swaitsandClaude Fable 5.1 df93d8b951 feat(viewer): the invoice page shows its number, terms, bill-to and PO (P4b S4.5)
The viewer reads the same invoice the server prints. The Money in list and
the page title name an invoice by its issued number (a legacy invoice keeps
"Invoice {id}"); a Details card shows the number, terms, the bill-to as it
was at issue (contact, address, phone, email), Ship-to, the customer's PO
and memo, and a bill's vendor number, day received, terms and memo. Save
invoice PDF still re-creates the current copy; when the issued copy is
filed (found through its link to the invoice, never by name) Save issued
copy and Open issued copy hand over those very bytes, checked against
their SHA-256. Nothing is written to the books.

swaitsandClaude Fable 5.1 bfd453b679 test: the tests P6's gate never reached, under one-record dedup
check / check (push) Canceled after 0s
two-user / two-user (push) Canceled after 0s
P6's branch paused with its gate interrupted, so five tests that
predate plan P6 step 4 (the same bytes filed twice are one attachment,
linked to each subject) still encoded the invariant it replaced, and
one golden carried counts from before extraction records existed.

- store: `blob_dedup_and_hash_verification` expects one attachment
  row under the first filing's name, not two. The `attach_receipt`
  spec block's INVARIANT 2/3 now say what P6 built; the stale "each
  filing is its own attachment" was the one wording left.
- store: the power-loss replay copies the blob store too. The books
  on disk were always journal, database and blobs; verify now reads
  an extraction's text blob (P6 step 2), so a copy without `blobs/`
  cannot verify.
- store: the refusals property allows `AttachReceipt` and
  `FileDocument` to journal nothing when the bytes are already on
  file: the record they return is the record they were.
- viewer: each statement the reconciliation helper files has its own
  bytes (a wrong statement is voided and a new one comes); identical
  bytes would be one record, and a record is one statement.
- viewer: the tall sidebar's shapes golden is re-blessed. The fixture
  books now carry extraction records, so the Overview attention
  count, the event count and the verified-file count the sidebar
  prints moved; no layout changed.

swaitsandClaude Fable 5.1 335a3eaa7e merge: P4b S7, bad debts (branch S7, 4b4fecb9)
The fourth of the paused branches: Ledger::write_off and the bad_debts
control role, invoice.written_off with its evidence filed in the same
store call, books.write_off_invoice, the write-off on the timeline and
in Needs attention, Lean writeOff_within_bounds, rules.md B-41 and the
bookspec examples. Twenty-eight files conflicted with the S4.4, S5 and
S6 merges; resolved as plan 8.0.2 says, keeping both sides' appends with
their seams restored, and: the scope table at 125; S7's law numbered 37;
B-41 placed before B-42; the handbook's step 4 and recovery procedures
folded into the one invoices-and-bills section; S7's wire tests in their
own module with the confirm S4.4's contract needs; S7's copy of the
payment steps dropped (S6 replaced them with Ledger::settle) and its
write-off journaled through S6's journal_auto_lines; in the old-books
fixture S7's hand-written write-off moved to a second invoice, since
S6's hand-written payment settles invoice 1 in full.

swaitsandClaude Fable 5.1 be58059830 merge: P4b S6, paying on terms (branch S6, 6c4480cd)
The third of the paused branches: Ledger::settle with discounts and the
processor's fee (kernel::settle, Kani settle_is_exact, Lean
settle_posts_a_document_step), books.receive_payment and books.pay_bill
with applications, books.bills_due, the agings' detail and tie-out, the
aging exports and the CPA package's aging CSVs, the handlers in
tools/settlements.rs. Twelve files conflicted with the S4.4 and S5
merges, resolved as plan 8.0.2 says: both routers; both test appends
(the shared match arm in arap_standing.rs spliced into both tests; the
shared `.unwrap()` in store.rs); the scope table at 124; one
invoices-and-bills handbook (S5's send step 1 with S6's steps 2, 3, 5
and procedures) registered once; docs/mcp-interface.md with S4.4's
create docs and S6's payment docs; S5's law renumbered 35 and S6's 36
(S1's is 34); the parity rows and sections of both. S6's wire tests
create their bills as S4.4's contract now requires (confirmed, the
vendor's number, a line account, the vendor's invoice uploaded) and live
in their own module beside S4.4's tests.

swaits 485bd4ae5f feat(attention): unsent and unreminded invoices (P4b S5)
The books record that an invoice went out but do not chase it. U0b's
one attention engine now lists two items the sent record makes possible,
in the viewer's Needs attention and in books.start's next steps alike:

- "Invoice INV-0007 was never sent": an issued invoice (a number) still
  Open or Partial, with no send recorded, once today is past its issue
  date plus invoicing.unsent_days (default 2). A legacy invoice with no
  number is exempt, and so is a void or settled one.
- "Invoice INV-0007 is overdue: remind the customer": the invoice is
  overdue and its last send is older than invoicing.reminder_days
  (default 14). An invoice never sent gets the first item, not this one.

Both are Todo, open the invoice, and offer books.mark_sent with its
invoice and the tool's defaults. The viewer maps the new
Target::Invoice to its invoice page (one line; items still come only
from ledger-package), and the two lists cannot drift.

