docs/sidecar-audit-2026-07.md called this
one dead months ago
deliberately KEPT, because "no caller" turned out not to mean "dead":
POST activity/announce not orphaned — it is the missing PRODUCER for the
detached[] list GET activity/tasks already returns
and ActivityScreen already renders. an unbuilt
feature, not dead code, and finishing or dropping
it is a product decision.
GET agents/runs three days old. part of agent grounds, still being
built. "not yet consumed" is not "dead".
PUT/GET vault/unlock-key six days old, storage half of a feature whose
client half is unwritten. the vault is off limits.
DELETE integrations/google/connection caller exists but is deliberately
commented out of the tree. dormant on purpose.
vnc-manager's getSession is now orphaned too, but it is sidecar-internal and
was not in scope; noted rather than chased.

Re-applies to the mirror what f22c667 did for Xvnc, which I dropped by restoring vnc-manager from an
older commit. The bug is in the lifecycle, not the server, so it came straight back: the running mirror
lives in module state, a sidecar restart forgets it while the process keeps running, and waitForPort
accepted ANY listener on 5900 as proof of a healthy start.
It bit immediately. An Xvnc left over from the virtual-desktop experiment kept hold of 5900, so the
restarted sidecar reported a healthy mirror while the browser was being served the stale XFCE session
underneath it — which read as "the revert did not work".
reclaimPort frees the port before spawning (TERM, then KILL after two seconds) and waitForPort now also
fails when the process we spawned has exited.

Reverts the Xvnc virtual-desktop work (83bf746, f22c667). The separate desktop was the right answer to
"4K on the TV and 1080p remote", but it brought a chain of its own problems — a dock left stranded
below the bottom of the screen after every resize, because xfce4-panel does not follow a RandR change
reliably — and the owner would rather have one session that works than two that need supervision.
So: one GNOME session, mirrored, with the TV set to 1920x1080. That is under SCALE_ABOVE_WIDTH, so
x11vnc serves it 1:1 with no scaling, and both ends see the same 1920x1080 desktop.
resizeSession is now off on the client — a mirror reflects a physical screen and cannot be resized.
scaleViewport stays ON and is load-bearing: noVNC maps a click as
(clientX - canvasRect.left) / display._scale, and autoscale() is the only code that sets the canvas's
displayed size and _scale in the same call. Disabling it pins _scale at 1 while the canvas is displayed
at some other size, which doubled every pointer coordinate. That was my change and my bug.
Kept from the Xvnc detour, because all of it applies to the mirror too: the display is discovered by
socket ownership rather than assuming :0 (GDM gives :0 to its greeter), -noxdamage is gone, the clip to
the primary output stays, noVNC loads as one bundle, and showDotCursor covers the invisible pointer.

Closes the TODO item about orphaned/duplicated VNC servers across sidecar restarts. The diagnosis
there was correct and outlived the move off x11vnc, because the shape of the bug is in the lifecycle,
not the server: the running desktop lives in module state, a sidecar restart forgets it while the
process keeps running, and waitForPort accepted ANY listener on 5900 as proof of a healthy start.
The next start would then spawn a server that could not bind the port, see the ORPHAN listening, and
report success — leaving the platform convinced it had started a desktop the browser was not
looking at.
Two changes. reclaimPort frees the port before spawning: TERM whatever holds it, KILL after two
seconds. waitForPort now also fails when the process we spawned has exited, so a foreign listener
cannot be mistaken for our own.

