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 453abb62ea feat(mcp): books.start v2 and the agent's self-report (P5)
Agent reason: the first call of a session should say who is asking, what is
waiting and what to do, in under 8 KiB, from the same lists the viewer
draws. books.start now carries book.id and book.url (the book's path on the
server, never a path on a disk), you {principal, kind, scopes, client_id},
drafts {building, awaiting_evidence}, reconciliation {tracked,
never_reconciled, behind}, backup {last_at, through_seq, stale}, the
prompts, and needs_attention (the twelve most urgent items, problems first,
with every item counted by kind), beside next_steps now in the envelope's
shape (tool or prompt, why, required; attention problems are required). A
new book is told to run the onboard prompt first, then to record the
company's facts and set up the chart; an active one is offered a draft
entry. The tool carries _meta anthropic/alwaysLoad, so a client that defers
tools loads it up front. The size fit shortens attention items and waiting
drafts after the convention summaries and before the lists, as before.

agent {model, reasoning_effort, harness} is accepted and written to the
call's access record (the access log shows it as agent), self-reported and
never checked, and used for nothing else: not in the answer, not in any
decision. Who asked is the request's alone: it is cleared when the request
ends, so a later resource read on the same thread cannot see it.

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 4236f03744 feat(store): a record's source can be corrected without touching its words (P5)
Accounting reason: a convention, a decision or an open item carries who
decided it, when and on what authority. When that is recorded wrongly the
honest fix is to say so on the record, not to restate the policy: a policy
revision bumps the convention's revision and reads as a change of the rule,
and a new decision supersedes the old one. A source correction changes only
the authority and says why, so the audit trail shows the words were never
altered.

New event types convention.source_revised, decision.source_revised and
open_item.source_revised {id, source, reason} under the journal feature
source_revisions: an older version would refuse the types, or show the old
source as the record's authority, so it stops at the declaration instead
(rules.md B-27) and books that have not had the owner's upgrade refuse the
write with format_upgrade_pending, journaling nothing. Replay sets the
source and nothing else (the text, the revision and the journal line stay);
the projection updates the rows' existing source columns, so no schema
changed. A correction must be one: other words, the same source, no reason
or an unknown record is refused.

books.set_convention takes reason (the text exactly as it stands),
books.record_decision and books.raise_item take revises with reason. Without
reason the old refusal stands and now says how to correct only the source.

8.0.6: the hand-written lines of the three shapes in
books_written_under_older_rules_still_open; fixture old-books/p5_before,
written by b97234ac (a revised convention, two decisions, two open items, a
draft) through old-books-writer/src/bin/p5_before.rs, opens to that
version's figures, so no figure moved; books_p2_served_cut_over_whole
refuses the correction before consent and takes it after; the fuzzer and the
viewer's journal know the types. The live books refuse the new write until
the owner gives the go-ahead; merging does not need it.

Tests: a_source_only_revision_is_journaled,
a_source_revision_must_change_only_the_source,
source_revisions_wait_for_the_upgrade, source_revisions_is_its_own_feature.

swaitsandClaude Fable 5.1 6a66a2855b feat(drafts): the drafts tools, the preview digest on every confirm, the digest tool (P4)
Accounting reason: a confirm must act on the thing that was previewed.
Every tool with confirmed (post_entry, reverse_entry, run_schedules,
dispose_asset, reconcile, close_period, create_invoice, create_bill,
write_off_invoice, purge_tin, consolidate_duplicates, and the S6
settlement tools receive_payment and pay_bill, which gain confirmed and
preview on a clone of the ledger) returns preview (SHA-256 of the
canonical preview) and refuses a confirm whose preview is missing or
stale (stale_preview, before anything is written). A draft's digest is
its own state and the settings seq; an operation's is the tool, its
arguments as sent, the settings seq and the journal head seq, so another
session's write forces a re-preview (D-50).

New tools books.list_drafts, books.set_draft_state, books.discard_draft,
books.preview_entry; reports carry as_of_status (drafts open on or before
their end, unreconciled accounts, settings problems) and take strict; the
CPA package is refused while a draft dated in it is open unless
allow_open_drafts gives a reason, journaled as a decision;
books.digest takes since_seq (what was posted since a journal line,
backdated entries included: defect 6) and lists zero_net_accounts,
drafts_by_state and the reconciliation split. Needs attention gains
'draft awaiting receipt' beside 'draft not posted'; the drafts handbook
is rewritten. Every over-the-wire harness confirms the way an agent does.

