fix(server): self-update moves the t3 command to the new runtime - #14875
A managed self-update commits the new server runtime but leaves the shell's t3 symlink on an older version. Later restarts must also preserve intentional user pins.
Reconcile owned launcher links through the existing ServiceLauncherClient after a fresh pending trial receives its committed acknowledgment. Update the configured install-bin link and the first existing PATH command when they point anywhere inside this T3 home's runtime versions. Replace each link atomically; preserve regular files and links belonging to another home, and log individual failures while continuing startup and the remaining candidates. Stored committed outcomes still reach readiness without moving links.
Local service installation now preserves T3CODE_INSTALL_BIN_DIR in both systemd and launchd definitions. Existing custom units need a local reinstall with that variable available, for example T3CODE_INSTALL_BIN_DIR=/custom/bin t3 service install. Remote updates do not rewrite service units. Once saved, the custom directory survives later CLI status checks and service reinstalls without the environment variable; an explicit replacement takes precedence.
Original three core suites: 21 cases → 25, retaining all 19 main-owned cases. Replaced the two original PR cases with five behavior cases; moved filesystem coverage from the CLI into the launcher client's existing suite. Added two custom-directory service installation cases. One additional cleanup-defect startup case proves readiness and remaining-candidate progress. Six final suites pass: 79 tests.
Fail-before: removing reconciliation breaks pending-trial startup; removing only the pending guard breaks stored-commit startup; both custom-directory installation cases fail before the environment fix. Both platform cases also fail before preserving the saved directory across ordinary CLI calls; cleanup-defect startup fails before the full-cause catch. Restored production bytes and reran the focused suites.
Server typecheck, scoped lint, formatting and whitespace checks pass. Lint retains one pre-existing unused-layer warning.
Real launcher child processes and IPC on isolated Linux files: main commits 1.0.0 → 2.0.0 while both links remain at 1.5.0; the rebuilt client moves both links to 2.0.0 after acknowledgment. A second actual launcher start preserves pins restored to 1.5.0. This is a minimal startup driver plus the actual launcher/client, not a full HTTP-server launch.
Behavior limits: a fresh commit moves any owned link, including one pinned to a version newer than the committed target, following the requested ownership rule. If the server dies between commit acknowledgment and relinking, a later restart preserves the stored outcome and does not retry; a subsequent update or local t3 update can reconcile the command.
Verification limits: no installed systemd/launchd service update or native macOS, Windows, Electron, iOS or Android verification. Linux/macOS launcher paths are covered by service tests; Windows shim behavior is unchanged. Two full adversarial review rounds completed with Claude Opus 5.5 and Codex GPT-6-Sol. Round 1 found the custom-directory retention and cleanup-defect issues; both were fixed and the second round found no blocking code issue. A dangling extra PATH symlink whose runtime was manually removed is outside discovery of the first existing command; configured install-bin links are checked directly.
Thanks to @JonasFocus for the original implementation and failure-isolation work in #14875. The takeover keeps the contributor commits, merges current main, and rebuilds the filesystem operation at the existing service boundary.

Once a launcher-managed update commits, the new server repoints the
installer's t3 symlink if it still points at the version it updated from.
A failed rewrite is logged and never rolls back the committed update.
Macroscope's review found this PR approvable — Committed self-updates now move owned t3 launcher symlinks to the new runtime and preserve custom installation-directory hints. Changes are bounded to existing runtime-linked commands, with atomic replacement and nonfatal error handling.
You can add or adjust custom eligibility rules. Learn more.
The service configuration now carries the install-bin directory into startup. After a matching update commit, the launcher client repoints eligible t3 symlinks to the target runtime.
Systemd and launchd units can include T3CODE_INSTALL_BIN_DIR. Install and status plans use the configured directory or retain the value from the existing unit. Tests cover persistence, replacement, and omission when unset.
Pass base directory to trial preparation apps/server/src/serverRuntimeStartup.ts, apps/server/src/serverRuntimeStartup.test.ts, apps/server/src/serverRuntimeStartup.autoPull.test.ts, apps/server/src/cloud/selfUpdate.test.ts
Startup passes baseDir to prepareTrial. Test mocks now define prepareTrial as a function.
Repoint launchers after commit apps/server/src/cloud/serviceLauncherClient.ts, apps/server/src/cloud/serviceLauncherClient.test.ts
After a matching committed reply, the client checks the configured install-bin launcher and the first existing PATH launcher. It repoints eligible symlinks into the pinned runtime versions directory. Tests cover successful updates, permission errors, and links or files that remain unchanged.

Suggested reviewers:juliusmarminge
Merge Risk: Low · up to d1b5b
Custom install-bin directory handling has two narrow edge cases: a replacement made from inside the service may not take effect, and a relative or whitespace-padded value may not be normalized. Neither affects the default update flow. Both are low-impact and can be fixed before or shortly after merge.

