swaitsandClaude Opus 5.5 7741e96eb3 refactor!: one way to serve books: the stdio server is gone (D-44)
check / check (push) Canceled after 0s
The owner (2026-10-23): "We should probably just delete the stdio path
altogether. THere's no point in that. And it sitting there unused will
just lead to bitrot. Nuke it?"

Books are served only by the books server (`wanderbooks server`),
reached by agents through the bridge (`wanderbooks mcp --book ID`),
which stays.

Removed: `wanderbooks dev-stdio`, the `ledger-mcp` binary, and
`ledger_mcp::run` (stdio and `--http` over a bare data dir), with all
that only that mode had:
- files the books make coming back inline: `HandedFile.content_base64`
  is gone, and `download` and `expires_at` are always there;
- books with no access log or backups: `books.access_log`,
  `books.backup` and `books.back_up_now` are always offered, by scope;
- the settings file read and reloaded (`legacy_files`), the vault key
  named by a file or `--vault-key-file`, and the books dir's
  key-inside-the-books and git checks (with `paths.rs`);
- `wire.rs` (the bridge frames an agent's lines itself);
- `books.settings`' file fields and `books.start`'s `settings_source`.

`BooksServer` is built one way, from `Served` (a book as the books
server serves it), in production and in the unit tests. An unknown tool
is now a protocol error (mcp-tools.md). Inline file input is unchanged.

Then the owner's three decisions (2026-10-23, the question tool):
(a) `books.import_settings` is removed entirely (118 tools): old books
come in whole by `wanderbooks books adopt`, which reads their settings
file once; ledger-config keeps its settings-file parsing only as far as
adoption uses it (`load` and the path-reading `effective_receipt_policy`
are gone), and `books.chart_template` gives its settings as
`books.set_setting` changes. (b) The viewer's loose-books-folder mode is
removed (`--data-dir`, `--books-toml`, `--vault-key-file`, the settings
file and config.json followed): it opens only books of the data root,
reading settings from the journal and the vault from the book's own
`vault/` and `keys/`. (c) `wanderbooks dev-stdio` has no stub: it is an
unknown command like any other word. Also: an upload's expiry past the
calendar is an error, never an empty string.

Tests: every suite that drove the stdio server moved to
crates/ledger-cli/tests/ and drives a real `wanderbooks server` on a
data root of its own (tests/common), handed files by their download;
mcp_stdio.rs is mcp_journeys.rs. Tests of what is gone are deleted and
listed in docs/testing.md. Docs: plan D-44 (D-18 superseded), STATUS,
testing, rules, mcp-interface, the handbook, README; justfile recipes.

swaitsandClaude Opus 5.5 535874e0f3 fix(cash flow): a payment to a government is other operating, by its payee
The P3 cutover review's open point 2: a state's LLC filing fee, booked
to an organization-costs account (tax category organization_startup),
read as "Cash paid to suppliers and employees". B-14 rule 5 sent a
payment to class (g) only when every operating line's account was
taxes_licenses, so the account, not the payee, decided.

ASC 230-10-45-17, read in EY's guide that reproduces it (Statement of
cash flows, July 2026, p. 43; the PDF re-fetched and its SHA-256
recorded in docs/spec/sources/fasb-asc.md), lists apart "(b) Cash
payments to other suppliers and employees for other goods or services"
and "(c) Cash payments to governments for taxes, duties, fines, and
other fees or penalties". 45-25's classes name only income taxes (f)
among the latter, so the rest are (g), other operating cash payments.
A formation filing fee is rightly an organization cost (its account and
tax line), and still a payment to a government: the payee is what
45-17(c) is about.

