books.start passed Integrity::default() to the attention engine, so it
asserted "database matches, no file failures". On a book whose database
differs from the journal, or whose stored file is missing or corrupt, the
viewer showed the database/stored-files items and the server did not: the
two lists diverged exactly where they matter most.
Call find, which computes the check: every distinct stored blob is read
and hash-checked once (a damaged blob is still reported per attachment
filed from it), and Store::disk_check now makes the viewer's comparison
through a snapshot of its data directory instead of reporting a match.
The parity test now damages its own fixture (removes the receipt's blob,
then changes a projected account row) and asserts both lists still agree
item for item and both name the damage. On the demo books (138
attachments, 138 distinct blobs, debug build) books.start takes about
0.26 s warm, 0.29 s cold, so the real check costs no decision.
Needs attention was computed by the viewer alone, while books.start
hand-picked a handful of next steps. The human's list and the agent's
could disagree, and a new item had to be written twice (or, as
books.start showed, not at all).
Move the engine to ledger-package over PackageBooks: one function,
find/find_with(books, today, settings, integrity), reads the ledger, the
journal's event types (an entry's origin), the attachments and their
links, the statements, the reconciliations, and the database check. The
viewer's attention module now only maps Target to Route; books.start
turns the same items into its next steps (why = the item's title, top 12),
so the list the human sees and the steps the agent gets cannot drift.
PackageBooks gains settings, journal, statements, reconciliations and
disk_check, implemented for Store and Snapshot, so both views answer
alike. The W-9, reconciliation and 1099 predicates move beside the items
to keep one copy. ledger-package gains ledger-config and serde_json (the
receipt policy and the tool arguments the items carry).
Tests: view_model.rs and spec_kept.rs pass unchanged; the new
attention_parity.rs compares the viewer and books.start item for item on
the demo books and on a book written entry by entry. just check green.
The 8.0.6 checklist for this slice, which adds fields on party.updated
(an email and two default terms) and the invoicing settings it guards:
1. books_written_under_older_rules_still_open now hand-writes a party's
email and terms and an invoicing setting through JournalWriter, and the
books still open, verify and replay them.
2. A new old-books fixture, p4_s42_settings_parties, was written by the
version before this slice (1bfce915, through the old-books-writer
harness) with a party, a vendor, two posted entries and three settings,
and its expected.json from that version's code. This version opens it,
verifies it and reports its figures identically.
3. books_p2_served_cut_over_whole gains a refused invoicing setting before
the go-ahead; the same call succeeds after it.
4. documents_v2_is_its_own_feature: books that declared every earlier
feature stop at its declaration as newer, wait for the upgrade, and
name exactly it in the upgrade.
No figure moves (item 5): settings and party facts enter no report.
Merge does not need the owner's go-ahead; the live books refuse the new
party and setting writes with the upgrade remedy until he gives it.
ledger-import invoice_pdf (templates/invoice.typ): seller, bill-to,
number, dates, terms, lines, total, each settled line and the balance
due; money formatted in Rust (the template does no arithmetic), text as
data, deterministic bytes. Stamps as a rubber stamp would mark it, in
red: PAID (with the day it was paid in full: the invoice is then the
customer's receipt), PARTIALLY PAID, PAST DUE, VOID; DRAFT in gray for
S4's preview. ledger-package invoice_document builds it from the books
as of a day: the derived figures (B-38), each payment that stands on its
own line with its date, payment method and reference; re-created copies
say so (the issued copy is kept from S4 on and never changes).
books.document pdf hands it over as a download; the viewer's invoice
page saves or opens it. The owner asked for the paid stamp with the
payment's date and details (2026-10-24).

books.document shows one (ref invoice:N or bill:N) as of a day: lines

books.void_document voids an invoice or bill that should never have

payment stands on it, naming that payment). books.control_check ties
receivables and payables to their documents (B-23, B-38 INVARIANT 1):
balance, documents' total, lines that are no document's, the documents
needing attention; books.verify checks the identity and books.digest
lists its problems (control_problems). books.receive_payment and
books.pay_bill take instrument (tagged in the same call) and reference
(in the description), and answer the document's derived remaining and
status. The books record payments; they never collect or make them
(D-45). Docs, handbook and STATUS; the over-the-wire test

tool is refused before it runs as an unknown argument pointing to
books.begin_upload (access log: refused inline_file).
Out: books.export (every format), books.asset_labels and
books.get_receipt view bytes hand the file over (HandedFile: download

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.

