Eleven settings the invoice and bill workflow reads: the number prefix and
first number, default terms, payment methods with their bank details and
QR links, a footer, the unsent and reminder day counts, the bill reminder
and discount-warning day counts, and the company's email and website that
the seller snapshot prints.
Three new kinds keep them exact: a count is a positive whole number, terms
are canonicalized through Terms so "net 30" is stored once as "Net 30"
(B-39), and a payment method list admits at most eight methods whose lines
are at most 120 characters. A routing number is nine digits, so an ach or
wire method's bank-detail lines are the one text exempt from the full-TIN
check (A-3); every other text in a method is scanned.
The keys need the documents_v2 feature (D-52): an older version doesn't
know them, and the settings replay refuses an unknown key as newer. The
constant, the known-features entry and the gate test land with this slice
(its 8.0.6 work); S4.3 adds the document write call sites and must not
redeclare them.
A settings file now exports the [invoicing] and [bills] tables, a payment
method as an inline table (never a [[payment_methods]] section that would
land outside its table), and imports them back to the same values. The
unknown-key test uses fax instead of website, which is now a setting.