Tests: an_unsent_invoice_is_listed_until_a_send_clears_it (the overview
draws it; attention-unsent-invoice.png; a send clears it),
a_legacy_invoice_with_no_number_is_never_listed_as_unsent,
an_overdue_invoice_with_an_old_send_is_asked_to_remind, and
an_unsent_invoice_is_on_both_lists (viewer and books.start, step
books.mark_sent on invoice:1). The existing attention parity test stays
green.

swaits 6c4480cdc8 feat(package): aging CSVs in the export and the CPA package (P4b S6)
The CPA's first tie-out is that the aging equals the control account, so
books.export and the CPA package now write ar_aging.csv and ap_aging.csv
from one builder: one row per open document (number, party, dates, terms,
total, paid, discounted, outstanding, bucket, days overdue) and a TOTAL
line carrying the outstanding sum, the GL account and balance, and the
difference (always 0.00; B-23, B-38 INVARIANT 1). XLSX and PDF lay the
same aging out as a statement with the tie-out beneath it.

The package README states the tie-out, the gross discount method (A-8)
and the direct write-off method (A-5). The chart templates gain 6995
Purchase Discounts so no template puts another account at a control
role's code (4100 and 6060 already match). The viewer's Money out list
gains the discount-deadline column and colours a due-soon or
discount-open date; the screenshot is re-rendered.

Test: the_aging_csvs_tie_to_the_control_check in ledger-package; the
existing package file-order test and mcp_journeys see the two new files.

swaits 22cdfcf34b refactor(arap): rustfmt the unit's files, and the write-off's SOURCE line (P4b S7)
No behaviour: the files as rustfmt leaves them after the unit's edits
(the commits before this one were made before the formatter ran), and the
Ledger::write_off spec block cites A-5 alone for the direct write-off
method (A-6 is the hand-entry refusal, not this command).

swaits b731d7ed04 feat(arap): a write-off on the timeline, and the CPA's note (P4b S7)
The viewer's invoice page already drew a WriteOff movement; now the
fixture proves it: a written-off invoice reads Written off, owes nothing,
and its timeline's "Written off" row opens the entry (the screenshot
invoice-written-off).

Needs attention gains the one item the tax rule asks for: a write-off
made this calendar year is listed, one per invoice, as "Write-off
awaiting the CPA's note", with what was written off, the day, and the
prompt that opens the document. Whether a debt is worthless, and in
which year, is a tax judgment that stays with the CPA (plan 8.3.16); the
books flag it and keep the evidence beside it until the year ends. The
item is computed in ledger-package's one attention function, so the
viewer and books.start see it alike; view_model.rs compares the two reads
on the same books.

The handbook's invoices-and-bills section starts here (S4.5 adds the
issue, terms and payment steps around it): step 4 says when to void, to
write off, or to reverse, and the recovery procedures D-49 records — the
same year, reverse the write-off and record the payment; a later year, a
plain entry to a bad-debt-recoveries revenue account, the invoice staying
written off (IRC §111).

Tests: a_write_off_shows_on_the_timeline,
a_write_off_is_flagged_for_the_cpa.

swaits 13282cf80e feat(arap): terms, numbers and line accounts in the core (P4b S4.1)
Documents could name only one revenue or general-expenses account per
project, had no number of their own, and took a due date the caller had
to work out. This slice gives the core the pieces the rest of S4 needs,
and journals nothing: an old-shape document still writes byte for byte,
so the owner's books need no upgrade for it.

- Payment terms (B-39): Net n, Net n EOM, due on receipt and a custom
  date, with the early-payment discount and its exact bound
  (kernel::discount_max, Kani + bridge). A due date past the calendar's
  end is refused, never a panic, and a discount is refused with terms
  that have no net days.
- Invoice numbers (B-40, A-2): first_number plus the count of numbered
  invoices, zero-padded to four digits and wider past 9,999, stored at
  issue, kept by a void; legacy invoices are uncounted.
- Line accounts (A-10): a document line may name its account, and the
  entry posts one line per (account, project) part. An invoice line takes
  revenue or a liability holding no role (deferred revenue); a bill line
  an expense or a non-cash asset holding no role. Roles, cash accounts
  and headers are refused.
- A line's amount is exactly its quantity times its unit price
  (kernel::line_amount, Kani + bridge): both or neither, never rounded.
- A vendor's invoice number names one standing bill per vendor, with
  case, spaces and hyphens ignored, unless a duplicate reason says why
  (B-40).
- The record fields S4.3 will journal: number, terms, bill-to and seller
  snapshots, customer reference, memo, the empty sends list S5 fills, and
  the bill's received_on, all optional and defaulted.

The store refuses a line carrying an account, quantity or unit price
before it rehearses or journals anything: those fields are journaled from
S4.3's documents_v2 on, and I-3 will not let a public write replay
without them. `document_line_fields_wait_for_documents_v2` proves the
refusal, the unchanged journal and allocators, and that an ordinary line
journals exactly as before. S4.3 removes this guard in the same change
that journals the fields and adds its byte-for-byte test.