The TV runs at 4K so it can play 4K video; a usable remote desktop wants about 1080p. One framebuffer
cannot be both, so mirroring meant every remote session was a scaled-down 4K desktop — dense to read
and expensive to encode. This gives remote its own display at 1920x1080 and leaves the TV alone.
Xvnc (TigerVNC) rather than x11vnc: it is the X server AND the VNC server in one process, so nothing
polls or scales — the server knows which rectangles changed and encodes them directly, where x11vnc
had to diff a framebuffer it did not own. It also implements RandR SetDesktopSize, so the client's
existing resizeSession makes the desktop resize itself to the browser panel. No scaling on either
side at any panel size, which removes the density problem rather than trading it for blur.
XFCE rather than GNOME, and NOT because it is lighter. Ubuntu's GNOME is managed by per-USER systemd
units — org.gnome.Shell@x11.service, gnome-session-manager@ubuntu.service and the whole
org.gnome.SettingsDaemon.* set all sit under user@<uid>.service, and gnome-session@.target is marked
RefuseManualStart. A second GNOME session for the SAME user collides with every one of them. That is
almost certainly what 106e5bd recorded as "a ghost logind session that broke lightdm login" — a
property of the session model, not something care avoids. XFCE has no such per-user units and
coexists with the TV session: same user, same home, same files, different shell.
The cookie goes in ~/.vnc/Xauthority, not ~/.Xauthority, which belongs to the TV session and is not
ours to write. Display is chosen by scanning for a free number from :2 up, checking the lock file as
well as the socket because a stale lock alone stops an X server starting. Teardown kills the session
before the server, since killing Xvnc first leaves XFCE's children reparented and running.
Verified end to end on a scratch display before committing: Xvnc listened, XFCE came up with xfwm4,
xfdesktop, xfce4-panel and xfsettingsd, RandR reported a 1920x1080 VNC-0 output, and the GNOME
session on the TV was untouched throughout.

A screen that is plugged in but switched off still reports "connected" to xrandr while contributing
nothing to the framebuffer — which is exactly the state this machine is now in, with the unused KVM
output disabled. Counting those made the mirror take the multi-output path and clip to the primary
when there was only one live screen; harmless here because the clip equalled the whole framebuffer,
but wrong, and it would have masked a real single-screen case.
Only an enabled output carries a WxH+X+Y geometry, so requiring that in the pattern is what tells
the two apart.

-noxdamage was set in 106e5bd, the commit that introduced the mirror. That message explains every
other flag it chose — -scale, -shared, -forever, -localhost — and says nothing about this one, and
no doc or TODO mentions it either. It looks defensive rather than diagnosed.
It is not free. Without the DAMAGE extension x11vnc is never told which rectangles changed, so it
polls the entire framebuffer over and over to discover it. Cost then scales with screen AREA,
continuously, instead of with what actually moved. On a 4K mirror that dominates: it is why the
remote desktop here felt slow next to a machine with half the hardware and a sixth of the pixels.
xdpyinfo on this server reports DAMAGE, MIT-SHM and XFIXES, so the optimisation is available and
was simply switched off.
Kept as a comment rather than deleted silently: if stale patches ever appear (some drivers do
under-report damage) putting it back is the fix, and the next person should know that is the trade
rather than rediscovering it.

X composes every attached output into one framebuffer, so with a 4K monitor at +0+0 and a 1080p TV
at +3840+0 the framebuffer is 5760x2160 and mirroring it whole sent BOTH screens side by side,
then halved them for being over the scale threshold. The remote desktop showed a squashed double-width
image with the second monitor hanging off the right — correct, and useless.
Clip to the primary output instead: 3840x2160+0+0 here, which then scales to a clean 1920x1080.
Only clips when a primary is actually marked AND more than one output is connected. With a single
output the framebuffer already IS that screen, so clipping would add a failure mode for no gain.
The scale decision now keys off what is really being served — the clip when there is one, the whole
framebuffer otherwise — instead of a framebuffer width that may span screens.
Never showed up under LightDM because only one output was ever live there.

The mirror hardcoded :0. That held under LightDM, which gave the user session :0. GDM does not —
it keeps :0 for its own greeter and starts the user's Xorg with -displayfd, letting the number be
picked at runtime; on this machine the session lands on :1. So after migrating to Ubuntu Desktop
the mirror failed on every attempt with "Can't open display :0", with a healthy session sitting
one number over.
Resolve by socket ownership: /tmp/.X11-unix/X<n> is owned by whoever runs that X server, so the
socket owned by us is the owner's session and anything else is the greeter's. Falls back to the
lowest socket (a root-run Xorg, as LightDM had) and finally to 0, so it is never worse than the
constant it replaces.
The display is now threaded through rather than read from a module constant, so getFramebufferWidth
measures the display actually being mirrored and both log lines name it.
Found while verifying the XFCE-to-GNOME migration on this machine — the session was up and x11 with
the cookie in the GDM path, and only the display number was wrong.

-scale 0.5 was hardcoded on the assumption that :0 is 4K. With no monitor
plugged in X falls back to something tiny — 800x480 on this box — and halving
that served an unreadable 400x240.
Read the framebuffer width from xrandr and scale only above 2560px. When the
width cannot be read, serve 1:1: too many pixels beats a thumbnail.

