swaitsandClaude Fable 5.1 6b7dccd1ee feat(audit): audit runs and attestations are journaled (P8)
A claim that someone checked the books is evidence the CPA handoff rests on,
so it is a journal fact and replays: audit.run (a programme run through a
day at the books' figure head, with the hashes that make it reproducible and
the two filed workpapers), receipt.attested, entry.reviewed and
period.attested. Behind the journal feature audits, schema 20; no figure
moves. The figure head is the last line that bears on a figure: filing a
workpaper, a run or an attestation never makes an audit stale, an entry,
document, close, settings or role change does, so a period is attested only
on an audit that still describes the books. A receipt reading that differs
from the entry is recorded as disagreeing and never counts; whether a claim
counts is derived against the bar when asked, never stored.

The store also reads what a ledger cannot: the chain, the database against
a replay, stored and extracted files, the access log, duplicate files, and
the backups' standing handed in by the server. Fixture old-books/p8_before
was written by the version before this one and opens to its figures.
period.attested was the tests' placeholder for an unknown event type; they
use ledger.not_yet_written now.

swaitsandClaude Fable 5.1 61da9e57cd feat(mcp): books.journal_history, the journal in words (P5)
Agent reason: an agent traces a figure back to what produced it by reading
the journal, but it must never read the file. books.journal_history is the
one way: each line in order with its seq, time, type, a sentence saying what
it did to what, its subject and the entry it belongs to, filtered by
after_seq, type (exact, or a group like entry.) and subject (entry:12,
invoice:3, bill:3, account:10, party:5, asset:2), paged with more, with the
torn tails set aside on open listed beside them. It reads the verified
journal through read_journal_and_format, so a damaged chain is an error, not
a story.

The sentences come from ledger-store's describe.rs, which quotes only
identifiers, dates, amounts and the short names a person typed: never a
setting's value (settings.set names its keys) and never a full TIN (masked,
B-26). Every event type the store writes has a sentence (tested against
EVENT_TYPES). The tool is read-only (books:read); the books://journal/{seq}
and books://entries/{id} resources read through it.

Departure from the plan: the viewer's own sentences (its describe arms in
ledger-gui, which carry icons, routes and today's party and account names)
stay where they are; moving a thousand lines of egui text behind a
formatting trait was not worth the risk to the viewer's tests, so the server
has the shared describer and the viewer keeps its own.

swaitsandClaude Fable 5.1 2ad192bbcd merge: P6, the evidence pipeline (branch P6, checkpoint ce366408)
The last of the paused branches, from its "not for merge" checkpoint:
extraction in ledger-import (text, pages, page images; capped, caught),
journaled as attachment.text_extracted; dedup by hash with
books.find_attachment and books.consolidate_duplicates; annotations and
books.set_entry_settles; the company record categories; the two fuzz
targets; feature attachment_text. Nineteen files conflicted with the
four P4b merges, resolved as plan 8.0.2 says: P6 retakes schema 18 (it
had taken 16, which S4.3 holds; S5 holds 17); the tool table is 129 and
the destructive count 31; both sides' appends kept with their seams
restored; one B-27 paragraph naming every feature; in the old-books
fixture P6's hand-written reimbursement is entry 7 (its ids collided
with S4.3's invoice); the replay fuzzer's list gains S7's
invoice.written_off; S4.3's issued-PDF test expects the extraction
record P6 journals right after a filing.

One integration defect between S7 and P6, found by the arap property
test and fixed here: under P6's dedup, a write-off whose evidence bytes
were filed already (the same collection letter for a second write-off of
the same invoice) was refused only after its entry had been journaled,
at the final link to the invoice ("already linked"). The write-off now
resolves the dedup before anything is journaled and keeps a link the
record already has to the invoice instead of refusing it; an explicit
existing_attachment_id already on an entry is still refused (S7's
one-receipt-once rule). P6's gate never ran before the pause; it runs on
main after this merge, and its ledger-store -> ledger-import dependency
is the open review point (plan 8.0.1).