The document commands keep their signatures; create_invoice_with and
create_bill_with take the optional fields for S4.3 and for tests. They
are the existing issue commands with more fields, not a new state
transition, so no Lean Step is added. Kani: line_amount_is_exact runs in
`just prove`; discount_max_is_bounded relates a product to a quotient and
runs in `prove-slow` (163 s), as the proration charge harnesses do.

just check green; just prove green.

swaitsandClaude Opus 5.5 c1f9001cfe feat: the invoice PDF, with stamps and each payment (P4b S3)
check / check (push) Canceled after 0s
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).

swaitsandClaude Opus 5.5 b7b7f17163 feat(viewer): Invoices & Bills, a document's page, overview tiles (P4b S2)
check / check (push) Canceled after 0s
One sidebar item, Invoices & Bills (the owner's choice, 2026-10-24),
with Money in (invoices) and Money out (bills) tabs: what is owed and
overdue, and the list tied to its receivables or payables account
(Agrees, or what to look at); filters Open, Overdue, Paid, Void, All;
rows by due date, an overdue one saying how many days late, each named
in full for assistive tech. A document's page: total, received or paid,
still owed, status; its lines with their projects; its timeline, a
payment later reversed marked so, each row opening its entry. The
overview adds Owed to you and You owe on bills once the books have
documents. Every figure is the document's derived state (rules.md B-38).
The sidebar's rows (and the rail's) give way to 22 points, not 24, so
13 links still fit the owner's 1479x519 window unscrolled; the
sidebar's tests compute heights from the link count; the 1440x920
golden is re-blessed for the new link.

swaitsandClaude Opus 5.5 d7fa16e974 feat(arap)!: documents read their figures from standing lines; control accounts
check / check (push) Canceled after 0s
refuse hand entries (P4b S1, part A)

Plan P4b (D-45), slice S1, the engine half: rules.md B-38.

- ledger-core: every receivables or payables line carries its document
  (Ledger.line_docs: DocRef, Movement, DocTag), written by the document
  commands in the step that posts it, derived on replay from the existing
  document events (the role's account as it stood then; payments by the
  ordinal rule), copied onto a reversal's mirror. Ledger::stands_on;
  doc_state / invoice_state / bill_state (total, paid, outstanding,
  status Open/Partial/Paid/WrittenOff/Void, overdue days) as of any day;
  ar_aging / ap_aging read them, so reversed payments and voids are right.
  The control guard (add_line, add_line_fx, post_entry,
  register_recurring) refuses untagged lines on receivables/payables,
  exempting a reversal's mirror of a legacy line; replay never refuses.
  Bounds (kernel::running_bounds, bounds_kept) on payments and reversals;
  a document reversal never dated before its entry; deposit/payer accounts
  must be cash-like and hold no role. New API: receive_payment_with /
  pay_bill_with (PaymentDetails: instrument, reference), void_document /
  check_void_document, control_check, payments_recorded,
  standing_payments, replay_reverse_entry. Invoice.amount_paid/status
  remain only as derived caches for the MCP layer until part B.
  cashflow bill_splits reads payments from the tags.
- ledger-store: journal feature document_standing (D-39 gated) for a
  payment accepted only because an earlier one was reversed;
  receive_payment_with / pay_bill_with (instrument journaled as
  entry.instrument_set, reference in the description), void_document;
  replay uses replay_reverse_entry; schema 15 drops the projection's
  amount_paid/status. Fixture p4-arap-before + golden figures written by
  the version before S1, adjudicated in arap_standing.rs.
- ledger-gui: party card, cash "coming up" and company owed totals read
  doc_state as of today (late from the derived state).
- Lean Documents.lean (control_agrees and friends); Kani
  bounds_check_matches_definition,
bounds_kept_is_the_definition_on_books_in_bounds;
  rules B-38, B-18/B-23 amended; bookspec `older = true` for legacy hand
  lines; tests that hand-post to 1200/2000 post as replay or renumbered.

Review fixes (both reviews of part A):
- control_role_of guards only an account the role is assigned to or one
  holding its documents' lines (a chart's own 1200 Equipment or card at
  2000 is free until a document posts there); payment accounts check
  other roles by holds_role (type-checked). The MCP tests that failed on
  the guard (oracle_mcp, spec_projects) pass unchanged.
- standing_payments leaves out reversals (sorted, deduped); replayed
  tags match the movement's side; payments_recorded counts every payment
  event (tagged or not, Ledger.payment_events) and refuses overflow.
- The record caches settled (paid + discounted + written off) and owed
  (Invoice/Bill.owed, never serialized): a void never reads as paid.
- assign_role: receivables/payables refuse moving onto an account with
  untagged lines (RoleAccountHasHandLines) and, on their control account
  holding a balance, say DocumentRoleHoldsBalance (no hand entry named);
  B-23 reworded. The reversal-mirror exemption only takes a hand line
  off (even chain depth); putting it back is refused.
- DocStatus Overpaid and Unattached; aging leaves out credit balances;
  ControlCheck.attention lists out-of-bounds and unattached documents.
- stands_on counts a chain in order; indexes (doc_index, doc_accounts,
  order_pos, reversed_by) keep the derived figures linear.
- Viewer reads a post-dated document as of its own date; one state per
  row. bounds_kept's side-crossing documented as intended.
- Tests: ten new spec_documents scenarios, stronger proptests, store
  proptest arap_props (live = replay = snapshot at every date, closed
  months), fuzz ops void/payments with details, a GUI post-dated test;
  Lean Step.assign / Step.release with unattached_zero kept; model
  limits stated in docs/testing.md and B-38.
Review fixes (CPA and engineering lenses): only an assigned role's
account or one holding document lines is a control account (a chart's
own 1200 asset stays free); a role can't move onto untagged lines or off
document lines (Lean Step.assign); a void's cache never reads as paid;
no Decimal sum panics; per-document indexes keep figures linear; a
replayed tag matches its side; the feature gate counts payment events;
a payment's reversal is never listed as standing; an overpaid document
has its own status; the viewer keeps post-dated documents.