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).

cost unrecovered if repaid. To date or this fiscal year. By month,
revenue and costs with the net to date in its own strip; costs by

On the live books a reconnected bridge got no token from a keyring that
couldn't be read, was told to "make a token", and after
`token create --replace` kept on with the new token in memory while
`download` read a revoked one from the keyring.
- tokens.rs INVARIANT 4: keeping a token removes every item for its
account in every collection, makes one and reads it back; reading finds
every item and, finding several, refuses with how to keep one again; a
locked or unreachable keyring is KeyringError::Unavailable, never
"no token". The logic is shared by the OS keyring and the test files
(now a folder per collection a test can lock, make unreachable, or
plant a second item in).
- make_token reads the token back before saying anything, or revokes it.
- The bridge tells the agent the keyring is locked or unreachable and the
token is fine (or that it holds several items), never to make a token;
it reads the keyring again before every new session, even with a token
held.
- `wanderbooks token check --book ID [--name N]`: whether the token kept
here is the books' live one, asked by its SHA-256 (admin op
token_check), never its text.

`wanderbooks books put-aside ID DATA-DIR [--vault DIR --vault-key FILE]

TIN vault and its key, their settings file, the git history around them,
old exports) whole into numbered folders of their own in the root's
legacy/, a list of where each came from written and synced first. Nothing
is deleted. Refused unless the books hold everything the old copy does,
byte for byte (journal, stored files, vault records, key; what adoption
left behind and records the books sealed anew are listed and go aside
too); while a wanderbooks process holds it open for writing; when its
head moved since the preview; for links, paths named twice, inside the
root or missing, a vault or key given as a plain path, and paths on
another disk. Renames never replace anything, and a move cut short puts
back what it moved. Three review rounds of data safety.
The plan records the cutover's answers (Q-3: move the old copies aside;
the backup repository and folder).
Also: `connect`'s "the books fernhill' agent token" reads properly, and
the restart tests wait for a copied program to be runnable (a child forked

Mutation testing pauses until P12 (D-33, owner 2026-10-20), which reruns
the whole max-testing pass over everything since P1. Before the pause,
pass 1 on slices 3-6 and its triage gave tests in ledger-store,
ledger-package and ledger-mcp, and three real bugs, fixed:
- the command line took an admin answer longer than four MiB, or cut off
before its newline, whenever the bytes that came still parsed;
- The CPA package put a twin's number on the last dot of the whole path,
so in a folder with a dot the second file landed in another folder;
- a document or category named of dots alone ("..") could climb out of
its folder when the CPA package is unpacked.
The plan gains P13, bookspec (D-34): a formal, sourced accounting
specification first (rules with symbolic forms and worked examples), then
its own formal validation and a conformance harness any engine can be
tested against, seeded by P3's regression tests. docs/testing.md records
slices 3-8 and what P12 must cover; plan/STATUS.md says where P2 stands.

environment (--root, else the root setup recorded in a file only this

user could swap is refused; no error names it. Setup keeps a recorded
root, never makes a second root or moves books while one holds any, and
leaves a folder holding other things untouched. Books are created and
adopted one at a time; adoption reads the source under its writer lock
(changing nothing in it), copies into staging, re-hashes every stored
file against its name, checks every named file is there, opens and
verifies the copy with the source's head, imports settings for books
that keep none, syncs, and only then renames it into place.

Exit(code) instead of ending the process; ledger-mcp and ledger-gui are
one-line shims (the live books keep using them until the cutover).
wanderbooks dispatches dev-stdio and gui to them in-process; a mode must
come first and owns its flags. The gui feature (default) leaves the
viewer out of the server-only build, which just server-only builds,
clippies, tests, and checks for window libraries. The viewer's mutation
recipe is retired (owner, 2026-10-18); its two musts are tested
directly. Two review rounds; mutation on the diff (docs/testing.md).

