T3 Connect could show an environment as available while the relay had an activity-only link. Reconciliation skipped relinking because local state already said the tunnel was enabled, and Settings offered no repair action.

Fixes #11899.

What Changed

Compare local tunnel state with the existing relay discovery record. Show the mismatch in Connections and let Repair force a managed link while preserving the activity publishing setting. Normal publishing changes still avoid relinking when the modes agree. Explain activity-only links and full unlinking, and give web, desktop, and mobile users actionable connection-error text.

Why

Reuse the existing discovery map and link operation rather than add another backend API. Repair remains available when discovery cannot identify the mismatch. Server-side apply atomicity stays in #11898.

Verification

  • Reproduced before editing: the controller reported success but made zero link calls with local managed state and a publish-only relay record. The regression now passes.
  • 21 focused tests pass, including drift recovery during discovery refresh, explicit repair, preference preservation, unlinking, failure handling, discovery, and shared error presentation. Web and client-runtime typechecks pass. Targeted lint passes with one existing ConnectionsSettings memoization warning.
  • Isolated Chromium verified the actual Settings/controller flow with controlled auth, discovery, and link-operation fixtures: Repair, activity-only downgrade, full unlink, reconnect, and Repair with publishing disabled. Local server state was disposable; external requests were blocked. This does not verify live Cloudflare provisioning or a native mobile connection.
  • Independent Codex review: no findings. Claude was attempted first but unavailable.
  • No existing PR for this recovery gap was found. Rebased onto current main before opening.

UI Changes

Same drifted fixture before and after:

🟠 High cloud/useCloudLinkController.ts:133

Changing Publish activity during discovery refresh reports success without relinking a drifted environment, leaving the relay publish-only even though local state still says managed. Discovery clears environments, making managedTunnelOutOfSync false; include relayDiscovery.refreshing in the relink condition (or disable these controls while refreshing) so the managed mode is restored.

Confirmed and fixed in 7db4055. Reconciliation now relinks when refresh has temporarily cleared the environment record. A known matching record still avoids unnecessary relinking while status probes finish. The new regression failed before the fix and now passes; all 13 affected tests, targeted lint/formatting, and web typecheck pass.

🟠 High relay/errorPresentation.ts:47

For CLI hosts using publish_only, this message directs users to the host desktop app's Settings screen, which does not exist, so affected clients receive no actionable recovery path and remain unable to connect. Since apps/server/src/cli/connect.ts creates these links, tell users to run t3 connect again on the host instead.

Confirmed and fixed in 7db4055. The shared message now includes t3 connect for command-line hosts while retaining the desktop Settings/Repair path. Verified the CLI defaults to managed mode and updated the focused error-presentation test.

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — This is a focused, tested drift-repair bug fix that adds a deliberate Repair action and mismatch-triggered relinking without changing schemas, product defaults, or static-analysis configuration. Unresolved high-severity findings still identify a refresh-time relink gap and incorrect CLI recovery guidance, which remain separate risks for resolution.

Not approved because:

  • 2 blocking correctness issues found at or above your repo's Minimum Blocking Severity

📝 Walkthrough

Walkthrough

The controller detects relay managed-tunnel drift and supports forced repair. Connections settings exposes Repair and clarifies publish-only links. Relay errors and documentation provide recovery instructions for unmanaged endpoints.

Changes

Relay link repair

Layer / File(s) Summary
Controller reconciliation and validation
apps/web/src/cloud/useCloudLinkController.ts, apps/web/src/cloud/useCloudLinkController.test.tsx
Relay discovery detects provider drift. Reconciliation supports forceRelink, preserves publish-only links, unlinks when both capabilities are disabled, and reports failed link operations.
Connections repair UI
apps/web/src/components/settings/ConnectionsSettings.tsx
The settings row shows out-of-sync state, renders Repair for linked managed tunnels, forwards forceRelink, and shares switch disablement rules.
Endpoint error guidance
packages/client-runtime/src/relay/errorPresentation.ts, packages/client-runtime/src/relay/errorPresentation.test.ts, docs/user/remote-access.md
endpoint_provider_not_managed receives desktop Repair and command-line reconnection guidance. Tests and troubleshooting documentation cover the recovery instructions.
