Neil f37d2fec97 fix(linux): land the reviewed Linux packaging stack on main (#18100)
* fix(linux): give the CLI one entrypoint by extracting the AppImage once

* refactor(linux): trim AppImage CLI registration seams

* test(cli): assert registration lock serialization

* fix(linux): fence AppImage terminal shim mounts

* fix(linux): accept extracted AppImage runtimes with APPDIR only

* docs(linux): make headless AppImage extraction runnable

* refactor(linux): import bundled launcher directly

* fix(linux): reclaim superseded AppImage payloads and packaged symlinks

Pruning removed 3215 of 3216 files from a superseded generation and always
stranded resources/app.asar, leaking ~105 MB per version update. Electron's
asar shim reports a *.asar file as a directory, so the recursive remove tried
to rmdir a real file and failed with ENOTEMPTY; the .catch(() => {}) hid it.
Reproduced end to end on Ubuntu 24.04: 519M -> 623M across one update, and
519M again once the payload is actually reclaimed.

removeExtractedAppImagePayload holds process.noAsar for the removal, counted
so overlapping removals cannot hand the shim back early, and the prune site
now warns with the path instead of swallowing the rejection. All three
removal sites use it -- staging cleanup and displaced roots leaked the same
way.

Also reclaim symlinks left by a packaged deb/rpm install, which the
extracted-cache-only rule turned into a hard conflict on a deb -> AppImage
migration, and name the remedy in the conflict error.

* fix(linux): bound the CLI registration lock wait

`retries: 1000` caps the attempt count, not elapsed time, so at up to 1s per
attempt an IPC-driven registration could hang ~16 minutes against a wedged
holder with no feedback.

A legitimate holder is bounded by the extraction timeout, so wait that plus
slack and then fail with a message naming the lock file, rather than hanging.
`maxRetryTime` is forwarded verbatim to the `retry` package by proper-lockfile.

* fix(linux): stop re-extracting the AppImage on inode metadata churn

The extracted-payload cache key hashed ctime alongside dev/ino/size/mtime.
ctime moves on any inode metadata write -- `chmod +x`, which every AppImage
user is told to run, plus `chown`, an ACL or SELinux relabel, and a backup
restore -- none of which alter a byte of the payload.

Measured on Ubuntu 24.04: `chmod +x` leaves dev, ino, size and mtime
identical and moves ctime alone, so the key changed and the next launch paid
a full ~519 MB re-extraction and a multi-second stall to rebuild a payload it
already had, then pruned the old generation.

Key on content identity instead. An in-place content change moves mtime and
almost always size; a replacement moves the inode. The existing
replace-in-place test still passes.

* fix(linux): stop CLI commands from falling through to Chromium startup

* refactor(cli): remove redundant command membership check

* test(cli): cover command-named project selectors

* fix(cli): redirect the open-url command before startup

* test(linux): cover AUR serve wrapper flags

* fix(linux): tighten CLI launch detection

* fix(linux): respect CLI flag value boundaries

* fix(linux): strip injected Chromium switches from CLI args

* fix(linux): report a missing display instead of dying in uv_close

* refactor(linux): read display locks without a preflight race

* fix(linux): preserve unverified external displays

* chore: format reliability gate manifest

* test(packaging): split runtime resource checks

* fix(linux): fail serve when no display is available

* fix(linux): do not treat a lockless X socket as a dead display

An X server writes its lock beside its socket and both survive a crash
(verified against Xvfb under SIGKILL), so a socket with no lock was never
left by a crashed server. It is an endpoint published from elsewhere: a
container bind-mounting only /tmp/.X11-unix, WSLg, or a foreign PID
namespace. Declaring those dead made the desktop gate exit(1) on displays
that work, with no workaround, and the serve gate refuse to start.

Liveness now splits by ownership. A foreign DISPLAY trusts a lockless
socket; Orca's own :99 does not, because removeStaleDisplayArtifacts
unlinks the lock before the socket and so manufactures that state itself --
adopting it would resurrect the orphan-socket bug and stop the cleanup from
self-healing. The stale-lock rejection is unchanged.

