shift, with the decision and reason for each.
Inspectable example
Synthetic invoice reconciliation: identical net lines, two different tax totals
Three invented small-value lines show how line-level and invoice-level tax rounding can disagree even when net values and line counts match.
Inspectable example
Synthetic invoice retry matrix: source operation, attempt and target draft are different IDs
Concrete made-up references specify when a retry retains one target draft and when changed contents, a second organisation or multiple matches need a separate decision.