So rule 5 now sends a payment's government part to (g): of an
operating payment the structure classes (d), what went to a party with
the government_agency or tax_agency role (the chain root's parties, so
a reversal keeps its original's class) is (g), on any account; and, as
before, a payment whose every operating line is on a taxes_licenses
account is (g). Every party a government: the whole payment. A
government and a supplier named together: the payment is split by their
resolved shares (B-35), the government's part (g), the rest (d), since
ASC 230-10-45-22 has "each separately identifiable source or each
separately identifiable use" classed "on the basis of the nature of the
underlying cash flows" (EY p. 44; quoted in fasb-asc.md; it names the
three activities, read for 45-25's classes too as a CONVENTION). The
government's part is the payment x its share / the whole, rounded half
to even to the base currency's places, the rest exact, so the line still
sums to the payment and a reversal mirrors it. Shares that don't
resolve leave the whole payment (d). One naming no party is decided by
its accounts. Receipts are untouched (a refund from a government stays
(c)). No total changes, only which operating row a payment is in.

Two limits, from the review of this change: a government selling goods
or services (postage) is 45-17(b)'s supplier "for other goods or
services", so the rule says, and the handbook tells the agent, to add
such a payee as a vendor, never with the government_agency role (the
books can't tell what a payment bought; the role says it). And payroll
keeps its structure (CONVENTION): an entry with a line on the salary
expense or a payroll payable control account, or on a pay tax category
(salaries_wages, officer_compensation, employee_benefits,
pension_profit_sharing), stays (d) whoever it names: withheld taxes
remitted are the employees' pay, and the payables mix them with the
employer's taxes, which a remittance can't tell apart. So a remittance
to the IRS is (d) as it was before this change; the employer's payroll
tax paid on its own expense account is a tax, (g).

The first company's books have this case: their state filing fee moves
from "Cash paid to suppliers and employees" to "Other operating cash
payments" at every date once its entry names the state's agency with the
government_agency role and its own entry is the one whose cash the
statement lists (paid from the bank, or on a card that is a lender's
credit, D-42, or by a member through the members' account while it is
a financing account, B-14 rule 11, the way that fee was paid);
charged to an operating-payable card, its cash leaves in the card
payment, whose payee is the bank, and it stays with suppliers.
STATUS says how to check both, and that the cutover goldens' cash-flow
snapshots will differ on the two class lines only (totals the same),
so the next cutover diff isn't read as a regression.

Docs: rules.md B-14 rule 5 (the rule, its source quoted, the date and
what it was before); fasb-asc.md (45-17(b) and (c) quoted exactly, with
the guide's SHA-256); the handbook's entries section (name the agency as
the party on a tax, fee, fine or penalty paid to a government; a shared
payment named with both amounts; a government selling services added as
a vendor; payroll remittances stay with pay; a fee on a card follows the
card payment); fasb-asc.md also quotes 45-22 and 45-22A; bookspec
example cash-flow.government-fees.toml (a filing fee and a lawyer on
one organization-costs account, a license on taxes and licenses with no
party, a penalty to a tax agency on the wrong account, paper from a
supplier, an annual report paid through a registered agent, 37.00 the
state's and 100.00 the agent's; every figure by hand) with a new `class.<a..g>`
key in the
cash_flow query (bookspec README; the runner checks every class the
statement has is given); testing.md; STATUS.