Also correct four doc statements this behaviour falsified.

* fix(linux): fail closed when a stale socket blocks the Xvfb rebind

Readiness only checked that /tmp/.X11-unix/X99 exists. A stale socket we
could not unlink still exists after our own Xvfb refused to bind, so Orca set
DISPLAY to a dead server and Chromium died in Ozone init.

Measured on Ubuntu 24.04 against the pre-fix build: with a leftover :99
socket and no lock, serve exits 139 (SIGSEGV), the socket inode is unchanged
before and after, and no lock is recreated -- it neither cleaned up nor
respawned. To a user that is a crash, not a misconfiguration.

This is reachable in the documented topology, where orca-xvfb.service has no
User= and runs as root while serve runs as User=orca: /tmp is sticky, so the
orca uid cannot unlink a root-owned socket, rmSync fails, and Xvfb exits with
the display already active.

Readiness now requires the display to actually be live -- our socket plus a
lock naming a running process -- so the same state reports an unusable
display and exits 1 with the existing diagnosis.

* fix(linux): recognise abstract X sockets and inherited Wayland fds

Two display setups this gate could not prove were refused outright, and on the
desktop path that is app.exit(1) with no workaround.

An X server may bind only the abstract namespace (`@/tmp/.X11-unix/X0`), which
leaves no filesystem socket to stat. Abstract addresses are kernel-owned and
vanish the moment the owner exits, so an entry in /proc/net/unix is proof of a
live server -- no lock file needed and no stale entry possible. Verified on
Ubuntu 24.04, where 139 such addresses were present.

WAYLAND_SOCKET is an already-connected fd handed over by the compositor, so
there is no path to stat and WAYLAND_DISPLAY may be unset entirely. Its
presence is the display.

Both are consulted only after the filesystem-socket check fails, so no
existing verdict changes.

* fix(linux): never treat Orca's own display number as a foreign endpoint

Recognising a lockless X socket as live is correct for an endpoint published
from elsewhere -- a container bind mount, WSLg -- because an X server writes
its lock beside its socket and both survive a crash. It is wrong for
VIRTUAL_DISPLAY_NUMBER, because Orca's own teardown unlinks the lock before
the socket and so manufactures that exact state.

The managed branch was already strict, but a caller that sets DISPLAY=:99
explicitly takes the foreign path and skipped it, accepting a dead display
left by Orca's own interrupted cleanup. Route the managed number through the
strict probe on both paths.

Found by an adversarial audit of the asymmetry introduced earlier in this
branch; the documented systemd topology is unaffected because its Xvfb writes
a real lock.

* test(linux): add a packaged-artifact contract for the CLI launch paths

* test(linux): avoid buffered serve readiness detection

* test(linux): signal AppImage serve owner directly

* test(linux): tolerate readiness timeout boundary

* test(linux): add startup margin to shutdown oracle

* ci(linux): give package contracts timeout headroom

* fix(ci): route all Linux packaging contract changes

* test(linux): poll shutdown readiness without tail leaks

* test(linux): bound shutdown cleanup grace

* test(linux): assert on CLI output, not the harness's own control lines

run-cli-case.sh echoes `RESULT status=N case=<name>`, and the two cases named
*-skills asserted `expectOutput: 'skills'`. That substring was satisfied by
the case name in the harness's own line, so 2 of 8 cases asserted nothing
about the command -- gutting `skills` entirely would still have gone green.

Control lines are now excluded before matching, and both cases assert the
rendered help header, which only real help output produces. Verified on an
Ubuntu 24.04 host: 8/8 still pass against a stack-tip AppImage.

Also register the gate in reliability-gates.jsonc, which #15085 added a CI
Docker gate without. Red/green is recorded from a stock release AppImage
failing 4 of 8, three of them at status 133 (SIGTRAP).

* fix(linux): require static AppImage runtimes (#17319)

* test(linux): reject a wrong-architecture native binary at packaging time

Cross-building the arm64 slice on an x64 host silently packed an x86-64
`pty.node` -- the rebuild logged "Forcing native rebuild for linux-arm64" and
shipped the host's binary anyway. Every gate here inspects symbol versions,
which are perfectly valid on the wrong architecture, so nothing noticed.

