variables: auxiliary machine-reference variables resolve since #1236; recount (64 keys, 63 variables, add width/height/depth to the missing list). Drop merged #1205, #1212 pending notices
variables: recount the element information keys against master The page said an element carries 57 information keys, that three are absent from the braced-variable list by design, and that four more are absent with no apparent reason. Measured against master 3cbb93075 that is now out of date. QETInformation::elementInfoKeys() lists 61 keys; 59 braced variables are recognised in AssignVariables::replaceVariable(). Eleven keys have no braced variable: formula and xref, absent by design, plus nine more. Five of those nine -- category, model, notes, voltage_rating and current_rating -- arrived with the smart-device metadata fields and were never added to replaceVariable(). The four machine_manufacturer_reference_auxiliary variants the page already documented have been missing for longer. exclude_from_bom is dropped from the "absent by design" list: it is not in elementInfoKeys() at all, so it was never a candidate. Applied to the English, French and German pages, which carried the same figures. Each now records what the earlier numbers were and that they were correct when written -- the drift is the argument for counting from the source rather than maintaining the list by hand.
Document the variable and formula language, all five dialects of it There is no single %-variable language in QET: element labels, conductor texts, the folio field, title block cells and cross-reference labels each resolve a different set, and a variable that works in one is left as literal text in another with no error. The folio field is the sharpest case -- it understands %autonum, %id and %total and nothing else, so the %f and %{...} people reach for there print verbatim on every folio. Also records two things the code says that nothing else documents: - %f and %F are not interchangeable. %f is the folio index; %F inserts the folio *field*, which defaults to "%id/%total" and so renders "3/12". It works only because %F is expanded before %id and %total in the same pass. - AssignVariables::replaceVariable() is a hard-coded list, not a lookup over elementInfoKeys(). Three omissions are deliberate (formula, xref, exclude_from_bom) but machine_manufacturer_reference_auxiliary1..4 are simply missing: the fields exist and can be filled in, the plain machine_manufacturer_reference resolves, and the four auxiliary variants stay on the drawing as literal text.
