📝 Walkthrough

Walkthrough

The change removes the unused Event import. It adds the github.copilot.viewsWelcome.invalidToken context key. waitForChatEnabled now sets this key based on whether copilotToken is undefined instead of waiting for a token event. Authentication changes update the same key.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to c0f1f

Invalid Copilot tokens can leave the Sign In welcome content hidden, so the context-key mismatch should be corrected before merge.

Full details: Rebase Rules For Upstream Changes

Explanation

The PR changes code/extensions/copilot/src/extension/authentication/vscode-node/authentication.contribution.ts. This path is under code/ and is not excluded by the code/extensions/che-* or lock-file exclusions. The file exists in both base and head, so the Che-only new-file exception does not apply. The PR changes no .rebase/ rule file, .rebase/CHANGELOG.md, or rebase.sh; no rebase rule references this source path. The supplied PR checklist also leaves all three Code-OSS override items unchecked.
