extracted archive to name the j5 executable instead of t3; keep the existing
failure behavior unchanged.
Review comments at @scripts/build-cli-archive.ts:
- Around line 527-533: Add a Windows compatibility link in the archive-building
flow so the `win` platform archive includes `t3.exe` pointing to the existing
executable, while preserving the current non-Windows `t3` link behavior. Locate
the platform branch around `input.platform` and add the Windows-specific link
there.

| Left as upstream: archive file names (`t3-<version>-<platform>.tar.gz`, which existing servers download by name), tsdown's intermediate `dist-exe/t3`, and upstream's npm packaging (`scripts/build-npm-platform-packages.ts`, `packages/shared/src/legacyCliLauncher.ts`), which J5 doesn't publish. | ||

| **Transition link.** On macOS and Linux the archive also carries `t3 -> j5`. Service launchers and servers from before the rename look for `t3` in a new version's directory, and in-app updates never replace the launcher, so the link stays until a release removes it together with a `SERVICE_LAUNCHER_PROTOCOL` bump. Servers from after the rename then refuse the update with upstream's "update the launcher" message. Servers from before it never reach that check: their self-update verifies the staged `t3`, which won't exist, so the update fails with a generic install error and the running version stays. The smoke script runs both names. `.github/workflows/j5-release.yml` (J5-owned) verifies the macOS signature on `j5`. |

Correct the pre-rename self-update failure claim.
On macOS and Linux, the old installer extracts the archive before validating staged t3, and the archive includes t3 -> j5. With a matching release version and launcher protocol 3, preflight can pass and the old server can reach the launcher handoff. The missing-path failure applies on Windows, where the old verifier expects t3.exe and the archive has no transition link. Distinguish these cases.
Suggested documentation correction
-Servers from before it never reach that check: their self-update verifies the staged `t3`, which won't exist, so the update fails with a generic install error and the running version stays.

Review panel, second pass (Opus 5.5 code review, Astra live test), after the redesign in 441b03f. No findings on this PR.
Still not run by anyone: the service manager's own stop and start under the old CLI's |
The archive's executable kept upstream's `t3` name, so `~/.local/bin/j5` ran a file called `t3` and the server showed up as `t3`. Every place that locates the executable by name now says `j5`: the pinned runtime, the service launcher, SSH remote launch, both installers, the archive build and smoke, and the desktop WSL runtime. Each archive also carries a `t3 -> j5` link. Service launchers from before the rename start new versions as `t3`, and in-app updates never replace the launcher, so the link stays until a release drops it together with a SERVICE_LAUNCHER_PROTOCOL bump. install.sh links whichever name a release ships, so pinning an older version still works. Closes #403. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

CodeRabbit finding on #414: a rejected WSL runtime archive still reported a missing `t3` executable. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
An update from the app never replaces the service's launcher, and an old launcher starts every new version as `t3`. Rather than ship a `t3` link with no end date, the rename becomes launcher protocol 4: - a server from before it is refused the update from the app with a message to run `j5 update` on its machine; - that command, run by the old CLI, installs the new version, repoints the unit at the new launcher and starts it. The old CLI writes the state file as protocol 3, so the new launcher reads that too; otherwise it would exit and leave the server down until `j5 service install`; - the archive's `t3` link stays only so those servers can run that check and that command. Removing it is #440. Decided with Jackson on 2026-10-03. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The longer message was cut off in the app's update prompt. It now reads only "Run `j5 update` on the server's machine to finish it." Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Stack 1/5: the
j5command everywhere J5 is installed.Problem
The executable inside J5's release archives kept upstream's
t3name. So~/.local/bin/j5ran a file calledt3, the service unit rant3 __service-launcher, and the server showed up ast3. J5 shouldn't point att3at all. Closes #403.What changed
j5/j5.exe: the pinned runtime and the service launcher, SSH remote launch,install.shandinstall.ps1, the archive build and smoke scripts, the release workflow's signature check, and the desktop WSL runtime.t3-<version>-<platform>.tar.gz, because existing servers download updates by those names and users never see them.Moving existing servers across. An update from the app never replaces the service's launcher, and an old launcher starts every new version as
t3. Rather than ship at3link with no end date, each existing server is moved once, by hand:j5 updateon the server's machine to finish it." The server keeps running.j5 updateon that machine installs the new version and replaces the launcher. The old CLI writes the service's state file in the old format before starting the new launcher, so the new launcher reads that format too; otherwise it would exit and leave the server down untilj5 service install.t3link. Each macOS/Linux archive carriest3 -> j5, only because a pre-rename server runs that check and that command as<new version>/t3. Nothing after the rename looks for it. Removing it is Remove the t3 shortcut from release archives once pre-rename servers have updated #440.Not supported: downgrading below the rename with
j5 update --allow-downgrade.How it was checked. With a renamed 0.0.99 archive on a local mirror and a scratch home:
j5link, installed 0.0.99.j5 updatemessage.<version>/t3 __service-launcherover an old-format state file, it ran the server asj5.j5 update. It acts on the machine's real service, so it needs a throwaway machine. Jackson accepted shipping without it.Upstream impact