The description explains the problem, implementation, scope, verification results, and known limitations. It does not use the template headings exactly and does not state explicit maintainer approval, but it provides the required information and is mostly complete.
Full details: Linked Issues check
Explanation
Issue #14609 requires the installed t3 command to follow a successfully committed remote server update. prepareTrial now calls repointLaunchers only after a fresh pending trial receives its committed acknowledgment. The helper updates the configured install-bin link and the first existing PATH link when each link resolves inside this T3 home’s runtime versions. It replaces eligible links atomically, preserves regular files and foreign links, logs per-link failures, and continues with remaining candidates. Stored committed outcomes do not move links. Tests cover pending commits, stored outcomes, ownership, failure isolation, and readiness.
Full details: Out of Scope Changes check
Explanation
The service-unit changes preserve T3CODE_INSTALL_BIN_DIR, which is the configured link location used by the #14609 reconciliation. The launcher changes, service changes, and tests support link discovery, update handling, persistence of the configured directory, and failure isolation. No unrelated product behavior is demonstrated by the reviewed changes.

On the nitpick about moving this onto the launcher service: I'd rather leave it in cli/update.ts. It's a thin wrapper over repointLauncher, which already lives there and is shared with t3 update, and serviceLauncherClient only handles the trial handshake with the launcher process, not filesystem work. Happy to move it if maintainers prefer.
Use a deterministic filesystem failure instead of chmod(0555).
The server test command is vp test run, and the repository does not restrict it to non-root users. When that command runs as root, repointLauncher can create the temporary symlink and rename it into the 0555 directory. The install-bin launcher then points to 2.0.0, so the 1.0.0 assertion fails. Inject a failure for the launcher rewrite through the filesystem test layer instead of relying on directory permissions.

Thanks for the follow-up. The chmod test does assume a non-root user, but both the Ubuntu and Windows CI runners use normal user accounts, and the other ways to force a failure (like pre-creating the temp link name) would tie the test to how repointLauncher names its temp file. I'd rather keep the test about what a user would actually hit. Happy to change it if maintainers run the suite as root somewhere.
Hi! We are cleaning up open PRs, and this one does not say which model or harness was used to create it. If this change is really important, we recommend rebuilding the PR with a newer model and noting the model and harness in the PR description.
A middle way that keeps your guard against flipping a pinned t3 on every restart: move any link that points into this home's runtime/versions, but only in the start that commits a pending update. Later restarts, which just see the stored committed outcome, leave the link alone.
Taking over this one as maintainer for batch desktop-app-05. I will preserve your commits, update the host-process references for main, and exercise the actual startup handoff. I will also address the reported stale links that lag behind fromVersion while avoiding reconciliation on ordinary restarts. Custom service install-path discovery will be assessed against the existing local service-install scope.
@JonasFocus Thanks for the original launcher reconciliation and failure-isolation work. The takeover is published in 14699c5008, with the requested older-owned-link and fresh-commit-only behavior plus verified custom-directory retention. Two nonblocking limits are explicit in the body: a crash after durable commit but before relinking is not retried on stored-outcome starts; additional dangling PATH links whose old runtime was removed are skipped while finding the first existing command (the configured install-bin link is checked directly). These did not justify expanding the change into a recovery mechanism. Native service-manager handoff remains unverified on this Linux host; real child IPC and temporary service definitions are covered.
Only the launcher client knows whether this start committed a pending
trial, so prepareTrial now takes the base dir and moves owned t3
symlinks right after the commit. Startup no longer needs a trialPending
flag, and a stored outcome replayed on a later start cannot repoint.
The startup integration test and fixture refactor give way to a client
test covering both the commit and the replay.

Resolve and trim T3CODE_INSTALL_BIN_DIR before persisting it into the unit.
The installer in apps/server/src/cli/install.ts trims this variable and runs path.resolve on it, so the PATH hint does not depend on the working directory. make stores the raw value instead, and planForUnit writes it into the unit unchanged.
Take a relative value such as ./bin. The unit keeps ./bin. The service starts with WorkingDirectory=%h, so repointLaunchers looks for ./bin/t3 relative to the service's working directory, not the directory the user meant. The readLink call then returns NotFound, and the launcher is skipped with no warning. A whitespace-only value is truthy, so it is persisted as a bogus directory.
Normalize the value once in make. path is yielded later in make, so move that yield* above this line.

Linux x64, native standalone executables, fresh isolated state. On each commit, started the real service launcher with the CLI pointing to local release 0.1.8, requested 0.1.9 through the Update server client RPC, waited for the committed update and HTTP reconnection, then checked the server version, t3 --version, and symlink. Finally pinned the CLI back to 0.1.8 and restarted without another update.
The intentional 0.1.8 pin survived the later restart on both commits while the server remained on 0.1.9. Screenshots were stable across captures 500 ms apart.
Scope: real server/CLI behavior, with the service launcher run directly and locally cached release builds; desktop button interaction, OS service installation, and release downloading were not exercised.
AI-assisted; verified with the tests and tools listed above.
Not shown:
Desktop Update server button interaction and OS service installation: invoked the same client RPC and ran the real launcher directly to keep the host's installed service untouched.
Remote release downloading: used cached native executables built from each commit with synthetic release version metadata.
Custom installation directories, additional PATH aliases, foreign launchers, filesystem error handling, and macOS behavior were not exercised.
The eventual dangling-link failure after runtime pruning was not exercised; the immediate server/CLI version mismatch was reproduced.

Forward the install-bin override to the transient installer.
When an install runs inside the systemd service, the transient installer does not inherit the calling process’s T3CODE_INSTALL_BIN_DIR. It can retain the old unit value, although the returned plan reports the replacement. Pass the value explicitly; use an empty value when it is absent so the installer falls back to the saved unit value.
