Attachments, statements, reconciliations, TIN vault, counterparty policy

MCP: books.link_attachment, unlink_attachment, attachments; link_to on
attach_receipt and file_document; record_statement, statements;
books.reconcile previews and, confirmed against a recorded statement,
records the reconciliation; void_reconciliation, reconciliations;
import_bank_csv links its source file; digest lists unreconciled
accounts.

TIN vault: books.set_w9 takes the TIN and the form into the encrypted
vault (last four in the books); books.vendor_1099 include_tins and
save_csv_to for the CPA's copy; books.get_w9; books.purge_tin. A leak
test scans every tool output, the journal, the database, and the blobs.

[books] parties = off | suggest | require (default suggest): every
preview names the entry's party or suggests likely ones; require refuses
to post until it names one or is marked as having none (entry.no_party).

Viewer: documents on every subject page; statements and reconciliation
history per account; reconciliation pages; reconcile and
no-counterparty attention items; party money by period (paid out,
received in, net, what for, by month); Needs attention gets its own
full-width section.
