Problem

With Local environment off, the desktop app hosts no server, but Settings → About → Update track → Nightly still blocked the switch with "This app cannot switch: its server is not connected, so its database cannot be checked." There is no database for this app to check, so the only way past the block was to turn Local environment on and start a second server.

Reproduced on the published 0.1.7 Stable Linux AppImage, with Local environment off and a separately run T3 server (from main, 6577c6b618) paired under Settings → Environments. Choosing Nightly (0.1.8-nightly.20261106.4262) showed the block, with "Switch to Nightly" disabled. With Local environment on and the app's own server connected, the same dialog allowed the switch.

Change

localSwitchBlockReason now also gets whether Local environment is on, and returns no block when it is off: this app's reinstall then restarts no server of its own. The dialog passes !isLocalEnvironmentDisabled().

It keys on the setting rather than on "no hosted servers and no desktop backends". That count is also zero while Local environment is on and the app's backend is still starting: the client registers that backend only after it answers, and the desktop leaves it out of its backend list until then. That case stays blocked. Remote servers' database checks are unchanged.

Scope and approval

Fixes pingdotgg/t3code#32018

Verification

vp test run apps/web/src/components/sidebar/updateEverything.logic.test.ts: 10 passed. The new case localSwitchBlockReason > does not block an app with Local environment off, which hosts no server fails on main with expected 'its server is not connected, so its database cannot be checked' to be null. Its second assertion keeps the case where Local environment is on and the backend has not appeared yet blocked.
vp run check:changed: passed.
Desktop, Linux: the published 0.1.7 AppImage shell with only its renderer rebuilt (APP_VERSION=0.1.7 vp build in apps/web, repacked into app.asar), once from the merge-base and once from this branch. Isolated profile, Local environment off, one remote environment paired and connected. Same server, release and steps on both sides. Electron 44 under Xvfb, DPR 1, no device emulation, prefers-reduced-motion: reduce, frozen clock. Steps: open About, choose Update track → Nightly, wait for the dialog to settle. "Switch to Nightly" was not clicked.

What else changed: the dialog is shorter by the removed warning, so its content shifts down and the button takes its enabled colour. The Environments and About pages before the dialog opens are identical at zero threshold. Nothing else differs.

The captures were made at 5c9c228b90. The head commit after it changes only a doc comment.

Not checked:

A newly built AppImage. This machine cannot build one, so only the renderer was rebuilt into the 0.1.7 shell.
macOS and Windows desktop.
Running the switch through to the reinstall.
Recordings of open → Cancel → reopen.
Other dialog states that the same unblock now reaches: Nightly → Stable, the macOS reopen note, running-thread footers, the skipped-machine list and a large fleet. Their rendering code is unchanged.
The driver and seeding scripts are not attached.

Approvability

Verdict: Approved at 1c913c7

Macroscope's review found this PR approvable — Track switching is no longer blocked by local database checks when Local environment is disabled and no local server runs. Compatibility safeguards remain unchanged for enabled local environments and remote servers.

Walkthrough

The track-switch guard now allows switching when the Local environment is disabled. The dialog passes the environment state to the guard, and tests cover enabled and disabled cases.

Changes: Local-environment track switching

Layer / File(s)	Summary
Track-switch guard and tests `apps/web/src/components/sidebar/updateEverything.logic.ts`, `apps/web/src/components/sidebar/updateEverything.logic.test.ts`	`localSwitchBlockReason` accepts a Local-environment flag and returns no block when it is false. Tests cover disconnected and starting backends.
Dialog passes Local-environment state `apps/web/src/components/settings/UpdateTrackSwitchDialog.tsx`	The dialog passes whether the Local environment is enabled to `localSwitchBlockReason`.

Explanation

[#32018] UpdateTrackSwitchDialog.tsx passes the Local environment setting to localSwitchBlockReason. When Local environment is off, the function allows the track switch. When it is on, the existing hosted-server and backend checks still block an unchecked database. The tests cover the Local-off case and the still-starting backend case.

Issue watch picked up https://github.com/pingdotgg/t3code/issues/32018 after this PR was already open. At main d5fc29fe5cb62db68bfbf824cfabe0ae94ac6ac4, the guard still rejects an empty hosted-server list. We found this PR before implementing or launching a desktop reproduction, so there are no independent runtime results to add. Handing the issue back to this PR and stopping our duplicate work.

Check retained databases before switching tracks.
If Local is disabled after a newer migration, the switch can install an older server without checking the retained database. Re-enabling Local starts that server on the database. For example, a server predating migration 80 can run a fresh_session scheduled task with its previous context.
Check retained local databases before the switch, while still allowing it when no local database exists.

Evidence

On both commits: start a separately managed server; open the desktop app; turn Settings → Environments → Local environment off and restart; pair and connect the separate server; open About → Update track → Nightly.

Environment for every capture: Linux desktop under headless-desktop, Electron 44.10.1, production-mode source assembly, 1280×900 viewport, light theme, fresh isolated state without history imports. Recordings begin with Local off and the separate server Connected. Private labels and launcher paths are redacted; captions sit above the application viewport.

Before	After
d290c1f1b6	1c913c74b4
Interaction recording	Interaction recording
Before: Local off and separate server connected	After: Local off and separate server connected
Before: disconnected-server warning disables confirmation	After: warning absent and confirmation enabled

Base shows “its server is not connected, so its database cannot be checked” and disables confirmation. Head enables confirmation without that warning. Both resolve the same Nightly release and retain one skipped separate server.

Interaction driver, pairing driver, desktop assembly, capture processing, setup and limitations.

AI-assisted; verified with the tests and tools listed above.

Not shown:

Download, installation, and successful completion of the track switch were not attempted; evidence stops at the confirmation guard. The generic updater's startup check encountered ERR_CERT_DATE_INVALID, while the real server's registry lookup succeeded on both sides.
Other separately managed server compatibility outcomes and additional app-hosted server configurations were not exercised; this reproduction retained the same skipped separate-server row on both sides.
Signed release and installer behavior were not exercised; both sides ran production-mode Electron assemblies built from their respective worktrees.