Docs: mcp-interface, rules B-43, parity, testing (with the For-P12
paragraph), architecture, and the unit's As-built block.

Tests: drafts.rs (a_draft_waits_for_its_receipt_and_posts,
the_gate_moved_and_the_mcp_error_is_unchanged,
a_reversal_needs_no_receipt_of_its_own, discard_unblocks_the_close_over_the_wire,
report_warns_on_draft_before_as_of, cpa_package_refuses_open_draft,
stale_preview_refused, every_confirm_tool_takes_a_preview,
digest_since_seq_is_posting_time, legacy_reversed_replays_identically,
gui_and_server_gate_agree), attention_parity.rs, format_upgrade.rs.

swaitsandClaude Fable 5.1 7299cf90f2 feat(evidence): one function decides whether an entry needs evidence (P4)
Accounting reason: the receipt rule (Pub. 583, Rev. Proc. 98-25: the
books must be demonstrably supported by the records) was decided in
three places that could disagree: the server's post, the digest, and a
string match on a journal-event origin in the viewer. ledger_core::
evidence::requirement is now the one decision: Required (with why) or
Exempt (with the source). A reversal needs no receipt of its own (its
evidence is its original's, D-47, D-12); neither do a closing entry, a
schedule month's or a depreciation run's posting, a disposal, a
document's entry, a payroll run or its remittance. The ledger learned
the two origins it could not see (a disposal, a remittance) from the
events that already name their entry, live and on replay. A split group
counts for a draft only: a posted entry's decision was made when it
posted.

The policy moved with it (evidence::Policy; ReceiptPolicy in
ledger-config keeps the words and delegates). Store::post_entry_checked
refuses a covered draft with no receipt (StoreError::ReceiptRequired,
which the MCP maps to the unchanged receipt_required error);
Store::post_entry stays the primitive that commands and fixtures post
through, since ~176 call sites post hand entries with no receipt. The
viewer's missing_receipt calls requirement; its string match is gone.

swaitsandClaude Fable 5.1 28d46332e4 feat(store): draft states and discards are journaled, posted_seq is kept (P4)
Accounting reason: a draft that waits on its receipt, and one thrown
away, are facts about the books' working papers that must survive a
restart and replay identically, or a discarded draft would come back and
hold its period open. entry.draft_state_set and entry.draft_discarded are
drafts_v2's (an older version stops at the declaration instead of
misreading them); no figure moves. Schema 19 (taken at merge as the next
after the current last): entries.posted_seq, and a draft_states table
(drafts are not rows of entries, so the plan's entries.draft_state column
has nowhere to live). posted_seq is the journal line that posted each
entry (entry.posted, entry.reversed, the line that closed a period or
posted a schedule month), identical live and on replay.

8.0.6: a hand-written line of each new shape in
books_written_under_older_rules_still_open; fixture old-books/p4_before
written by 25b52580 (hand entries posted late, a reversal, a document, a
schedule month, a recurring draft, open drafts, a close) opens to the
same figures (serialized entries omit a building state, so no golden
moved); drafts_v2_is_its_own_feature; the fuzzer and GUI journal know the
types.

Tests: draft_states_replay_and_project, drafts_v2_waits_for_the_upgrade,
posted_seq_is_the_posting_lines_seq, an_older_version_stops_at_the_draft_events.

swaitsandClaude Fable 5.1 bb1eb84200 refactor(reader): extract.rs moves into ledger-reader (U0d)
D-61 (Q-9): the writer sheds the typesetter and the crate map is layered
again. The PDF/XLSX reader (extract.rs, plan P6) is now the plain library
crate ledger-reader, moved whole with git mv and no behavior change.
ledger-store depends on it instead of ledger-import, so the store no
longer builds Typst or the fonts; ledger-import re-exports it as
ledger_import::extract so gui, mcp, host and the fuzz targets compile
unchanged, and still never depends on the store. New crate carries only
the dependencies extract.rs imports (hayro, hayro-interpret, kurbo, zip,
quick-xml, thiserror); fuzz/Cargo.lock gains the new package.

swaitsandClaude Fable 5.1 3a1f4fd4eb test(store): a write-off whose notice is another entry's receipt is refused before posting
The defect found merging S7 and P6: under P6's dedup the notice's
bytes resolve to the record already on file, and the one-receipt-one-
entry rule refused it only after the write-off had journaled its
entry. The store now checks the deduplicated record before the journal
line (`6c26160e`'s companion fix in `write_off_invoice`); this test
pins it: the refusal names the record and its entry, the head and the
journal are unchanged, no entry posts, the invoice stays open, and the
books verify. Also formats the B-27 test `ci-fixes` brought in.

