fix(desktop): AppImage updates keep their filename - #25756
Every in-app update of the Linux AppImage breaks launchers that point at it. Release AppImages are named T3-Code-<version>-<arch>.AppImage. electron-updater replaces the installed file in place only when the file's name has no x.y.z version. Otherwise it writes the update under the new versioned name and deletes the old file. Symlinks, desktop entries and dock pins then point at nothing, and clicking the launcher does nothing.
Reproduced on main by running electron-updater 6.8.9's own AppImageUpdater.doInstall against the reporter's setup: an AppImage in ~/Applications, a t3-code.AppImage symlink and a desktop entry that launches it. After a stable update (0.0.36 → 0.0.37) and after a nightly update, the symlink dangled and launching through the desktop entry failed with ENOENT.
Change
createBuildConfig sets appImage.artifactName for builds that publish an update feed:
stable: T3-Code-<arch>.AppImage
nightly: T3-Code-Nightly-<arch>.AppImage
Without a version in the name, electron-updater replaces the file in place, so launchers keep working. Stable and nightly use different names so they can sit in the same folder without overwriting each other. Preview builds, the .deb and all other platforms keep their versioned names.
The AUR release.sh now looks up whichever AppImage name the release actually published, trying the new name first and then the versioned one. It writes that name into the PKGBUILD's _asset. The pinned PKGBUILDs and republishing an older tag keep working. The local source filename stays versioned, so makepkg caches don't collide.
An install that still has a versioned filename moves to the new name on its first update after this ships, which breaks its launcher one last time. Every update after that replaces the same file.
vp test run scripts/build-desktop-artifact.test.ts: 43/43 passed. The new test, names updatable AppImages without a version and apart per channel, fails on main with expected 'T3-Code-0.0.37-x86_64.AppImage' not to match /\d+\.\d+\.\d+/.
Updater transcript: electron-updater 6.8.9's own doInstall against a fake ~/Applications holding a symlink and a desktop entry.
versioned → versioned, stable and nightly: the launcher fails with ENOENT
version-free → version-free: the file is replaced in place and the launcher works

Real build: dist:desktop:linux x64 at 0.0.37 with the stable update feed produced T3-Code-x86_64.AppImage and T3-Code-0.0.37-amd64.deb. Its latest-linux.yml has url and path set to T3-Code-x86_64.AppImage. build-transcript.txt
AUR: release.sh run with a stubbed gh on synthetic release fixtures.
old stable and nightly tags resolve to their versioned assets
new stable and nightly tags resolve to the version-free assets
I checked by reading, not by running, that the release workflows (*.AppImage globs) and the marketing download links (-x86_64.AppImage / -arm64.AppImage suffix match) still match the new names.
This fix has no rendered UI, so there are no captures.

These tests reproduce #8944: updatable AppImages are named with their
version, so electron-updater writes each update under a new name and
deletes the installed file, leaving symlinks and desktop entries dangling.

electron-updater replaces an installed AppImage in place only when its
name has no x.y.z version. The AppImage was published as
T3-Code-<version>-<arch>.AppImage, so every update landed under a new
name and deleted the old file, breaking symlinks, desktop entries and
dock pins.
Builds that publish an update feed now name the AppImage
T3-Code-<arch>.AppImage (stable) or T3-Code-Nightly-<arch>.AppImage
(nightly). Preview builds and every other artifact keep the versioned
name. The AUR release script and PKGBUILDs download the new asset name
and keep a versioned local source name.
Fixes#8944
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Releases before the AppImage rename publish a versioned asset, so the
pinned PKGBUILDs and republishing an older tag kept pointing at a file
those releases never had. release.sh now picks whichever name the
release published and writes it into the PKGBUILD.

Macroscope's review found this PR approvable — Published Linux AppImages use stable, channel-specific filenames to preserve filenames across updates. AUR packaging supports both new and older asset names while retaining checksum validation; the change is limited to artifact naming and selection.
You can add or adjust custom eligibility rules. Learn more.
Linux builds now use versionless AppImage names for stable and nightly channels. The AUR release script checks those names before trying the versioned name, validates the SHA-256 digest, and writes the selected asset name into the package configuration.
Changes: Linux AppImage release