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.

swaits ce36640874 wip: pause checkpoint — P6 feature complete, gate interrupted (not for merge) 2026-10-27 14:41:34 -06:00
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 4e71cf6320 feat(store): journal a write-off with its evidence (P4b S7)
A bad debt is deducted on evidence it is worthless (Treas. Reg.
§1.166-2), so the store will not journal one without it:
Store::write_off_invoice takes the evidence as bytes to file or as an
attachment already filed, and files it in the same call — a
receipt.attached on the write-off's entry and an attachment.linked to
the invoice (rules.md B-41). With no evidence it refuses, journaling
nothing.

The entry (Dr 6990 Bad Debt Expense / Cr 1200) and its evidence are
journaled after the engine's whole check and after the feature gate: the
new event type invoice.written_off needs documents_v2, so an older
version stops at the declaration rather than reading a written-off
invoice as still owed (B-27, D-52). Its payload is the invoice, the
entry, the day, the amount and the reason; replay tags the receivable
line WriteOff, and the projection keeps no written-off figure — it is
the tagged lines' sum (B-38).

`meta::invoice_written_off_of` reads and writes the payload; the replay
fuzzer draws the type.

8.0.6: (1) `books_written_under_older_rules_still_open` hand-writes the
new event and its entry through JournalWriter and still opens, with the
figures tailing; (2) a new fixture old-books/p4_s7_before was written by
main 4cad2cfc (the version before this unit) through the old-books-writer
harness — a numbered invoice with terms and snapshots, a partial payment,
a voided invoice and a paid bill — with its expected.json; this version
opens it and reports the same figures, the viewer included; (3) the
cut-over entry is in format_upgrade.rs's books_p2_served_cut_over_whole;
(4) documents_v2_is_its_own_feature is green and the event gate's arms
pass; (5) no figure moves: no golden changed (the previous version's
expected.json is the comparison); (6) merge does not need the owner's
go-ahead; the live books refuse the new write until he gives it.

Tests: write_off_waits_for_documents_v2, write_off_replays_and_projects,
write_off_without_evidence_is_refused; arap_props.rs gains WriteOff.

swaits d5b9e5cf99 feat(mcp): the create tools preview and confirm, and the party keeps its contact block (P4b S4.4)
An invoice is issued, not edited. Without `confirmed` the create tools now
preview: the posting (with the accounts' codes, which the live chart may
not hold yet), the number it will take, its due date, terms and early
discount, warnings, and for an invoice the DRAFT copy of the PDF, handed
over as a file. Nothing is written and no number is used up. With
`confirmed` the invoice posts, takes the number the preview showed, and
files the issued copy with itself in the same call: `receipt.attached` on
its entry plus the link to the invoice, its SHA-256 in the event (A-1,
A-7, B-40). The copy the customer received is therefore the copy in the
books, and `books.document`'s re-created page can never be mistaken for
it. The result also carries a `mailto` link for a human to send it; the
books never send (A-4).

A bill keeps what the plan says a bill is: the vendor's own invoice
number, the vendor's invoice filed on its entry as its evidence, and, in
books that have declared `documents_v2`, an account on every line, so no
bill can land in General Expenses by default any more (A-9, A-10, A-13).
A vendor number entered twice is refused unless the caller says why, and
the reason is journaled with the second bill (B-40 item 4). Books that
have not declared the feature keep recording bills exactly as before, so
the owner's books keep working between units (D-39, 8.0.4).

Terms are resolved in one place and in one order: the due date given,
else the terms given, else the customer's or vendor's own default, else
the books' `invoicing.default_terms`; a document given only a due date
stores no terms, so an old-shape invoice is still written byte for byte
as before (B-39, A-13).

