The landed Terms::parse reads a date chrono reads and prints it padded, so
"Due 2026-1-5" is one value with "Due 2026-01-05", not a refusal. The
settings key still keeps one spelling; the test now asserts that
canonicalization instead of refusing the short form.
A customer's email is copied onto an invoice's bill-to snapshot at issue,
and a party's default terms (one as our customer, one as our vendor) are
the fallback a document's due date takes when the document itself names
none (A-13, rules.md B-39). Both are journaled as party.updated facts and
guarded by documents_v2: in books that have not declared it the write is
refused with the upgrade remedy and journaling nothing, and replay gives
the same directory back.
An email must be one plain address: one @, no spaces, no full TIN (the
party text rule already refuses nine digits). Terms are typed and already
canonical, so there is no second spelling to check. A party.updated naming
a field this version does not know is now NewerJournal, never corrupt
(B-27): an older version must say update, not damage; a known field with a
malformed value is still corrupt.
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.
Settings, conventions (posting templates, approval rules, policies,
close steps, calendar, mappings, notes), decisions, open items and
entry approvals are journal events (journal format 2). Books that keep
their settings never read wanderbooks.toml or config.json; the server
and the viewer take the vault key from --vault-key-file instead.
books.import_settings moves a settings file in once, exactly as the
server reads it. Approval rules, when enforced, gate every posting
path. Replay refuses what it can't read as newer, never as corrupt.
Lean: a record changes no figure. Mutation on the whole diff: every
survivor killed by a test but two equivalent (docs/testing.md). The
Company page says a late open item is overdue in words, not colour
alone.
