fix(web): onboarding Continue no longer locks on computers that won't connect

[juliusmarminge]

A user who updated an older client got stuck on the onboarding Connect your computers step: Continue stayed disabled no matter which computers they checked, including only the local one, which was connected.

Cause: Continue required every selected computer to be connected. The wizard auto-selects every saved computer, including ones that never connect by themselves: switched off (shown as "Not connected"), offline, stuck reconnecting, or unsupported. When T3 Connect is on, saved T3 Connect computers are also hidden from the top list, and the T3 Connect section only shows what the relay reports right now. So a stale saved entry could stay selected with no checkbox to clear it.

Fix:

• New resolveOnboardingSetup helper: Continue enables once at least one selected computer is connected and no selected computer is still on its first connection attempt. Selected computers that won't connect by themselves are skipped from setup rather than blocking it.
• Switched-off computers are no longer auto-selected. Users can still check them.

Known gap: a hidden computer whose first connection attempt hangs without failing would still keep Continue disabled. Closing that would need a timeout, so it's left out.

Verification: unit tests for the helper; existing wizard tests pass; web typecheck clean. Not reproduced in a real client, so there are no before/after screenshots.

📝 Walkthrough

Walkthrough

The onboarding wizard selects newly discovered environments only when enabled. It resolves setup readiness and environment IDs from selected environments’ connection phases. The connection step lists skipped environments, and saved cloud connection buttons use a shared presentation helper.

Onboarding Setup

Layer / File(s)	Summary
Resolve setup readiness apps/web/src/onboarding/targetEnvironment.logic.ts, apps/web/src/onboarding/targetEnvironment.logic.test.ts	resolveOnboardingSetup returns selected connected environment IDs and skipped IDs. Readiness requires at least one connected selection and no selected environment in the connecting phase. Tests cover connected, connecting, other phases, and no connected selection.

It uses resolved readiness and environment IDs for setup, lists skipped environments, and uses the shared helper for saved cloud connection button labels. Test fixtures mark their environments as enabled.

Merge Risk: 🔵 Low · up to bc7fe

A switched-off primary computer can still appear selected automatically. This is a bounded onboarding issue, but the fallback should honor the new opt-in behavior before merge.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR changes onboarding's default computer selection and the set of computers automatically sent through setup, in addition to fixing the Continue lockout. The behavior is localized and tested, but the product-default change requires human review.

🟡 Minor · Exclude a disabled primary environment from the fallback selection. · WelcomeWizard.tsx:148-155

apps/web/src/components/onboarding/WelcomeWizard.tsx:148-155
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exclude a disabled primary environment from the fallback selection.

When all newly discovered environments are disabled, selection remains null. The selectedIds fallback then selects the primary environment without checking entry.enabled. This marks the disabled primary row as selected, which violates the opt-in behavior stated by the effect comment. The readiness guard blocks setup, but it does not prevent the incorrect selection.

Suggested fix

-  const selectedIds =
-    selection ?? new Set(primaryEnvironment ? [primaryEnvironment.environmentId] : []);
+  const selectedIds =
+    selection ??
+    new Set(primaryEnvironment?.entry.enabled ? [primaryEnvironment.environmentId] : []);