Summary
Configure and test AppImage names scripts/build-desktop-artifact.ts, scripts/build-desktop-artifact.test.ts
Published Linux builds use versionless names for stable and nightly AppImages. A test checks that the names differ and omit the version placeholder.
Resolve and package release assets packaging/aur/scripts/release.sh, packaging/aur/t3code-bin/PKGBUILD, packaging/aur/t3code-nightly-bin/PKGBUILD
The release script checks the selected asset name and then the versioned name for a valid SHA-256 digest. It writes the selected name to _asset, which both PKGBUILDs use in their download URLs.
pingdotgg/t3code#30909: This PR changes the same AUR release script and stable/nightly PKGBUILDs to select ARM64 and versioned or versionless AppImage assets.
Existing Linux AppImage users who launch the app through symlinks, scripts, or pins to a versioned filename will have that path break once, on their first update to the new filename. Later updates keep the path. Decide whether to ship a bridge release first or accept the one-time break before merging.

Explanation
Issue #8944 requires the launcher path used before an update to remain usable after the update. createBuildConfig now gives stable and nightly published AppImages version-free names, so later updates can replace the same file. The first update from an existing versioned filename still writes the new filename and removes the old file. The PR description confirms that this update breaks existing symlinks and desktop entries once. The added test checks artifact-name patterns. It does not test the versioned-to-version-free migration.
Resolution
Preserve the existing launcher path during migration from a versioned AppImage, or complete the migration through a versioned bridge release before this change reaches users. Add an automated regression test for the existing-install migration.

The current T3 main is 0ea3c0243fb5b3c07bb8c2bad01c1d3d0f5fde35. This replaces the older 268e5810... main SHA and behind counts in the prior handoff.

Normal exact-head Actions #41856083971 succeeded, including aur-release.test.ts 7/7 and Test 1,393 passed / 3 skipped. The intervening 84-commit main delta did not touch its five changed paths.

Versionless artifact PR fix(desktop): AppImage updates keep their filename #25756: OPEN / UNMERGED at 3550005771a2580723fc002367fcb7006392a056, 4 ahead / 1,586 behind current main (merge base d145077b4f7dc9e476bacf346e3f2c04cc141d6d). Its five changed paths are not touched by the intervening main delta, but its old-base CI is not current-main qualification.
Required order and composition: land/ship #30828 as a versioned bridge release before releasing #25756's versionless artifact names; do not combine both changes into the same release. #30909 and #25756 overlap in packaging/aur/scripts/release.sh and both stable/nightly PKGBUILDs. If #25756 lands first, #30909 must preserve its versionless selector; if #30909 lands first, #25756 must preserve ARM64 mappings and dual-name selection. Require one combined current-main diff and normal exact-head CI after the overlapping AUR hunks are reconciled.
Source custody remains with voltcrash (#30828/#30909) and Julius (#25756); Lane01 retains protected landing. Worker16 performed reviews only: no source edits, CI dispatch, package installation, AUR push, release, merge or deployment.
The automated pipeline stopped on this pull request and will not merge it:
the reviewers still had findings after 3 rounds (the work is on main...fix/issue-8944):
[major] scripts/build-desktop-artifact.ts:2932: Not fixed: existing versioned-name installations still lose their launcher path on the first update to these artifacts. electron-updater 6.8.9 executes the installer from the installed release, unlinks its versioned AppImage, and moves the download to the new basename. This is not worse than main, but it leaves the reported launcher failure unresolved for existing installations. The smallest remedy is release ordering: merge #30828, ship its bridge in versioned nightly and stable releases, then refresh and release this change. Shipping both changes together cannot protect the initiating old updater. Users skipping the bridge still experience one break.
Fails with: An existing Linux install has Applications/T3-Code-0.1.8-x86_64.AppImage and a launcher symlink targeting it. Updating to T3-Code-x86_64.AppImage deletes the symlink target. Executing the actual electron-updater 6.8.9 doInstall implementation with filesystem fixtures confirmed oldPathExists=false and launcherWorks=false. A versioned nightly transitioning to T3-Code-Nightly-x86_64.AppImage fails identically; subsequent version-free updates preserve the path.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Test preservation of an existing launcher path.
These assertions check the configured names, but they do not demonstrate that an update preserves the path of an existing versioned AppImage. Add a focused regression test at the lowest layer that can exercise that transition and fails on main.
As per path instructions, “proof requires the fewest failing tests on main that demonstrate the bug.”

When an installed AppImage has a versioned filename, its updater removes that path and installs the update under the new filename. Symlinks, scripts, and other launchers that use the old path can then fail. The app refreshes its own URL-handler entry, but not those other references.
Ship a migration before publishing these names. A bridge release also needs a plan for users who skip it.
