Store::verify compares the whole SQLite projection, every table row for
row, against a fresh projection of the journal; verify_and_heal rebuilds a
drifted database (keeping the old file) at every server start and via the
new books.verify tool, which also re-hashes every blob. The GUI checks the
server's database read-only and every stored file, and shows the result.
rebuild() also drops stale WAL/SHM files.
site/: the wanderbooks website (just site, just publish). install.sh:
OS detection (Windows points to WSL2), C compiler and git checks,
WANDERBOOKS_REPO. Windows: no directory fsync off Unix; .exe-aware lookup.
Repo justfile: check, build, install, demo, site.

egui/wgpu app for owners and their accountant: Overview, Cash, Profit,
Transactions (with rendered receipts and journal history), Reports
(statements with interval columns, comparisons, drill-down), Accounts,
Documents, Company, Journal; Ctrl+K palette; back/forward; light/dark.
Follows the journal live (~30 ms from write to screen). --demo opens a
deterministic demo company, also used for screenshot tests.
Engine: ledger-store Snapshot (read-only, incremental, tolerant of a
half-written tail); ledger-core analysis (intervals, balance series,
P&L by interval, cash flows); ledger-config extracted from ledger-mcp
with the full company profile and cash_accounts.

Vendors carry form_1099 (NEC/MISC) and tin_on_file (never the TIN).
Entries carry the vendor they paid; bills, bill payments, and reversals
are tagged automatically. books.vendor_1099 counts cash paid per vendor
per calendar year (card payments excluded) against $600 through 2025 and
$2,000 from 2026, or an override, and flags missing W-9s. Four new tools
(64), two journal events, schema v7. Docs: finished R-FUTURE work is no
longer listed as future.

Amortization schedules spread a prepaid expense or deferred revenue over
the months it covers, to the cent, posting on month ends; runs preview
first, are idempotent, honor closed periods, and are exempt from the
receipt policy like depreciation. Recurring entries generate drafts only,
never posts. Six new tools (59 total); four new journal events, replayed
and checked.

Every business has owners, and how owners put money in and take it out
depends on what the business is. wanderbooks now knows the four common
US shapes:
- books.chart_template {entity_type, owners}: a starter chart for a sole
proprietorship (owner's capital and draws), partnership or
multi-member LLC (capital and distributions per partner, guaranteed
payments), S corporation (stock, APIC, shareholder distributions,
officer compensation, retained earnings) or C corporation (dividends,
income tax expense), plus common income and expense accounts with
tax categories, and the wanderbooks.toml settings that go with it
(tax form, members with equal-share placeholders that sum to exactly
100, close target). A proposal for the agent to review with the human.
- Closing: CloseTo is now RetainedEarnings { sweep }, Account { into,
sweep } (a sole proprietor's capital) or Members([MemberClose { capital,
share, distributions }]). Sweeps zero owner-pay equity accounts into
their target at close: draws into owner's capital, dividends or
distributions into retained earnings, each partner's distributions
into their own capital. Validation (equity, distinct, shares sum to 1)
runs in the pre-close preview, before anything is journaled. The
journal records the target; journals with no target or the old
"retained_earnings" string still replay.
- Members' equity: a partner's distributions account is part of their
capital; its activity reports as distributions.
- Config: members' distribution_account; [books] close_into and
close_sweep for single-owner businesses (rejected alongside members).
The cash flow names members on their distribution accounts too.
Tests: a sole proprietor (net 2,000 and 500 of draws into capital: 6,500,
the cash); a corporation (dividends 300 into retained earnings: 600); a
partnership with distribution accounts (Bob 100 + 25 - 20 = 105, swept at
close, February begins there); bad sweep accounts; templates round-trip
through the chart parser, unique codes, equity per entity, every tax
category valid for the entity's return; stdio: template -> settings ->
import -> postings -> close with the exact closing lines.

The close zeroed every revenue and expense account's all-time movement,
so closing a period after later entries were posted swept those too:
close January in March and February's and March's income landed in
January's closing entry. The preview had the same bug and never showed
where the net went. Now:
- close_period_to(id, to) zeroes balances as of the period end; entries
dated later stay open for their own period. Periods must close in
order (LedgerError::CloseOutOfOrder): a later close has already swept
the earlier period.
- CloseTo::Members: for a partnership (multi-member LLC) the net goes to
each member's capital account by share, to the cent, the last member
absorbing rounding, which is what K-1 capital accounts track.
CloseTo::RetainedEarnings (3999) stays the default; close_period is
shorthand for it. books.close_period picks Members when
wanderbooks.toml lists members.
- The journal records the close target; replay re-derives the closing
entry and now compares every line with the journal, not just the id,
so a change to closing math can never silently rewrite history.
- The tool's preview is the real close run on a clone of the ledger
(Ledger now derives Clone), so preview and post can't disagree.
- Members' equity: closing entries into a capital account are income,
not contributions. Balance sheet for a partnership: capital accounts
(with allocated earnings), then only unallocated earnings —
"Undistributed earnings, prior years" if any, and this year's unclosed
net income (loss). periods::allocate is shared by the close and the
statement.
Tests: January closed after February is posted sweeps exactly Dr 4000
2,500 / Cr 6100 800 / Cr 3999 1,700 (mutation-checked: the old code gives
3,500/120/800/2,580); out-of-order close refused; a partnership close
splits 666.67 into 333.34/333.33 with no 3999, and the members' equity
statement reads correctly before and after; store replay of a members
close (reopen, rebuild, verify); partnership and corporate balance sheet
layouts; stdio close preview equals the posted lines.

Posted entries stay immutable (R-3), but their evidence can now change the
same way the ledger does: by appending events, never by editing or
deleting. New R-13a.
- books.unlink_receipt {attachment_id, reason} journals receipt.unlinked
and leaves the receipt filed, unlinked. The receipt policy holds: an
entry that requires a receipt can't lose its last one (structured
receipt_required error), so a replacement is attach-new, then
unlink-old. Drafts and reversals are exempt, as at posting.
- books.withdraw_attachment {attachment_id, reason} journals
attachment.withdrawn for an unlinked receipt or a filed document: hidden
from list_receipts (unless include_withdrawn), never linkable again. The
blob stays in the store, hash-verified and readable.
- link_receipt now refuses an already-linked or withdrawn attachment.
Before, re-linking silently moved a receipt off a posted entry,
bypassing the policy; evidence now leaves an entry only through a
recorded unlink. dispose_asset checks its receipt ids before posting
instead of after.
- Schema v5 adds attachments.withdrawn_at/withdrawn_reason; existing
stores migrate on open and replay rebuilds the projection.
Tests: store test (errors, reopen, rebuild, verify, journal history) and
an MCP stdio test (policy refusal, replace flow, withdraw, listings,
under-threshold unlink). Dry-run and live use on the Wanderland Labs books:
8 migrated .eml attachments swapped for their PDF renders, trial balance
unchanged.