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 a9de57d6cd feat(viewer): thumbnails drawn at load, kept on disk by hash; no picture crashes it
check / check (push) Canceled after 0s
Tiles draw a thumbnail, not the file: the top of the first page, 560
pixels wide (never scaled up) and at most 420 tall, rendered by two
workers of their own so opening a file never waits behind them. Every
file's thumbnail starts when the books load, before the documents page
is opened, and the live viewer keeps each as <sha>.png in
$XDG_CACHE_HOME (else ~/.cache)/wanderbooks/thumbs/v1-560 (private to
the user, written whole and renamed into place), so the next launch
reads small PNGs, not PDFs. A file's name is its content's hash, so a
thumbnail always matches the file the books hold; the blob is still read
through the verifying store each time, so a corrupt or missing file is
an error, never a kept picture.

From review: a picture or page past the device's largest texture is
scaled to fit (egui panicked on it, in the full view too); a renderer
panic is that file's error, not the end of its worker; a thumbnail asked
for before the cache moved is dropped, never shown over a newer one;
text thumbnails keep 2 KiB.

A text/markdown file (or text/x-markdown) is drawn as formatted text by
egui_commonmark, with no image loading, so a document never makes the
viewer read a file or the network; any other text/* type as its
selectable text. UTF-8 only (a leading byte-order mark dropped), at most
2 MiB; past that or not UTF-8, the viewer says why. The documents page's
tile shows the text's first lines. The SHA-256 row is cut to its column
(it ran off the panel and widened the page under it).

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).

swaitsandClaude Opus 5.5 641184d3a3 viewer: the sidebar's links fit short windows
check / check (push) Canceled after 0s
The owner's viewer at 1479x519 (scale 1) showed Overview through half of
Accounts above the status card; Assets, Parties, Projects, Documents,
Company and Journal sat in a scroll area with no sign that it scrolled,
so the links seemed to go behind the status box.

The sidebar now gives way in steps, each only when the one before is not
enough, so a window where everything fit looks exactly as it did
(pixel-checked against main at 1440x920, tests/goldens):

1. The status card folds to its one summary line, "● Live · event 559 ·
   ✓ verified". Hovering it shows the three checks; right-click keeps the
   card's copy menu. The line is the fullest wording that fits the card
   (summaries), never cut off: a failed check is named ("⊘ Database
   differs", "⊘ 2 files damaged") before the event and the word "Live"
   are kept, and only then shortened to a count. Whatever the line
   leaves out, its tooltip says.
2. The rows tighten: the footer's menus, the gap under the header, the
   spacing between links, then the rows' height, down to 24 points, in
   the same font. The rail tightens the same way, also to 24 points.
3. Only then do the links scroll, with a soft fade and a chevron at each
   clipped edge (the rail's chevron sits centred on its own pill, clear
   of the icons), and the current page's link is scrolled into view
   whenever the page changes.

Links that overrun their room by under half a pixel count as fitting, so
the card folds where main's links began to lose a visible sliver, not a
point sooner at fractional scales.

At 1479x519 and scale 1 all twelve links show unscrolled in the sidebar,
and at 900x519 in the rail, in every footer state (Live, Snapshot, each
database state, damaged files, no Books menu).

Tests (tests/sidenav.rs, fixture books with a footer like the live one):
every height from 300 to 920 px at scales 1, 1.25, 1.5 and 2, sidebar and
rail, for each footer state: no link under the footer, links cut off only
when they scroll, and nothing scrolls from 519 px up at scale 1; the
owner's window in sidebar and rail; the folded line fits its card and
names a failed check, its tooltip the three checks; the scroll cue and
scrolling to the current link; the tall sidebar unchanged. Unit tests for
fit, its order of steps, the footer's memo and the folded line's
wordings.

Owner, 2026-10-19: full color-scheme support for the viewer, the top
Neovim-style schemes, about twenty families each with a flyout of all its
variants, a light/dark/all filter, Ayu included, alphabetical, a whole row
to click.