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 76285434cb fix(fuzz): fuzz_settings_replay builds again; a B-27 check for an unknown convention kind
The weekly run's fuzz_settings_replay job failed to build since P3 gave
each projection schema its own file: the target still named
ledger_store::DB_FILE, which became db_file(). The fuzz crate is outside
the workspace, so just check never compiled it; every target builds
again (cargo fuzz build, 2026-10-29).

The same run's fuzz_store_replay crash (the writer refusing a journal
with an unknown convention kind as newer while the viewer said something
else) is not reproduced yet: the hand-made case, kept here as
an_unknown_convention_kind_is_newer_for_the_writer_and_the_viewer_alike,
passes, so the divergence needs the fuzzer's exact journal, which the
weekly job now keeps as an artifact.

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).

swaits d1fb512e4b feat(arap): record an invoice's sends as invoice.sent (P4b S5)
The books never send invoices (A-4), but they must remember that one
went out: who sent it, how, to whom, when, whether it was the original
or a reminder, and the channel's own reference. That record is a fact
of the document's life, not a figure: a send moves no money, so it is
one journal line (`invoice.sent`) and no entry, and every derived
figure (outstanding, aging, DocState) is exactly as it was.

`Ledger::mark_sent` refuses a send on a void invoice (it should never
have reached the customer), a send dated before the invoice, no
recipients, and any recipient, reference or note that would put a full
TIN or control characters into the journal. Open, partial, paid and
written-off invoices can be sent (a copy for the customer's records, a
reminder).

The event is `documents_v2`'s (D-52): an older version refuses the
type rather than dropping the record. Replay restores it and the
projection keeps it in schema 16's `invoice_sends` table, so live,
replay and the viewer agree. The new old-books fixture `p4_s5_before`
was written by eeee9658 and opens to the same figures; a hand-written
send in `books_written_under_older_rules_still_open` proves an older
journal with the new line still opens.

Tests: mark_sent_waits_for_documents_v2, sends_replay_and_project,
a_send_changes_no_figure, mark_sent_on_void_refused, Op::MarkSent in
status_is_a_function_of_journal_and_date,

swaits 78a2385440 feat(store): journal settlements and replay their lines (P4b S6)
Store::settle now journals a settlement once, line for line, and one
payment event per application, so replay rebuilds the same tags and the
projection sees the same entry. A single legacy-shaped payment is still
journaled byte for byte; more than one document, a discount or a fee
needs documents_v2, and a payment accepted only because an earlier one
was reversed still needs document_standing.

Each event names the control line it tags (line) and, when it took one,
its discount and discount line; the fee is on the first application's
event with its line. Replay tags exactly those lines and leaves a line it
cannot match untagged, which books.control_check lists; a legacy event
without line keeps the first-untagged-control-line rule.

Tests: a_settlement_names_its_lines_and_replays (two invoices, a discount
and a fee; event indices match the plan; replay equals live),
settlement_waits_for_documents_v2 (refused with the feature remedy and no
journal line, accepted after the upgrade), and

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).
2026-10-27 12:44:45 -06:00
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.
2026-10-27 12:23:32 -06:00
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).

swaits 98320b3018 test(store): S4.2's shapes open old books and wait for consent (P4b S4.2)
The 8.0.6 checklist for this slice, which adds fields on party.updated
(an email and two default terms) and the invoicing settings it guards:

1. books_written_under_older_rules_still_open now hand-writes a party's
   email and terms and an invoicing setting through JournalWriter, and the
   books still open, verify and replay them.
2. A new old-books fixture, p4_s42_settings_parties, was written by the
   version before this slice (1bfce915, through the old-books-writer
   harness) with a party, a vendor, two posted entries and three settings,
   and its expected.json from that version's code. This version opens it,
   verifies it and reports its figures identically.
3. books_p2_served_cut_over_whole gains a refused invoicing setting before
   the go-ahead; the same call succeeds after it.
4. documents_v2_is_its_own_feature: books that declared every earlier
   feature stop at its declaration as newer, wait for the upgrade, and
   name exactly it in the upgrade.
No figure moves (item 5): settings and party facts enter no report.

