From the race detector, staticcheck, a garbage-in battery over every safe route and a
headless pass through every tab on two machines. Fixed:
- docker inspect/health of a container that isn't there answered 500; now 404, and a
daemon that is down 503 (dockerErr, with a test).
- /api/virt/instances/{name} on a machine without Incus answered 502 "incus not found";
it now says Incus isn't ready, like its siblings.
- Deleting a ZFS snapshot with a bad name answered 500; a bad name is 400, a snapshot
that doesn't exist 404.
- The task list read a task's Running flag without the task's lock while the waiter
goroutine cleared it: a data race, now read under the lock.
- The Virtualization export config and run record were written in place; a crash
mid-write would have left a half file. Atomic now, like the config and state files.
- An unused function in kvm.go, one in incus/subnet.go, an unused field in files/move.go
and a capitalised error string, from staticcheck.

Found by walking every handler and the UI with odd inputs, then a battery of requests
against the live hub. Fixed:
- A save over the 8 MiB cap was cut short in place: the file was truncated, then the
first 8 MiB written, and the caller told 204. Now the body is read whole first and a
body over the cap is a 413 with the file untouched.
- A link to a file showed the link's own time; now the file's, so the row reads right
and the preview key follows the file.
- Reading a link to nothing answered 200 with an empty body (the open failed after the
headers in root mode); now a 404 that names the target.
- A play request with an unknown codec or size was answered by inspecting the file
first, so an audio-only file said "no video stream" instead of what was wrong; the
choice is checked before any work, and is a 400.
- A stream that ended in failure was handed back to the next identical request for ten
minutes; a failed one is now dropped and a fresh one made.
- A player that left while its stream was still finding a first segment made the loop
try the next recipe; it stops. A stream closed mid-start is not started again.
- Ending a root-mode ffmpeg could wait forever: the daemon cannot signal root's
processes, so the wait is bounded and the helper's own grace does the rest.
- A page going away (a phone closing the tab) releases its stream by a beacon, rather
than ten minutes later by the sweeper.
- The path box resolves like a shell — relative to the folder shown, . and .. applied,
trailing slashes dropped — in the tab and in the Move picker, with a test. A typed path
that is a file opens it; a remembered folder that is gone falls back to / once.
- A dropped folder arrived as a nameless empty file; it is refused with a word. The
upload toast counts what was actually uploaded.
- The viewer names a device, pipe or socket, and a dangling link, instead of calling
them binary files.

The package was named for its first job; it now also decides what a file is for the
Files tab (image, video, audio) and reads its streams, which the viewer will need. Inspect
is the richer probe — codec, profile, pixel format, size, frame rate, HDR transfer, the
audio beside it, container and duration — run as root through sudo when asked.

ServeContent seeks to the end for the size before it seeks to the range, which was
throwing away the stream Check had just opened.

The viewer hands a video or audio file to the browser untouched — container, codec and
all — and the browser plays what it can; when it can't, the viewer says so and offers the
download. What the server adds is the part a player needs: /api/files/read now goes
through http.ServeContent for a real file of known size, so Range requests (seeking) and
HEAD work, and a download can resume. The root backend's helper takes an offset for that,
and a Seeker opens the backend once, at the range asked for, instead of streaming from
the top. Audio files are a preview kind too: their cover art is the thumbnail.

The picker walks the machine like the tab does — back, forward, up, breadcrumbs, a path
box, a new folder — and "Move here" puts the file or folder in the folder being looked
at; it says why it can't when it can't (already here, into itself, a name clash). POST
/api/files/move is a rename when the two ends share a filesystem and otherwise a task:
on a NAS every move between datasets is a different filesystem, and a rename there is
EXDEV. The copy is built under a hidden temporary name beside its destination, renamed
into place once complete, and only then is the original removed, so a failure or a
cancel leaves the original as it was. Modes, times, symlinks and, as root, owners are kept.

A previews button on the Files tab turns the icon column into a 256 px thumbnail for
every image and video row, loaded as rows scroll near. internal/thumbs probes what the
machine can do rather than assuming it: ffmpeg and ffprobe, every /dev/dri/renderD*
opened and exercised, vainfo's decode profiles per node where it exists. A video goes to
the first GPU that lists its codec, with ffmpeg's own software fallback behind it and a
CPU retry behind that; images decode on the CPU, JPEGs at a reduced DCT size. Previews
are kept under <data dir>/thumbs/ keyed by path, size and mtime, with undecodable files
remembered too. Root mode makes them through the same root helper the file reads use.
Where ffmpeg is missing the tab offers to install it; where a render node exists but is
closed to the daemon's user, it offers a drop-in adding the group and a restart.

- hamlab install / uninstall (internal/setup): systemd or OpenRC, elevates through
sudo or doas, runs as the invoking user, sets or generates the password, names only
journal groups that exist, waits for /healthz, reports an active firewalld/ufw.
--purge and the data chown never touch a directory that isn't Ham Lab's alone.
- install.sh: curl-able bootstrap (arch detection, SHA256SUMS, offline beside the
binaries, noexec /tmp fallback). make release builds dist/ for amd64, arm64, arm
(ARMv6), 386, riscv64. Every build is CGO_ENABLED=0; the native one used to link glibc.
- internal/priv replaces every literal `sudo -n`: uid 0, sudo or doas.
- Updates acts on dnf, zypper, pacman and apk as well as apt; dnf shows installed versions.
- Services falls back to the plain systemctl table before systemd 246 and says so on
hosts without systemd. Disks falls back to /sys/block without lsblk.
- Listener binds with IP_FREEBIND, so a LAN address that isn't up at boot is no failure.
- Self-update: the new build must pass `check` against the live config, is put in
place by atomic rename, and the daemon re-execs itself (same under any supervisor).
- State and config writes are fsynced; a corrupt state.json is set aside, not fatal.
- Terminal shutdown no longer empties the saved list, so names come back after a
restart by design rather than by winning a race.
- Config default is ~/.config/hamlab; an existing ~/apps/hamlab is still found.