Tests: ledger-core tests/spec_cash_flow.rs
`a_payment_to_a_government_is_other_operating` (the filing fee and a
penalty to a tax agency (g); the same account paid to a lawyer, or with
no payee, (d); its reversal next month keeps (g); a refund (c)),
`a_government_payee_moves_a_fee_on_any_account` (a taxes_licenses
license with no party (g); a payment shared half and half between a
government and a printer split 50.00 (g) and 50.00 (d), the government
alone all (g)), `a_shared_government_payment_splits_to_the_cent` (a
third by percent of 100.01: 33.34 (g), 66.67 (d); amounts split as
given; the reversal mirrors to the cent),
`a_payroll_remittance_to_a_tax_agency_stays_pay` (withheld taxes
remitted from a payable holding its payroll role, and pay on a
salaries_wages account, stay (d) with the IRS named; the employer's tax
on its own expense account is (g)),
`a_government_selling_services_is_a_supplier` (postage to a vendor (d);
given government_agency, (g): the limit the handbook guards); src
cashflow.rs `tests` `a_government_part_rounds_half_to_even` and the
proptest `a_government_part_sums_and_mirrors`; the bookspec example;
from the P4 review, `a_reversal_takes_its_originals_payee` (a fee and
its reversal next month land in one class, the chain's payee deciding:
the books keep a chain's parties one, so reading the reversal's own
parties is an equivalent mutant) and
`a_shared_government_payment_a_member_paid_splits_both_ways` (a shared
payment a member paid: each part with its own on_behalf; fails with
the on-behalf part unsplit). docs/mcp-interface.md: books.cash_flow
and the Roles paragraph say a government or tax agency payee makes a
payment other operating, and a shared one two operating lines.
Broken to confirm: without the payee check the five spec tests and the
example fail; without the split for mixed payees the two shared-payment
tests and the example (class.d -549.50) fail; without the payroll
exclusion the payroll test fails; rounding toward zero fails both unit
tests; without the tax-category route
`operating_classes_follow_asc_230_10_45_25`, the second test and the
example fail. The viewer's cash flow page,
rendered on made-up books before and after: the fee moved from "Cash
paid to suppliers and employees" to "Other operating cash payments",
every total the same; and on made-up books with an annual report
shared between the state and an agent: each part on its own class
line, every total the same.

swaitsandClaude Opus 5.5 6c587086a0 feat(iif): carry each line's project in CLASS, the classes declared first
The P3 cutover review's open point 1: entries carry projects (classes,
B-37), but the QuickBooks Desktop file (B-34) left the CLASS field empty
on every line, and neither B-34 nor the README said so, though B-34 rule
6 says nothing changes silently.

Intuit's IIF Import Kit (vendored in docs/spec/sources/intuit-iif.md,
the kit's SHA-256 unchanged): the `!CLASS` header help says "Only the
NAME column is required" and a subclass's NAME is its parents' names
first, joined by colons; the kit's "Import First - List Declarations"
example declares `!CLASS` rows before any transaction, and its "2004
Deposit (Income)" example names the class line by line in CLASS. So the
file now declares every class in a `!CLASS` list after the accounts and
before `!TRNS`, and writes each line's class in CLASS (empty where the
line has none). Books with no class write no list, byte for byte as
before. A line whose class wasn't declared is refused
(IifError::UndeclaredClass), never written classless.

A class's NAME follows B-34's rules for an account's own name: plain
ASCII (rule 3), a colon written '-' (it would start a subclass),
trimmed, '?' if nothing is left, cut to 31 characters: Intuit's qbXML
Onscreen Reference gives `ClassAdd`'s Name "maxDT" : 31 (and 31 in the
Canadian, UK and Australian desktop editions; 100 only in Online), the
same as its `AccountAdd` Name (both JSON files vendored by SHA-256);
Conductor's QuickBooks Desktop API reference agrees and says the name is
case-insensitive. Classes whose NAMEs would match ignoring case get
" (id)", round after round, as accounts get " (code)", except that
among names that match, those already written differently from the
books (made safe, or tagged) yield first, a second " (id)" if need be:
a class's own name is kept unless another class's own name is the same
ignoring case (classes 1 "Café", 2 "Cafe", 3 "Cafe (1)" are written
"Cafe (1) (1)", "Cafe", "Cafe (1)"). Each class is tagged twice at most
and ids differ, so none is left alike (a hand-built list is refused). Each class name
written differently is an IifChange (IifField::ClassName), said one
line each in the warnings and in the package README, whose
"written differently" paragraph now names class names' limits; its IIF
line says CLASS is each line's project when there are classes. The MCP
and viewer notes count "account or class name(s)".

API: `iif_classes(ledger)` builds the list; `journal_to_iif` takes it
(`&[]` for none).

Docs: rules.md B-34 rule 8 with its sources; intuit-iif.md (the
`!CLASS` help, the list declarations and deposit examples, Intuit's SDK
department page, the qbXML Onscreen Reference's ClassAdd and AccountAdd
and Conductor's class reference, each with SHA-256);
mcp-interface.md (books.export iif, the package note); the bookspec
example iif-quickbooks-journal-file.toml (two projects: one carried and
renamed, one only declared; every line derived by hand); testing.md;
STATUS (open point 1 done; point 3 waits for the close, the owner said).