- The sidebar's corner button (the light/dark toggle before) opens the
  menu: the filter, then, alphabetically and all on screen at once (in
  columns in a short window), Ayu, Catppuccin, Cyberdream, Dracula,
  Everforest, GitHub, Gruvbox, Kanagawa, Material, Melange, Monokai Pro,
  Night Owl, Nightfox, Nord, One Dark, Oxocarbon, Rosé Pine, Solarized,
  Sonokai, Tokyo Night and Wanderbooks (the viewer's own Light and Dark):
  80 schemes, each variant a row with a strip of its colors.
- Colors from each scheme's official source, checked value by value
  (docs/color-schemes.md; the table names the sources).
- Every palette, the viewer's own included, keeps every text color
  (figures, gains and losses, warnings, links, secondary and faint text)
  at WCAG AA (4.5:1) on every ground it sits on, soft fills included; a
  color that falls short keeps its hue and only changes lightness. Text,
  secondary and faint text stay apart (each 1.2 times the next), gains,
  losses and text and the charts' series shown together stay plainly
  different (CIE76 ΔE 20).
- The scheme sets both egui styles and pins its mode, so the system
  turning light or dark changes nothing (it made figures unreadable).
- Preferences now live in the platform's place for app settings
  ($XDG_CONFIG_HOME/wanderbooks-viewer on Linux), not eframe's default,
  which was $XDG_DATA_HOME/wanderbooks: the data root's own place. The
  old file is moved once.
- Tests: every page of thirteen painted in all 80 schemes, the same words
  in the same places, each text readable on what was painted under it;
  the menu's order, reach and whole-row clicks in a tall and a short
  window; the system flip; preferences restored. Two review rounds.

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.

swaitsandClaude Opus 5.5 8693d5a3f5 MCP: short connect text, a handbook, tool annotations, safe local imports
- The 13K-character instructions (clients cut them short) become a
  connect text of at most 1,400 characters whose first 512 stand alone,
  plus books.handbook and books://handbook/{section}: the old guidance by
  section, with no helper commands, home paths, pull requests or
  file-reading suggestions (tool_text_lint).
- Every tool has a title and read-only/destructive hints; no
  requiresUserInteraction anywhere (owner decision 2026-10-16).
- books.import_local_file reads only regular files inside the import
  roots (the downloads folder by default, or --import-root), never the
  data dir, books dir, vault or the key's folder, no symlink escapes or
  hard links, and the file opened must be the file checked.
- The store lock is a tokio mutex taken off the runtime threads.
- get_info refreshes settings first; a bare books://digest reads.

Review fixes (P0 review, 2026-10-16):
- Fail closed: a tokio mutex never poisons and spawn_blocking caught the
  panic, so after a panic mid-mutation the server kept serving a Store
  behind its journal. A panic (the task, or while holding the store)
  now stops the shared store; every later request on every session is
  refused with a plain message; a restart re-verifies the journal. The
  join error goes through redact_refusal and never carries the panic's
  text.
- books.set_w9 w9_file_path read any path (a link named w9.pdf to the
  vault key was stored and get_w9 wrote it out): it now goes through the
  import roots' lockdown, its type judged on the canonical path.
- Sealed even inside a root: the key file in force, where a linked one
  leads, both folders, and the default key folder whatever the settings
  say. Refusals check the roots first, so outside them every path gets
  one message (no probing what exists); inside, other books-dir files say
  to copy them out first.
- The open is O_NOFOLLOW | O_NONBLOCK (a pipe swapped in after the check
  can't hang a thread) and must match the checked file's device and
  inode. New dependency: libc (unix only), for those two open flags,
  which std doesn't name.
- Default import roots are the downloads folder only (the plan); files
  with full TINs (get_w9, vendor_1099 include_tins, the CPA package with
  TINs) are never written into an import root, and the server refuses to
  import any file it wrote with TINs (by SHA-256).
- set_tin and set_w9 overwrite vault records: destructive_hint = true;
  annotations_complete pins the key tools' hints. The read-only hint is
  checked in behaviour on every spec_mcp call (journal and data-dir files
  unchanged).
- Text: the connect text names the settings file as the one local file
  to edit, says every entry balances on real accounts and names its
  party, says invoice/bill/payment/payroll tools post unchecked, rewords
  the exemptions, and shows the company name as one plain line; the
  handbook takes section "all", lists its ids in the schema and says to
  read contract first; books.settings drops the config.json path and no
  error names the data dir or the key file. tool_text_lint covers the
  whole tool JSON and resources and bans git/commit/FL-0001; tool
  descriptions over 700 characters are pinned to today's eight (P5).
- digest: an empty since= is bare; the default date is pinned on every
  day of a month.

