Split kernel::entry_flows into entry_movements and flows_of so the
reversal-mirror proof fits CI; prove runs the fast harnesses, prove-slow
the 8 slow ones (own job in scheduled CI), prove-all both. Laws in
verification.md renumbered 1-31 with a table of all 55 harnesses.
MCP docs checked against the 115 tools (about 60 fixes) with a test that
every tool is documented; rules.md cross-references fixed; bookspec
statuses and loader tightened; viewer notes wrap and accounts sort by
code; STATUS.md says P3 is built, cutover pending.

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.

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.

A distribution declared to a payable and then paid is financing when paid,
the declaration disclosed (ASC 230-10-45-15(a)); a disposal's depreciation
lines count as depreciation in the cash flow and the tax-basis K-1; an
as-of asset list says the status of that day. Seam tests tie the members'
statement, K-1, party totals, cash flow, 1099s, depreciation and the CPA
package together on three dates.

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.

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

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

`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").

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.

Owner, 2026-10-19: full color-scheme support for the viewer, the top
Neovim-style schemes, about twenty families each with a flyout of all its
variants, a light/dark/all filter, Ayu included, alphabetical, a whole row
to click.
- The sidebar's corner button (the light/dark toggle before) opens the
menu: the filter, then, alphabetically and all on screen at once (in
columns in a short window), Ayu, Catppuccin, Cyberdream, Dracula,
Everforest, GitHub, Gruvbox, Kanagawa, Material, Melange, Monokai Pro,
Night Owl, Nightfox, Nord, One Dark, Oxocarbon, Rosé Pine, Solarized,
Sonokai, Tokyo Night and Wanderbooks (the viewer's own Light and Dark):
80 schemes, each variant a row with a strip of its colors.
- Colors from each scheme's official source, checked value by value
(docs/color-schemes.md; the table names the sources).
- Every palette, the viewer's own included, keeps every text color
(figures, gains and losses, warnings, links, secondary and faint text)
at WCAG AA (4.5:1) on every ground it sits on, soft fills included; a
color that falls short keeps its hue and only changes lightness. Text,
secondary and faint text stay apart (each 1.2 times the next), gains,
losses and text and the charts' series shown together stay plainly
different (CIE76 ΔE 20).
- The scheme sets both egui styles and pins its mode, so the system
turning light or dark changes nothing (it made figures unreadable).
- Preferences now live in the platform's place for app settings
($XDG_CONFIG_HOME/wanderbooks-viewer on Linux), not eframe's default,
which was $XDG_DATA_HOME/wanderbooks: the data root's own place. The
old file is moved once.
- Tests: every page of thirteen painted in all 80 schemes, the same words
in the same places, each text readable on what was painted under it;
the menu's order, reach and whole-row clicks in a tall and a short
window; the system flip; preferences restored. Two review rounds.

The first scheduled run (2026-10-19) failed four ways: the viewer's
mutation job called the recipe retired in P2 slice 1 (owner, 2026-10-18:
no mutation runs on the GUI); the core and MCP runs were stopped at
GitHub's six hours; the import run missed six mutants.
- Every mutation recipe takes a shard (k/n, default all of it); the
workflow runs the core in 8 shards, the store in 4, the importers in 2,
the MCP server in 16, each its own job with a 350-minute limit.
- Test timeouts are three times each run's own baseline, never under the
recipe's old fixed value, so slower runners don't report false
timeouts.
- The mutants-gui job is gone.
- ledger-import: rule_marks_match_their_notes,
asset_register_xlsx_headings_and_totals_rule and
xlsx_missing_amounts_are_cells_only_on_ruled_rows catch the six
(the tax-basis rule marks, a heading's alignment, the totals row's
blank cells, and a blank amount cell only on ruled rows), each checked

ledger_store::root: one private folder for every book, found without the
environment (--root, else the root setup recorded in a file only this

password database). Every folder made 0700, files 0600; a root that is a
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.

The server and the viewer are libraries with run(prog, args), returning
Exit(code) instead of ending the process; ledger-mcp and ledger-gui are

wanderbooks dispatches dev-stdio and gui to them in-process; a mode must
come first and owns its flags. The gui feature (default) leaves the
viewer out of the server-only build, which just server-only builds,

member's share as typed: "50%" read from a settings file printed
0.50, the same share kept by the books as 0.5 printed 0.5. Shares now
print at least two places whatever their spelling.
Every company document now goes into the books (D-20, owner,
2026-10-17), and formation papers and plans print the company's EIN,
which the filing scan refused as a printed TIN. It now passes the
company's own EIN, as its settings hold it, printed 2-7, and nothing

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