Tests: ledger-import
`iif_writes_each_lines_class_and_declares_the_classes_first`,
`iif_class_names_fit_quickbooks_and_every_change_is_listed`,
`iif_class_names_written_as_the_books_have_them_are_kept`,
`iif_refuses_an_undeclared_or_unfit_class`, property
`iif_class_names_never_clash`; ledger-package
`the_package_iif_carries_each_lines_project` and the bookspec example.
Broken to confirm: CLASS written empty fails the two exact-file tests,
the package test and the bookspec example; the " (id)" tag dropped fails
the names test and the property; tagging every name that meets (no
yielding) fails the kept-names test and the property (its shrunk case,
"A-B" beside "A\uFF1AB", kept in the regressions file).

swaitsandClaude Opus 5.5 528c070605 feat: invoices and bills take a project, line by line (B-37 item 8)
A client project's invoiced revenue and a contractor's billed cost could
never count toward the project: books.create_invoice and books.create_bill
posted at once with untagged lines, and only a draft's line takes a class.
Job costing (B-37 item 3) collects a job's billings and the supplier
invoices for its direct costs on its cost sheet, so each document line
now takes an optional project.

The owner decided it on 2026-10-22 (plan D-43, rules.md B-37 item 8):
each line takes one project or none; a document spanning N projects is N
lines, each with its own amount; no percentage split, so every figure is
exact; a cost truly shared among projects names none on the document
and reaches projects only as entries of their own under the company's
monthly allocation convention, when books.conventions has one (otherwise
it stays untagged and the agent asks the human). The reasoning, stated
in B-37: job costing charges a job the costs traceable to it, whole, and
reaches shared costs only by allocation on a stated basis. ASC
340-40-25-7 counts as directly related both the costs traceable to a
contract (25-7(a), (b), (d), (e)) and allocations of costs that relate
directly to it (25-7(c)); 25-8 expenses general and administrative cost.
The books carry the first whole on the document's line and the second as
the allocation convention's own entries; neither is a percentage on the
document (sources/fasb-asc.md, 25-7 and 25-8 added). The handbook's
projects rule and the line's class parameter say the same, and no
handbook sentence lets a shared cost be split across a document's lines.

The accounting: the document's entry posts one revenue (an invoice's) or
expense (a bill's) line per project its lines name, in the order each is
first named, each the sum of that project's lines, and the untagged
lines' sum as one more line (arap::document_parts, conservation checked
by a proptest). A document naming no project therefore posts exactly the
one line every document posted before. The receivable or payable line is
never tagged: it is a balance-sheet line, which item 3 counts nothing;
the payments (receive_payment, pay_bill) move cash against it and take no
project either. Nothing but the projects moves: the P&L, the 1099
worksheet (payments made, B-19) and party totals (what moved the money,
B-35) read the same with or without the tags (twin-books test); the
projects with the untagged lines still partition the P&L.