Round-2 review fixes (2026-10-16):
- TIN files (B-26): the in-memory, per-session set of TIN-file hashes
  became one registry beside the vault (vault/tin-files.sha256, hashes
  only), shared by every session and every later server. It holds the
  W-9 set_w9 reads (recorded as read), get_w9 copies, 1099 worksheets
  with TINs, CPA packages with TINs and each file in one that holds a
  TIN; a file is recorded before it is written, and a failure refuses.
  import_local_file, attach_receipt and file_document (base64 was never
  checked) refuse a recorded file, and a text file (by type, name, or
  UTF-8/UTF-16 decoding) holding a full TIN. Not caught: an altered
  binary copy; the docs say so (P2/P7 remove the path tools).
- The text check is narrow (owner/engineer decision, 2026-10-16: bank
  exports are filed for reconciliation, and has_full_tin's "nine digits
  however separated" refused their routing numbers, long references and
  dates run into amounts). Text is refused when it holds (a) a TIN the
  vault holds for a party, anywhere, as nine digits, 3-2-4 joined by
  hyphens, spaces or dots, or 2-7 joined by a hyphen or space, compared
  on the server against the decrypted vault and never returned or
  logged (a vault that can't be opened leaves (b)); or (b) a stand-alone
  printed SSN (123-45-6789) or EIN (12-3456789) shape: no digit, and no
  hyphen or dot followed by a digit, beside it. Full-width digits and
  Unicode hyphens and spaces read as ASCII. has_full_tin still guards
  refusals and results (redact_refusal). Known limit, for P7: a refusal
  under (a) tells the agent a text it chose holds a vault TIN.
  New dependency: zeroize in ledger-mcp (already in the workspace
  through ledger-vault, same major version), so the vault's TINs decoded
  for the scan are wiped from memory on drop as the vault's own are.
- Mutation testing of the final P0 diff (docs/testing.md): tests for
  each law a survivor broke (handbook titles, a dropped default root, a
  .jpg W-9, the waker, the walk's folder flags against a link and a
  pipe, the 40-link limit, save paths refused as such, the package
  marking only its TIN files, a registry that can't be read, text types,
  the short receipt rule's counts and a 12-character code). Simpler
  code where only a race could tell: inspect places an existing path by
  canonicalize itself (no second comparison), read_checked's read limit
  is its one size check, openat fails on -1 as specified. The 25 MiB
  upload test removes its 50 MB of books however it ends.
- The GUI's stale-rule prompt no longer says to open a pull request: it
  asks the agent to find the figure from the rule's official authority,
  confirm it with the human, pass it explicitly, and tell the human so it
  can be reported upstream (as the handbook says); a lib test pins it and
  bans files, git, GitHub and pull requests from every attention prompt.
- Import roots (local_files.rs INVARIANT 0): XDG_DOWNLOAD_DIR="$HOME/"
  made $HOME (or /) the root. No root may be /, the home folder or hold
  it, or hold the books, data dir, vault or a key: a named one stops the
  server at startup, a default one is dropped; the default falls back to
  ~/Downloads only if that is a real folder other than $HOME; with no
  root, an import says so.
- The read is a component walk from / with openat(O_NOFOLLOW |
  O_DIRECTORY) per folder and O_NOFOLLOW | O_NONBLOCK for the file, so a
  folder swapped for a link after the check fails; no step may land on a
  protected inode (one renamed into a root); dev/ino and nlink stay. No
  /proc. Portable to macOS. (libc's openat, two small unsafe blocks.)
- One refusal for missing, dangling and outside paths: resolved()
  follows every link, dangling ones too, so a link's target existing or
  not no longer changes the answer.
- Sealing: the key files (in force, default) and their targets always;
  their folders only when not $HOME, not a root, not holding a root; and
  ~/.config/wanderbooks whatever XDG_CONFIG_HOME says.
- Agent text (I-12): RuleNotKnown names the authority (IRS, with its
  address) and says to tell the human, never a repo path, PR or GitHub;
  the digest's stale_rules drop the repo catalog and path for it; vault,
  outside-books, STOPPED and local-file refusals name no git, path or
  flag. tool_text_lint bans docs/, .md, /home, data dir, --data-dir,
  --import-root, vault.key, .jsonl, sqlite, .gitignore, github, pull
  request, and also lints every error template (scanned from source),
  built error texts, and the server's refusal constants.
- The receipt rule told (ReceiptPolicy::rule) is the one enforced: the
  exact threshold in the base currency (no "$", no rounding), required
  and exempt accounts, reversals exempt; the connect text fits 1,400
  characters by dropping reasons, then codes, never the rule.
- The connect text follows the parties setting; "offer books.digest"
  everywhere. shown_name drops Unicode format characters (bidi, zero
  width).
- read_only_tools_change_nothing compares file contents, the database
  by every row, the vault and the settings file (raw database bytes did
  not change either; rows are the stable comparison).
- import_local_file takes the name and type from the canonical path;
  the digest's journal repair says when the tail was set aside, not the
  journal's file name; "version-history messages" back in the TIN rule;
  openWorldHint false on every tool, pinned in annotations_complete.
- Outside the MCP crate, for the same texts: ledger-core's DatedRule
  gains `authority` (the statute or publication with its address) and
  RuleNotKnown carries it; ledger-store's "sqlite error" reads "database
  error"; ledger-config's ReceiptPolicy::rule takes the base currency.
  New dev-dependency: rusqlite in ledger-mcp (already in the workspace,
  same version and features as ledger-store), to read the database's
  rows in read_only_tools_change_nothing.
- The filing scan is no TIN oracle (tin_files.rs INVARIANT 4): text
  holding more than two TIN-shaped numbers (any rendering rule (a)
  reads) that end in a known TIN's last four (the books' TIN and W-9
  facts, via known_tin_last4, before the vault is opened; then the
  vault's own) is refused with TIN_PROBE, the same words whether or not
  one is the vault's TIN; only one or two candidates are compared
  against the vault. Tests: unit
  text_probing_for_a_tin_is_refused_alike_whether_or_not_it_holds_it,
  one_or_two_candidates_are_compared_against_the_vault; over HTTP
  text_probing_for_a_tin_is_refused_alike_by_every_filing_tool.