The desktop page has never worked on a fresh install. Two faults, both fatal.
The password could never be created. DesktopView fetches /desktop/vnc-password
before opening the WebSocket, but ensureVncPassword ran only from startSession,
which only the WebSocket triggers — so the endpoint answered "not configured",
the UI stopped, and the socket that would have provisioned it was never opened.
A new vnc:ensure-password sidecar command provisions it directly; the endpoint
asks for it instead of returning 500.
The rfbauth file could never be written either. ensureVncPassword shelled out to
tigervnc's `vncpasswd -f`, which is not installed — and, contrary to the comment
in setup-desktop.sh, is not in tigervnc-common, which ships only tigervncconfig.
The failure was swallowed because only a zero exit wrote the file, so x11vnc got
-rfbauth pointing at nothing. x11vnc writes that format itself with -storepasswd,
so the dependency is gone and a failure now throws.
Verified on the box: the endpoint returns a password, .vnc/{passwd,password} are
written 0600, and the sidecar reports mirroring :0 on 5900 with x11vnc using the
generated rfbauth file.

Officer is single-user: the server owner is the only account, created once by
/auth/bootstrap. Everything that existed to serve additional users was
unreachable, so it is gone rather than left looking like it does something.
Accounts: drop the invite / resend-invite / delete / list-users routes and the
Users settings screen, the inert /auth/signup handler, and the account
verification chain it fed (verify, resend-verification, VerifyScreen, the
UserInvite + VerifyAdmin + VerifyRegistration templates). /auth/verify-token
survives for password resets only, and now requires a reset-password token
rather than accepting any signed JWT.
Roles: drop the users.role column and the four-value USER_ROLES enum. The
permissions table granted every role identical methods, and every
role === 'Super Admin' check was permanently true. The JWT no longer carries a
role claim.
Sandbox: remove sidecar/sandbox.ts and its five call sites. bwrap was selected
only for non-Super-Admin users, so it never ran. It was also not a usable agent
jail as written — --share-net, the project root (with .env) bound read-only,
and runuser dropping to the server's own uid. Rebuilding it for agent
containment would be a different construction, and git history keeps this one.
getHomeDir keeps its DATA_PATH meaning; the new getOwnerHomeDir resolves the
owner's real login home, which is what terminals, chats and task runs use.

setup-desktop.sh now installs ubuntu-desktop + gdm3 + x11vnc and forces the
Xorg session (WaylandEnable=false) with auto-login — x11vnc can only mirror an
Xorg :0, not Wayland. vnc-manager.ts resolves the X authority from the GDM
per-session path (/run/user/<uid>/gdm/Xauthority) with a ~/.Xauthority fallback.
setup.sh fixes:
- desktop step gates on `dpkg -s ubuntu-desktop` (was the decommissioned
officer-vnc service, which never matched so setup-desktop re-ran every time)
- remove Pi (install, --list-models validation, verification check)
- export GOPATH before the cliamp build so `go install` lands where it's checked
even when Go was already present this run
- write PUBLIC_BUILD_ENV=production and quote all .env values
- guard the interactive .env block behind a TTY check so non-interactive runs
skip cleanly instead of aborting on read EOF under set -e
- restart systemd-logind only when a key actually changed
- sed prefix-strip instead of `tr -d` (which deletes characters, not a prefix)

- vnc-manager now runs x11vnc against :0 rather than vncserver on a fresh display,
so the browser shows the same session as the tv instead of a parallel one
- x11vnc reads :0's cookie from the logged-in user's own .Xauthority, so no root is
needed; mirroring only works while someone is logged in (the greeter's cookie
belongs to lightdm)
- -scale 0.5 halves the 4k framebuffer to 1080p for the stream, -shared -forever
keeps it up across browser disconnects, -localhost keeps it behind the ws bridge
- readiness is now the listening port, not exit code: x11vnc stays in the
foreground where vncserver daemonized and exited
- drops findFreeDisplay and per-email session tracking; there is exactly one :0
- the parallel desktops this replaces caused real breakage: a ghost logind session
that broke lightdm login, and a brave profile lock held on :2

replaces the single hardcoded systemd VNC service with a dynamic
sidecar that manages per-user VNC sessions on demand. any authenticated
user can now access their own desktop, not just Super Admin.