- ledger-core: DocumentLine.class_id (serde-omitted when none, so old
  documents serialize as before); create_invoice / create_bill split the
  revenue or expense side by project and tag it; an unknown project is
  refused whole (atomically).
- ledger-store: a document line's project is journaled as class_id on
  invoice.created / bill.created, and the entry's line as
  entry.line_class_set right after its entry.line_added (the entry.posted
  lines carry class_id, as a hand-built entry's do). Behind a NEW journal
  feature, document_line_projects (KNOWN_FEATURES, declared by new books,
  asked for before the first journaled line, not even the control
  accounts written on refusal); not `projects`, which the live books
  already declared: the owner consents again at the next upgrade. A
  malformed class_id is corrupt; null or absent is none. Untagged
  documents journal byte for byte as before; old journals replay
  unchanged.
- ledger-mcp: each line takes class (id or name, resolved like
  add_line's, every one before anything is written); the result gains
  notes for a finished or abandoned project, and on an invoice for an
  on-spec project (is there now an agreement? on spec a hoped-for
  payment is no receivable, B-37 item 4), tagged anyway; books lacking
  the feature refuse with format_upgrade_pending. books.get_entry shows a
  line's class_id and project. The handbook's "an invoice or bill takes no
  project yet" caveat now depends on the books: gone where the feature is
  declared, an "until their format upgrade" note where it isn't.
- ledger-gui: an invoice's or bill's page (its entry's) lists the
  document's lines, each project a link that opens it; the demo's client
  invoices are tagged to "Client work", whose snapshot is now its revenue
  less its contractors. Looking at the page in a narrow window found a
  tagged line's tag pushing the amounts past the pane (any tagged entry):
  the name is now cut to leave the tag room, the tag itself at most half
  the cell.
- bookspec: an `invoice` event, and `lines` with `project` on a bill or
  an invoice; example projects-invoice-and-bill-lines-count-by-project,
  worked by hand, both projects client work (Zeta 3,500.00 - 1,200.00 =
  2,300.00; Harbor 200.00;
  untagged -1,750.00; together the P&L's 750.00; Dana's 1099 payments
  1,250.00).
- fuzz: fuzz_store_replay can declare journal features.
- Tests: core, store, MCP, viewer, the P2-served cutover fixture and a
  viewer/server parity test (its month lists the same length, not
  empty); a tagged document's reversal nets its projects to zero, live
  and replayed; books.get_entry's class_id; the handbook served as a
  resource both ways; each fix broken to confirm its test fails
  (docs/testing.md). Docs: rules.md B-27 and B-37 items 3 and 8,
  sources/fasb-asc.md, plan/served.md D-43,
  mcp-interface.md, testing.md, parity.md, plan/STATUS.md.

No proof changed (no kernel arithmetic: document_parts sums with the
existing document_total).

The CPA package's general-journal.iif now holds every posted entry through
as_of (closing entries left out, D-36), written as plain ASCII with CR LF,
DOCNUM the entry id, QuickBooks Desktop's field limits and subaccount types
honoured, and every character written differently listed in the export's
warnings and the README (grouped by substitution, TINs masked). The 1099
worksheet stops at as_of too. PDFs print CJK, Arabic, Hebrew, Thai and
Devanagari (Noto fallbacks, OFL), and so does the viewer. has_full_tin reads
Unicode separators.

check / check (push) Canceled after 0s
Members' shares of earnings are split cumulatively by largest remainder in
the closes, the members' equity statement, the K-1 worksheet and the
viewer, so a member's capital on a given day never moves by a cent when its
month is later closed. Old closes replay as they were; the first P3 close
carries any true-up. Feature members_cumulative. Kani and Lean proofs of
the bounded drift; bookspec examples.

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.

swaitsandClaude Opus 5.5 57c4cc0ab6 config, mcp, gui: specs from sources, spec-blind suites, and the bugs they found
ledger-config: parse gets a sourced spec. A fiscal year starts on the
first of a month (IRS Pub. 538); tax_classification is read by whole
words (Treas. Reg. 301.7701-3, Schedule C instructions; "business corp"
no longer reads as an S corp, "corporation or S corporation" is refused);
duplicate or blank members and shared capital accounts are refused; a
negative or non-grammatical receipt threshold is refused; codes trimmed.
tests/spec_config.rs (65 spec-blind tests, 14 properties), fuzz target
fuzz_config_parse (weekly). Mutation: 55 of 55 viable caught (from 25/38).

The receipt policy moves to ledger-config, with one loader
(effective_receipt_policy) and one decimal grammar, so the server and
the viewer enforce and show the same rule (the viewer had its own: only
expense-like debits, a silent $25 default, and no config.json).

ledger-mcp: a module spec (MCP 2025-06-18 tools, JSON-RPC 2.0, the
operating contract). Amounts in are exactly -?digits[.digits]; a number
that is one account's code and another's id (vendors, classes alike) is
refused, not guessed; the threshold is validated at startup. Fixed:
add_line with a bad class journaled the line before refusing;
profit_and_loss_by_class ignored `class`; aging buckets said "0". A wire
in front of rmcp answers malformed JSON with -32700 and invalid requests
with -32600 and their id (rmcp dropped the first, omitted the id).
tests/spec_mcp.rs (26 spec-blind tests: every tool's result against its
own outputSchema, a random-call state machine checking the journal is
untouched by every refusal, amount grammar, previews, the receipt policy).