Plan: plan/served.md P0, section 6 "Immediate hole (P0)", 4.1, 4.3, 4.9.

Review round 3. S1: a panic stops the server for every session, so no
input may reach one. Dates are four-digit years (new ledger_core::
calendar, 0001-01-01..9999-12-31): the MCP's parse_date is strict
YYYY-MM-DD, periods are bounded, last_day_of_month returns a refusal
(server and store); schedules, assets, recurring entries, periods,
documents, disposals and entries refuse dates outside the calendar, and
replay refuses such journal dates. Every amount a command takes is at
most a line's (draft lines by size, document lines, payouts, payroll,
statements, shares, tax basis, proceeds, recurring templates), on
replay too, so sums are exact; the 1099 vendor part and the K-1
property share use checked products (TooLargeToCompute); a recurring
run makes at most 1,000 drafts. tests/hostile_args.rs drives every tool
with schema-derived hostile arguments and every resource with generated
URIs, asserting the server never stops; the audit's panics are pinned.
S2: a `.` or `..` path name is refused as NO_SUCH_FILE up front. S3:
NUL-interleaved UTF-16 without a byte-order mark is scanned both ways.
S4: resource-read refusals are TIN-redacted. S5: set_w9 records its W-9
only once the call passes every check, just before the vault write.
S8: idempotentHint only on verify, run_depreciation, run_schedules,
run_recurring, set_party_roles (a repeat leaves journal and vault
alone; spec_vault checks every candidate twice); every tool's hints
pinned in one table. C1: books.settings lists receipt_required_accounts
and receipt_exempt_accounts uncut. C2: the default company name reads
"a new company". C3: the parties rule names no-party reasons. C4/C5:
the handbook names the settings file only as books.settings' books_toml,
and restores "check books.digest and offer it". C6: an import root
inside the books, data dir or vault is refused at startup. The lint
catches `just` however it ends and where the books are;
digest_resource_bare_reads reads the server's month.

Review round 4 (2026-10-17): round 3's bounds ran in replay too, so
journals main wrote and reopened (an entry dated 0000-06-01 or
+10000-01-01, a draft line of 2e15, an asset ending past 9999, a basis
or share past the line limit, sub-cent document and payroll lines) no
longer opened. Posted is forever: the bounds are the commands' only.
- Replay applies main's rule exactly: parse_date takes any date chrono
  reads; replay_add_line(_fx) has no size bound (add_line/add_line_fx
  do); replay_register_asset/correct_asset (chrono overflow only),
  replay_set_asset_tax_basis (check_journaled), replay_set_entry_parties
  (check_shares_journaled), replay_register_recurring
  (validate_recurring_journaled), replay_register_schedule (months 1 to
  600), replay_create_period (order only), replay_dispose_asset, and no
  line, date, payment or payroll range checks in replay_invoice/bill,
  their payments and replay_payroll_run.
- Derived figures over such books refuse (TooLargeToCompute,
  DateOutOfRange), never panic: amortization plans, depreciation into
  chrono's last month (and the true-up for lives past 9999), intervals,
  document totals and aging, net pay and payroll plans, money flows and
  share resolution, the asset register, receipt-policy debits; the MCP
  tools and the viewer show what can't be computed.
- tests/fixtures/old-books: the review's 13 journals, its control and 15
  more edges, written by main's Store API with main's figures
  (expected.json); every one opens in the writer and the viewer to those
  figures, every derived figure computes or refuses, every MCP tool and
  GUI page answers; hostile_args restarts the server after each
  property; each bound has a command/replay test pair.

Final review: a schedule's plan refuses a total of 10^26 or more
(TooLargeToCompute) instead of letting Decimal round its cents silently,
and a null `remaining` in the schedule output is always explained by
plan_error. Replay is unaffected: no journaled schedule month can belong
to a total that large (the line limit bounds every posted month).

swaitsandClaude Opus 5.5 9f9f00ed9a Store: say "newer wanderbooks", not "corrupt", for books from a newer version
An unknown event type on a whole, chained line, or a journal.format_set
declaring a newer journal format, now raises StoreError::NewerJournal
(update wanderbooks) instead of JournalCorrupt. Corruption (bad hash,
seq, or JSON) is still corruption. The gate runs in the store, the
Snapshot and the GUI, after each line's parse, seq and hash checks, and
never skips a line it can't read. Adds the journal.format_set event
(format 1 today; nothing writes it yet) and a registry of every event
type this version reads, tested against the replay and projection arms.