D-55: a party carries the owner's full contact block (phone, contact
person, billing and shipping addresses, billing email). It rides the same
`party.updated` event behind `documents_v2`, and an invoice's bill-to is
snapshotted at issue with the billing address and billing email in place
of the general ones when the party has them — `PartySnapshot::from_party`
is the one place that rule lives, so a later edit cannot change what was
sent, and the next invoice takes today's details.

Tests: the wire tests are the new `crates/ledger-cli/tests/documents.rs`
(preview writes nothing, the DRAFT copy, the issued copy's SHA-256 equals
`books.get_receipt`'s, numbers run, a bill's file and terms, the duplicate
refusal, the line-account rules, the terms fallback, the `party_id` alias
and the ambiguity it refuses, the contact block's set and clear, and the
bill-to at issue); `format_upgrade.rs` gains
`documents_v2_refused_until_consent` and the cut-over test now refuses and
then makes a document carrying a new field (8.0.6 item 3); the store
tests are `the_contact_block_round_trips_and_replays` and
`an_invoice_keeps_the_billing_details_it_was_issued_with`, and
`books_written_under_older_rules_still_open` gains a hand-written
contact-block event (8.0.6 item 1).

Merge does not need the owner's go-ahead: the live books refuse a write
that needs `documents_v2` until he gives it, and take every other write as
before (8.0.6 item 6). No figure moved: S4 moves none.

swaits 0e5aebda99 feat(store): journal the document fields and file the issued PDF (P4b S4.3)
S4.1 gave documents a number, terms, line accounts and snapshots, and S4.2
gave parties an email and default terms, but the store journaled none of
them: a document carrying one was refused by a temporary guard, because a
public write that replay loses would break I-3. This slice makes the
journal carry them.

- `invoice.created` and `bill.created` write a number, terms, bill-to and
  seller snapshots, references, memo and a duplicate's reason, and each
  line its account, quantity and unit price, every key only when set. A
  document naming none is journaled byte for byte as every earlier version
  wrote it (`no_new_fields_journals_byte_for_byte`), so the owner's live
  books keep working.
- All of it is behind `documents_v2` (B-27): a write that names one waits
  for the owner's upgrade, refused with `format_upgrade_pending` and
  journaling nothing; a write that names none never waits
  (`documents_v2_waits_for_the_upgrade`).
- `invoicing.first_number` is settable only while no numbered invoice
  exists (A-2, B-40): the series has begun, and a number is never reused or
  renumbered. Refused at `set_setting`, before anything is journaled.
- The issued copy is filed in the issuing call (A-7, B-40 item 3):
  `create_invoice_issued` journals the entry, the invoice, then
  `receipt.attached` on that entry (`INV-0007.pdf`, `application/pdf`,
  "Issued invoice") and `attachment.linked` to the invoice. There is no
  `issued_pdf` field: the attachment id is allocated after the entry exists
  (CD-A6), and the link is how the copy is found and how its SHA-256 is
  checked. Every refusal happens before the first journal line; the PDF's
  bytes are stored before it, so a refused issue leaves an unreferenced,
  deduplicated blob at worst.
- A preview runs the issue on a clone and journals nothing: the posting,
  the total, the number it would take and the due date (`preview_invoice`,
  `preview_bill`). Books that haven't upgraded keep the legacy shape: the
  copy is filed as "Invoice {id}.pdf" and no number is taken (migration
  item 5).
- Schema 16 adds the document columns; a line's new fields ride
  `lines_json` as its project does. `differs_from` already compares whole
  invoices, bills and parties, so it sees every new field.

