Every report a CPA expects, laid out the way US small-business books
read (QuickBooks as the reference):
- Exports: books.export gains general_ledger (by account, running
balances, splits), general_journal (the entry-ordered listing, which
the CPA package used to mislabel "general ledger"; alias journal),
members_equity, and trial_balance as of a date, in xlsx/csv/json, and
PDF for all five statements (P&L, balance sheet, cash flow, trial
balance, members' equity). books.trial_balance takes as_of.
- CPA package: every statement as PDF and XLSX, plus the general ledger
and general journal, all for the fiscal year to date.
- Layout (ledger-import::report): multi-column statements (Total;
Debit/Credit; one column per member plus Total), "$" on subtotals and
totals, a rule above every sum (none over an empty section), a double
rule under statement totals, zero as 0.00, negatives in parentheses
with the closing paren hanging so decimal points align.
- Terms: "Net income (loss)"; for a multi-member LLC, "Members' equity",
member contributions and distributions named in the cash flow, and the
balance sheet splitting retained earnings (the Retained Earnings
account plus earnings not yet closed from earlier years) from the
fiscal year's net income (loss); the cash flow's "Adjustments to
reconcile net income (loss) to net cash from operating activities" and
"Net increase (decrease) in cash".
- PDF: Inter replaces the typst-assets serif fonts (bundled, SIL OFL 1.1,
license in fonts/; from the official v4.1 release), centered title
block, column-header row, full-width rules, footer "Accrual basis ·
Prepared <date> · Journal seq N" with page numbers. Amounts on total
rows stay regular weight so bold figures can't leave the decimal
column. typst-assets dependency removed.
- XLSX: centered title block, header row, Excel accounting formats with
"$" attached on sums, general ledger and general journal workbooks.
- Config: wanderbooks.toml [[company.members]] (name, share "50%" or
"0.5", capital_account; shares must total 100%) and [books]
accounting_basis (accrual | cash).
- Core: RETAINED_EARNINGS_CODE names the "3999" that period close uses.
- Fix: "today" is local time, not UTC; in US evenings UTC is tomorrow,
so reports defaulting to "through today" included the next day and
footers carried the wrong date.
Tests: layout (currency and rule placement, retained earnings vs. this
year's net income for a member LLC, footer text); exact template data;
deterministic PDFs; config parsing (members, shares, basis); stdio:
trial balance as of, February general ledger (beginning 1,004.00, splits,
ending 1,003.50), members' equity (contributions 1,000.00, net income
3.50, ending 1,003.50), members' equity PDF, the CPA package's ten files.

Zero warnings from `cargo clippy --workspace --all-targets`, which is now
a hard rule rather than "clean except pre-existing":
- ChartOfAccounts::add takes the Account it registers instead of eight
loose parameters (too_many_arguments); Ledger::add_account builds it.
Same validation, same errors.
- close_period tool: collapse the nested if-let into a let chain.
- iif.rs docs: the IIF layout example shows tabs as `\t` instead of
literal tab characters (tabs_in_doc_comments).
- Tests: drop an unused binding; assert! instead of assert_eq! against a
literal bool.

The engine only had life-of-ledger P&L and balance sheet totals, so every
export labeled with a date range or as-of date (PDF, XLSX, CPA package)
printed all-time numbers under that label. Core now has:
- profit_and_loss_for_period(start, end, class?) and
balance_sheet_as_of(as_of), each with a line per account
(StatementLine: code, name, normal-side amount) and exact totals.
- Ledger::closing_entry_ids(). Period statements exclude closing entries.
A close (Dr revenue / Cr expense / net to Retained Earnings, dated at
period end) moves earnings; it doesn't earn or spend. Counting it made a
closed period's P&L read as break-even, and made the cash flow show zero
net income plus a fake "owner contribution" to Retained Earnings. The
as-of balance sheet keeps closing entries: after a close the earnings
belong in Retained Earnings, not current earnings.
Tests: tests/statements.rs, a two-month fixture with every expected number
computed by hand (Jan NI 1,700; Feb 880; balance sheets on four dates; a
closed January still reporting 1,700 and a cash flow with one financing
line). Mutation-checked: dropping the closing exclusion fails it (0 vs
1,700). Properties: period P&Ls partition a year at any split, and a
range's net income equals the change in current earnings across it, with
A = L + E on both dates.
