The build seat runs merge-check as root, so every folder a test made was root's
data, which is never kept (§12), and 28 tests failed for that alone. A test's
folders now stand for an operator's: run as root, they are given to nobody before
they are judged. The root rule is unchanged.

The engine delivers before the controller half, and today's controller sends no
identities, users or taken. Keeping now starts only for an access whose folder has
users, or a declaration with identities; every other access is mounted when present
and refused when absent as on main, with nothing made, kept, held or judged. A
leftover whose walk could not run says why, not always that its disk is away.
A name read that timed out gave an empty name, which differed from the recorded one
and so reset the record: a folder kept while empty asked again, a warranted one was
walked again. An unnamed filesystem now leaves the folder exactly as it is, the
access is said not known for that look, and it resumes once it is named.
NFS and FUSE report a zero f_fsid, so another export or another FUSE mount at the
same point was named alike and kept without a warrant; xfs's f_fsid follows the
device number. A filesystem is now named by its UUID (its device matched in
/dev/disk/by-uuid), else a nonzero f_fsid, else mountinfo's source; one that cannot
be named is never kept or taken. Entries left on a filesystem not back within 30 days
are forgotten, said once, and the naming read is shared per mount.
An ext4 or xfs library mounted by UUID can come back from a reboot as another device
(/dev/sdb1 as /dev/sdc1); naming the filesystem by mountinfo's source read that as a
move, stripped the warranted library's entries and asked for a new Approve. A
filesystem is now named by statfs's f_fsid (from the UUID, or the ZFS dataset), its
type and its mount point. Entries left on the filesystem a folder is on now are
merged back or held, never walked away, and a TakenOn naming a mount point is not
taken.
A folder kept because it was empty, then covered by its disk, was said as unhealthy
leftover entries for ever: its entries sit on a hidden empty folder and grant nothing,
so they are now forgotten, and only entries walked onto data under a warrant are kept
to be taken out. A warrant and a kept folder now name their filesystem by mount point,
source and type, so another pool at the same point is a move; records naming a mount
point are read as its name. A record with no access ids is said under a path-free name.
A container was still created over an unmounted mount point, so its writes landed on
the filesystem below; a folder moved to another disk was kept on the old warrant; and
entries left by a drop or a move that could not run lived only in a log line. Every
container mounting an access whose disk is away now waits, the warrant holds only for
the filesystem it was carried out on (the wait names the new one, path-free), entries
left on a filesystem are recorded per mount and taken out when it is back, and every
leftover is said as unhealthy until it is. A hung stat is shared per path, and a
widened mask takes from other entries only the bits it adds.
A walk run while a dataset was unmounted wrote onto root's empty mount point, or
"dropped" entries from it and forgot the ones on the data; a folder kept while empty
below an unnamed mount was then swept whole once the disk mounted, with no warrant.
Every walk is now judged as an apply is, a changed mount judges the folder afresh, and
systemd .mount units and mounts seen are read for the first-sight rule. Widening a
mask caps the entries it limited, so the owning group gains nothing. The watch lets
go of removed folders, re-arms on lost notice, reads users under its lock and ends
with its context. A drop that cannot read an ACL is counted, a broken folder's words
carry no path, a grant's group that could not be left is tried again, and a folder's
stat is bounded.
A module's containers ran as whatever their image chose and shared folders were
made writable by putting accounts in the folder's group (ADR 0312), which ADR 0325
supersedes. The engine now makes each declared module identity as a system account
with the controller's numbers, runs a container declaring `identity` as it, and keeps
each placed shared folder usable through one POSIX ACL entry per user, set through
the kernel's xattrs on descriptors it opened itself. A folder holding data is kept
only after the operator's warrant (the take act); a missing folder is made where its
data lives and waits where its disk is not; root's data is never kept. A watch and a
bounded sweep put back what an app narrows. The group grant is removed, and what it
put an account in is taken back.
Reuses the descriptor walks, the create act, the missing-path wait and the warrant-
backed act message from the paused issue 567 branch.