8.0.6: (1) `books_written_under_older_rules_still_open` hand-writes both
new document shapes through JournalWriter and still opens; (2) a new
fixture `old-books/p4_s43_documents` was written by main d5385a7e (S4.2,
the version before this slice) through the old-books-writer harness, with
its expected.json; this version opens it and reports the same figures;
(3) see the note on R-A step 4 in the PR (the over-the-wire document write
needs S4.4's arguments; S4.2's invoicing-setting entry already covers the
feature's cut-over); (4) `documents_v2_is_its_own_feature` is green; (5) no
figure moves: no golden changed; (6) merge does not need the owner's
go-ahead; the live books refuse the new writes until he gives it.

just check green (no kernel function, Lean theorem or Ledger command, so no
`just prove` change).

swaitsandClaude Opus 5.5 3a9aa92315 P3: the books' format moves only with the owner's go-ahead (D-39)
Books an update could write a newer format for open on their old format
and are asked at every open; anything needing a new feature is refused
until the owner agrees with the passphrase, after a verified backup that
includes the keys. New books start on the current format. Each projection
schema has its own database file, so an older version still opens the
books until the owner agrees.

swaitsandClaude Opus 5.5 d5c9522ad1 P2: tests mutation found, three bugs fixed; plan P12 and P13
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.

after a quiet spell, before they close and on request; every commit,

and after a failure. `wanderbooks books restore` previews, then
restores beside or (with --replace) over, never moving books something
holds. The archive refuses anything but a plain bare repository and
pins git against the owner's configuration. books.backup and

link, another user's, open to others, unmarked, or under a folder another
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.
wanderbooks setup makes the root and never prints where it is. Three

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

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).

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.

Parties: one directory for vendors, contractors, customers, employees,
members, platforms, agencies, banks, landlords (ledger-core parties.rs).
W-9/W-4 facts without the number (last four only; any nine-digit run in a
party field is refused, Treas. Reg. 301.6109-4). Vendor and customer
records link to parties on replay; core tags every bill, invoice, payment,
and reversal with its counterparty. Journal events party.*,
entry.party_set; payroll lines name the employee party.

MCP: books.add_party, update_party, set_party_roles, set_w9, set_w4,
parties, party, set_entry_party; draft_entry party; run_payroll employee;
show party. Viewer: Parties directory and party pages, search, journal
text, W-9 attention, demo data.

One definition of a party's money (ledger_core::parties::activity) for
MCP and viewer. 1099 amounts count payments from cash and financing
accounts (a member paying for the company counts; a card doesn't; a
prepayment counts when made): vendor_1099_report_with, B-19.

Store: attachment links to any subject, statements, reconciliations
(schema v11), with replay and projection. ledger-vault: encrypted TIN and
W-9 records (ChaCha20-Poly1305, key file outside the books).

Spec-blind tests for parties (core, store, MCP, viewer) and attachments.

swaitsandClaude Opus 5.5 b2b49267db fix(store): one writer at a time; a second is refused, not allowed to corrupt the books
Max-testing pass on ledger-store, found during the survey: nothing
stopped two processes from opening the same books for writing. Two
agent sessions (two MCP servers) on one books dir would each extend the
hash chain from the same last line; one write from each broke the
journal ("seq gap: expected 3, found 2") and the books would not open.

The store now holds an exclusive lock on books-data/wanderbooks.lock
(std's File::try_lock, no new dependency) from before it reads the
journal until it is dropped; the OS releases it if the process dies. A
second writer gets StoreError::Locked saying another process has the
books open. The viewer reads through Snapshot and never takes the lock.
The lock file is git-ignored in the books scaffold.

Regression: a_second_writer_is_refused_while_the_first_has_the_books
(refused while open, allowed after close, books whole).

swaitsandClaude Opus 5.5 c16899f5d6 feat: books.show — the agent puts things on the viewer's screen
books.show asks the viewer to open an entry, an account register, a
report (dates, month/quarter/year columns, prior-period or prior-year
comparison), a document, a search, or a page. The request lives outside
the books (runtime dir, keyed by data dir, written atomically); the
viewer watches it beside the journal and applies books before
navigating. 66 tools.

Site: the dashboard is the hero again; 'Here's what using it looks like'
shows the session beside the viewer, ending in books.show; the cash page
replaces the repeated overview lower down.
