The ai-bookkeeper README said LBB's headerless Amazon credit-card CSV (card number first, no header, ; separated) read zero rows. Running the sample layout through readStatement today reads every row, with dates, decimal-comma amounts and descriptions right, through the generic column inference. Nothing guarded that, so it now has a test (rows made up from the layout of ofxstatement-bubbas's sample), and the README line is corrected.
Separately, the 2027 IRS inflation-adjustment revenue procedure is still not on irs.gov/pub/irs-drop as of today (rp-26-35 through 42 return 404; rp-26-26 is the ACA premium-credit indexing, not the income-tax tables), so estimate keeps warning for 2027. Estimates only, not tax advice.