Settings, conventions (posting templates, approval rules, policies,
close steps, calendar, mappings, notes), decisions, open items and
entry approvals are journal events (journal format 2). Books that keep
their settings never read wanderbooks.toml or config.json; the server
and the viewer take the vault key from --vault-key-file instead.
books.import_settings moves a settings file in once, exactly as the
server reads it. Approval rules, when enforced, gate every posting
path. Replay refuses what it can't read as newer, never as corrupt.
Lean: a record changes no figure. Mutation on the whole diff: every
survivor killed by a test but two equivalent (docs/testing.md). The
Company page says a late open item is overdue in words, not colour
alone.

mise.toml: pin cargo-mutants 27.1.0 and cargo-fuzz 0.13.2 (the latest
published, and what is installed) instead of "latest", so mutation and
fuzz runs repeat (plan/served.md I-13, P0).
docs/mcp-interface.md: the spec had two Transports sections, and the
first claimed bearer-token auth on Streamable HTTP. There is none: the
server uses rmcp's default config, whose only guard is a Host check for
localhost, 127.0.0.1 and ::1, with no token and no Origin check. One
section now says so plainly and points to plan/served.md P2 for auth.
ledger-cli AGENTS.md template: "the journal is the evidence - read it,
don't guess" led an agent to cat the journal file instead of asking the
books. The template now says to trace a figure through books.get_entry,
books.search_entries, or books.export (journal or general_ledger), and a
new bullet says the books are reached only through the wanderbooks MCP
tools: never open, list or parse the books' files, not even to look; if
a tool can't answer, say so. The other lines that sent the agent to the
data dir go too: onboarding is triggered by an empty books.chart instead
of a missing journal.jsonl, the CPA paragraph drops the ledger-gui
--data-dir books-data command, and the backup note no longer names the
journal's path. Test agents_md_reaches_the_books_only_through_tools
pins this; agents_md_carries_the_contract no longer expects journal.jsonl.

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.

- core: ControlAccount keys, Ledger::assign_role/check_assign_role/role_account (rules.md B-23): one account per role, of the role's type, balance sheet roles move only when empty; invoices, bills, payroll, remittance, and closes post to the assigned account; an assigned role frees its default code for renumbering
- store: role.assigned journaled and replayed (strict account_id)
- mcp: settings.rs reloads by content at the start of each request, keeps the last good settings on a broken edit; books.settings with chart problems; digest settings_problems; instructions say when to edit the toml
- viewer: journal text for role.assigned
- cli: full example wanderbooks.toml, tested to load with every example uncommented
- tests: spec_roles.rs (25, spec-blind), store roles.rs (6), MCP reload/problems/roles, settings unit tests

New books dirs get .codex/hooks.json beside .claude/settings.json; both
SessionStart hooks run one justfile recipe, which reports the viewer's
state per [viewer] open_at_start (and opens it itself for "always").
Codex runs project hooks only once the dir is trusted and the hook
approved, so new --codex says so; AGENTS.md stays the fallback.

The viewer offer (open_at_start) lived only in AGENTS.md, so it depended
on the agent remembering it on its first turn. The scaffold's
.claude/settings.json now runs just gui-status at session start and hands
the agent the result plus open_at_start.

The scaffolded justfile now detaches the viewer (log in books-data/gui.log)
and won't open a second one for the same books. AGENTS.md tells the agent
to check gui-status at session start and follow open_at_start
(ask/always/never) in wanderbooks.toml.

wanderbooks new --codex registers the books' MCP server with Codex (as
wanderbooks-<dir>) and starts Codex; the scaffolded justfile gains codex
and codex-setup. The site drops 'hire', says free up front, shows
Claude Code or Codex + wanderbooks = a complete bookkeeping system, and
explains MCP and cost in the FAQ.

wanderbooks new DIR installs the server and GUI if missing, writes the
books dir (AGENTS.md + CLAUDE.md, wanderbooks.toml, justfile, .mcp.json,
.claude/settings.json approving the server), commits, and starts claude
onboarding. install.sh: Rust + cargo install + wanderbooks new in one
line. The tax summary labels its net when accounts are uncategorized.