Observed on a Raspberry Pi 5: the packaged app loaded, then failed with
"Failed to load native module: pty.node", and the launch contract reported
3 of 8 cases crashed rather than naming the cause. Swapping in the aarch64
`pty.node` took the same build to 8/8.

Compare ELF `e_machine` against the slice being packaged and fail with the
offending path. Checked before the glibc pass, because a wrong-architecture
binary's symbol versions are valid but meaningless and would send the reader
down the wrong path.

Release CI builds arm64 on a native runner, so this guards local and future
cross-builds rather than a shipped artifact.

* test(linux): judge per-arch vendored binaries against their own path

The first CI run of the architecture gate failed the x64 package job on
`@parcel/watcher-linux-arm64-glibc/watcher.node`. That binary is arm64 on
purpose: the package ships every architecture and its loader picks the match,
so its presence in an x64 build is correct.

Judge a binary against the architecture its own path names, falling back to
the slice when the path names none. That keeps the case this gate exists for
-- `bin/linux-arm64-*/node-pty.node` holding an x86-64 binary, which is what
shipped to a Raspberry Pi 5 -- while letting multi-arch dependencies through.

Dry-run over the real dependency tree flags nothing for either target arch.

* fix(linux): move deb/rpm update installation outside Orca (#17318)

* fix(linux): complete deb/rpm package metadata

* fix(linux): preserve CLI link during package upgrades

* docs(linux): document local RPM build prerequisites

* fix(linux): move deb/rpm update installation outside Orca

* fix(updater): preserve Linux recovery across stale events

* fix(updater): fence stale downloaded events by active target

* fix(updater): preserve active Linux package recovery

* test(linux): keep workflow order assertion in scope

* test(updater): assert stale recovery stays silent

* fix(updater): preserve Linux package recovery after checks

* refactor(updater): keep Linux marker message with status

* fix(linux): describe the right manual update path for deb/rpm hosts

A remote host installed from .deb or .rpm now reports
manual-service-update-required, and the guidance told the operator to
"update through the service manager that starts this server" -- which is
correct for unsupported-headless-serve but wrong for a package install,
where nothing about the remedy involves the service manager.

Say both, keyed on how the host was installed.

* docs(linux): document orcad update restart safety

* docs(linux): scope restart census omissions

* docs(linux): use absolute service CLI launcher

* fix(serve): validate in-process serve options before startup (#17683)

* fix(linux): stop offering updates a distro-managed install cannot apply (#17918)

Closes #17702.

The resources/package-type marker is authoritative but never checked against
the host, so any repackager that unpacks Orca's .deb -- AUR, Nix, a container
rebuild -- inherits `deb` verbatim. Install feasibility was then computed
after a ~165 MB download, so those users got check -> download -> a card
promising an install command -> a dead end.

Validate the marker against the host: a deb/rpm marker with no matching
package manager in the trusted directories means a package manager owns this
install. This reuses the exact lists and resolver that
buildLinuxPackageInstallCommand already loops over, so a false positive is
impossible by construction -- any host flagged here would have failed with
no-package-manager after the download anyway. The gate only moves that
verdict earlier. Verified across Debian 12, Ubuntu 24.04, Arch, Fedora 40 and
openSUSE Leap: no false positive on a real deb host, correct on every
repackaging host.

The release is still reported, because the user does want to know 1.4.194
exists and to update through their distro; only the download path is closed.
`externallyManaged` is an additive optional field on the existing `available`
status, so older paired clients decode it unchanged. downloadUpdate() refuses
authoritatively, since main owns this verdict rather than the card, and
unwinds any pinned-build state first -- a Linux pinned jump resolves to
'release', and stranding isPinnedBuildActive would silently kill every
background check for the rest of the process.

Note the fix the issue suggests cannot work: electron-updater builds a
PacmanUpdater whose doDownloadUpdate looks for a .pacman asset Orca does not
publish, then dereferences undefined.
