The audit's third tier: everything between this installer and a fresh machine
it has never met.
The one path that could cost a person their display: the interview probes
Secure Boot with mokutil, which install-packages had not installed yet, so on
a minimal base the MOK question silently never fired -- and install-hardware
still installed akmod-nvidia and blacklisted nouveau, arming a reboot into an
unloadable driver with its fallback disabled. The probe tools (pciutils,
mokutil, fwupd) now bootstrap beside gum, and install-hardware re-checks
Secure Boot for itself and refuses the driver rather than the display.
Secrets leave the checkout: the personal environment moves to
~/.config/panama/env at mode 600 by migration, and .bashrc sources it with a
permission check that quietly re-tightens drift. change-settings no longer
overwrites /etc/dnf/dnf.conf -- two performance keys are set additively, the
defaultyes=True that made every `dnf remove` treat Enter as yes is gone, and
a migration strips it from machines that already received it.
Package installation survives the world changing: the initial and desktop
lists run with --skip-unavailable and a report_missing pass that names what
was skipped (resolved through --whatprovides, so capability names like awk
do not cry wolf); the openh264, appstream and core-group extras go through
soft; RustDesk resolves its RPM for the machine's own architecture; and the
Claude Desktop repository script is fetched to a kept file and run, never
piped from the network into root.
The hardware predicates stop guessing: a wireless mouse's scope=Device
battery no longer turns a tower into a laptop, USB-PD-only machines read
their power state from the battery's own status instead of being permanently
"on AC", the lid falls back to logind's LidClosed where ACPI is silent, and
charge limits reach every pack of a two-battery machine in one authorization
-- with the reported percentage summed across packs.
And the parsers stop assuming this machine: snapper is read through
--machine-readable csv with named columns instead of a localized box-drawing
table, and reports whether snapshots are even possible so ext4 and
unconfigured-btrfs stop looking identical; fprintd is parsed under LC_ALL=C;
the hypridle drop-in resolves the binary it points at; the recorder's render
node became an "auto" token resolved at record time; update-grub writes the
config its firmware actually boots; the nvm prompt hook and the SSH tmux
takeover are guarded; hipblas and rocm-opencl move to an opt-in gpu-compute
category; and the two interactive python tools' libraries are declared.

The machine already had snapper running hourly on btrfs, so the tool was
never missing. What was missing is that snapper's only configuration
covered / -- and /home is a separate subvolume with no configuration at
all. Six hundred and forty-three snapshots existed and not one of them
contained a document. Anyone reaching for file history would have found
their system and none of their files.
/home now has a configuration on the same hourly timeline, with
deliberately conservative retention: Steam's 1.2 TB lives on that
subvolume and churns on every game update, so keeping five hourly and
seven daily bounds what those updates can pin.
Per volume, because on this machine "one is covered and the important
one is not" was the news, and a timeline opening on system snapshots
would have buried it. Inside a volume the timeline is the familiar view:
points in time, newest first, each openable as a folder tree to take a
file out of.
Restoring sets the current version aside as .before-restore-N rather
than overwriting it. A restore that destroys the thing you were about to
compare against is how someone loses the work they were trying to save.
Rollback is deliberately absent. snapper's rollback changes the btrfs
default subvolume, and this system's fstab pins subvol= explicitly,
which overrides it -- so a rollback would report success and change
nothing after a reboot. A recovery feature that silently does nothing is
worse than not having one, and making it work means editing fstab and
the bootloader, whose failure cannot be repaired from inside the
desktop.
Per-snapshot size is reported as not measured, because measuring it
needs btrfs quotas that cost performance on every write. Free space is
shown instead, which is the number that decides anything.
