- 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/WL-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).

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.

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.

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.

ledger_core::parties::entry_flow: cash lines count; liability lines count
except the part paired against cash in the same entry, which counts once

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

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

Company details (EIN, state number, address, every profile value), an
entry's number and amount, an account's code and balance, a document's
file name and SHA-256 copy on click: a pointer and copy icon on hover,
a check for a moment after. Amounts copy as their exact plain decimal
(fmt::plain: no "$", commas, or parentheses; "-" for negatives); where a
click already drills down (report cells, register and transaction rows,
general ledger lines), a right-click menu copies the amounts, the entry
number, or the description. The sidebar's chain check copies the
journal head and data folder.
tests/copy.rs: every display style copies back to the exact value
(property), and clicking the EIN, an entry's amount, and its number puts
exactly that on the clipboard.

tests/read_only.rs: with every file and folder of the books read-only on
disk, the viewer loads, follows live, and renders every page (receipts
included), and every file keeps its bytes, size, and mtime; on writable
books nothing appears beside the database either.
Found: with no writer running, the snapshot's read-only open of the WAL
database had to create -wal/-shm (a write into the books) and failed on
read-only books, showing a false "database unreadable". With no -wal
file no writer has it open, so check_disk now reads it immutable.
just mutants-gui sweeps only what the viewer must get right: the view
model's numbers (books.rs) and their formatting (fmt.rs); 179 mutants.

tests/spec_gui.rs (31 spec-blind tests): exact money text round-trips,
file names never escape the folder or hit a Windows device name, history
against a browser model, fuzzy search against a subsequence model, axis
ticks, the view model against ledger-core, and the attention list.
Found and fixed:
- fuzzy matched greedily, so "ac c" scored 1 for "c" (the "c" inside
"ac") instead of 5 for the word "c"; it now scores the best alignment.
- ticks accumulated float error (a last tick at -5.55e-17 for a top of
0), gave more than n + 2 ticks at large magnitudes with tiny spans,
and overflowed for spans near f64's limit. Ticks are now whole
multiples of the step, checked, with [lo, hi] when f64 has no nice step.

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).

Ledger::renumber_account changes only the code (entries name accounts by
id): refuses an unknown account, a blank or used code, and a control code
for an account of the wrong type or a placeholder. Journaled as
account.renumbered (with the previous code), replayed, projected, shown
in the viewer's journal. The MCP tool lists wanderbooks.toml settings
that still name the old code. The server instructions now warn that the
engine can't tell a same-type account with another purpose at a control
code (a hosting expense at payroll's 6100).
Tests: core property (only the code changes; trial balance equal), core
refusals, the store's command property, MCP end to end with restart.
Mutation on the new code: 8 of 8 viable caught.

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.

New concurrency test: one thread writes entries, drafts and receipts as
fast as it can while a Snapshot (the viewer) refreshes in a loop. At
every refresh the snapshot's books must balance, never go backward, and
never see the writer's database as differing from the journal; at the
end it must equal the writer in full. It failed 30 runs in 50:
check_disk read the applied position and the tables in separate
statements, so a write landing between them made a consistent database
look like it "differs", which the viewer shows as a problem in Needs
attention.
- check_disk reads in one read transaction (one consistent view).
- A database that has applied lines the viewer hasn't read yet is now
DiskCheck::Ahead ("viewer catching up"), not Behind.
- Without the transaction the test fails 14 runs in 20; with it, 50/50.
Also: members' equity spec 3b states the exact bound (a member's period
income is within two cents of their share, one cent of rounding at each
end; the running balance chains exactly), and the spec-blind property
checks that bound. docs/testing.md gains the concurrency layer and item
12: each close into members' capital still rounds on its own (pending).

From ASC 230 (via Deloitte DART and PwC Viewpoint), replacing two
formerly assumed behaviors:
- Financing and investing are gross (230-10-45-7): per account, cash in
and cash out are separate lines (contributions apart from
distributions, borrowing apart from repayment), netted only within
one entry. Lines come in code order, in before out.
- Investing includes making and collecting loans and buying investments
(230-10-20, 45-13), not only registered fixed assets:
CashFlowParams gains investing_accounts.
- The roles are per-company settings: [books] financing_accounts and
investing_accounts in wanderbooks.toml (beside cash_accounts). The MCP
tools (cash_flow, export, CPA package) default every list to them and
share one path; the viewer reads them too, falling back to its name
guess for debt. A due-to-owners liability listed as financing gives
PwC 6.9.3.1's constructive treatment of expenses an owner paid.
rules.md B-14 quotes the sources; new tests cite them; docs/testing.md
#8 is resolved.