Merge does not need the owner's go-ahead; the live books refuse the new
party and setting writes with the upgrade remedy until he gives it.
2026-10-27 03:44:24 -06:00
swaits 962b52c991 refactor(settings): the slice's contracts and notes (P4b S4.2)
invoicing.first_number's refusal (LedgerError::FirstNumberLocked) lands
as the contract the store's check raises once invoices carry numbers
(S4.3): a series that has begun is never renumbered (B-40, A-2).

Also: the settings invariants name the number prefix's bound, update_party's
doc says which facts wait for documents_v2, and the email check no longer
reads as a single-arm match. Terms is S4.1's as it landed; this slice no
longer carries a copy.
2026-10-27 03:44:24 -06:00
swaits 02cb7f0254 feat(parties): an email and default terms per side (P4b S4.2)
A customer's email is copied onto an invoice's bill-to snapshot at issue,
and a party's default terms (one as our customer, one as our vendor) are
the fallback a document's due date takes when the document itself names
none (A-13, rules.md B-39). Both are journaled as party.updated facts and
guarded by documents_v2: in books that have not declared it the write is
refused with the upgrade remedy and journaling nothing, and replay gives
the same directory back.

An email must be one plain address: one @, no spaces, no full TIN (the
party text rule already refuses nine digits). Terms are typed and already
canonical, so there is no second spelling to check. A party.updated naming
a field this version does not know is now NewerJournal, never corrupt
(B-27): an older version must say update, not damage; a known field with a
malformed value is still corrupt.
2026-10-27 03:44:24 -06:00
swaits 1fa77cff02 feat(settings): invoicing, bills and contact settings (P4b S4.2)
Eleven settings the invoice and bill workflow reads: the number prefix and
first number, default terms, payment methods with their bank details and
QR links, a footer, the unsent and reminder day counts, the bill reminder
and discount-warning day counts, and the company's email and website that
the seller snapshot prints.

Three new kinds keep them exact: a count is a positive whole number, terms
are canonicalized through Terms so "net 30" is stored once as "Net 30"
(B-39), and a payment method list admits at most eight methods whose lines
are at most 120 characters. A routing number is nine digits, so an ach or
wire method's bank-detail lines are the one text exempt from the full-TIN
check (A-3); every other text in a method is scanned.

The keys need the documents_v2 feature (D-52): an older version doesn't
know them, and the settings replay refuses an unknown key as newer. The
constant, the known-features entry and the gate test land with this slice
(its 8.0.6 work); S4.3 adds the document write call sites and must not
redeclare them.

A settings file now exports the [invoicing] and [bills] tables, a payment
method as an inline table (never a [[payment_methods]] section that would
land outside its table), and imports them back to the same values. The
unknown-key test uses fax instead of website, which is now a setting.
2026-10-27 03:44:24 -06:00
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.

swaits 9e67c8819d fix(tin): mask and refuse a comma-separated TIN (P7)
The scanner now finds a comma-grouped TIN, so the two places that hand
raw text out or let it in must follow: the access log's digest and its
64-character client texts masked hyphens but not commas, and a filed
file's printed-shape check refused 123-45-6789 but let 123,45,6789 in.

The access log uses the shared redactor, so it inherits the fix; the
filing scan keeps its own deliberately narrow shapes (a bank export's
routing numbers and amounts must still be filed, B-26) and gains the
comma renderings of an SSN's 3-2-4 and an EIN's 2-7. A comma-grouped
amount is still no TIN and still files.

No book, journal line or figure changes.

swaitsandClaude Opus 5.5 ebb5fcb46f refactor!: files only by handle: uploads in, downloads out (D-46)
check / check (push) Canceled after 0s
The owner (2026-10-23, via the question tool): "Uploads only"; and
before it: "What we would DEFINITELY want to avoid is passing a bunch
of BLOBs through AI context windows. That's just a pure waste." No file
passes through an agent's context, in either direction.

In: the inline arguments are gone with the 256 KiB limit (INLINE_MAX,
take_file's inline branch): content_base64 and its sha256 on
books.attach_receipt and books.file_document, w9_content_base64 and
w9_sha256 on books.set_w9, csv_text on the two CSV imports. A file comes
only by books.begin_upload and `wanderbooks upload`, named by its
upload_id; existing_attachment_id still names bytes stored already. The
five filing tools deny unknown fields, and any inline argument to any
tool is refused before it runs as an unknown argument pointing to
books.begin_upload (access log: refused inline_file).

