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.

Pools are shown by where their bytes land (plain files on this disk, a ZFS pool inside one
file, a dataset…) rather than by driver name, which read as the NAS pool. A location can be
added as a plain-files pool at any folder on the machine, and removed while nothing uses it.
The driver order at Install is as it was; the labels say what each one really is.

spice-html5 opens a websocket per channel (main, display, inputs, cursor, playback), and
each one was making Ham Lab open a new console operation, which Incus refuses as already
connected. Now the first channel opens the operation and holds its control websocket; every
further channel is one more data websocket on the same operation, which Incus allows; the
operation is let go when the last channel closes. A stale operation from a previous Ham Lab
process is taken over with force.

- Library: an ISO shelf in virt/isos: upload (the Files uploader), fetch by URL with an
optional sha256, import a file from the machine by copying it in, rename, delete (refused
while attached), attach to a VM as a CD-ROM live or stopped with boot-first, eject, and
New VM from ISO: an empty VM with the ISO as first boot device, Secure Boot on or off.
- The VGA console: Ham Lab asks Incus for the VM's SPICE console over its unix socket and
bridges the display websocket to the browser, where spice-html5 (vendored from upstream
b372aab, LGPL, loaded on demand) draws it; Ctrl+Alt+Del, fit-to-window.
- Exports: every instance as a tarball in virt/exports/<name>/, kept to a count, as a cron
line in /etc/cron.d/hamlab-virt calling hamlab virt-export, settings and the last run
as files beside the data; Export now per instance or for all.
- Disks tab per instance: the root disk, attached ISOs with Eject, bind mounts in and out
(shift for containers, virtiofs for VMs).
- instance.* sensors (running, down, state, cpu, mem) and the VM-or-container-down alert
default, offered once to installs seeded before it existed.
- cloud-init: Use my SSH keys writes a cloud-config from the account's public keys.

Found on the first live test on grid: incus config set refused 'description' and the whole
limits save with it.

The tab reports one of four states for the selected machine (ready, repair, installable,
unavailable) from what it finds — /dev/kvm, the package manager's incus candidate, the
pool drivers the kernel has — and acts on that machine only. Install is one followed task:
packages, a pool whose backing file sits in Ham Lab's own virt/ folder (zfs pool on a file,
btrfs on a loop mount, or a plain dir), a bridge on a subnet picked clear of the machine's
routes and Docker's pools (never 10.x on a /8 LAN), the DOCKER-USER rules that keep
Docker's FORWARD drop off the bridge, the incus-admin group for Ham Lab's account, and a
restart. Instances list with live CPU and memory, create from the images: catalogue or a
local image (container or VM, limits, cloud-init), start/stop/restart/force-stop/rename/
delete, console and shell as terminal tabs, snapshots with Incus's own schedule and expiry,
limits editing. Images: local store, catalogue search and download (exported into the
library too), import a tarball or a VM disk from a path, publish an instance.