ledger-gui: money, accounting, and dollars never round (they rounded to
cents, banker's style); export file names avoid Windows device names,
trailing dots and spaces, empty names, and 255-byte overflow; specs on
attention, history, fuzzy search, and axis ticks.

ledger-core: the lifetime profit_and_loss is renamed unclosed_earnings
(docs/testing.md #3).

swaitsandClaude Opus 5.5 96c70f727a tax summary: Schedule K items stated separately; XLSX never shows a wrong amount
From the IRS form instructions (now quoted in docs/spec/sources/
irs-tax-lines.md):
- On Forms 1065 and 1120-S, Schedule K takes "only taxable portfolio
  interest", and charitable contributions are among the items the entity
  "must state separately". The tax summary counted both in ordinary
  income and deductions; they now go in TaxSummary::separately_stated,
  outside book_net and tax_net, and the report, MCP export, and viewer
  list them under "Separately stated to owners (Schedule K)".
- Schedule C: "Do not include charitable contributions". The category no
  longer applies to Schedule C (a sole proprietor's gift is personal, an
  owner draw).
- interest_income's note: interest earned in the business itself is
  ordinary income (other_income).

XLSX: a cell number is a binary double and Excel honors 15 significant
digits (Microsoft, "Excel specifications and limits"), so an amount over
$9,999,999,999,999.99 or finer than a cent is written as its exact text,
right-aligned, instead of a number Excel would show wrong. The old
conversion also fell back to 0.0 silently; gone. Property test: every
whole-cent amount up to 15 digits round-trips exactly.

swaitsandClaude Opus 5.5 d99589e6c1 import: grounded in Intuit's specs; atomic chart and bank imports
New vendored sources (docs/spec/sources/): Intuit's bank CSV upload and
IIF formats, ECMA-376 / Excel number storage, and the IRS form lines the
tax categories map to.

IIF export (rewritten to Intuit's IIF Import Kit):
- declares every account first (!ACCNT NAME, ACCNTTYPE, ACCNUM): an
  undeclared account is created in QuickBooks "as a new bank account";
  the MCP export types them (cash accounts BANK, the control accounts AR
  and AP, registered fixed assets FIXASSET, the rest by type);
- subaccounts by colon path, parents first; colons in a name replaced;
- ASCII only (IIF is ASCII text), dashes and quotes transliterated;
- the kit's 2007+ journal layout and M/D/YYYY dates; an entry using an
  undeclared account is refused.

Bank CSV:
- the 4-column layout is money out then money in by position, which
  matches Intuit's "Credit, Debit" and banks' "Debit, Credit" both (the
  doc's "Expense, Income" labels were wrong, the parsing was not);
- a slash date's order comes from the file (a part over 12 settles it)
  or the caller's new date_order, never a guess: Intuit recommends
  dd/mm/yyyy, US banks write mm/dd/yyyy;
- fractions of a cent and double negatives ("(-5)") are refused; the
  header is recognized on the first non-blank row.

Chart CSV: a blank code or name is refused with its row (found by the
new fuzz_import_csv target), and the core now refuses a blank account
code or name too (replay keeps older books).

MCP:
- books.import_chart_csv and books.import_bank_csv rehearse the whole
  file on a copy of the ledger first: a bad row anywhere refuses the
  file (before, a duplicate within the file, a parent after its child,
  or a date in a closed period left earlier rows behind);
- bank rules: the longest matching pattern wins (they arrive in a map,
  so "first match" changed from run to run).

swaitsandClaude Opus 5.5 bac81593e9 test(core): spec-blind suites and a live GnuCash oracle; four fixes they found
Max-testing pass, steps 2-4.