A crash or power loss mid-append can leave a partial last line. The
writer acknowledges an append only after its whole line is synced, so
that line was never acknowledged: opening now saves those bytes to
journal.jsonl.torn.<time>, truncates to the last newline, and journals
journal.tail_repaired (replay and projection ignore it; the GUI shows
it; books.digest reports it in journal_repairs). Damage before the last
newline is still corruption and still refuses to open. Tested at every
byte of the last append.
The MCP server now waits up to ten seconds for the writer lock: a
restarted server (a client reconnecting) raced the exiting one and died
with Locked, which also made mcp_schedules_and_recurring_over_stdio
flaky. The test harness now waits for each server to exit.

Stephen (2026-10-13): when what wanderbooks knows is stale, check the
date, research it or ask the owner or CPA, and update the rule for
everyone with a pull request (best) or an issue (worst).
- ledger_core::rules: a registry of rules set by law that change over
time. Each says the years it's known for, its rules.md entry, its
vendored official source, and a review date. stale_rules(today) is
pure; the engine has no clock.
- The 1099 threshold is the first: $600 through 2025, $2,000 in 2026,
then indexed for inflation (26 U.S.C. §6041(h)). default_threshold
and vendor_1099_report now return Result; for 2027+ they refuse with
LedgerError::RuleNotKnown, whose message says what to do: get the
figure from the official source or the owner/CPA, pass it explicitly,
then open a PR (or issue) at github.com/swaits/wanderbooks. Before,
2027+ silently used $2,000.
- MCP: books.vendor_1099 relays that refusal; books.digest gains
stale_rules; the server instructions tell the agent the procedure (and
how to handle control-account conflicts: explain, never renumber).
The CPA package writes a NOT-INCLUDED note instead of a guessed 1099
worksheet.
- Viewer: "Needs attention" shows each stale rule with a ready prompt
for the agent; the 1099 page explains instead of guessing.
Review date for the 1099 rule: 2026-11-01, when the IRS usually
publishes next year's inflation adjustments (CONVENTION, marked as such
in the registry).
Tests: an_unknown_year_threshold_is_never_guessed,
dated_rules_go_stale_on_their_review_date (dates passed in, so no clock
in the test), MCP stdio: 2027 refused with guidance, explicit threshold
accepted, digest carries stale_rules (asserted date-independently).

The general ledger draws its own per-account tables, so it had no PDF
button. It now has one: each account a section, a line per posting
(date, entry, description, the other side) with debit, credit, and
running balance, its beginning balance, and totals with the ending
balance, typeset through the same statement template.
The PDF plumbing (button, status, background job) is shared by both
paths now. The ledger's rows also measure and clip their text and
scroll sideways in narrow windows, like every other table.

Reports get a Save PDF button beside Copy for a spreadsheet. It typesets
the report as it's set up on screen (range, months/quarters/years,
comparison) through ledger-import's Typst statement template, the same
one the CPA package uses, in the background, writes it to the Downloads
folder (never the books: the viewer stays read-only), and opens it.
- ledger-import: Statement.percent_from marks percentage columns
(comparison %, % of income), typeset as 12.5% with no dollar sign;
wide statements turn the page, and past seven columns set smaller so
a year of months fits; statement() is public for other callers.
- Compared columns that read the same (Jan 1 - Oct 12 vs a year
earlier) now say which year, on screen and on paper.
- Short windows: the sidebar's and rail's links scroll above the status
box instead of under it. The search palette fits the window.
- A test typesets every table-backed report from the demo books,
plain, by month, and compared (PDF_DIR keeps the files).

Narrow windows overlapped and clipped: the top bar's crumb, date, and
search ran into each other; big numbers wrapped mid-figure; tables
painted columns over each other; the entry and document panes squeezed
their lists to slivers; anything too wide widened the whole page.
- Below 1000 points the sidebar becomes an icon rail (names, attention,
and integrity checks in tooltips).
- The top bar lays out right to left: search shrinks to its icon, the
date drops, the crumb truncates.
- Pages are pinned to the window width with narrower margins when tight,
so one wide thing can't push everything off screen.
- Tiles (KPIs, cash accounts, documents) fit as many columns as the
width allows, balanced across rows; KPI figures shrink rather than wrap.
- Painted tables shrink their amount columns, clip labels with an
ellipsis, then scroll sideways rather than overlap.
- List/detail splits show only the detail when both won't fit.
- Reports: the side list becomes a picker; controls wrap by known width.
- Smaller fixes: chart labels thin out, company facts stack, journal
timestamps yield, transaction filters become a dropdown.
- Min window size drops to 360x400; the screenshot test covers every
report, a register, a document, and a journal event.

report (dates, month/quarter/year columns, prior-period or prior-year
