Each party's part of an entry is signed as its own account would show it, with a direction and its cash and in-kind amounts; a reversal is its original negated. Totals on a cash or all basis: for a member, all equals the members' equity statement and cash the K-1's cash. Money is cash, cards and the financing accounts, and a liability credit never pays its own creditor (creditor_of), so accruals and declared distributions count once. tin_last4 from the TIN or W-9 facts.

//! The bookspec examples (`bookspec/examples/*.toml`, P13, D-34), checked

//! place every example is loaded.
|
|
//!
|
|
//! Each example is a setup, events and expected values worked by hand from
|
|
//! its cited source (`bookspec/README.md` gives the shape). Every example
|
|
//! must load, whatever it asks or whichever appendix it is in: its shape,

|
//! its accounts, fixed assets, parties, members and payees, every event
|
|
//! (an entry, a reversal, a close or a bill, posting entry #N as event N,
|
|
//! with the parties and payee it is tagged with) and every change that
|
|
//! posts no entry (a rename, a policy). The queries the core answers

//! `party_totals`, `party_tin_last4`, `period`, `day`, `calendar_year`,

//! value, and the commands it tries
|
|
//! (`rename_account`, `add_account`, `set_tax_category`) accepted or
|
|
//! refused on a copy of the books, each after the event it names (`after`)
|
|
//! or the last; the formats appendix's (`iif_lines`, `iif_changes`) are
|
|
//! checked by ledger-package (`the_bookspec_iif_example_matches_the_engine`),
|
|
//! and a query no crate answers is refused. A key the shape doesn't have
