Sheet-qualified ranges are accepted (#30) — reported by @braklo. parse_range_string had no room for a sheet prefix, so Summary.D4:D6 and every variant were rejected outright and no Calc tool could address anything but the active sheet. Cross-sheet work had to route through switch_sheet, a stateful operation that moves the active sheet under the user, and a chart could not be built over data sitting on a data sheet — the ordinary workbook layout. All four syntaxes now resolve: Sheet1.A1:C5, 'Sheet One'.A1, Sheet1!A1, 'Sheet One'!A1. Supported by calc_read_range, calc_write_range, calc_clear_range, calc_comment and calc_chart; a prefix wins over sheet_name, and disagreeing between the two is an error rather than a silent choice
Sheet names are no longer upper-cased in errors (#30) — the parser upper-cased the whole reference, so a sheet called Summary was reported back as SUMMARY. Only the address part is normalised now, and an unknown sheet lists the ones that exist
Invalid Calc input no longer logs as an error — an unknown sheet or a malformed address is the caller's mistake, not a fault, and logging it at ERROR buried the real ones