Spec-blind tests (rank 1-2): four agents, each given only the specs and
the public interface (doc comments and signatures, every body removed,
never src/ or the existing tests), wrote tests/spec_reports.rs (62),
spec_ledger.rs (72), spec_arap.rs (42), spec_assets_payroll.rs (50):
hand-computed examples per scenario and a proptest law per invariant
(conservation, partition, invariance, scaling, reversal cancels,
"a refusal leaves the books unchanged" over random invalid commands).
They found:

1. A refused payroll run changed the books: an all-zero run passed
   validation, then failed at post after creating seven payroll
   accounts and using up an entry id. validate_payroll_lines now
   refuses a run with no gross pay.
2. A refused add_account used up an account id (empty code, duplicate,
   unknown parent). The id is now taken only when the account is added.
3. Stale prose: close_period_to and members_equity still described the
   old last-member rounding.
4. Open (left #[ignore]d pending the owner): depreciation_schedule's doc
   says "through the month containing" the date; the code prorates that
   month by days.

GnuCash oracle (rank 3, an oracle never the spec): `just oracle` builds
GnuCash 5.10 in a container pinned by base digest and package versions
(oracle/gnucash/) and runs tests/oracle_gnucash.rs: 200 seeded random
books built through wanderbooks (entries, foreign lines, reversals,
monthly closes), every account's balance at month ends and random dates
and each month's P&L, compared exactly: 15,800 comparisons. First run:
4,724 differences, all from foreign lines; without them, zero.
Adjudicated from principles (rules.md B-3): wanderbooks booked
foreign * rate unrounded ($108.34567); a ledger in one money holds no
fractions of its smallest unit, and its cash must match a bank. The owner
decided: book in the base currency's minor unit, half away from zero.
add_line_fx now rounds; minor units per ISO 4217 list one (2026-09-17,
SIX), generated into Currency::minor_units and recorded in
docs/spec/sources/iso-4217.md. Replay now takes the journaled base
amount (replay_add_line_fx), so lines booked before replay exactly as
booked (contract: books_written_under_older_rules_still_open). Now:
zero differences, foreign lines included.

Tests: 449, from 223.

swaitsandClaude Opus 5.5 855d51e297 docs(spec): every rule traced to an authority; public-domain sources vendored
The owner asked that specs come from recognized documents, not from
anyone's memory. There is no single US bookkeeping bible; authority is
layered, and this records it:

- docs/spec/sources/: verbatim excerpts (whitespace normalized), each
  with URL, retrieval date, and the SHA-256 of the fetched file, of
  public-domain texts: Pacioli's 1494 treatise in Geijsbeek's 1914
  translation (double entry, the trial balance, one money, write only
  forward, correct by opposite entry, close into capital); IRS Pub. 583,
  538, 946, 15; the 1099-MISC/NEC instructions (2025 and 2026); 26 U.S.C.
  §6041, §6041A, §704; Treas. Reg. §1.263(a)-1(f) and -4(f); Notice
  2015-82; Rev. Proc. 98-25; Form 1065 instructions; 17 U.S.C. §105. The
  excerpts were extracted by matching each passage against the fetched
  file, so none can contain text the source doesn't.
- docs/spec/rules.md: the rule catalog, B-1 to B-22. Each rule says
  AUTHORITY, CONVENTION, or DECISION; cites its sources (FASB's
  Codification and Concepts Statement 8 and OpenStax quoted briefly,
  never copied: copyright and CC BY-NC-SA); and names the code that
  enforces it and the tests and proofs that check it.
- Spec blocks in the code now carry SOURCE: lines into the catalog;
  AGENTS.md makes sourcing rule 0 of the formal-methods bar.

Corrections the sources turned up: the de minimis limit is $500 in the
regulation and $2,500 by Notice 2015-82 (both now cited); 1099
thresholds after 2026 are inflation-indexed, so the engine's flat
$2,000 for 2027+ is an open question (B-19). Unverified ASC paragraphs
(360-10-35-4, 340-10, 230-10-45-10, 606-10-55-37B, 210) are listed in
docs/spec/README.md until someone with a FASB basic-view login reads
them.