Review fixes (P0 review, 2026-10-16):
- A line's own hash is checked only by the next line's prev, and the
  gate used to refuse a line before reading the next: a flipped bit in a
  middle line's type (or a format_set edited from 1 to 2) was reported
  as "newer, the books are not damaged". Now the reader settles every
  refusal against the next line (format::settle): a next line that
  doesn't chain makes it corrupt; one that chains makes it newer and
  verified; with no next line the message says "newer or damaged; update,
  then run verify", never "not damaged" (NewerJournal.verified).
- A newer format number is judged newer before its features are parsed:
  a newer format may shape them differently.
- Snapshot treats a blank complete line as corrupt, as the writer does.
- docs/spec/rules.md B-27, which the code cites, now exists.

Round-2 review fixes (2026-10-16):
- The envelope {seq, ts, type, payload, prev} and its hash (SHA-256 of
  the canonical JSON) are frozen across formats (rules.md B-27); new
  fields go in payload. settle reads only the next line's prev, leniently,
  so a newer format's next line (a float, a string seq, keys of its own)
  is never called corrupt: no readable prev means unverified newer.
- A key beside the envelope's was silently dropped (and the chain then
  broke as "corrupt"): it is now NewerJournal, hashed over the raw
  canonical JSON so the next line still checks it; JournalLine::parse
  refuses such a line.
- "the books are not damaged" overclaimed: a verified refusal says line N
  is intact and this version can't check the lines after it.
- The writer read the journal with BufRead::lines (invalid UTF-8 was an
  I/O error); it now splits bytes on newlines as the Snapshot does, so a
  non-UTF-8 line is JournalCorrupt in both.
- Store::open truncated a torn tail before the gate ran, altering newer
  books (perhaps mid-append) before refusing them. The gate now runs over
  the complete lines first; the tail is set aside (and journaled) only
  when they pass.
- Mutation testing (docs/testing.md, P0): the viewer and the writer say
  the same words about the same damaged line (the newline is no part of
  it); read_journal_and_format returns every line and the format in
  force; the journal page tells a format declaration.
Plan: plan/served.md P0 and 5.1.

Review round 3 (S6, S7). Store::open replays every complete line in
memory (the first line's currency, then the ledger) before a cut-off
last line is set aside, so a complete line the books can't apply
refuses the open with the journal byte for byte as it was and nothing
set aside (B-27 SCENARIO 3; test
a_bad_complete_line_before_a_torn_tail_leaves_the_journal_as_it_was);
catch_up now only projects. The viewer
applies the writer's first-line rule (created_currency, shared) instead
of guessing USD: any other first line, or a store.created without a
sound base_currency, is corrupt to both (test
the_first_line_is_store_created_for_the_viewer_and_the_writer). fuzz_store_replay varies the
first line (14,696 runs clean).

The party page's "TIN on file" and the W-9 card's TIN copy the full,
formatted number on click (right-click: digits only). The viewer reads
it from the vault only at that moment, with the server's key file in
force, never creates a key, refuses a key inside the books dir, and
never draws more than the last four. A locked vault copies nothing and
says why.

swaitsandClaude Opus 5.5 8498e6cfab Audit fixes: party money, reconciliations, require policy, K-1 property
An independent recompute of the real books found no numeric
disagreements; review found 15 defects, all fixed with spec-first
regression tests:

- k1: a prepaid credited straight to capital is property; a member
  paying a vendor through 2100 is cash. Docs and B-13 match.
- parties: a reversal of a reversal counts on its root's side;
  liability-to-liability payments (member pays the card) count as paid.
- viewer: party money uses the server's cash accounts and full calendar
  year; per-party "What for" scales multi-party entries.
- reconciliations: refuse a withdrawn statement before journaling; new
  books.void_statement; reconciled lines can't be un-cleared; one shared
  reconcilable-accounts rule for digest and viewer.
- CPA package includes receipts linked to entries; a file can't be both
  filed on and linked to one entry.
- parties = "require" covers payroll, tax remittance (agency) and
  disposal (buyer); no-party marks follow reversal chains and clear when
  a vendor is tagged.
- derived member shares are frozen to exact amounts when posted, so a
  settings change never re-splits history.

swaitsandClaude Opus 5.5 e1b2509c22 Shared parties with exact shares, member capital statements, TINs for any party, K-1 worksheet
Entries may name several parties, each with an exact amount, a percent,
or a share derived from the members' capital lines or [[company.members]]
shares (entry.parties_set); shares always sum exactly. The 1099
worksheet counts a vendor's share. A member's party page is their
partner capital statement, from the same ledger_core::k1 source as the
CPA package.

books.set_tin stores any party's TIN (members' SSNs for K-1s) in the
vault (party.tin_set, last four in the books). The CPA package carries a
K-1 member worksheet (k1-members.csv, with a members' total that ties to
Schedule L) and the 1099 worksheet with full TINs, saved outside the
books only. files_jointly_with notes spouses' two K-1s land on one 1040.

Adversarial review fixes: reversed contributions no longer inflate K-1
contributions and distributions; a K-1 row never takes another party's
TIN; TIN detection covers dot/slash/dash separators; refusals redact
TINs; vendor tagging can't silently replace shared parties; reversals
follow re-apportioning.

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.

swaitsandClaude Opus 5.5 21292a70b8 viewer: the overview's numbers checked against ledger-core
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).
