Parties: one directory for vendors, contractors, customers, employees,
members, platforms, agencies, banks, landlords (ledger-core parties.rs).
W-9/W-4 facts without the number (last four only; any nine-digit run in a
party field is refused, Treas. Reg. 301.6109-4). Vendor and customer
records link to parties on replay; core tags every bill, invoice, payment,
and reversal with its counterparty. Journal events party.*,
entry.party_set; payroll lines name the employee party.
MCP: books.add_party, update_party, set_party_roles, set_w9, set_w4,
parties, party, set_entry_party; draft_entry party; run_payroll employee;
show party. Viewer: Parties directory and party pages, search, journal
text, W-9 attention, demo data.
One definition of a party's money (ledger_core::parties::activity) for
MCP and viewer. 1099 amounts count payments from cash and financing
accounts (a member paying for the company counts; a card doesn't; a
prepayment counts when made): vendor_1099_report_with, B-19.
Store: attachment links to any subject, statements, reconciliations
(schema v11), with replay and projection. ledger-vault: encrypted TIN and
W-9 records (ChaCha20-Poly1305, key file outside the books).
Spec-blind tests for parties (core, store, MCP, viewer) and attachments.

A payroll tax remittance was journaled as a plain entry, so the viewer
labeled it "Journal entry" and, at a 0.00 threshold, flagged it as
missing a receipt (the server posts it without one, like a payroll
run). The store now names it with payroll.taxes_remitted, as it names
runs with payroll.run; replay and the projection pass over it, and the
viewer's journal page describes it.
tests/view_model.rs: the cash history is never empty when cash moved
and ends on the last day it did; the prior month runs to the same day;
burn averages over only the months the books cover, half away from
zero; cash accounts found by name when the settings name none; card
accounts; each entry's accounts debits first, once each; only what
arrived since the last refresh is fresh; integrity counts files again
without rereading them; the invoice's customer, the bill payment's
vendor, payroll and remittance origins.

Kpis gets a spec (cash, liabilities, receivables, month-to-date against
the same days of last month, fiscal year to date, burn). tests/view_model.rs
computes each from ledger-core on random books (month ends, leap days,
any fiscal start) along with the period ranges, cash history, account
labels, journal count, receipt rule, origins and parties, the blob
root, and integrity counts. Burn rounds half away from zero, like the
rest of wanderbooks (it was banker's rounding).
