The portable macOS job: five root tests spelled out `.local/share`
or compared a chosen root against its /tmp spelling where macOS keeps
/private/tmp. They use `platform_data_dir` and canonical paths now.

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.

`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").

The server backs each book up itself: a per-book git archive, pushed
fast-forward only to a git remote and to a folder, when the books open,
after a quiet spell, before they close and on request; every commit,
push and drill is a record in ops/backup.jsonl. Drills clone each
target and verify the chain, the blobs, the vault and the head, weekly
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
books.back_up_now for the agent.

One wanderbooks executable. The books are open while the viewer, an
agent session or a terminal holds them: a host process takes leases on
a socket, starts the server (the hidden mode `wanderbooks server`) with
a pipe on its input, and closes it 10 s after the last lease ends. No
background service. One host even in a race (run/host.lock).

ledger_store::root: one private folder for every book, found without the
environment (--root, else the root setup recorded in a file only this
account can write, else the platform default under the home from the
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.
wanderbooks setup makes the root and never prints where it is. Three
review rounds; mutation on the diff (docs/testing.md).