Out: books.export (every format), books.asset_labels and
books.get_receipt view bytes hand the file over (HandedFile: download
command and expiry, D-29), as the CPA package and the W-9 do. Resource
reads stay text. A token keeps up to 64 handed files (was 16). The
access log's digest no longer exempts file bytes.

Docs: handbook files-in-out and parties-and-tins, mcp-interface.md,
rules.md, receipt-store.md, parties-and-attachments.md, plan/served.md
(D-46; the inline decisions marked superseded), STATUS.md, testing.md
(D-46: tests migrated to uploads and downloads, rewritten, removed,
added).

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 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).

check / check (push) Canceled after 0s
A project is a class with facts (description, status, kind, party,
dates, links, notes) in one project.set event behind the format
feature projects. Four tools (books.add_project, update_project,
projects, project); documents and decisions link to projects; B-37:
on-spec costs are expensed as incurred, repayment is revenue, and the
unrecovered cost is never below zero (Kani). Viewer: a Projects list
and a project page with its figures, by month and by account. The
sidebar measures its footer instead of reserving a fixed 172 px.

check / check (push) Canceled after 0s
A schedule-convention setting, the two new tax categories, a disposal
before the in-service date and a depreciation catch-up each need their
feature now (tax_categories_gain_exempt, disposal_before_service,
depreciation_catch_up), so no write before consent leaves books P2 refuses
or misreads; replayed names are read with P2's TIN detector (B-28). The
cutover runs end to end through the real P2 and P3 binaries in a test.

swaitsandClaude Opus 5.5 6288ead747 P3 review: asset bases and the tax-basis K-1
Schema 13 is as shipped and the asset columns are schema 14 (shipped
migrations pinned by hash); the tax-basis K-1 leaves net income open (only
the return has it) and takes a contributed prepaid plan at its book amount
as its section 723 basis; a disposal of contributed property names its
704(c) gain or loss; aliases compare by meaning; fixture amounts made up.

check / check (push) Canceled after 0s
Book value is cost less what the books posted; the schedule's figure is
apart. An asset's acquired date comes from its entry. Contributed
property keeps its section 723 carryover basis apart from its depreciable
basis (the lower of value and adjusted basis), with its 704(c) built-in
gain and method. The K-1 worksheet reports tax-basis capital (Form 1065
Item L) beside the book figures, leaving open what only the CPA knows.

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.

The final month takes what the months before leave, spread over its days;
a disposed asset stops on its disposal day. A skipped month is caught up
in the month the run is made; a reversed run un-posts its month. New
schedules spread by day; equal-months schedules must start on the 1st.
Amounts round to the currency's own minor unit. Kani and Lean proofs; an

Each party's part of an entry is signed as its own account would show it,
with a direction and its cash and in-kind amounts; a reversal is its
original negated. Totals on a cash or all basis: for a member, all equals
the members' equity statement and cash the K-1's cash. Money is cash,
cards and the financing accounts, and a liability credit never pays its
own creditor (creditor_of), so accruals and declared distributions count
once. tin_last4 from the TIN or W-9 facts.

swaitsandClaude Opus 5.5 cbb7d54463 P2 slice 9: put the old copies aside after an adoption
`wanderbooks books put-aside ID DATA-DIR [--vault DIR --vault-key FILE]
[PATH...]` moves the old copies of adopted books (their data folder, their
TIN vault and its key, their settings file, the git history around them,
old exports) whole into numbered folders of their own in the root's
legacy/, a list of where each came from written and synced first. Nothing
is deleted. Refused unless the books hold everything the old copy does,
byte for byte (journal, stored files, vault records, key; what adoption
left behind and records the books sealed anew are listed and go aside
too); while a wanderbooks process holds it open for writing; when its
head moved since the preview; for links, paths named twice, inside the
root or missing, a vault or key given as a plain path, and paths on
another disk. Renames never replace anything, and a move cut short puts
back what it moved. Three review rounds of data safety.

The plan records the cutover's answers (Q-3: move the old copies aside;
the backup repository and folder).

Also: `connect`'s "the books fernhill' agent token" reads properly, and
the restart tests wait for a copied program to be runnable (a child forked
by another test while the copy was written made it "text file busy").

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.
